Trying to test for cracks in nuclear waste containers that have to last for over a million years

Waste from nuclear fuel must be stored for more than a million years/

“Salt can be present in the ambient air and environment anywhere, not just near the ocean. We need to be able to plan for extended long-term storage of spent nuclear fuel at nuclear power plants for the foreseeable future — it’s a national reality,”

Sandia to put nuclear waste storage canisters to the test,   https://www.newswise.com/articles/sandia-to-put-nuclear-waste-storage-canisters-to-the-test, Scientists will explore science of cracks caused by corrosion, 10-Dec-2020 by Sandia National Laboratories    Newswise — ALBUQUERQUE, N.M. — Sandia National Laboratories is outfitting three 22.5-ton, 16.5-feet-long stainless-steel storage canisters with heaters and instrumentation to simulate nuclear waste so researchers can study their durability.

The three canisters, which arrived in mid-November and have never contained any nuclear materials, will be used to study how much salt gathers on canisters over time. Sandia will also study the potential for cracks caused by salt- and stress-induced corrosion with additional canisters that will be delivered during the next stage of the project.

Currently there is not an operating geologic repository in the U.S. for the permanent disposal of spent nuclear fuel. As a result, spent fuel is being stored at commercial nuclear power plants in both storage pools and dry storage canisters. The storage canisters currently holding the spent nuclear fuel were designed to have a useful life of a few decades but will now likely need to be used longer than planned, said Tito Bonano, Sandia’s nuclear energy fuel cycle senior manager.

Data is urgently needed to validate and guide how industry should manage storage canisters for longer than originally anticipated, Bonano said.

“Salt can be present in the ambient air and environment anywhere, not just near the ocean. We need to be able to plan for extended long-term storage of spent nuclear fuel at nuclear power plants for the foreseeable future — it’s a national reality,” he said.

The researchers expect the project could have long-reaching implications for public health and safety, industry practices, regulatory framework and defining future research paths, said Bonano.

The three-year project is funded by the Department of Energy’s Nuclear Energy office. Overall, fifteen never-used, never-irradiated DOE-owned canisters are being distributed for large scale testing to Sandia and two other national laboratories, an industry research institute and an independent storage facility at an existing nuclear power plant.

Waste from nuclear fuel must be stored for more than a million years

Nuclear power plants use uranium pellets inside a metal-cladded tube, called a fuel rod, to power reactors to create the heat needed to make electricity. After the fuel rods can no longer be used in the reactor, they need to be stored onsite until they are taken offsite to another facility and eventually permanently disposed because they will be radioactive for a long time, said Samuel Durbin, a mechanical engineer and Sandia’s canister project lead.

“When fuel is removed from a reactor, it’s very hot, both in temperature and radioactivity” Durbin said. “The utility loads it into a pool for about five years to cool down. After that, the spent fuel can be offloaded into a dry storage canister.”

A storage canister starts as a flat piece of stainless steel that is rolled into a cylinder and then welded where the seams come together. The heat from the welding creates heat-affected zones in the seams of the canister that experience tensile, or pulling, stress. This stress makes these areas around the welds more susceptible to corrosion from salt over time, said Durbin.

Research will test how much salt deposits on canisters over time

Sandia received three canisters Nov. 13. The research team will outfit each of them with 32 electrical heaters to simulate the decay heat, which is heat released as a result of radioactive decay, from the 32 spent fuel assemblies that would typically be stored in this type of canister. No radioactive materials will be used in the testing, Durbin said.

Instruments called thermocouples, which measure temperature, and other sensors for diagnostic testing and surface sampling also will be added, he said.

Once the outfitted canisters have been tested and repacked for transport at Sandia, the team plans to move them to a storage pad at an independent spent fuel storage installation on the West Coast where they will experience the same real-life conditions of in-use canisters. The Sandia team, led by managers Sylvia Saltzstein and Geoff Freeze, Durbin, and chemists/corrosion scientists Charles Bryan and Rebecca Schaller, along with partners from other national laboratories will monitor the test canisters and record surface deposits, especially chloride-bearing salts, for three to more than 10 years, depending on how much the data varies over time.

“Sodium-chloride, or salt, that settles on the surface of spent nuclear-fuel canisters can lead to chloride-induced stress corrosion cracking, and right now there is inadequate data on these surface deposits,” said Durbin.

In real-life storage of nuclear waste, Durbin said the decay heat from the spent fuel creates natural convection around the storage canisters, causing outside air to be drawn over the canister surface. This process helps cool the spent fuel over time. As ambient air is drawn in, salt and other particulates in the air are drawn in as well and can settle on the canister surface. During the test, the electrical heaters installed inside the canisters at Sandia will replicate this decay heat-driven convection without using nuclear materials.

In hot, dry conditions, Durbin said salt deposits alone don’t cause any issues, but over time, as the decay heat decreases and the canister cools, water can condense on the canister surface and a brine can form.

“These conditions can occur nationwide and are seen as precursors to chloride-induced, stress-corrosion cracking. Back when these canisters were being designed, people weren’t thinking about this as an issue because we had a plan for permanent disposal. The current national nuclear waste situation forces canisters to be stored onsite for the foreseeable future, which could be 100 years or longer, so stress corrosion cracking becomes more of a concern,” Durbin said.

In addition to the long-term heating and surface deposition test, Sandia will use up to another three canisters for laboratory-based tests to conduct fundamental research on cracking caused by salt and stress, especially on the welded seams and intersections of the canisters. Researchers will measure the effectiveness of commercially available crack repair and mitigation coatings.

To test these seams, the team will cut the canisters into small segments and test pieces with and without welded seams to study the pre-cursor conditions for salt and stress to cause the corrosion that leads to cracks, he said.

Good Biden-Kim Relationship Necessary to Avoid a Nuclear Crisis 

Good Biden-Kim Relationship Necessary to Avoid a Nuclear Crisis   Council  on Foreign Relations,  by Guest Blogger for Asia Unbound,  December 4, 2020   The incoming Biden administration will face a nuclear catastrophe unless it can build good relations with North Korea. The U.S. President-Elect can begin by sending the right signals to North Korean leader Kim Jong-un.

Because North Korea has nuclear weapons, the Biden administration cannot unilaterally impose terms on Pyongyang. Refusal to even talk with Pyongyang until it takes steps to denuclearize is a foolish and dangerous approach. Such an approach will likely inflame tensions and return Washington to a tense nuclear standoff with Pyongyang that poses a risk of miscalculation and accidental escalation into a nuclear war. Biden may be under pressure to be “tough” on North Korea to differentiate himself from Trump’s alleged cozy relationship with the North Korean dictator. However, a hostile stance toward Pyongyang will only make North Korea feel more insecure and drive Kim to pursue further nuclear development to ensure his regime’s survival.
Washington must recognize that Pyongyang has no incentive to denuclearize if the regime finds in nuclear weapons a guarantor of its survival and prestige. …………. https://www.cfr.org/blog/good-biden-kim-relationship-necessary-avoid-nuclear-crisis

President-elect Joe Biden – in the grip of the “new nuclear” industry

Biden, once a critic, may boost nuclear power, Peter Behr, E&E News reporter , December 3, 2020 When mismanagement of a nuclear plant on the Lower Delaware River forced an emergency shutdown in 1994, harsh criticism came from a junior U.S. senator whose state lay opposite the Salem, N.J., plant 3 miles away.”For more than a decade, I have sought expanded oversight, enforcement and sanctions to make the Salem facility operate according to the law,” then-Sen. Joe Biden (D-Del.) said, accusing the operator and the Nuclear Regulatory Commission of turning a blind eye to serious, repeated safety issues, including dangerously degraded reactor equipment.

Fast-forward a quarter-century, and now it is President-elect Biden who has included proposals for a new generation of nuclear reactors in his clean energy platform, parting ways with “no-nuke” progressives further to his left.

It isn’t clear how hard Biden will fight in the next few years to support the possible development of a fleet of still-experimental, billion-dollar reactors that wouldn’t come online until at least the 2030s.

A second issue centers on the 95 operating U.S. reactors, some of which may close prematurely because they are losing money, plant owners warn. Getting public support to hold on to the plants’ zero-carbon electricity has been an issue for state governors, but not the White House, so far.

In the 2020 presidential campaign, Biden focused his support for nuclear power on new designs……

“Joe Biden was the first Democratic presidential candidate who’s ever actively talked about advanced nuclear power” as part of the campaign platform, said Jeff Navin, acting chief of staff at the Department of Energy in President Obama’s first term. Navin heads governmental affairs and public policy for TerraPower LLC in Bellevue, Wash., which won an $80 million DOE contract in October to further its novel reactor design.

Navin said he does not think that Vice President-elect Kamala Harris’ reservations about nuclear power as a senator will turn into opposition as Biden’s No. 2. Harris, for example, had opposed the 2018 Nuclear Energy Innovation and Modernization Act — co-sponsored by Sen. Cory Booker (D-N.J.), her 2019 opponent in the Democratic presidential primary — citing reactor safety and nuclear waste disposal concerns………

“Things we’ve seen out of the Biden campaign and the transition team are very promising for a continuation and even acceleration of programs and policies that will support nuclear energy,” said John Kotek, policy development vice president for the Nuclear Energy Institute, the industry’s chief lobbying organization. Kotek was assistant DOE secretary for nuclear energy in the Obama administration. ………

But Biden will hear from environmental policy advocates and nuclear power opponents protesting that the NRC has gone too far to streamline and reduce costs of safety oversight on old reactors as well as safety reviews of new reactor designs.

“The Biden administration will have to turn first to regulatory issues and repair the damage that’s been done at the NRC over the past four years” under President Trump, said Matthew McKinzie, director of the nuclear, climate and clean energy program at the Natural Resources Defense Council.

There are still too many critical questions about new reactor designs to justify writing them into clean energy plans, McKinzie said. “We are very far from an understanding of whether they could ever be commercialized,” he said……..

Transition choices

To head his transition team on energy, Biden chose one of the top technology experts in the Obama administration, Arun Majumdar, founding director of the Advanced Research Projects Agency-Energy (ARPA-E), which funds experimental energy technologies. Majumdar now directs a Stanford University energy institute (Energywire, Nov. 19).

Others on the Biden-Harris transition team bring specific expertise on nuclear issues, including Rachel Slaybaugh, a nuclear engineering professor at the University of California, Berkeley, and a senior technical adviser at ARPA-E……. https://www.eenews.net/stories/1063719675

Biden’s team includes top posts linked to corporations and military contractors

Biden Aides’ Ties to Consulting and Investment Firms Pose Ethics Test
Some of the president-elect’s choices for top posts have done work for undisclosed corporate clients and aided a fund that invests in government contractors.
NYT,  By Eric Lipton and Kenneth P. Vogel,  Dec. 1, 2020

WASHINGTON — One firm helps companies navigate global risks and the political and procedural ins and outs of Washington. The other is an investment fund with a particular interest in military contractors.

But the consulting firm, WestExec Advisors, and the investment fund, Pine Island Capital Partners, call themselves strategic partners and have featured an overlapping roster of politically connected officials — including some of the most prominent names on President-elect Joseph R. Biden Jr.’s team and others under consideration for high-ranking posts.

Now the Biden team’s links to these entities are presenting the incoming administration with its first test of transparency and ethics.

The two firms are examples of how former officials leverage their expertise, connections and access on behalf of corporations and other interests, without in some cases disclosing details about their work, including the names of the clients or what they are paid.

And when those officials cycle back into government positions, as Democrats affiliated with WestExec and Pine Island are now, they bring with them questions about whether they might favor or give special access to the companies they had worked with in the private sector. Those questions do not go away, ethics experts say, just because the officials cut their ties to their firms and clients, as the Biden transition team says its nominees will do.

WestExec’s founders include Antony J. Blinken, Mr. Biden’s choice to be his secretary of state, and Michèle A. Flournoy, one of the leading candidates to be his defense secretary. Among others to come out of WestExec are Avril Haines, Mr. Biden’s pick to be director of national intelligence; Christina Killingsworth, who is helping the president-elect organize his White House budget office; Ely Ratner, who is helping organize the Biden transition at the Pentagon; and Jennifer Psaki, an adviser on Mr. Biden’s transition team.

WestExec did not respond when asked for a list of its clients. But according to people familiar with the arrangement, they include Shield AI, a San Diego-based company that makes surveillance drones and signed a contract worth as much as $7.2 million with the Air Force this year to deliver artificial intelligence tools to help drones operate in combat missions.

At the same time, Mr. Blinken and Ms. Flournoy have served as advisers to Pine Island Capital, which this month raised $218 million for a new fund to finance investments in military and aerospace companies, among other targets.

The team recruited by Pine Island Capital Partners — which is led by John Thain, the chief executive of Merrill Lynch at the time of its collapse in 2008 during the recession and sale to Bank of America — was chosen based on its members’ “access, network and expertise” to help the company “take advantage of the current and future opportunities present in the aerospace, defense and government services industries,” including artificial intelligence, according to a Securities and Exchange Commission filing in September describing the new fund, Pine Island Acquisition Corporation.

Pine Island Capital has been on something of a buying spree this year, purchasing the weapons system parts manufacturer Precinmac and a company until recently known as Meggitt Training Systems and now known as InVeris, which sells computer-simulated weapons training systems to the Pentagon and law enforcement agencies.

Another person listed as a member of the Pine Island team is Lloyd J. Austin III, a retired Army general who is also under consideration for defense secretary, according to a person familiar with the selection process……..

Mr. Biden’s team has faced pressure from the left and government watchdogs to outline steps to minimize the sort of corporate influence and conflicts of interest that marked President Trump’s tenure from the start.

These groups worry not only that Mr. Biden’s aides could shape government policies in ways that could benefit companies that paid their firms, but also that the firms could become magnets for access seekers in the Biden administration……….. https://www.nytimes.com/2020/11/28/us/politics/biden-westexec.html?smid=tw-share

Shortfalls in planning mean that the USA Waste Isolation Pilot Plant could become full

Weather Channel 2nd Dec 2020, The only underground nuclear waste dump in the United States is suffering from shortfalls in planning and staffing that could lead to disruptions at the facility, according to a new report from the Government Accountability Office. The report published last month indicated that the Waste Isolation Pilot Plant near Carlsbad, New Mexico, could become full if the amount of waste shipped to the facility keeps expanding or if a new way of measuring waste is rejected in a pending court challenge, according to the Associated
Press.

The plant, known as the WIPP, was built in the 1980s for the disposal of defense-related nuclear waste, including clothing, tools, rags,
debris, soil and other items contaminated with radioactive elements, according to a fact sheet from the facility. The WIPP’s disposal rooms were carved out of ancient salt beds 2,150 feet below ground.
