The Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) has updated its list of who should be considered an indispensable part of the nation’s critical infrastructure workforce during the COVID-19 pandemic, adding more specificity for the nuclear sector.

The update was released on March 28, one week after CISA issued Guidance on the Essential Critical Infrastructure Workforce: Ensuring Community and National Resilience in COVID-19 Response, Version 1.0. In that initial document, the agency made only three explicit references to nuclear employees, identifying workers “needed for safe and secure operations at nuclear generation,” as well as those involved in critical manufacturing or hazardous materials work at nuclear facilities.

The Department of Energy’s Office of Environmental Management (EM) has issued an outline of planned accomplishments over the next decade to capitalize on progress it has made in cleaning up former government weapons and research sites over its first 30 years. The release of the 66-page report, A Time of Transition and Transformation: EM Vision 2020-2030, was announced on March 9 by William “Ike” White, DOE senior advisor for environmental management, during the 2020 Waste Management Conference in Phoenix, Ariz.

Ongoing efforts to deal with the coronavirus pandemic could hinder progress at the reactor construction project currently under way at the Vogtle nuclear plant near Waynesboro, Ga., according to a Southern Company report filed on April 1 with the Securities and Exchange Commission.

The Nuclear Regulatory Commission on March 24 relicensed the only uranium conversion plant in the United States, Honeywell International’s Metropolis Works.

Metropolis Works can now operate until March 24, 2060, potentially logging operations for over a century. Built in 1958 to produce uranium hexafluoride (UF6) for the U.S. government, Metropolis Works began selling UF6 on the commercial market in 1968.

Southern Company subsidiary Georgia Power announced on March 27 that the Unit 4 vessel top head has been placed, following the completion of major lifts inside the containment vessel. The milestone comes approximately one year after Unit 3’s containment vessel top was lifted into place.

On March 28, the Nuclear Regulatory Commission informed the industry via letter that nuclear plant operators can apply for 60-day exemptions from the agency’s work-hour control regulations—found in 10 CFR 26.205—to address workforce issues arising from the COVID-19 public health emergency. The pandemic has compelled some operators to limit the number of employees physically present at plants to “essential” personnel.

The International Atomic Energy Agency plans to provide diagnostic kits, equipment, and training in nuclear-­derived detection techniques to countries asking for assistance in tackling the worldwide spread of the coronavirus that has caused the COVID-­19 pandemic. IAEA Director General Rafael Mariano Grossi announced the plans on March 9 during his first formal address to the IAEA’s Board of Governors (see previous story).

“The IAEA is not a specialized health agency and has no role in controlling the disease,” Grossi said, “but we do have expertise and experience that help in detecting outbreaks of certain viral diseases and in diagnosing them.”

According to a statement from the China National Nuclear Corporation (CNNC), a key hot performance test was conducted on Unit 5 of the Fuqing nuclear power plant in Fuzhou, in East China’s Fujian Province, on March 2. The CNNC said it is the world’s first nuclear power project using Hualong One technology, also known as HPR 1000, a third-­generation reactor design developed by China. A total of five nuclear power units adopting HPR 1000 technology are under construction by CNNC in China and other countries.

Rafael Mariano Grossi, the International Atomic Energy Agency’s director general, called on Iran on March 9 to cooperate immediately and fully with the IAEA and to provide prompt access to locations that it has refused to let agency inspectors visit. “The agency has identified a number of questions related to possible undeclared nuclear material and nuclear-related activities at three locations that have not been declared by Iran,” Grossi said in his first address to the IAEA’s Board of Governors since being named director general in December.

The lead test rods for the world’s first installed accident tolerant fuel (ATF) have completed a full cycle at Unit 1 of the Hatch nuclear power plant in Baxley, Ga. Southern Nuclear Operating Company operates the two-unit plant.

During a planned spring 2020 maintenance and refueling outage at Unit 1, operators transferred a sampling of the lead test rods from the reactor to the spent fuel pool. An initial inspection of the fuel in comparison to standard zirconium rods has been completed.

Three reactor developers got a boost on March 9 when they were each awarded a contract from the U.S. Department of Defense (DOD) to design a reactor that can fit inside a standard shipping container for military deployment. The DOD’s Strategic Capabilities Office (SCO), in partnership with the Department of Energy, proposes to build and demonstrate a 1–10 MWe reactor within four years that, if successful, could be widely deployed to support the DOD’s domestic and operational energy demands.

BWX Technologies announced on March 11 that its BWXT Nuclear Operations Group (BWXT NOG) subsidiary had been awarded a contract from the Department of Energy’s Oak Ridge National Laboratory to manufacture TRISO nuclear fuel to support the continued development of the Transformational Challenge Reactor (TCR). Plans to restart a TRISO production line at the company’s Lynchburg, Va., manufacturing site will be finalized to allow for production to be completed by the fall of 2020.

The Nuclear Regulatory Commission recently identified a number of what it refers to as “apparent violations” of agency regulations at Tennessee Valley Authority nuclear facilities.

On March 2, the NRC issued TVA an Office of Investigation (OI) report, which pointed to an apparent violation of employee protection requirements at the utility’s Sequoyah nuclear plant, located near Soddy-­Daisy, Tenn. According to the report, a former Sequoyah employee had been “constructively discharged” for raising concerns from 2015 to 2018 with TVA’s Corporate Nuclear Licensing group regarding regulatory noncompliance and for expressing concerns about a chilled work environment. The former employee reportedly expressed these concerns both to TVA’s Employee Concern Program and to other employees.

A group of Republican senators on March 2 penned a letter to Nuclear Regulatory Commission Chairman Kristine Svinicki to express their support for the ROP Enhancement Initiative—an effort to assess and modernize the agency’s nuclear safety inspection program, better known as the Reactor Oversight Process. The letter was signed by Sens. John Barrasso (R., Wyo.), chairman of the Senate Committee on Environment and Public Works; Jim Inhofe (R., Okla.); Shelley Moore Capito (R., W.Va.); Kevin Cramer (R., N.D.); Mike Braun (R., Ind.); Mike Rounds (R., S.D.); John Boozman (R., Ark.); and Roger Wicker (R., Miss.).

As the nuclear industry pursues a new generation of reactors to meet economic and political realities, the process for developing and qualifying new fuels and materials has come into focus. It’s clear that the 30-year development process the industry has come to expect is no longer viable, just as the economic reality of the current reactor fleet is increasingly coming under pressure from low-cost alternatives, particularly natural gas. To reduce carbon emissions while meeting ever-growing energy needs, new nuclear plants must be built soon.

Soon after Enrico Fermi’s Chicago Pile-­1 went critical for a brief duration in December 1942, the construction of the first continuously operating reactor, the X-­10 Graphite Reactor, was initiated in February 1943 at Clinton Engineer Works in Oak Ridge, Tenn. On November 4 of that year, a mere nine months after the start of construction, the reactor began operation. This marked the onset of what Alvin M. Weinberg referred to as “the first nuclear era,” during which many reactors of various designs and operating parameters were built and demonstrated across the United States. Forty years ago, the Fast Flux Test Facility was the last U.S. non-­light-­water reactor to reach criticality, and it has since been decommissioned.

National laboratories from Canada and the United Kingdom have developed an action plan under an existing memorandum of understanding designed to boost collaboration across the areas of clean energy, medical isotopes, waste management, and decommissioning. Canadian Nuclear Laboratories (CNL), Canada’s nuclear science and technology organization, and the National Nuclear Laboratory (NNL), the nuclear services technology provider owned and operated by the United Kingdom, announced the plan on March 4. The agreement will address shared challenges in relation to climate change, public health, and environmental stewardship.

Using a VVER-1200 reactor for Leningrad II Unit 1 has resulted in a nearly 15 percent reduction in cooling water usage at the Leningrad nuclear power plant, according to Rosatom, Russia’s state atomic energy corporation. “The design features of the new power units can significantly reduce the amount of water consumed by a nuclear power plant from natural reservoirs,” said Vladimir Pereguda, director of the plant. He credited the replacing of RBMK-1000 units with VVER-1200 ones for a decrease of 730.7 million cubic meters of seawater withdrawn from Kopory Bay, a 14.8 percent drop in 2019 compared to 2018. Kopory Bay is located in the southern part of the Gulf of Finland on the Baltic Sea. “We will continue to observe such indicators to reduce the environmental impact, since the Leningrad [plant] is gradually replacing RBMK-1000 units with VVER-1200 units,” Pereguda added.

The National Academies of Sciences, Engineering, and Medicine on February 21 released its fourth and final report on its review of possible approaches to treating low-­activity waste at the Hanford Site. The Department of Energy plans to vitrify approximately 56 million gallons of radioactive and chemical waste at the Waste Treatment and Immobilization Plant, which is currently under construction at Hanford. The waste will be separated into high-­level waste and low-­activity waste (LAW) streams before being turned into a solid glass form through vitrification. Not all of the LAW, however, will be vitrified, and the DOE has not determined a treatment method for the excess waste, called supplemental LAW (SLAW).

A report released to the public on February 20 by the Government Accountability Office concluded that maintenance inspections at several contaminated excess facilities at the Department of Energy’s Hanford Site, near Richland, Wash., have not been comprehensive and that there are areas of some facilities that personnel infrequently or never enter, either physically or by remote means, to conduct inspections. The GAO reviewed surveillance and maintenance (S&M) requirements and activities at 18 of Hanford’s approximately 800 excess facilities that require cleanup and found that improvements to the site’s S&M program are needed.
