Outgoing NRC Chmn. Jaczko testified before the House Committee on Oversight and Government Reform last year.
The Chairman of the Nuclear Regulatory Commission, Gregory Jaczko, submitted his resignation Monday morning. Chairman Jaczko, a former aid to Senator Harry Reid (D-NV) and Representative Ed Markey (D-MA) who holds a PhD in particle physics, was originally appointed to the NRC in 2005, and elevated to chairman in 2009. Jaczko said he will relinquish his post upon confirmation of a replacement.
Jaczko’s announcement is hard to separate from pressing questions about the safety of commercial nuclear power in the United States–especially in the context of the ongoing crisis in Japan–the debate over the future of the Yucca Mountain nuclear waste repository, signs of shifting power dynamics in Washington, and, perhaps most importantly, the influence of wealthy and well-connected private industry on public policy.
As has been discussed here before, Greg Jaczko has been at the center of an orchestrated controversy for much of the last year, with nuclear industry lobbyists, Republican members of Congress, and other NRC commissioners pressing for the chairman’s ouster. Representative Darrell Issa (R-CA), head of the House Committee on Oversight and Government Reform, has been an especially dogged critic of Jaczko, holding hours of hearings and serving as the driving force behind two inspector general reports on the allegedly hostile workplace environment at the NRC.
Issa, it must be noted, represents a district that includes the extremely troubled San Onofre Nuclear Generating Station (SONGS). The plant is currently offline as regulators try to determine the root causes of radiation leaks and rapid degradation of copper tubing used to move radioactive steam in and out of the reactors. The Orange County Republican has received copious campaign contributions from the companies that operate and maintain San Onofre.
Issa called hearings (while calling for Jaczko’s head) last year after the four other commissioners made public their letter to the White House complaining about Jaczko’s managerial style. The complaint revolved around a handful of issues that help explain the apparent urgency behind the anti-Jaczko putsch.
First, critics were upset about the way that Jaczko helped end work on the Yucca Mountain nuclear storage site. Yucca had proven problematic for a number of reasons–environmental, economic, security, and social–and had long been the target of Nevada politicians (most notably, Senate Majority Leader Reid), who felt their state had been dealt with unfairly in the original selection process.
But the nuclear industry desperately needs an answer to the problem (crisis, really) of long-term nuclear waste storage, and Yucca Mountain is the only site that has even been started. (It is nowhere near finished.) Without a place to move “spent” fuel and the other dangerous detritus of the process, nuclear power cannot realistically expand the number of rectors in the US, nor can it long continue to maintain and refuel those already in operation.
Readers of this space know that the pace of safety reforms for America’s nuclear facilities, especially in the aftermath of Japan’s Fukushima disaster, has been alarmingly slow. The recalcitrance–if not active hostility–exhibited by the nuclear operators and their government handmaidens borders on the criminal. So, it might sound more than a little bit shocking to hear that the chairman of the Nuclear Regulatory Commission, Gregory Jaczko, is now under attack. . . for trying to implement new safety standards too quickly.
That’s not how House Oversight and Government Reform Committee Chairman Darrell Issa (R-CA) is putting it, of course. In doublespeak that would make Orwell proud, Issa has written to the White House, issued a report, and fallen just shy of calling for Jaczko’s head:
“The current Chairman, through his blatant disregard for the Commission and its core beliefs, is testing this resolve,” the report says. “The NRC has survived thus far but the cracks are forming and all symptoms point to catastrophe.”
The report comes several days after Issa released a mid-October letter from the NRC commissioners to the White House that alleges that Jaczko is causing “serious damage” to the agency that could harm the body’s ability to protect health and safety.
The reality, of course, is that Issa–who has summoned Jaczko and fellow commissioners to appear at hearings this very day–has a vested interest in obstructing new health and safety rules, and the hubbub and hearings he is now orchestrating do not in any way focus on post-Fukushima lessons learned, unless that lesson is that the nuclear industry must engage a full-court press to preserve their privilege and profits in light of a new global awareness of the true cost and real dangers of nuclear power.
Since taking the gavel at Oversight, Issa has used his authority to disrupt government’s regulatory roll in the service of his corporate benefactors.
Uninterrupted electricity is essential for nuclear safety. Without electricity, nuclear power plants are unable to pump cooling water through reactor cores and spent fuel pools to prevent overheating and fuel melting.
Without power, plant operators cannot control reactor activity or remotely monitor spent fuel.
It was the loss of electrical power that led to the partial-meltdown of multiple reactors, significant radiation release and damage to the spent fuel pools at the Fukushima Daiichi plant in Japan after the devastating 9.0 earthquake and tsunami in March.
First, I can’t move on without noting two problems there in the last paragraph.
I don’t know how Feinstein defines it, but I think most of the world has dropped the “partial” from the assessment of the meltdowns at Japan’s Fukushima Daiichi nuclear facility. Maybe DiFi has some secret pictures that show tiny bits of intact cladding floating on top of the blobs of corium now understood to be at the bottom of at least some of the damaged reactors, and so she feels uncomfortable going all the way, but the company that nominally runs the facility and the country that is unlucky enough to serve as its home feel sure enough to call it a meltdown without the modifier, so I think US Senators should, too.
Also, it is now believed that a meltdown in at least one of the reactors started before the tsunami that followed Japan’s March 11 earthquake. In other words, as I reported previously, the earthquake damaged the containment vessel or, more likely, the cooling system before the massive wave knocked out the backup generators and, thus, power to the cooling system. So, the loss of power did not lead to at least some of the meltdown—earthquake damage did.
That is not just an academic nitpick, it goes directly to how Feinstein and the entire US regulatory structure should evaluate the safety of domestic nuclear power plants.
Second: “Uninterrupted electricity is essential for nuclear safety.” Just think about that for a second. Uninterrupted electricity is essential for the safe generation of electricity. It is a logic that seems as vulnerable to reason as nuclear cooling systems are to seismic and tidal events.
But third, I do want to congratulate Senator Feinstein for recognizing and writing the obvious:
The incident [Tuesday’s magnitude 5.8 quake centered in Virginia] was a stark reminder of how vulnerable America’s nuclear power plants are to natural disasters.
I mean that congratulations sincerely. Yes, we didn’t really need a new reminder—Japan’s Fukushima disaster is recent and ongoing—but the Mineral, VA earthquake was another indication that our nuclear plants are vulnerable to natural and manmade disasters at many points. And more American politicians should say just what DiFi said, instead of brushing off Japan’s already extant stark reminder as a “can’t happen here” event, or quickly forgetting Tuesday’s quake because it resulted in “minimal damage and no loss of life” (to use Feinstein’s own rosy words).
Feinstein continues by laying out four “lessons” that Japan and Virginia should teach us. (It is really more like two or three points with repeats, but that’s OK.) The headlines:
First, our country needs a comprehensive, national policy to address the management of spent fuel, the radioactive waste produced while generating electricity by fission.
Second, today’s efforts to protect against seismic and flooding hazards may not be sufficient.
Third, we must improve the redundant safety systems to respond to disasters.
Finally, for spent fuel stored at reactor sites, dry casks are safer and more secure than permanent storage in spent fuel pools.
Both the first and fourth points note that storing spent fuel in pools of circulating water is not a particularly safe, efficient, or cost-effective way of dealing with one of nuclear power generation’s biggest problems. Not only are these pools also dependent on an uninterrupted source of electricity to keep water circulating and levels high enough to keep the rods—now packed in at many times the pools’ original designed capacity—from overheating and melting themselves or cracking the water and triggering hydrogen explosions, the cooling systems for the pools are also vulnerable to seismic events.
Feinstein says that spent rods should be moved to dry casks and eventually to a secure repository, observing that spent fuel in Japan housed in dry casks had no problems after the March 11 quake and flood. Strangely, though, the senator cites the Nuclear Regulatory Commission’s special taskforce report on the aftermath of the Japanese disaster as the inspiration for making this call for dry casks and a national fuel repository—strange because, as both Physicians for Social Responsibility and I noted back when the report was released, the task force pointedly did not make any recommendations for moving spent fuel to dry casks or to off-site repositories.
Feinstein also says she has learned that protections against earthquakes and flooding may not be sufficient. Again, DiFi modifies—there is really no need to say “may” here. From Fukushima Daiichi to the reactors in Virginia known as North Anna 1 and 2, it should now be very clear that nuclear plants are walking a precarious line between “minimal damage” and catastrophic failure.
Let’s look more closely at what happened on Tuesday. A 5.8 earthquake centered 15 miles from the North Anna nuclear power generating facility cut electrical power to the plant. Backup diesel generators kicked in to provide power to the cooling systems, averting the overheating of either the reactor core or the pools of spent fuel. Good news, as far as it goes, but there are several disconcerting caveats.
First, we don’t know if the plant—which is theoretically designed to withstand a quake of a 6.2 magnitude—has actually emerged from Tuesday’s tremor completely unscathed. The reactors are currently being brought to a cold shutdown so that they may be inspected further. Not only must the containment vessels be more closely inspected, the cooling system must be tested for leaks. Some of the pipes and conduits for that system are underground. As reactor expert Paul Gunter has noted, an underground rupture, one that might be leaking radioactive tritium into ground water, is quite possible and needs to be investigated more fully.
(As a caveat to the caveat, I must note that we also need to find a way to verify that the public is being fully informed about any damage and radioactive leaks—not a sure thing in light of both the evolving story of cover-up in Japan and this summer’s expose on collusion between the NRC and the nuclear industry.)
Second, the North Anna plant gets its name from Lake Anna, an artificial lake created to provide a reservoir for the cooling requirements of the nuclear facility. What if the quake had caused the dam that holds the water in Lake Anna to rupture? Beyond the dangerous flooding to well-populated communities downstream, the water level in the reservoir would drop to a point where the nuclear plant’s cooling system would fail. If this were to happen, no amount of redundant power generation would fix the problem. Does this sound farfetched? It is not. Virginia is noteworthy for its lack of attention to its aging infrastructure—in fact, according to the American Society of Civil Engineers’ infrastructure report card [PDF], the condition of Virginia’s dams gets a D-minus.
(It should be noted that the initial inspection of the Lake Anna dam after Tuesday’s quake showed no new damage.)
Third, not all of North Anna’s backup generators worked on Tuesday. Only three of the four came online after power was lost. (Hooray for required redundancy.) What is not clear is what effect this had on the plant’s ability to function normally, or what would have happened if grid power had not been restored as quickly to the facility.
And finally, to simply give a Richter scale number as a sort of assurance of the safety of a nuclear facility is overly simplistic if not downright deceptive. Here’s why:
As noted here today and before, there are many systems that have to survive an earthquake—the reactor containment vessel, its cooling system, the spent fuel pools, their cooling systems, the reactor building, the monitoring equipment, and a plant’s connection to a steady supply of electrical power. In theory, all these systems were evaluated when the plans for a nuclear facility were initially approved. They all should survive a quake of a specified magnitude.
However, all of America’s nuclear facilities were licensed during a time when regulators assessed designs based on what is called Deterministic Seismic Hazard Analysis (DSHA). But, as noted in a May Congressional Research Service report [PDF]:
Since then, Probabilistic Seismic Hazard Analysis (PSHA) has been adopted as a more comprehensive approach in engineering practice. Consequently, the NRC is reassessing the probability of seismic core damage at existing plants.
I am not an expert in plate tectonics, but what I read tells me that you would feel more secure with a PSHA-generated standard—and what I have learned from Fukushima is that I want that standard applied to all the systems needed to safely operate a nuclear power plant. But what this report tells me is that the NRC is only in the midst of some process of reevaluating plants’ seismic vulnerability—a process that was to have begun last year but has moved very slowly (and this is only the evaluation stage)—and that this re-evaluation is of the probability of core damage, which, to my eye, is not the same as an evaluation of every system needed for the reactor and the spent fuel pools to remain safe.
And I am not alone in my worries. Here’s the NRC itself after it looked at North Anna in April (via the Institute for Southern Studies and the Center for Public Integrity):
Specifically, the NRC report notes that portions of water and gaseous suppression systems and hose stations “are not seismically designed.”
The report noted that “potential leakage can occur through penetrations following seismic event.”
There’s also concern about what a major quake would mean for the water-filled pools used to store spent fuel at most U.S. nuclear plants. Bob Alvarez, a senior scholar at the Institute for Policy Studies who recently authored a report on the dangers of spent fuel storage in the United States, addressed the issue in a piece on the IPS blog posted shortly after the quake:
The North Anna reactors are of the Westinghouse Pressurized Water design and went on line in 1979 and 1980 respectively. Since then the reactors have generated approximately 1,200 metric tons of nuclear spent fuel containing about 228,000 curies of highly radioactive materials — among the largest concentrations of radioactivity in the United States.
Alvarez went on to note that almost 40 percent of the radioactivity in North Anna’s spent fuel pools is in the form of cesium-137, a long-lived isotope that presents serious health risks and accumulates in the food chain. He continued:
The spent fuel pools at North Anna contain four to five times more spent fuel than their original designs intended. As in Japan, all U.S. nuclear power plant spent fuel pools do not have steel lined, concrete barriers that cover reactor vessels to prevent the escape of radioactivity. They are not required to have back-up generators to keep used fuel rods cool, if offsite power is lost. Even though they contain these very large amounts of radioactivity, spent reactor fuel pools in the United States are mostly contained in ordinary industrial structures designed to protect them against the elements.
This goes to explaining the confusion I see over whether just parts or the entirety of a nuclear facility is required to meet a specific earthquake safety standard. But what it doesn’t do is imply that a single, plant-wide standard will be used in the future.
As noted when the special task force report came out earlier this summer, the recommendation that the current patchwork of safety rules should be unified and standardized was actually being slow-walked by three of the five NRC commissioners. Finally, one week ago, the commission agreed to give its technical team 45 days to analyze some of the recommendations, but they will be given a full 18 months to analyze the recommendation that the NRC revise its entire regulatory framework in light of lessons learned after the Fukushima disaster.
It should also be noted that there is currently no law that requires the NRC to apply the new, better seismic standards when evaluating requests for license renewals or the building of additional reactors at existing facilities. (There is a bill, languishing in the House, designed to fix this. . . did I mention it was languishing?)
Which brings us back to Senator Feinstein, or, really, her California colleague, Sen. Barbara Boxer (D), who chairs the Committee on Environment and Public Works and has oversight responsibilities over the NRC. While DiFi has written about the lessons of this week’s Virginia quake, Boxer has demanded action on the NRC taskforce report on the lessons learned from Fukushima. At a hearing on August 2, Boxer demanded the NRC pick up the pace on evaluating the recommendations and report back to her by November. With the NRC’s decision on how it will move forward, and the latest in a lengthening string of “wakeup calls” having caused incidents at North Anna and a number of other eastern nuclear facilities, perhaps both of California’s Senators might consider official hearings before then.
It must also be mentioned that while I was writing this post, Japan’s Prime Minister, Naoto Kan, has stepped down. Stories on the resignation concurrently cite his dismal poll numbers from an anti-nuke electorate, and the lack of support from pro-nuclear members of his party. Kan, who had previously hinted at leaving after the Fukushima crisis was brought under control (it seems I correctly predicted he’d be gone well before that), has also signaled that he wanted to wean Japan off nuclear power for electrical generation and move more aggressively toward renewable sources. Both possible reasons for his early exit speak to some form of accountability—one to the public, the other to entrenched nuclear industry masters—and both have probably played some roll. But what matters going forward is to whom the next leader will answer, and what happens with Japanese nuclear facilities will make that very clear.
In the US, we have a less clear choice—no one has proposed a move away from nuclear power (quitethecontrary)—which, alas, probably tells us who calls the shots in our country. But that ugly political reality doesn’t change the physical one—United States nuclear facilities remain vulnerable to numerous seismic and tidal threats. As Diane Feinstein concludes, “We need to learn the lessons we can to assure that next time we are ready—not just lucky.”
News this week out of Japan that workers at the crippled Fukushima Daiichi nuclear plant have detected extremely high levels of radiation in and around reactor 1. The first incident, on August 1, pinned the Geiger counter at 10 sieverts (1000 rem)—yes, that’s as high as the device could measure, so that number is a minimum—and was taken at the base of a ventilation stack. The second reading, the following day, clocked in at five sieverts per hour inside the reactor building.
I have yet to read an explanation for the discovery of the second reading, but the initial, sky-high measurement on Monday has me and many others scratching heads. A thousand rem is not some little ho-hum number. A half-hour of exposure at that level is fatal in a matter of days, I am told. Where did that radiation come from? When did contamination occur? How is it that such a dangerous level could go unreported for what is now over 140 days?
Officials from the Japanese power company, TEPCO, who have been repeatedly criticized for withholding critical information, insist that contamination likely happened in the first few days of the disaster when workers tried to vent hydrogen from the reactor building in a futile attempt to prevent an explosion. Somehow, though, this part of the facility (which, it should be noted, has been extensively mapped for radioactive hotspots over the last several months) was not measured till August.

Focusing on broad, long-term goals while ignoring obvious, near-term problems is order of the day, be it in the Fukushima reactors or deficit-obsessed DC.
I feel like I am saying this every week, but tear yourself away for a minute, if you can, from the daily deficit follies—I promise we’ll get back to them.
As I detailed last week, a study called the Near-Term Task Force Review listed a set of suggestions for ways the US nuclear power industry could improve safety in the wake of the meltdowns and continuing crisis in Japan’s Fukushima reactors. The recommendations were a mixed bag of mostly regulatory tweaks–nothing particularly bad, as far as they go–but obviously missing from the report was any program that would effectively improve the way spent fuel rods are stored.
That sounds glacial, especially given the ongoing Japanese crisis and many US plants of similar design facing the possibility of similar problems, but even this cautious approach to some cautious recommendations was more-or-less opposed by three of the five commissioners. Read the rest of this entry →
While most of creation is still trying to predict if Congress will raise the debt ceiling, and what will happen to the economy if they don’t, I thought I’d spend some quality time with disasters quite present, and in some ways, quite predictable. I am talking about nuclear power in the wake of Japan’s Fukushima disaster.
We should reduce our dependence in a planned and gradual way, and in the future we should aim to get by with no nuclear energy. When we think of the magnitude of the risks involved with nuclear power, the safety measures we previously conceived are inadequate.
Just doesn’t have the same oomph, does it? Kind of missing the gravity or sense of urgency of a head of state declaring an unambiguous move away from nuclear power, no?
Style points aside—I mean, you can hardly expect President Obama to break away from round-the-clock deficit hysteria to address a looming threat that also happens to siphon billions of dollars from federal coffers in the form of subsidies and loan guarantees—the content of the report itself, its findings and recommendations, also leave me feeling a bit underwhelmed.
As noted, the report is long–and it is dense–but as I understand it, the task force recommends that regulators pay more attention to what the report calls “low-likelihood, high-consequence events”. . . you know, like earthquakes and floods that damage nuclear reactors and safety systems.
Hard to argue with that. . . but then the task force also says that the sort of high-consequence disaster that happened in Japan can’t happen in the US—and that is a point that I and many experts and activists would argue against. To put it very briefly, the United States has many reactors past their projected life spans, many similar in design to Fukushima’s, and many built in areas vulnerable to seismic activity, floods and, yes, even tsunamis.
Also recommended, that the government standardize safety regulations and emergency response plans—and make them actual rules as opposed to voluntary industry initiatives (aka “suggestions”)—which is good as far as it goes, but in the wake of a multi-part AP exposé showing how the NRC conspired with the nuclear industry to lower safety standards, I’m thinking that doesn’t go that far.
Perhaps what is most important, however, is what’s missing from the Near-Term Task Force Review. As noted by Physicians for Social Responsibility, the report makes no recommendation for moving spent nuclear fuel from over-packed pools to hardened on-site storage. A striking omission considering that used fuel rods stored in pools inside the Fukushima reactor buildings were and continue to be a serious part of the crisis in Japan.
Also highlighted by PSR, though completely outside the prescribed scope of the investigation, the task force states that there is an “expectation of no significant radiological health effects” from the Fukushima disaster.
No significant radiological health effects. When I first read that, I assumed the NRC review was referring to the United States—an assertion that already strains credulity as far as I’m concerned, but one that can be debated, given the distance and the data (or paucity of data). But, as I read it—uh, re-read it—this “conclusion” is a general one, as in everywhere, as in an expectation of no significant radiological health effects in Japan.
Now, that assertion, without any long-term health screenings or any epidemiological studies, is as worthless as it is irresponsible, but to make such a statement a week after a Japanese report revealed that 45 percent of children in Fukushima Prefecture have thyroids that show evidence of exposure to radiation makes one wonder what the US task force used for data. . . or if they felt the need to use data at all. Also revealed at the end of June, soil samples from the city of Fukushima—an area well outside of the quarantine radius—contained radioactive cesium at levels 1.5 to 4.5 times greater than the legal limit. (Radioactive cesium 137 has a half-life of approximately 30 years and tends to accumulate in plant tissue and fungal spores.)
But wait, there’s more:
Another sample taken from a street ditch — where nuclear fallout often accumulates — registered as much as 931,000 becquerels per sq. meter, surpassing the 555,000 becquerels per sq. meter limit for compulsory resettlement in the 1986 Chernobyl nuclear accident. Samples from the other three locations measured between 326,000 and 384,000 becquerels per sq. meter.
An earlier survey on soil in the city of Fukushima by the science ministry has found 37,000 becquerels of radioactive substances per 1 kg — equivalent to 740,000 becquerels per sq. meter.
That’s Japan. Here in North America, we found out this week that the Environmental Protection Agency was measuring radioactive iodine in rainwater out west at levels 30, 40, and, in one case, 130 times what is considered the safety standard for drinking water. Granted, a drinking water standard is not the same as a rainwater measure (as I understand it, the drinking water standard is based on the chances that consumption of a glass a day for 30 years will result in cancer), but that does not mean that this revelation doesn’t raise many questions.
For instance, what about negative non-cancer health effects? Has rain-borne radiation contaminated reservoirs, wells, or watersheds? What about bioaccumulation, what about the radiation that winds up in and on plants and animals? And what about—and this has been one of my big questions since the early days of this crisis—what about other isotopes, ones with other deleterious health effects, ones with half-lives measured in decades (like Cs-137) as opposed to days (like I-131)? And, of course, since it has been determined that there is no such thing as a “safe” level of radiation exposure, no matter the source, shouldn’t the government do a better job of informing the public of any significant increases?
To that last point, the report on radioactive rainwater, which is from Heart of America Northwest, also revealed that, in many cases, there was a lag time of a week between the radiation readings and the posting of the information on the EPA’s RadNet website. So, even for those that could parse the data on the less-than-lay-friendly site, the news was nowhere close to real-time, and so nowhere close to immediate enough for individuals trying to assess risk and adjust behavior accordingly.
The same report notes that though the EPA says it stepped up rainwater sampling following the start of the nuclear disaster in Japan, several sites (Portland, OR, for example) do not show additional sample dates beyond the standard once per month. That leads one to assume that the EPA was less diligent than they claimed, but could it also be that the EPA collected samples but chose not to post the data? (That’s an honest question—I don’t know if the latter is possible, but it did occur to me.)
By the way, that increase in sampling—it ended on May 3. . . because, of course, the Fukushima crisis is over. . . .
But, of course, the crisis is not over. Beyond the melted cores in several Fukushima reactors—where Japanese response teams are still trying to understand the shape and temperature of fuel and the integrity of the containment vessels—there are the pools of spent fuel rods, still very radioactive, still sitting in reactor buildings without roofs (which were destroyed by hydrogen explosions in the days after the earthquake and tsunami). Those pools are still sending an unknown amount of radiation into the atmosphere, and those pools will remain exposed for months to come (the first attempt to cover one of the reactor buildings is expected in late September).
So, that’s a lot to digest—for me, yes, and maybe for you, too—but at least I am trying to take it all in. Did the NRC task force take in any of this before they issued their report? Did they digest it? Yes or no, I find their assertion of no significant radiological health effects hard to swallow.
The differences in the levels of response—Germany announcing a plan to end its use of nuclear power, and Japan’s PM stating that his country should do the same, versus the United States quietly releasing a wonky report with a set of recommendations for a sustained nuclear future—tells me that the US government will not learn the lessons of the Fukushima disaster, and I find that hard to stomach.
