NRC Cites San Onofre Nuclear Plant for Lapse in Security

The US Nuclear Regulatory Commission hit Southern California Edison’s San Onofre Nuclear Generating Station (SONGS) with a violation for what it called a lapse in plant security, the agency announced late Thursday.

The NRC noted the violation during a four-day inspection in May. SONGS has been completely offline since January, when a radioactive leak led to the discovery of severely degraded heat exchanger tubes in both of the plant’s (nominally) operating reactors. (In July, the NRC released its report on the tube failures, saying that although plant operators had made major design changes that affected the stability of the tubes, they had not violated any laws.)

Regulators said Edison “failed to develop procedures to monitor electronic devices related to security,” but the NRC has withheld most of the details of the violation.

San Onofre has a long list of safety and security problems dating back long before the latest tube debacle. In January, around the same time as the radioactive leaks, a SONGS worker accidentally fell into one of the facility’s spent fuel storage pools while trying to retrieve a dropped flashlight. And just two weeks ago, an investigation uncovered a staggering number of fire safety violations that continue to go uncorrected, despite previous NRC warnings.

For Nuclear Power This Summer, It’s Too Darn Hot

7:59 am in Uncategorized by Gregg Levine

You know that expression, “Hotter than July?” Well, this July, July was hotter than July. Depending on what part of the country you live in, it was upwards of three degrees hotter this July than the 20th Century average. Chicago, Denver, Detroit, Indianapolis and St. Louis are each “on a pace to shatter their all-time monthly heat records.” And “when the thermometer goes way up and the weather is sizzling hot,” as the Cole Porter song goes, demand for electricity goes way up, too.

During this peak period, wouldn’t it be great to know that you can depend on the expensive infrastructure your government and, frankly, you as ratepayers and taxpayers have been backstopping all these years? Yeah, that would be great. . . so would an energy source that was truly clean, safe, and too cheap to meter. Alas, to the surprise of no one (at least no one who watches this space), nuclear power, the origin of that catchy if not quite Porter-esque tripartite promise, cannot.

Take, for example, Braidwood, the nuclear facility that supplies much of Chicago with electricity:

It was so hot last week, a twin-unit nuclear plant in northeastern Illinois had to get special permission to continue operating after the temperature of the water in its cooling pond rose to 102 degrees.

It was the second such request from the plant, Braidwood, which opened 26 years ago. When it was new, the plant had permission to run as long as the temperature of its cooling water pond, a 2,500-acre lake in a former strip mine, remained below 98 degrees; in 2000 it got permission to raise the limit to 100 degrees.

The problem, said Craig Nesbit, a spokesman for Exelon, which owns the plant, is not only the hot days, but the hot nights. In normal weather, the water in the lake heats up during the day but cools down at night; lately, nighttime temperatures have been in the 90s, so the water does not cool.

But simply getting permission to suck in hotter water does not make the problem go away. When any thermoelectric plant (that includes nuclear, coal and some gas) has to use water warmer than design parameters, the cooling is less effective, and that loss of cooling potential means that plants need to dial down their output to keep from overheating and damaging core components. Exelon said it needed special dispensation to keep Braidwood running because of the increased demand for electricity during heat waves such as the one seen this July, but missing from the statement is that the very design of Braidwood means that it will run less efficiently and supply less power during hot weather.

Also missing from Exelon’s rationale is that they failed to meet one of the basic criteria for their exception:

As World Honors Fukushima Victims, NRC Gives Them a One-Fingered Salute

8:45 am in Uncategorized by Gregg Levine

Nearly a week after the first anniversary of the Japanese earthquake and tsunami that started the crisis at the Fukushima Daiichi nuclear power facility, I am still sorting through the dozens of reports, retrospectives and essays commemorating the event. The sheer volume of material has been a little exhausting, but that is, of course, compounded by the weight of the subject. From reviewing the horrors of a year ago–now even more horrific, thanks to many new revelations about the disaster–to contemplating what lies ahead for residents of Japan and, indeed, the world, it is hard just to read about it; living it–then, now, and in the future–is almost impossible for me to fathom.

But while living with the aftermath might be hard to imagine, that such a catastrophe could and likely would happen was not. In fact, if there is a theme (beyond the suffering of the Japanese people) that runs through all the Fukushima look-backs, it is the predictability–the mountains of evidence that said Japan’s nuclear plants were vulnerable, and if nothing were done, a disaster (like the one we have today) should be expected.

I touched on this last week in my own anniversary examination, and now I see that Dawn Stover, contributing editor at The Bulletin of the Atomic Scientists, draws a similar comparison:

Although many politicians have characterized 3/11 and 9/11 as bizarre, near-impossible events that could not have been foreseen, in both cases there were clear but unheeded warnings. . . . In the case of 3/11, the nuclear plant’s operators ignored scientific studies showing that the risks of a tsunami had been dramatically underestimated. Japan’s “safety culture,” which asserted that accidents were impossible, prevented regulators from taking a hard look at whether emergency safety systems would function properly in a tsunami-caused station blackout.

Stover goes on to explain many points where the two nightmare narratives run parallel. She notes how while governments often restrict information, stating that they need to guard against mass panic, it is actually the officials who are revealed to be in disarray. By contrast, in both cases, first responders behaved rationally and professionally, putting themselves at great risk in attempts to save others.

In both cases, communication–or, rather, the terrible lack of it–between sectors of government and between officials and responders exacerbated the crisis and put more lives at risk.

And with both 9/11 and 3/11, the public’s trust in government was shaken. And that crisis of trust was made worse by officials obscuring the facts and covering their tracks to save their own reputations.

But perhaps with that last point, it is more my reading my observations into hers than a straight retelling of Stover. Indeed, it is sad to note that Stover concludes her Fukushima think piece with a similar brand of CYA hogwash:

By focusing needed attention on threats to our existence, 3/11 and 9/11 have brought about some positive changes. The nuclear disaster in Japan has alerted nuclear regulators and operators around the world to the vulnerabilities of nuclear power plant cooling systems and will inevitably lead to better standards for safety and siting — and perhaps even lend a new urgency to the problem of spent fuel. Likewise, 9/11 resulted in new security measures and intelligence reforms that have thus far prevented another major terrorist attack in the United States and have created additional safeguards for nuclear materials.

When it comes to post-9/11 “security” and “intelligence reforms,” Stover is clearly out of her depth, and using the Bush-Cheney “no new attacks” fallacy frankly undermines the credibility of the entire essay. But I reference it here because it sets up a more important point.

If only Stover had taken a lesson from her own story. The Fukushima disaster has not alerted nuclear regulators and operators to vulnerabilities–as has been made clear here and in several of the post-Fukushima reports, those vulnerabilities were all well known, and known well in advance of 3/11/11.

But even if this were some great and grand revelation, some signal moment, some clarion call, what in the annals of nuclear power makes Stover or any other commentator think that call will be heard? “Inevitably lead to better standards”–inevitably? We’d all exit laughing if we weren’t running for our lives.

Look no further than the “coincidental” late-Friday, pre-anniversary news dump from the US Nuclear Regulatory Commission.

Late on March 9, 2012, two days before the earthquake and tsunami would be a year in the rear-view mirror, the NRC put on a big splashy show. . . uh, strike that. . . released a weirdly underplayed written announcement that the commission had approved a set of new rules drawing on lessons learned from the Fukushima crisis:

The Nuclear Regulatory Commission ordered major safety changes for U.S. nuclear power plants Friday. . . .

The orders require U.S. nuclear plants to install or improve venting systems to limit core damage in a serious accident and to install sophisticated equipment to monitor water levels in pools of spent nuclear fuel.

The plants also must improve protection of safety equipment installed after the 2001 terrorist attacks and make sure it can handle damage to multiple reactors at the same time.

Awwwrighty then, that sounds good, right? New rules, more safety, responsive to the Japanese disaster at last–but the timing instantly raised questions.

It didn’t take long to discover these were not the rules you were looking for.

First off, these are only some of the recommendations put before the commission by their Near-Term Task Force some ten months ago, and while better monitoring of water levels in spent fuel pools and plans to handle multiple disasters are good ideas, it has been noted that the focus on hardening the vents in Mark I and Mark II boiling water reactors actually misdiagnoses what really went wrong in two of the Fukushima Daiichi reactors.

Also, it should be noted this represents less than half the recommendations in last summer’s report. It also does not mandate a migration of spent fuel from pools to dry casks, an additional precaution not explicitly in the report, but stressed by NRC chief Gregory Jaczko, as well as many industry watchdogs.

But most important–and glaring–of all, the language under which these rules passed could make it that almost none of them are ever enforced.

This is a little technical, so let me turn to one of the few members of Congress that actually spends time worrying about this, Rep. Ed Markey (D MA-7):

While I am encouraged that the Commission supports moving forward with three of the most straightforward and quickly-issued nuclear safety Orders recommended by their own expert staff, I am disappointed that several Commissioners once again have rejected the regulatory justification that they are necessary for the adequate protection of nuclear reactors in this country. . . .

After the terrorist attacks of September 11, 2001, the NRC determined that some nuclear security upgrades were required to be implemented for the “adequate protection” of all U.S. nuclear reactors. This meant that nuclear reactors would not be considered to be sufficiently secure without these new measures, and that an additional cost-benefit “backfit” analysis would not be required to justify their implementation. The “adequate protection” concept is derived from the Atomic Energy Act of 1954, and is reflected in NRC’s “Backfit Rule” which specifies that new regulations for existing nuclear reactors are not required to include this extra cost-benefit “backfit” analysis when the new regulations are “necessary to ensure that the facility provides adequate protection to the health and safety of the public.”

Both the NRC Fukushima Task Force and the NRC staff who reviewed the Task Force report concluded that the new post-Fukushima safety recommendations, including the Orders issued today, were also necessary for the “adequate protection” of existing U.S. nuclear power plants, and that additional cost-benefit analysis should not be required to justify their implementation.

While Chairman Jaczko’s vote re-affirmed his support of all the Near-Term Task Force’s recommendations, including the need to mandate them all on the basis that they are necessary for the adequate protection of all U.S. nuclear power plants, Commissioner Svinicki did not do so for any of the Orders, Commissioner Magwood did not do so for two of the three Orders, and Commissioners Apostolakis and Ostendorff rejected that basis for one of the three. As a result, the Order requiring technologies to monitor conditions in spent nuclear fuel pools during emergencies will proceed using a different regulatory basis. More importantly, the inability of the Commission to unanimously accept its own staff’s recommendations on these most straightforward safety measures presents an ominous signal of the manner in which the more complicated next sets of safety measures will be considered.

In other words, last Friday’s move was regulatory kabuki. By failing to use the strictest language for fuel pools, plant operators will be allowed to delay compliance for years, if not completely excuse themselves from it, based on the argument that the safety upgrade is too costly.

The other two rules are also on shaky ground, as it were. And even if by some miracle, the industry chose not to fight them, and the four uber-pro-nuclear commissioners didn’t throw up additional roadblocks, nothing is required of the nuclear facilities until December 31, 2016.

So, rather than it being a salutary moment, a tribute of sorts to the victims in Japan on the anniversary of their disaster, the announcement by the NRC stands more as an insult. It’s as if the US government is saying, “Sure, there are lessons to be learned here, but the profits of private energy conglomerates are more important than any citizen’s quaint notions of health and safety. ”

As if any more examples were needed, these RINOs (rules in name only) demonstrate again that in America, as in Japan, the government is too close to the nuclear industry it is supposed to police.

And, for the bigger picture, as if any more examples were needed, be it before or after March 11, it really hasn’t been that hard to imagine the unimaginable. When an industry argues it has to forgo a margin of safety because of cost, there’s a good chance it was too dangerous and too expensive to begin with.

You Could Even Say It Glows: NRC Votes to Fast-Track a More Dangerous Nuclear Future

7:00 am in Uncategorized by Gregg Levine

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.

First, the Westinghouse AP1000 reactor design got the big thumbs up:

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.

Second, the earthquake worthiness of the AP1000, itself, has been officially questioned by senior NRC officials and Rep. Ed Markey (D-MA), the Ranking Member of the House committee charged with overseeing nuclear regulation:

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.

Not convinced that economics is the real driving force behind this “innovation?” Take a look at the other action the NRC announced Thursday:

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.”

And it is important to mention that the approval of this accelerated process came over the objections of NRC Chairman Gregory Jaczko–who just last week faced both House and Senate panels questioning his leadership style–but the certification of the AP1000 design did not. In fact, at the same time news of the Jaczko witch hunt was blocking out the sun, the NRC chair was actually working with other commissioners–the ones who sent a letter to the White House saying Jaczko was impossible to work with–to secure the unanimous OK for the new reactor.

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.

NRC Chair Jaczko: Events Like Fukushima Too Rare to Require Immediate Changes

For those that think nothing has changed in United States regulation since the Japanese earthquake and tsunami started the ongoing crisis at the Fukushima Daiichi nuclear facility, think again. The pre-disaster mentality of “What could possibly go wrong?” has been replaced with reassurances that “Stuff like that hardly ever happens!”

At least that is the impression conveyed by the current chairman of the US Nuclear Regulatory Commission, Gregory Jaczko, in a pair of early October interviews. During two NRC-sponsored events, Jaczko fielded questions first from nuclear industry professionals and those considered friendly to the expansion of nuclear power, and then, in a separate session two days later, responded to representatives from public interest groups and other individuals generally seen as opposed to nuclear energy.

While the tone of the questions differed somewhat predictably in the two sessions, Chairman Jaczko’s attitude did not. Jaczko took several opportunities to praise the NRC staff and the processes and protocols used by the commission, repeating in both panels that the primary duty of his agency is ensuring the safety of nuclear facilities in the United States.

Beyond his broad assurances and patient, capable demeanor, however, many of the chairman’s assertions about both the NRC process and the progress being made toward his stated safety goals highlighted notable contradictions and troubling biases inherent in America’s nuclear regulatory regime.

To be fair, the pre-Fukushima outlook was not exactly “What could possibly go wrong?” In terms of the types of accidents and the repercussions of contamination, containment breaches, radioactive releases, meltdowns, melt-throughs, and a host of other undesirable situations, regulators and industry insiders alike were probably quite aware of what could go wrong. But as US nuclear proponents and profiteers strove to convey the impression of an informed industry, they also moved to downplay the threats to public safety and made sure to stress that, when it came to disaster scenarios, they had it covered.
