San Onofre Nuclear Generating Station, the twin-reactor power plant that spread its isotopic glow across coastal communities from Los Angeles to San Diego, was declared dead last week. SONGS, as it was affectionately known, was 44, though many of its parts are considerably younger.
Originally conceived as a single Westinghouse pressurized water reactor in 1964, San Onofre was officially commissioned on January 1, 1968. Two additional units were brought online in the early 1980s. The original Unit 1 was closed permanently in 1992, and stands as a radiant monument to nuclear’s 20th Century aspirations.
With its proximity to seismic fault lines and a history of accidents, security breaches and safety complaints, SONGS has long been deemed one of the most difficult siblings in its nuclear family. Units 2 and 3 have been offline since January of this year due to a leak of radioactive steam from a heat transfer tube. Subsequent inspections of the tubes–completely redesigned and replaced when SONGS got an extreme makeover in 2010 and 2011–revealed alarming rates of wear previously unseen at any similar facility. Both reactors have been considered too damaged to simply restart since the initial discovery.
Though multiple scientists, engineers, public interest groups and government agencies diagnosed San Onofre’s troubles as terminal early in the year, Southern California Edison and San Diego Gas & Electric, SONGS’ “guardians” held out hope (or more likely just put on a brave face for the sake of family and friends–also known as “shareholders”) that their beloved ward could be revived. A decision last month to remove the nuclear fuel from Unit 3 made it hard to maintain that façade, and news late last week that the utilities were planning for a 2013 summer without any power produced or transferred by San Onofre made it clear that even SONGS’ oldest friends understood it was time to “pull the plug,” as electrical types are wont to say.
San Onofre is survived by its California cousin, Diablo Canyon, and 100 other frail and faltering nuclear reactors nationwide. At the time of this writing, funeral arrangements have still not been made official.
* * * *
And there’s the rub. While it is the present reality and the obvious future, the final shuttering of San Onofre has not been made official. Not by its operators, and not yet even by the California Public Utilities Commission. Acknowledging the nuclear plant’s demise would trigger a review process that would result in rate reductions for Edison and SDG&E customers. Those reviews will kick in automatically in a couple of months because SONGS has failed to generate a single kilowatt of electricity from February on, but the owner-operators of the plant have fought to drag the process out to its longest legal limit, despite the widespread understanding that a restart of even one reactor is at best very far off and likely just never to be.
With this reality universally understood and effectively acknowledged by all parties, the NRC should stop wasting resources on any plan for a restart, and start asking the tough questions about decommissioning SONGS. And it borders on corrupt that SCE and SDG&E are still charging ratepayers $54 million a month for service not rendered, with no promise that it ever will be. The California PUC should remove San Onofre from the utilities’ rate base now.
Consumer advocate Matt Freedman of The Utility Reform Network (TURN) sees this idea for what it is–socialized risk, privatized return:
“It‘s a maxim of retirement planning that as you get closer to your own personal retirement, your investments get more conservative,” Freedman said, “not more risky. But in this case, Commissioner Simon is suggesting that as these units near their retirement, that we should begin to invest more of the money in very risky investments.”
Freedman said the proposal on the table appears designed to benefit investment managers who would charge higher fees for new categories of investments. He said without a lot of time to ride out market fluctuations, ratepayers could be left on the hook for any depletion of the fund caused by market drops.
Naturally, San Diego Gas & Electric finds Simon’s idea appealing, but in the same breath, the company notes such a move means higher fees–fees that could be passed on to ratepayers with CPUC approval. It appears to be another sign that the utilities are looking to cash in before San Onofre officially is forced to check out.
But in times of trouble, responsibility ultimately rests with the family (aka the shareholders) to confront the hard truths. Owners of Edison and SDG&E stock should demand that the boards of these companies stop wasting shareholders’ money and everyone’s time and get on with divesting from their dirty, dangerous, and expensive involvement with nuclear power.
To paraphrase the United States Nuclear Regulatory Commission, Merry Effin’ Christmas.
In a news dump that came a day early (because who really wants to dump on Christmas-Eve Eve?), the Nuclear Regulatory Commission made a pair of moves Thursday that could have significant consequences for America’s nuclear industry–and all the people who have to live with it.
The Nuclear Regulatory Commission unanimously approved a radical new reactor design on Thursday, clearing away a major obstacle for two utilities to begin construction on projects in South Carolina and Georgia.
Whoa–let’s stop it there for a sec. . . . A “radical new reactor design?” Somebody’s being a good little scribe this Christmas. As previously discussed, there is nothing radical about the AP1000–it’s a tweak on the generations-old pressurized water reactor design that theoretically would allow the core to avoid a meltdown in the event of a total loss of AC power. . . .
Well, for 72 hours, anyway.
After that, the manufacturer–in reality the Japanese owner of Westinghouse, Toshiba–says something about it taking only “minimal operator effort” to avert disaster.
Keep in mind that the AP1000 was designed well before the Japanese earthquake and tsunami that started the ongoing Fukushima disaster, but this approval, of course, comes well after.
Designers of the AP1000 assert that gravity and convection will serve to keep reactor cooling functioning even if systems are disabled as they were at Fukushima. That assertion is predicated on the storyline that the Daiichi plant’s safety systems survived the massive quake, and only ran into trouble when the tsunami flooded and disabled the diesel backup generators that powered cooling systems for the reactors and the spent fuel pools.
That is a capricious assertion for two very disturbing reasons:
First, it is by no means established fact that Fukushima’s cooling systems survived the earthquake undamaged. Reports from the Japanese government and TEPCO, Fukushima Daiichi’s owner-operator, have gone back and forth on this matter. It would be naturally beneficial to nuclear advocates to go with the story that the quake did nothing to the reactor and its safety systems. But given the visible damage to the plant and the surrounding area, and given the profound leaking of cooling water that has continued seemingly unabated from the earliest days of the disaster, it is hard to believe all pipes, tubes, couplings, fittings, vents and valves–not to mention the containment vessels and tanks themselves–remained watertight after the massive temblor.
Just days before the earthquake in Japan, Rep. Markey wrote a letter to the NRC urging the Commission not to approve the Westinghouse AP1000 design until serious safety concerns were addressed. One of NRC’s longest-serving staff, Dr. John Ma, had warned in NRC documents that the reactor’s containment could shatter “like a glass cup” due to flaws in the design of the shield building if impacted by an earthquake or commercial aircraft. The shield building has the critical safety function of preventing damage to the reactor that could cause fuel meltdowns and radiation releases.
Note, Dr. Ma has been with the NRC since its inception, and this was the first non-concurrence dissent of his career. The NRC acknowledged this concern and asked Westinghouse for a response. . . and the response was, essentially, “nah-ah.” A response that has now proven good enough for the agency tasked with assuring the safety of America’s nuclear reactors.
So, it theoretically would be great if the AP1000 were able to survive without melting down through three days without electrical power–though it should be noted that three days wouldn’t have really saved Fukushima’s bacon (even if it had remained intact) given the devastation to the region’s infrastructure. But that semi-sunny selling point on the AP1000 assumes that there would still be a reactor containment building to cool.
It is the kind of “what could possibly go wrong” assumption that has tripped up nuclear power generation in large and small ways throughout its history–and it is stunning that, especially in the wake of the Japanese crisis, this cavalier attitude continues.
But perhaps it is not so surprising when we consider just why the AP1000 has such a novel/brittle containment building: it is supposedly cheaper to build.
The AP1000 is slated to have a smaller footprint with fewer components, but still use off-the-shelf, previous-generation parts. Most notably, the design uses under a fifth the amount of concrete and rebar, compared with existing PWRs.
In an unusual step, the commission waived the usual 30-day waiting period before its approval becomes official, so its decision will be effective in about a week. That moves the utilities closer to the point where they can start pouring concrete for safety-related parts of the plant.
The decision also moves the industry toward the first test of a streamlined procedure in which the commission will issue a combined construction and operating license. Up to now reactors had to obtain a construction license and then undergo a long wait for an operating license, resulting in expensive delays in starting up reactors that had essentially been completed.
The approval of a shaky design is disturbing, but the approval of a process that will allow that design to move to completion and operation with far fewer pauses to test safety is unconscionable. (And the fact that this happening because of bottom-line concerns is criminal.) As the distinguished gentleman from Massachusetts put it:
“Today, the NRC has presented its holiday gifts to the nuclear industry,” said Rep. Markey, top Democrat on the House Natural Resources Committee and a senior member of the House Energy and Commerce Committee. “Instead of doing all they should to protect nuclear reactors against seismically-induced ground acceleration, these Commissioners voted to approve the acceleration of reactor construction. While they continue to slow walk the implementation of recommendations of the NRC professional staff’s Near-Term Task Force on Fukushima, they have fast-tracked construction of a reactor whose shield building could ‘shatter like a glass cup’ if impacted by an earthquake or other natural or man-made impact.”
It is not the first time those wary of a nuclear renaissance had been presented with the dilemma of both praising and cursing Jaczko. In fact, just last week, on December 15, Jaczko was the only vote in support of a move to make all recommendations of the post-Fukushima Near-Term Task Force report mandatory for the “adequate protection” of nuclear power plants. The four other NRC commissioners asserted that it was “premature” to make such a rule–and so Fukushima’s lessons continue to go unlearned, over Jaczko’s protestations and lonely protest vote.
But it is just this sort of nightmare-inducing nuclear mollycoddling that should convince Jaczko that the process he has often praised is deeply flawed. He cannot advocate for new safety rules one week and then grant license to the industry that works so hard against those rules the next. Not if he really wants change; not if he really cares about public safety.
In the immediate aftermath of the Japanese earthquake and tsunami that triggered the horrific and ongoing disaster at the Fukushima Daiichi nuclear power generating station, President Barack Obama went out on a bit of a limb, striking a tone markedly different from his fellow leaders in the industrialized world. Speaking about Japan and its effect on America’s energy future–once within days of the quake, and again later in March–the president made a point of reassuring Americans that his commitment to nuclear power would stay strong. While countries like Germany and Japan–both more dependent on nuclear power than the US–took Fukushima as a sign that it was time to move away from nuclear, Obama wanted to win the future with the same entrenched industry that so generously donated to his winning the 2008 election.
But a funny thing happened on the way to winning our energy future–namely, our energy present.
As November drew to a close, an article on AOL Energy (yes, it seems AOL has an energy page) declared 2011 to be “nuclear’s annus horribilis“:
March 2011 brought the 9.0 magnitude earthquake off northeastern Japan that sparked a tsunami whose waves may have exceeded 45 feet. Tokyo Electric Power Company’s oldest nuclear station, Fukushima Daiichi, apparently survived the earthquake, but its four oldest reactors didn’t survive that wall of water. Nuclear experts are still figuring out what all went wrong, and tens of thousands still haven’t returned home as Japanese authorities try to decontaminate radioactive hot spots.
In April, massive tornadoes that devastated the southeast swept near the Tennessee Valley Authority’s Browns Ferry plant.
In June, droughts sparked wildfires across the Southwest, including one that threatened the Los Alamos National Laboratory, where nuclear weapons materials are stored.
June also brought record floods across the upper Midwest. For weeks Omaha Public Power District’s Fort Calhoun nuclear plant was essentially an island.
August saw the 5.8 magnitude Virginia earthquake just 11 miles from Dominion Energy’s North Anna plant. The plant shut safely, and returned to service mid-November after extensive checks found no damage even though ground motion briefly exceeded the plant’s design.
That list, as readers of this space will no doubt note, is far from complete. This year has also seen serious events at nuclear plants in California, Maryland, Michigan, New Hampshire and Ohio. But, perhaps even more troubling is the strangely positive tone of the piece.
Despite its ominous headline, it seems the message is: “Yeah, lots of nasty business in 2011, but 2011 is almost over. We got through it and no one died (at least no one in the US), so. . . problem solved!” It’s an attitude absurd on its face, of course, the passage of time is not the friend of America’s aging nuclear infrastructure–quite the opposite–but it is also a point that can’t survive the week in which it was made.
Take North Anna, for example. Yes, it is true that the NRC signed off on a restart in the waning hours of November 11, but the two generators at Dominion’s plant were not back at full power till November 28 because there was indeed damage–some of which was not discovered until after the restart process began.
A week earlier, a fire at Ohio’s crippled Davis-Besse facility cut ventilation to the reactor control room. A faulty valve in a pipe sending water to the reactor core leaked on an electrical switchbox, triggering an electrical arc, which started the fire. This could have been a potentially catastrophic emergency. . . had the reactor not been shut down seven weeks earlier to replace an already once previously replaced, corroded, 82-ton reactor lid. This “transplant operation” revealed a 30-foot crack in the concrete shield building that will require a separate repair program. . . which will in no way be completed before the end of the year.
The day after that fire, November 20, the St. Petersburg Times reported that Progress Energy’s Crystal River nuclear power plant in Citrus County, Florida, had discovered a 12-foot by 4-foot crack and crumbled concrete in its containment building in late July, but failed to notify the Nuclear Regulatory Commission. This was a patently intentional omission, as Progress Energy was already reporting to the NRC about repairs to two other major cracks in the same building dating back to October 2009 and March 2011.
The Crystal River story is long and sordid. The containment building cracked first during its construction in 1976. That crack was in the dome, and was linked to a lack of steel reinforcement. Most nuclear plants use four layers of steel reinforcement; Crystal River used only one. The walls were built as shoddily as the dome.
The latest problems started when Crystal River needed to replace the steam generator inside the containment building. Rather than use an engineering firm like Bechtel or SGT–the companies that had done the previous 34 such replacements in the US–Progress decided it would save a few bucks and do the job itself.
Over the objections of on-site workers, Progress used a different method than the industry standard to cut into the containment building. . . and that’s when this new cracking began. It appears that every attempt since to repair the cracks has only led to new “delamination” (as the industry calls it).
At this point, most have determined that the best plan going forward is to tear down the substandard structure and build a properly reinforced new one, but Progress thinks they have a better idea. Crystal River’s operator is trying to replace the wall panels–all six of them–one by one.
Funny enough, the cost of this never-before-tried retrofit is about the same as the cost of a whole new building. But the full rebuild would take more time–and there’s the rub.
Every day that Crystal River is offline costs Progress money because they have to buy energy to replace what they agreed to provide to the region from this nuclear facility. Each year that the plant is offline is said to cost $300 million. The price tag on this little cracking problem so far–not counting the actual costs of the repair–is $670 million.
Customers will pay $140 million next year so Progress Energy Florida can buy electricity from other sources while a nuclear plant remains shut down for repairs.
Consumer advocates opposed the power replacement charge, which will take effect Jan. 1, but it won unanimous approval Tuesday from the five-member Florida Public Service Commission.
The panel’s decision is a prelude to a determination next year whether a portion of the repair costs should be passed on to customers or paid in full by the company’s investors owing to problems that have delayed the work. The Crystal River plant was closed for repairs in 2009 but now isn’t expected to reopen until 2014. That’s about three years later than initially expected.
The repair bill is expected to total $2.5 billion. The utility wants customers to pay $670 million, or about a quarter of that amount.
Interesting how that $670 million exactly mirrors the replacement energy costs through today. Students of the Florida Public Service Commission would probably be skeptical that the bailout will really stop there–remember, Florida residents already pay a surcharge on their utility bills for possible (but in no way guaranteed) future nuclear power construction.
And to say that it’s all about the money would not be pure speculation. As the St. Petersburg Times reports, while the good people at Crystal River failed to notify the NRC (or the Public Service Commission) about their latest troubles in a timely fashion, Progress Energy didn’t dare keep secrets from the US Securities and Exchange Commission. On August 8, the same day it neglected to mention the new cracks in a report to the PSC, Progress filed its annual report to the SEC and stated “additional cracking or delaminations may have occurred or could occur during the repair process.”
Given the many revelations of just how casual SEC enforcement can be, it is disturbing to think a nuclear provider had more to worry about from the SEC than from the NRC, the agency given direct oversight of nuclear plant licensing and safety.
Disturbing, but not surprising. This year has also revealed the cozy relationship between the nuclear industry and the NRC. An AP exposé made that clear over the summer, but one need look no further than the AOL Energy story:
[Nuclear Energy Institute CEO Marvin] Fertel said the industry and NRC are “in very good alignment” on the issues raised by 2011 events. The concern for utilities is the “cumulative impact” of new rules, he said, and making sure they’re ranked so plant staffs attack those with the most safety benefit first and the cost is manageable.
The government and the industry agree–safety must be addressed with an eye toward cost. And the tens of millions of Americans living in the shadow of a nuclear reactor will see just what this means as the watered-down post-Fukushima recommendations are slowly proposed and implemented–with little fully required of plant operators before 2016.
Indeed, the global nuclear industry is proceeding not just as if it is business as usual–when it comes to the United States, manufacturers of nuclear plant components are already betting on a new wave of reactor construction. Over the Thanksgiving weekend, Yomiuri Shimbun reported that Toshiba Corp. is preparing to export turbine equipment to the US.
The turbines are for Toshiba-owned Westinghouse Electric Company-designed AP1000 reactors proposed for sites in Georgia and South Carolina. As previously reported, the AP1000 is a new reactor design–a new design that has not yet officially been approved by the Nuclear Regulatory Commission. Still, the operators of the plants have already started to procure the equipment.
All of which raises the question, how is it that, in an age when credit is so hard to come by, an industry so focused on the bottom line feels secure in moving forward with commitments on a plan that is still officially going through the regulatory pipeline?
The assurances come from the top, and so does the money.
In contrast to pledges to, say, close Guantanamo or give Americans a public health insurance option, when it comes to nuclear power, Barack Obama is as good as his word. In February, Obama pledged $8.33 billion in federal loan guarantees to Southern Co., the operator of Georgia’s Plant Vogtle, the proposed home of two new AP1000 reactors. Again, this pledge came in advance of any approval of the design or licensing of the construction.
So, perhaps the nuclear industry is right to feel their “annus horribilis” is behind them, at least when it comes to their business plans. And with the all-too-common “privatize the profits, socialize the risks” way the utilities are allowed to do business, one might even doubt this last annus was really that horribilis for them at all.
But for the rest of us, the extant and potential problems of nuclear power are not limited to any particular period of time. The dangers of nuclear waste, of course, are measured in tens of thousands of years, the Fukushima crisis is lived by millions every minute, and the natural disasters, “events” and accidents that plague an aging, expensive and insufficiently regulated American nuclear industry are an anytime, anywhere reminder that future cannot be won by repeating the mistakes of the past.
As September drew to a close, residents of southwest Michigan found themselves taking in a little extra tritium, thanks to their daily habit of breathing (h/t emptywheel). The tritium was courtesy of the 40-year-old Palisades Nuclear Generating Station in Covert Township, which suffered its third “event” (as they are politely called) in less than two months, and was forced to vent an indeterminate amount of radioactive steam.
While it is nice to see rectors shut themselves down when a vital system goes offline, remember that “turning off” a fission reactor is not like flicking a light switch. Shutting down a reactor is a process, and the faster it is done, the more strain it puts on the reactor and its safety and cooling systems. And even after fission is mitigated, a reactor core generates heat that requires a fully functional cooling system.
Which is kind of an interesting point when considering that Palisades had just been restarted after completing repairs to a breach in the cooling system that was reported to be leaking more than 10 gallons per minute. Prior to that, a “special inspection” was ordered August 9 after a pipe coupling in the plant’s cooling system failed.
(By the way, have no fear, Michiganders, a public affairs representative for the Nuclear Regulatory Commission reassured the public that the concentration of tritium was “far below regulatory releases,” and that “as soon as it goes out, it gets diluted further.” You know, in the air. . . that you breathe.)
News of the Palisades tritium burp came at roughly the same time as a breathless (if a press release can be breathless) announcement from Dominion Resources, the folks responsible for the North Anna nuclear plant, the facility that scrammed after being shaken beyond design specifications by the earthquake centered in nearby Mineral, Virginia:
Our investigation showed the units tripped before the loss of off-site power when multiple reactor sensors detected a slight power reduction in the reactors. . . .
The root cause team determined that this occurred as result of vibration in the reactor or the monitoring devices in the reactors, or both.
Again, good that the reactors scrammed when something registered the quake, but noteworthy again because it was previously believed that the automatic shutdown started as a result of a loss of power–power required to operate the cooling systems, not only for the reactors, but for the spent fuel pools, as well.
This is not just a perpetual motion machine laugh line. This inherent flaw in the design of LWRs is at the root of two other prominent tales of nuclear safety (or lack thereof).
The first, of course, is the ongoing, ever-metastasizing disaster in Japan, where failures in the cooling systems at Fukushima Daiichi following a massive earthquake and tsunami resulted in hydrogen explosions, core meltdowns, and, likely, melt-throughs that contaminated and continue to poison sizable portions of the country and surrounding sea.
The second story concerns the proposal for the construction of two new reactors at Plant Vogtle, a nuclear power facility near Augusta, Georgia.
The Vogtle reactors would be the first to be built in the US in a generation, and they have come under some additional scrutiny in part because they would be the first of a new-design LWR called the AP1000. A riff on previous Toshiba/Westinghouse pressurized water reactors, the AP1000′s most noticeable “innovations” are meant to address the active cooling paradox. First, it has emergency “dump tanks,” reservoirs of water situated above the reactor that could, in an emergency, empty into the reactor via gravity, providing up to 72 hours of “passive” cooling. Second, rather than housing the core in a reinforced concrete shell with a metal liner, the AP1000 would have an all-steel containment vessel which would, in theory, be able to expel heat through convection.
While these two design features both highlight and attempt to address a dangerous flaw that is a part of every other nuclear facility in the United States–that water has to be actively cycled through a reactor core to keep it from melting–the design still predates the Fukushima quake, and fails to truly incorporate the lessons of that disaster.
The massive March 11 earthquake shutdown power to the Fukushima Daiichi plant, and thus the cooling systems, and the tsunami that followed flooded the diesel-powered backup generators, but that was only part of the problem. Investigations now show that even if Fukushima had in some way managed to maintain power, the cooling system would still likely have failed for at least some (and likely all) of the reactors, and (and this is important) for the spent fuel pools, as well. That is because the quake not only caused a loss of power, it also caused numerous breaches in the cooling system. Cracks in the containment vessel, broken pipes, and dislodged couplings would have likely resulted in a calamitous drop in water levels, even with full power. Less than successful attempts to restore the cooling systems with new, external power sources, and the large amounts of contaminated water that continue to pour from the plant, have demonstrated just how severely the physical infrastructure was damaged.
There are additional concerns about the design of the AP1000 (possible corrosion of the all-metal containment vessel and less than rigorous computer modeling of seismic tolerances, for instance), but, in a post-Fukushima world, simply addressing the active/passive cooling problem (and only doing so for the reactor and not the spent fuel pools) does not promise a safe nuclear facility.
The chairman of the U.S. Nuclear Regulatory Commission says the agency may need to incorporate its findings about a nuclear disaster in Japan into a license to build a new nuclear plant in Georgia.
NRC Chairman Gregory Jaczko said Wednesday [September 28] he believes the license to build two more reactors at Plant Vogtle near Augusta should include conditions that reflect the findings of a review of this year’s disaster at the Fukushima Dai-ichi plant.
While it is true that “may” and “should” are not “will” and “must,” and it is also the case that the Fukushima taskforce recommendations themselves do not fully address the problem outlined here, Chairman Jaczko’s comments do make the point that there are indeed lessons to be learned from the Japanese crisis, and right now, in the US, that education has not taken place.
The chairman and his fellow commissioners have wrestled all summer with the pace of post-Fukushima reform. Jaczko has argued for what in NRC terms is considered a speedy consideration of the new safety regime, but a majority of the panel has managed to slow the process down to a point where no new regulations will likely be in place by the time the NRC is required to rule on the Vogtle permits.
But, because the Vogtle hearings have revealed the Chairman’s understanding of at least some of the problems, it also reveals an obvious path for Jaczko and those (such as Senator Barbara Boxer (D-CA)) who would also want any new construction or operating permits to only be approved under guidelines drafted in response to the Fukushima disaster. If the industry–and the commissioners most friendly to it–wants to move quickly ahead on new construction and the relicensing of 40-year-old plants, then it should be required that they move quickly on adopting the Fukushima taskforce recommendations. No new safety rules, no new permits–the political calculus should be that simple.
And, if the NRC won’t do the political math, then it should be up to elected government to run the financial numbers.
Building the new Vogtle reactors is projected to cost $14.8 billion. That’s projected–the existing Vogtle plant went over budget by a factor of 14. But even if the new reactors stay on budget, there is still no way they would get built without help from the Federal Government. To that end, the Obama administration okayed an $8.33 billion loan guarantee for The Southern Company, owners of Plant Vogtle, contingent on the NRC’s approval of the plans. (By way of comparison, that is 16 times the size of the loan given to the now-defunct solar technology company Solyndra.) While there are a myriad of reasons why that and other such guarantees should never be proffered, at minimum, the federal government should now freeze the financial backing for new construction until the NRC passes–and industry adopts–an enhanced safety regime.
This wouldn’t be a one-shot power play. Hot on the heals of Vogtle, the V.C. Summer nuclear facility in South Carolina is also looking to add two new AP1000 reactors, and its permit process is also underway. And financial markets understand what a bad bet that project is, too. Summer is also owned by Southern, but it is operated by SCANA. Moody’s, the bond-rating agency, just downgraded SCANA’s debt to one notch above “junk” status, citing the cost of the proposed new reactors.
Meanwhile, the Commonwealth of Virginia has handed over $7 million in precious state funds to North Carolina’s Babcock & Wilcox to open a prototype of a small modular reactor (SMR) in the town of Forest, near Lynchburg. The SMR is small, indeed–160 megawatts (in contrast to the 1,800 megawatt capability of Virginia’s North Anna plant)–and it’s built entirely underground, supposedly enhancing its safety when faced with a potential terrorist attack. How it will provide greater protection from an earthquake or flood seems (at best) less obvious.
Yet, with all of this action, all of these new designs, all of this lobbying, and all of this (as “serious” people repeatedly caution) scarce government money, still no one is addressing another part of the nuclear equation: spent fuel. With Yucca Mountain now (supposedly) abandoned, the United States has no long-term plan for handling the already large and ever-growing problem of dangerous spent nuclear fuel. Right now, each nuclear facility stores its used fuel in either pools, dry casks, or both. The spent fuel pools require an active cooling system, which faces most of the same problems inherent in reactor cooling. Dry casks–used for fuel that is cool enough to remove from the pools–are considered safer, but they are far from “safe.” They are above ground, emit some radiation, and are theoretically vulnerable to terrorist attack (and the casks at North Anna moved and sustained “cosmetic” cracks in the August earthquake). In many US plants, both pools and casks are already filled to capacity. Expanding the number of nuclear reactors only accelerates the storage crisis.
And it must be reiterated, all of this activity comes a mere six months after the start of the Fukushima disaster. The latest announcement from the Japanese government–that they will relax the evacuation order for more than 100,000 residents even though their towns have not yet been decontaminated–says nothing about an easing of the emergency, and everything about a government that frankly just doesn’t know what else to do. The United States, though obviously larger, has reactors near enough to densely populated areas that a nuclear accident would make Japan’s evacuation problem seem like a rush hour fender bender. And the US government’s plan to deal with a nuclear disaster is no more impressive than Japan’s.
The saddest part, of course, is that it needn’t be that way. Beyond the political and financial tools proposed above, the NRC actually already has the power to demand the nuclear industry own up to the new seismic reality. When Westinghouse Electric came before the commission in May, it was ordered to fix its seismic calculations. Though Westinghouse grumbled, it did not question the NRC’s authority to rule on seismic concerns.
Nuclear regulators already have “sufficient information and knowledge” to deal with earthquake risks at existing U.S. reactors and don’t need to wait for a broader review, a safety advocate said.
The Nuclear Regulatory Commission developed seismic rules for new plants in 1996 and has since approved preliminary construction for proposed nuclear units at a Southern Co. plant in Georgia and certified an early reactor design by Toshiba Corp.’s Westinghouse Electric unit, according to comments filed with the agency today by David Lochbaum. . . .
“If the NRC truly lacks sufficient information about seismic hazards and how safety at nuclear power reactors is affected, then the agency cannot responsibly have issued early site permits and certified new reactor designs,” he said.
Of course, having the authority and exercising it are not the same thing, but just as the NRC is not truly handcuffed by the fight over the Fukushima taskforce recommendations, the entire country need not be shackled to such a flawed, dangerous and expensive energy source as nuclear. The US government has demonstrated that it has the authority to make decisions on energy sources, and it has shown that it actually has the money to invest–big money. Of course, be it the NRC, Congress or President Obama, when it comes to moving beyond nuclear to demonstrably safer and truly renewable sources, what the US has not shown is the will.
