Waste Confidence – This Chat is Closed
My name is Keith McConnell and I am the Director of the Waste Confidence Directorate. Unfortunately, Andy Imboden, who was scheduled to moderate this Chat, could not be here today, so I will be answering your questions.
I have been at the NRC since 1986, bringing my background and expertise as a geologist to various projects, including waste management, decommissioning and uranium recovery, as well as other positions. I have also served three NRC chairmen and in the Office of General Counsel.
I have a Bachelor’s degree in Geology from Clemson, a Master’s in Geological Sciences from Virginia Tech and a Ph.D. in Geological Sciences from the University of South Carolina.
“Waste Confidence” refers to the Commission’s determination on the environmental impacts of storing spent nuclear fuel from the time a reactor’s license expires until final disposal of the fuel. This is an area with many political, legal, and technical issues.
The Directorate is currently developing a generic environmental impact statement to support an updated Waste Confidence rule. More information about Waste Confidence, public involvement opportunities, and links to relevant documents is available on the NRC’s Waste Confidence website. You can also check out this video on our NRC YouTube channel.
We’ve kept you up to date on our progress through several blog posts and regular teleconferences. Currently, the Commissioners are evaluating the draft generic environmental impact statement and proposed rule . We hope – with their approval – to publish them soon for a 75-day public comment period. We are also planning 10 public meetings to receive public comments – two here at NRC headquarters and 8 around the country. I hope we can discuss how you can participate in this extensive public outreach effort during this NRC Chat.
As this will be an informal discussion, anything you submit in the Chat will not be considered as an official comment on the rule or the generic environmental impact statement. Be sure to submit your comments once the public comment period is announced.
I look forward to your questions about the Waste Confidence process, status and upcoming opportunities for public participation.

The GEIS does not appear to have evaluated the level of degradation to the spent fuel pool concrete from direct accumulative radiation expsoure. Was that analysis done, and is there a report on the results?
Moderator 2:09 pm on July 23, 2013 Permalink
You’re correct, it’s not explicitly considered in the GEIS. It would be part of the aging management process and part of license renewal on a site specific basis. It is an issue dealt with outside of waste confidence.
KM
Dirk 2:14 pm on July 23, 2013 Permalink
The existing data set used for such evaluations suggests that aggregate gamma doses exceeding 10^10 rad lead to progressive degradation of concrete. The predicted dose to many reactor and basin locations appear to exceed this after the 40 year design life. How is relegating this to an aging program adequate, when this is a generic issue that all such locations will face?
Also, this data set (four data points) is for concrete that was continuously wetted. The lined spent fuel pools more likely act as dry concrete. There is an additional limited data set of perhaps a dozen data points from the Oak Ridge Shield Reactor and one additional data point from the Temekin PWR, which suggest at least that the level at which degradation begins is as much as 2,000 times lower in aggregate dose, with severe damage occurring withing the range of dose expected in the normal operational life of the reactors. Would this not be most appropriately analyzed as an existing condition in the GEIS?

Please feel free to submit your comments on concrete degredation when the agency publishes its proposed Waste Confidence rule later this year.

In advance of that, I am looking for any information the NRC may have on the degradation of concrete from aggregate expsoure to high radiation doses (both wet and dry) to be able to make meaningful comment.
I am also interested in any report on what the aggregate doses may be for represetnative or bounding cases for spetn fuel pools. Does such information exist? Is it avaialble? How might I locate it?

This information may also be important for analyzing the dose to concrete used in dry cask storage, and hence the relative risk comparison between pool and dry storage.
Moderator 2:01 pm on July 23, 2013 Permalink
Here’s a question we received via e-mail:
Grace Adams: The question I want to submit in advance of the CHAT is:
Since US Navy has the world’s best safety record on nuclear power and as part of our national government is working for all citizens of the United States of America, I feel we can trust US Navy more than any for profit corporation which by definition works only for its stockholders. I believe that if we ask US Navy to figure out what is the safest and what is the most cost-effective way of dealing with all the spent fuel rods from our civilian nuclear power industry?, then US Navy can figure out both what is the safest way and what is the most cost-effective way to deal with all our nuclear wastes. If I am not mistaken, we also have a problem with some plutonium left over from our nuclear weapons program. US Navy can probably also figure out what to do about that. Further, I believe that if asked US Navy can also do whatever they figure out for us is both safest and most cost/effective. So PLEASE, can we just dump the whole problem in US Navy’s lap and trust that they will be willing and able to both decide and do whatever is the safest and most cost/effective plan of action for dealing with nuclear waste?
Please at least ask US Navy their opinion on how to most safely and most cost-effectively to deal with radioactive wastes. Since they have the world’s best safety record on nuclear power and are part of our national government working for the benefit of all our citizens, I trust them, both to decide how to manage radioactive wastes and if they are willing, to execute whatever plan they recommend.
Response: Thank you for your question. I noticed that you raised concerns about radioactive waste from nuclear power plants as well as from nuclear weapons programs. I will respond to your question as it relates to nuclear power plants, but because wastes from the nuclear weapons program are not under the NRC’s authority and are not at issue in this rulemaking, I cannot address them here.
That said, the current policy for disposing of spent fuel from commercial nuclear power reactors was established by Congress in the Nuclear Waste Policy Act of 1982 (as amended). The Nuclear Waste Policy Act assigned specific duties to several agencies of the federal government with regard to spent-fuel disposal. It designated the Department of Energy to locate, build, operate, and close a repository for spent fuel and for high-level nuclear waste. It also assigned to NRC the responsibility to establish regulations governing the construction, operation, and closure of the repository, consistent with environmental standards established by the U.S. Environmental Protection Agency. This means, among other things, that for-profit corporations are not responsible for ultimate disposal of spent fuel. Any changes to this current policy—such as designating the U.S. Navy as responsible for disposing of spent fuel—would have to be approved by Congress.

Thanks for organizing this chat
Here is a question that I’d like to see addressed —
You mentioned in your announcement that the earlier NRC determination, now struck down, was that “environmental impacts of storing spent nuclear fuel after the end of a nuclear power plant’s license are not significant.” Was that determination based on the assumption that there would be no radiological releases due to accidents, attacks, or other unplanned failures to contain radionuclides? If so, what were the risk analysis basis and legal basis for that assumption? Most importantly for purposes of this question, will such potential releases be considered within the scope of the new drafts of the Waste Confidence rule and the new generic EIS?
Thanks for considering this question, and I look forward to the chat,
Moderator 2:04 pm on July 23, 2013 Permalink
In the 2010 update to the Waste Confidence Rule, the finding of no significant impact was based, in part, on consideration of the risk of environmental impacts resulting from postulated accidents and successful terrorist attacks. While the consequences of such events can be large, the probability of such events is very low, which makes the risk low. Postulated accidents and terrorism remain in scope and will be addressed in the draft Generic Environmental Impact Statement and proposed rule.
KM
Ace Hoffman 2:23 pm on July 23, 2013 Permalink
“postulated accidents and successful terrorist attacks” leaves a lot of room for inadequate protection against accidents the NRC “never saw coming” or terrorist attacks by people who think like terrorists, instead of like bureaucrats. I have no idea how you can possibly believe you are expert enough in geopolitical strategy, psychology, opportunity and attitude to know if terrorist attacks are “low probability.” We lost three soldiers and an interpreter to a suicide bomber on a donkey today in Afghanistan. Why did they use a donkey? Because they figured it would work. What will they think of next? I’ll wager a terrorist attack against our spent fuel is NOT a “low probability” event but rather, an absolute certainty. Under such conditions, what is the proper procedure and how much confidence should we have while waiting for those procedures to be carried out?
Moderator 2:34 pm on July 23, 2013 Permalink
The Waste Confidence rulemaking is generically dealing with the environmental impacts that could result from terrorist attacks. The NRC interfaces with other agencies to determine the threat, and uses that information as the basis for considering the likelihood of a terrorist attack.

Mr McConnell, will the NRC abide by the regulations established by the US EPA for a nuclear waste dump?
Moderator 2:10 pm on July 23, 2013 Permalink
A geologic repository is outside of the scope of Waste Confidence, which deals with continued storage of spent fuel between the end of the operating life of a reactor and disposal.
KM
Louis Zeller 2:14 pm on July 23, 2013 Permalink
Even with onsite storage the only consideration, EPA and state regulations still apply. So, would NRC use its resources, legal and otherwise, to support state and federal environmental rules?
Moderator 2:19 pm on July 23, 2013 Permalink
Sorry, your question continues to be outside of our scope. We’re not going to speculate about site specific licensing proceedings.
KM
Louis Zeller 2:23 pm on July 23, 2013 Permalink
Are you saying that both the national nuclear waste repository and the 67 waste sites at nuclear power plants are outside of the scope of the WCD?
Moderator 2:29 pm on July 23, 2013 Permalink
No. We’re saying that disposal is outside the scope. Inside the scope is the continued storage of the spent fuel during the time between the end of the reactor’s operating license and when the fuel is removed for disposal. I hope that clarifies the matter.
KM
Ernest Martinson 2:32 pm on July 23, 2013 Permalink
Does that include storage as de facto disposal due to lack of a disposal site?
Moderator 2:40 pm on July 23, 2013 Permalink
GEIS considers a scenario where spent fuel will need to be stored indefinitely.
KM
Louis Zeller 2:11 pm on July 23, 2013 Permalink
…and further, if the EPA regulations were to be challenged, for example by licensees or industry groups, would NRC use its legal resources to support the stricter regulations promulgated by the EPA, or not?
Moderator 2:17 pm on July 23, 2013 Permalink
Your question is about disposal in a geologic repository, so that’s outside the scope of what we do here in terms of the Waste Confidence rulemaking.
KM
Stephanie Cooke 2:06 pm on July 23, 2013 Permalink
Through the process of reassessing the waste confidence rule is the NRC re-examing the question of whether dry cask storage might be a safer option than spent fuel pools. What is being done to address the issue of crowded spent fuel pools? Stephanie Cooke, Editor, Nuclear Intelligence Weekly
Moderator 2:12 pm on July 23, 2013 Permalink
Waste confidence is looking at the current system in place for storage of spent fuel, including both wet and dry storage. Other parts of the NRC are evaluating expediting transfer of spent fuel to dry casks.
KM
Bill Kinsella 2:08 pm on July 23, 2013 Permalink
I’m glad to hear that accidents and terrorist attacks remain in scope. I presume natural disasters as well–is that correct? Accordingly, what lessons learned from Fukushima will be incorporated into the risk analysis–especially regarding “black swan” events?
Moderator 2:15 pm on July 23, 2013 Permalink
Yes, natural disasters are part of the waste confidence scope. Lessons learned from Fukushima are being incorporated into site-specific licensing actions. We’re aware of those actions and incorporating the information to the extent that it relates to the continued storage of spent fuel.

Possible sites for waste storage (interim or otherwise) include Nevada, Washington, South Carolina, Illinois, and Idaho.
Can you please explain these discrepancies? Why hold public meetings in communities not affected by waste while avoiding those with the most to gain from the public involvement process?
Thank you for you considered answer.
Moderator 2:25 pm on July 23, 2013 Permalink
Your question seems to relate to centralized interim storage as described by the Blue Ribbon Commission. For the purposes of the Waste Confidence rule, we don’t assume the existence of any particular interim storage site.
As to our upcoming meetings — the way we chose the locations of the public meetings was by considering the public comments we got on the issue during scoping, our experience with past meetings on other generic environmental impact statements and consideration of where people lived who expressed the most interest in the issue. It really is a national issue, so we tried to spread the meetings throughout the country. Also, two of the meetings will be nationally web cast so anyone can participate.

I understand that 3 timeframes were analyzed for spent fuel storage, 60 years, 160 years and indefinite. When is the first license scheduled to expire on an existing (relicensed) operating nuclear plant in the U.S.? Would safe storage be 60 years after that or 60 years after the spent fuel is removed from the pool and put into dry casks?
Thank you.
Moderator 2:37 pm on July 23, 2013 Permalink
The first plant to reach the beginning of the short-term time frame in the GEIS is Dresden Unit 1. Its operating license expired in 1996. The 60 year time frame starts when the operating license expires.
KM
Ace Hoffman 2:43 pm on July 23, 2013 Permalink
Wouldn’t it make more sense for the storage license time frame to start when the first fuel is placed in dry casks? What is the reason for it being the cessation of waste production (ie, “operation”?) which could be decades later, with lots of degradation in the interim?
Moderator 2:54 pm on July 23, 2013 Permalink
The environmental impacts of storage in dry casks, during operation, is considered in the site-specific licensing for that facility. Waste confidence looks at the environmental impacts of storage beyond that time. Also, please be sure to take advantage of the upcoming comment period.

Many of your replies take the form of “that’s outside the scope…”. How was the scope of Waste Confidence rulemaking established? What is the relationship between the rulemaking and the EIS? If the original rule has been thrown out by the court, then wouldn’t’ there be a need to redo the scoping process as well? Was that done?
Moderator 2:45 pm on July 23, 2013 Permalink

What IS in the scope of Waste Confidence?
In relation to current and future storage. What levels of confidence are you requiring?
Moderator 2:43 pm on July 23, 2013 Permalink
The scope is the impact on the environment of storage of spent fuel. To be clear, that means spent fuel that remains in storage after the operating life of a nuclear power plant. It does not look at permanent disposal, such as what was anticipated at Yucca Mountain.
KM
Erica Gray 2:36 pm on July 23, 2013 Permalink
I left a post prior to chat session.
The idea of interim storage/ shipping spent rule to temporary sites should be abandoned. It is not a solution to the problem and created more risks.
I would like to know why the NRC has been allowing the industry/utitlity to drag it’s feet on removing the spent fuel from over crowded pools and into dry casks storage on site?
Lessons learned from Fukushima proves the crowded pools pose a great danger.,
A Dominion rep stated they couldn’t even get but so many dry casks a year….why is that ? Costs, or availability?
Erica Gray 2:43 pm on July 23, 2013 Permalink
that should be “would create more risks”.
I wanted to add that Dominion improperly stored spent fuel last year at North Anna…the heat exceeded the casks design. Dominion ended up getting an exemption….said it would cost too much to redo and expose people to radiation.
I have no confidence in radioactive waste being transported, specially if they can’t even get that right.

Our Fukushima lessons-learned folks are considering expedited transfer of spent fuel from pools to dry cask storage. That consideration is currently underway.
KM
Yamabara Shinzo 2:36 pm on July 23, 2013 Permalink
Thank you for holding this chat session.
My other question relates to Waste Confidence as it is affected by congress.
We are discussing on site storage, possibly even HOSS, because the federal government has not yet come up with a solution to long term storage.
If congress fails in the long term to come up with a centralized solution for waste storage, is on site storage a viable alternative in perpetuum? Can the industry continue to grow and thrive with a model of on site storage even with the knowledge that a permanent centralized site will never materialize?
Moderator 2:49 pm on July 23, 2013 Permalink
The national policy still is disposal in a geologic respository. However, in response to the court’s decision, we in waste confidence have considered the environmental impacts for indefinite storage.
KM
Bill Kinsella 2:52 pm on July 23, 2013 Permalink
How do you do RA calculations for indefinite storage? It would seem that “indefinite” can include “forever” or “a very lomng time.” On such time scales, high-consequence, low probability risks become more likely–eventually they become high probability. Basic math. How is this addressed in your RA?

What are the criteria for determining an adequate level if confidence?
Moderator 2:52 pm on July 23, 2013 Permalink
We considered the experience of storing spent fuel, and that, along with consideration of the environmental impacts that result from continued storage is the basis for the waste confidence rule.
KM
Moderator 2:44 pm on July 23, 2013 Permalink
Some of the radioactive elements in spent fuel remain radioactive for many thousands of years. So plans for storage and ultimate disposal of spent fuel focus on continued safety and security of the material. The radioactivity level of spent fuel does drop over time as the more-radioactive (and thus shorter-lived) elements decay.
KM
Ace Hoffman 2:52 pm on July 23, 2013 Permalink
The greatest harm would occur if the fission products in the fuel are released early on — by several orders of magnitude over just a few decades later. Therefore the most important time to secure the fuel properly is now, not at some later date in some “ultimate” repository, when it will be 1% or one tenth of 1% of the danger it is now: Still frightfully dangerous and in need of isolation, but damage to DNA now will cause lasting effects, so again, now is the most important time to properly protect the fuel. Ceasing operation of all nuclear power plants would be a good first step. Or is that not being considered by the NRC yet as a viable and reasonable option? When was the last time (if ever) the NRC evaluated the full scope of problems with nuclear power versus other energy choices? This is within scope of this chat because we are discussing the safest way to handle spent fuel from shut-down to permanent repository. The safest way to handle it — the ONLY safe way — is not to make any more of it and thus reduce the ‘shorter-lived elements to nothing.
Stephanie Cooke 2:47 pm on July 23, 2013 Permalink
Could you give us a tad bit more to go on vis the specifics of this proposed rule. Do these safety rules address overcrowding in a more detailed way than existing regs? Do they require dry storage after a certain period of time? Do they set out rules for security at plants particularly once a reactor has been decommissioned?
Moderator 2:57 pm on July 23, 2013 Permalink
The current version of the waste confidence doesn’t have a safety part to its rule, just the environmental impacts of the storage. The rule is now before the Commission. You can see the Commission review draft on the Waste Confidence Decision section of the web site at http://www.nrc.gov.
KM
Kathryn Lewis 2:48 pm on July 23, 2013 Permalink
Also in reference to the 3 timeframes, I believe the NRC envisions/recommends that in the case of 160 yrs or indefinite storage that the ISFSI and “dry transfer system” (casks?) be replaced every 100 years. Would these activities also be overseen by the NRC with regard to safety? If so, would it require that new regulations specific to this process be developed?
Thank you.
Moderator 2:59 pm on July 23, 2013 Permalink
The assumption is the NRC would have regulatory oversight over the activities of the dry transfer system.

Congress declared, under the Nuclear Waste Policy Act of 1982 (as amended), that it is the policy of the United States to rely on a deep, geologic repository at Yucca Mountain to dispose of the nation’s spent nuclear fuel. The NRC is required to perform licensing reviews and activities related to an application for such a facility. In 2010, the Department of Energy moved to withdraw its application for Yucca Mountain. The matter is now before the U.S. Court of Appeals for the District of Columbia Circuit.
