The Office of Inspector General (IG) of the Department of Energy is raising concerns about the ability of the department to safely store radioactive waste in underground tanks at the Hanford Site until its cleanup mission there is complete. Specifically, the IG said that the tanks, which include 149 single-shell tanks (SST) and 28 double-shell tanks (DST), have deteriorated over time and there may not be enough space in the DSTs to accommodate waste from failed tanks.

The audit report, Tank Waste Management at the Hanford Site (DOE-OIG-20-57), was posted to the IG'S webpage on October 5.

The International Atomic Energy Agency has joined with Malaysia’s Atomic Energy Licensing Board (AELB) to establish a pool of radiation detection equipment available for loan to support nuclear security training and detection capabilities in the Asia-Pacific region, the IAEA announced October 7

This is the first such repository facilitated by the IAEA. The equipment was purchased with Japan’s contribution to the IAEA Nuclear Security Fund.

A team of engineers in Argonne National Laboratory’s Nuclear Science and Engineering Division have designed a microreactor called MiFi-DC that could be factory-produced and installed at highway rest stops across the country to power a proposed fleet of electric trucks. The reactors are described in an article, Could Argonne’s mini nuclear reactor solve the e-truck recharging dilemma? and a video released by Argonne on October 6.

Pairing a liquid metal thermal reactor with a thermal energy storage system, each reactor could fuel an average of 17 trucks a day.

The U.S. Department of Commerce and Rosatom, Russia’s state atomic energy corporation, have signed a final amendment to the Agreement Suspending the Antidumping Investigation on Uranium from the Russian Federation. The amendment extends the 1992 pact through 2040 and reduces U.S. reliance on uranium from Russia during that time period, the DOC announced October 6.

Previously, the agreement was set to expire on December 31 of this year. According to the DOC, the document’s expiration “would have resulted in unchecked imports of Russian uranium, potentially decimating the front-end of the nuclear fuel cycle in the United States.”

The final amendment is unchanged from the draft version, released for public comment on September 11. (For more specifics on the amendment, see our story on the draft here.)

Hopes for the construction of a two-unit nuclear power station in Wales—dashed some three weeks ago when Hitachi Ltd. officially announced its withdrawal from the proposed Wylfa Newydd plant—rose again slightly last week when the United Kingdom’s Planning Inspectorate agreed to delay its decision regarding issuance of a development consent order (DCO) for the project.

The original deadline for the decision had been September 30, but following the receipt of a pair of letters from Horizon Nuclear Power—the Hitachi subsidiary in charge of the project—the inspectorate consented to a December 31 extension.

As if COVID-19 and a rancorous presidential election were not enough, over the next few weeks we will also be dealing with the confirmation of a justice to fill the open seat on the Supreme Court. What does that have to do with the American Nuclear Society and nuclear technology? Well, nothing directly, but there is an interesting connection between the Supreme Court and a notable case on nuclear waste decided by the U.S. Court of Appeals for the District of Columbia Circuit in August 2013.

Savannah River’s integrated mission contract will combine liquid waste work with nuclear materials management.

The Department of Energy’s Office of Environmental Management (EM) has begun accepting bids on a new 10-year, $21-billion contract for the Savannah River Site in South Carolina. EM issued a final request for proposal for the SRS integrated mission completion contract (IMCC) on October 1, posting it to EM’s dedicated SRS IMCC website.

The IMCC would coalesce the work of two current contractors, including Savannah River Remediation, the site’s liquid waste contractor led by Amentum with partners Bechtel National, Jacobs, and BWX Technologies, into a single contract, combining liquid waste work with nuclear materials management.

The deadline for proposals for the site contract is December 1.

A recently published paper on clean energy policy for economic recovery calls for the preservation of the current U.S. nuclear reactor fleet and the deployment of advanced nuclear technologies.

The paper, Energy Transitions: The Framework for Good Jobs in a Low-Carbon Future, was released last week by the Labor Energy Partnership (LEP), formed earlier this year by the Washington, D.C.–based nonprofit Energy Futures Initiative (EFI) and the AFL-CIO. According to a joint press release from the two organizations, the LEP was established to “develop policy solutions for a 21st century energy system that creates and preserves quality jobs while tackling the climate crisis.”

The LEP is jointly chaired by Ernest Moniz, founder and chief executive officer of EFI and former U.S. energy secretary, and Richard Trumka, president of the AFL-CIO.

Of the 10 U.S. power plants that generated the most electricity in 2019, nine were nuclear plants, a recent report from the U.S. Energy Information Administration states.

These 10 facilities produced a combined 230 million megawatt hours of electricity last year, accounting for 5.6 percent of all electricity generation in the United States, according to the report. The report also notes a shift in the makeup of the top plants over the past 10 years, from a mix of nuclear and coal-fired generators in 2010 to nearly all nuclear in 2019.

Coal’s share of U.S. electricity generation dropped from 45 percent in 2010 to 23 percent in 2019, the reports says. Stricter air emission standards and decreased cost competitiveness relative to other generators are given as the key reasons for coal’s decade of decline.

High-energy radiation can be detrimental to electronic equipment, necessitating the use of radiation-hardened and -resistant electronics in nuclear energy, decommissioning, and space exploration. The online newsletter Tech Xplore reports on a radiation-hardened and repairable integrated circuit being fabricated by researchers at Peking University, Shanghai Tech University, and the Chinese Academy of Sciences.

The radiation-immune and repairable circuits developed by the researchers are based on field-effect transistors (FET) that use a semiconducting carbon nanotube transistor as a channel, an ion gel as its gate, and a substrate made of polyimide. According to the article, the FETs have a radiation tolerance of up to 15 Mrad, which is notably higher than the 1 Mrad tolerance of silicon-based transistors. The FETs are also capable of being recovered by annealing at moderate temperatures (100 °C for 10 minutes).

New Jersey–based Public Service Enterprise Group (PSEG) has filed applications to extend zero-emission certificates (ZEC) for its Hope Creek and Salem nuclear power plants, co-located in Hancocks Bridge, N.J. Hope Creek is home to one 1,237-MWe boiling water reactor, while Salem houses two pressurized water reactors, with Unit 1 rated at 1,169-MWe and Unit 2 at 1,181-MWe.

According to an October 1 announcement from PSEG, Hope Creek and Salem deliver more than 90 percent of all of New Jersey’s carbon-free energy and are essential to the state’s ability to achieve its goal of a 100 percent carbon-free energy supply by 2050, as outlined in the state’s Energy Master Plan.

Seven open-access, peer-reviewed papers on the design of SPARC, Commonwealth Fusion Systems’ (CFS) fusion tokamak, written in collaboration with the Massachusetts Institute of Technology’s Plasma Science and Fusion Center, were published on September 29 in a special edition of the Journal of Plasma Physics.

The papers describe a compact fusion device that will achieve net energy where the plasma generates more fusion power than used to start and sustain the process, which is the requirement for a fusion power plant, according to CFS.

The timeline for this planned device sets it apart from other magnetic confinement fusion tokamaks: Construction is to begin in 2021, with the device coming on line in 2025.

CFS expects the device to achieve a burning plasma—a self-sustaining fusion reaction—and become the world’s first net energy (Q>1) fusion system. The newly released papers reflect more than two years of work by CFS and the Plasma Science and Fusion Center to refine their design. According to CFS, the papers apply the same physics rules and simulations used to design ITER, now under construction in France, and predict, based on results from existing experiments, that SPARC will achieve its goal of Q>2. In fact, the papers describe how, under certain parameters, SPARC could achieve a Q ratio of 10 or more.

The Crystal River-3 nuclear power plant

Duke Energy and Accelerated Decommissioning Partners (ADP) on October 1 announced the completion of a transaction to begin decontaminating and dismantling the Crystal River-3 nuclear power plant this year instead of in 2067. ADP, a joint venture of NorthStar Group Services and Orano USA formed in 2017, was chosen by Duke Energy in 2019 to complete the decommissioning of the pressurized water reactor by 2027—nearly 50 years sooner than originally planned.

The Nuclear Regulatory Commission approved the transfer of Crystal River’s operating license from Duke Energy to ADP on April 1, and the Florida Public Service Commission unanimously approved the transaction on August 18. Duke Energy permanently ceased operations at Crystal River-3, in Citrus County, Fla., in 2013, initially placing the reactor in safe storage (SAFSTOR), whereby the decommissioning work would begin in 2067 and end by 2074.

Rosatom, Russia’s state atomic energy corporation, announced last week that the reactor pressure vessel for Unit 1 of Turkey’s Akkuyu plant has been shipped from the Atommash plant in Volgodonsk, Russia. Also, the four steam generators for the reactor have arrived at the Vostochny Cargo Terminal, near the port of Mersin in southern Turkey. Atommash has shipped all the most important large-sized equipment for the primary circuit of the reactor for Akkuyu-1, Rosatom said.

Atommash is a branch of AEM Technologies, which is part of Atomenergomash, the equipment-building division of Rosatom.

This summer, the Department of Energy’s Basic Energy Sciences Advisory Committee (BESAC) completed a report, The Scientific Justification for a U.S. Domestic High-Performance Reactor-Based Research Facility, that recommends the DOE begin preparing to replace the pressure vessel of the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory and to convert the facility to use low-enriched uranium fuel. It also recommends that work begin that could lead to a new research reactor. An article published on the American Institute of Physics website summarizes the report, which was requested by the DOE in 2019.

Within the energy sector, the management of projects and megaprojects has historically focused on the planning and delivery of the construction of infrastructure [1–3]. Therefore, policies are more oriented to support the construction of infrastructure rather than its decommissioning. Globally, however, a number of facilities have reached or will soon reach their end of life and need to be decommissioned.

These facilities span the energy sector, including nuclear power plants, oil and gas rigs, mines, dams, etc., whose decommissioning present unprecedented technical and socioeconomic challenges [4–7]. Moreover, the cost of decommissioning and waste management of this array of infrastructure is estimated to reach hundreds of billions of dollars and, for most of these projects, keeps increasing, with limited cross-sectorial knowledge-transfer to mitigate the spiraling increase of these figures.

Cross-sectorial knowledge-transfer is one way to tackle this matter and improve the planning and delivery of decommissioning projects. The aim of our research has been to build a roadmap that is designed to promote the sharing of good practices between projects both within the same industry and across different industrial sectors, focusing specifically on major decommissioning and waste-management challenges.

To reach this aim, our research leverages on the experience of senior industry practitioners and their involvement in the decommissioning and waste management of infrastructure in different sectors. More specifically, this research addresses the following questions:

To what extent can lessons learned be transferred across industrial sectors?

What are the challenges that hinder successful cross-sectorial knowledge-transfer?

The European Union’s education and training policy must do more to ensure that the nuclear sector has a sufficient number of people with the right skills, according Nuclear: Investing in a Competent Workforce for the Benefit of Society, a new position paper from Foratom. The Brussels-based Foratom is the trade association for the nuclear energy industry in Europe.

Stressing the vital roles that nuclear plays in low-carbon power generation and medical diagnosis and treatment, Foratom warns of a growing skills shortage, stemming in part from the significant portion of the nuclear workforce approaching retirement age.

In addition, the report states that “adapting to digitalization and automatization (which are important skill shifts for the decommissioning sector, as well as for new build) will be a challenge faced by the industry. This will require the reskilling and upskilling of workers, as well as ensuring an adequate transfer of knowledge between generations through apprenticeship schemes, for instance.”

Abbott

In a letter sent to President Trump on September 30, Texas Gov. Greg Abbott expressed his opposition to two proposed consolidated interim storage facilities for spent nuclear fuel that are currently under review by the Nuclear Regulatory Commission. Abbott is opposing Interim Storage Partner’s (ISP) interim storage facility in West Texas and Holtec International’s planned facility in New Mexico, near the Texas border, claiming that the facilities will put U.S. energy security at risk by being sited within the oil-producing region of the Permian Basin.

Abbott also said that he was opposed to increasing the amount of radioactive waste permitted to be disposed of in Texas without state approval. In April 2019, Abbott wrote to the Department of Energy and the NRC expressing his objections to federal actions that could allow Waste Control Specialists (WCS) to accept greater-than-Class C waste at its disposal site in Andrews County, Texas. ISP is a joint venture of WCS and Orano USA.

New Orleans–based Entergy Corporation last week announced a commitment to achieve net-zero carbon emissions by 2050, joining a growing list of major energy companies to make that promise—including Dominion Energy, Duke Energy, Southern Company, Xcel Energy, and Public Service Enterprise Group. And, like those companies, Entergy says that it sees nuclear playing an important role in the realization of that goal.

The House of Representatives on September 29 unanimously passed three bills aimed at strengthening the cybersecurity of the U.S. electric grid and other energy infrastructure. The legislation now moves to the Senate for consideration.
