Four of six Illinois nuclear power plants—Braidwood, Byron, LaSalle, and Quad Cities—set operational records while conducting spring refueling outages amid the COVID-19 pandemic.
Performance records include the shortest refueling outage (18 days) at LaSalle; the shortest refueling outage at Quad Cities (16 days), as well as the completion of the site’s longest continuous run (722 days); and the completion at both Braidwood and Byron of their sixth consecutive continuous cycle of operations, also known as a “breaker-to-breaker” run, according to a May 7 press release from Exelon Generation. Exelon’s average outage duration in Illinois this spring was 17 days, a full two weeks shorter than the national average, the release stated.

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) has issued a report recommending approval of Dominion Energy’s 20-year subsequent license renewal (SLR) application for Surry-1 and -2. The board reached its conclusion during its April meeting, after reviewing both the SLR application and the associated final safety evaluation report. Dominion submitted the application in October 2018.
A request to the Nuclear Regulatory Commission that it suspend all rulemakings and other activities involving public comment or participation has failed to receive the petitioners’ desired response from the agency.
In a letter dated April 8, representatives of 82 largely antinuclear organizations—including Beyond Nuclear, the Natural Resources Defense Council, the Nuclear Information and Resource Service, Public Citizen, and the Sierra Club—argue that the public’s role in NRC rulemaking and licensing decisions is not being properly protected during the coronavirus pandemic.

Nuclear energy demand and output could be reduced by 2.5 percent this year compared with 2019, according to the report Global Energy Review 2020 from the International Energy Agency (IEA). The report states that global nuclear power generation fell by about 3 percent in the first quarter of 2020 compared with the same period in 2019, adding that the decline was due to lower electricity demand as well as delays for planned maintenance and construction of several projects.
The Nuclear Regulatory Commission is developing a generic environmental impact statement (GEIS) for small-scale advanced reactor designs. Just how small a reactor must be to fit the parameters of the GEIS is one topic open for public comment, but the NRC staff anticipates including reactors generating up to 30 MWt. The public comment period is open until June 30
Robert Feitel, speaking at his December 3, 2019, nomination hearing before the Senate Environment and Public Works Committee’s Subcommittee on Clean Air and Nuclear Safety.
The Senate voted unanimously 87–0 on May 4 to confirm Robert Feitel as the inspector general of the Nuclear Regulatory Commission. The position had been vacant since the end of 2018, when the NRC’s longtime IG Hubert T. Bell retired.
A Department of Justice attorney, Feitel was nominated for the job by President Trump in October last year, and in December he was approved by the Senate’s Environment and Public Works Committee, also by unanimous vote.
When it comes to advanced, high-temperature reactors—using working fluids such as molten salt, high-temperature gases, or sodium—there simply are not many qualified materials for nuclear component construction. Alloy 617 is not a new material, but it made the news after Idaho National Laboratory announced that it was recently added to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (BPV) Code for high-temperature nuclear applications, bringing the total number of qualified high-temperature materials to six.

Despite its recent decision to trim the workforce at the Vogtle reactor construction project by about 20 percent to better address the COVID-19 pandemic, Southern Company is confident that Units 3 and 4—twin AP 1000 pressurized water reactors—will be up and running according to schedule.
Belgium’s National Institute of Radioelements (IRE) announced on April 30 that it has produced its first batch of commercial molybdenum-99 from low-enriched uranium (LEU) targets. The first batch of Mo-99, whose decay product, technetium-99m, is used in nuclear medicine for diagnostic imaging, was produced for the U.S. health market. IRE said that the conversion to LEU represents a key milestone for the institute in the global commitment to end the civilian use of highly enriched uranium (HEU) for the production of Mo-99.
A Michigan antinuclear group will have an opportunity next month to explain to an Atomic Safety and Licensing Board why there should be a public hearing on a license amendment request (LAR) concerning the fuel racks used in the Fermi-2 spent fuel pool (SFP).

South Korea’s Hyundai Heavy Industries (HHI) has completed work on the first vacuum vessel section for the International Thermonuclear Experimental Reactor (ITER), the ITER Organization reported on April 28. The 440-ton section is now being prepared for shipping this summer to the ITER construction site, located near Saint-Paul-lez-Durance, France.
BWX Technologies has announced the successful formation and sintering of uranium oxycarbide (UCO) fuel kernels that, once coated, will make up the fissile core of TRISO (tristructural isotropic) fuel particles. With that process demonstrated, BWXT has shifted the focus of its TRISO production restart to bringing two more furnaces online—an additional sintering furnace, used to apply heat and pressure to a solid fuel kernel, and a coating furnace.
High-assay low-enriched uranium (HALEU) is the fuel of choice for many advanced reactor developers, including Advanced Reactor Concepts, which is designing the ARC-100, a sodium-cooled fast reactor. Developers face a potential supply problem, however: The United States has no clear path to build the commercial HALEU production facilities that would be needed to fuel a fleet of advanced reactors. A letter of intent signed by ARC and Centrus Energy, announced on April 28, calls for cooperation on the deployment of a commercial supply of HALEU and could lead to a HALEU purchase agreement for ARC-100 deployments in the late 2020s.
The Department of Energy announced on April 28 that the Southern Ohio Diversification Initiative (SODI) and the Southern Nuclear Development LLC (SND) would receive funding for their advanced nuclear technology development projects. The two awards—one to support site preparation for a future domestic advanced reactor demonstration project and the other for an advanced reactor regulatory licensing grant—have a total value of $5.4 million.
The New Jersey Board of Public Utilities (NJBPU), along with the Public Service Commission of Maryland, on April 27 filed a petition with the U.S. Court of Appeals, requesting a review of an April 16 ruling by the Federal Energy Regulatory Commission that largely upheld its December 2019 order regarding PJM Interconnection’s forward-looking capacity auctions. The controversial order instructed PJM to expand its minimum offer price rule (MOPR) to include new and existing energy resources, including nuclear and renewables, that receive state subsidies. PJM operates the largest wholesale competitive electricity market in the country, covering 13 states and the District of Columbia.

The long-awaited report from the Trump administration’s Nuclear Fuel Working Group promises immediate support for the front end of the nuclear fuel cycle, but it doesn’t stop there. “This is a road map for what we think needs to be done to not only revitalize, but reestablish American leadership for this entire industry,” said Energy Secretary Dan Brouillette as he introduced the report during a press call on April 23.
The Department of Energy will provide $12 million for research in quantum information science (QIS) for fusion energy and plasma science. The research is expected to focus on a range of topics, including the design of quantum computing algorithms to solve problems in fusion energy, the development of quantum sensing diagnostics for fusion experiments, and the formation of novel quantum materials using high-energy-density plasmas.
Control room operators at Entergy Corporation’s Indian Point Unit 2 will permanently shut down the 1,028-MWe pressurized water reactor today, April 30, after more than 45 years of producing electricity for New York. The remaining operating reactor at Indian Point, the 1,041-MWe Unit 3, is scheduled to be retired exactly one year from now, on April 30, 2021.
The Department of Energy’s Office of Science is inviting input on its plan to develop a cost-share program in fusion reactor technologies. A request for information was published in the Federal Register, inviting interested parties to comment on the topical areas, program objectives, eligibility requirements, program organization and structure, public and private roles and responsibilities, funding modalities, and assessment criteria of such an initiative.
