Coolant flow around the fuel pins in a light water reactor core plays a critical role in determining the reactor’s performance. For yet-to-be-built small modular reactors, a thorough understanding of coolant flow will be key to successfully designing, building, and licensing first-of-a-kind reactors.

Three Illinois nuclear power plants—Byron, Dresden, and Quad Cities—did not clear in last week’s long-delayed PJM Interconnection capacity auction, Exelon Generation reported in a filing with the Securities and Exchange Commission.

The news is likely to further pressure the Illinois General Assembly to pass a comprehensive energy package—one with subsidies for the state’s financially ailing nuclear plants—before Exelon moves forward with its plan, announced last August, to prematurely retire Byron and Dresden.

Oak Ridge National Laboratory has a long record of advancing fusion and fission science and technology. Today, the lab is focused more than ever on taking advantage of that spectrum of nuclear experience to accelerate a viable path to fusion energy and to speed efficient deployment of advanced nuclear technologies to today’s power plants and future fission systems.

The definition of a microreactor is ambiguous. But whether your upper cutoff is 10 MW or 20 MW, the Microreactor Applications Research Validation and Evaluation (MARVEL) reactor that the Department of Energy plans to build is, at 100 kW, on the tiny side of micro.

NRC reports nine abnormal occurrences in FY 2020

June 8, 2021, 6:59AMNuclear News

The Nuclear Regulatory Commission has sent to Congress its annual report on abnormal occurrences involving the medical and industrial uses of radioactive material. An abnormal occurrence is defined by law as an unscheduled incident or event that the NRC determines to be significant from the standpoint of public health or safety. The NRC sets specific criteria, most recently updated in October 2017, for determining which events qualify.

Final cleanup activities at the Hanford Site’s demolished Plutonium Finishing Plant have resumed following a pause in work prompted by the COVID-19 pandemic, the Department of Energy announced. Crews with the DOE’s Richland Operations Office and site contractor Central Plateau Cleanup Company will remove, package, and dispose of rubble remaining from the demolition of the plant’s plutonium reclamation facility, which was torn down in 2017.

Spotlight On: ANS online programming

June 7, 2021, 6:59AMNuclear News

The American Nuclear Society has adapted to the increased digital world during COVID-19. An example of this new flexibility is ANS’s expanded online programming, which presented 28 webinars in 2020, some of which were available only to ANS members. This year during the first quarter, ANS has produced 16 programs on a range of topics, such as the review of the Fukushima accident, the Nuclear Non-Proliferation Treaty at 50 years, and the Spotlight series on the Department of Energy’s national laboratories. The webinars have been well attended and have sparked engaging discussion while most of the world was semi-quarantined.

ANS signs onto letter supporting reintroduction of ANIA

The American Nuclear Society was among 24 nuclear-related companies and organizations that signed a letter urging Senate sponsors of the American Nuclear Infrastructure Act (ANIA) to reintroduce and advance the legislation. The signees represent a broad range of nuclear supporters from the industrial, nonprofit, and advocacy sectors. The letter was sent to Sens. Shelley Moore Capito (R., W.Va.), Mike Crapo (R., Idaho), John Barrasso (R., Wyo.), Cory Booker (D., N.J.), and Sheldon Whitehouse (D., R.I.). Barrasso was the original sponsor of the bill, while Whitehouse, Crapo, and Booker were original cosponsors.

Nuclear I&C Modernization: The Future is Digital

June 4, 2021, 9:34AMSponsored ContentRobert Ammon, Technical Director of Digital Safety Systems at Curtiss-Wright Nuclear Division

As the U.S. nuclear industry moves into plant life extension and subsequent license renewals, the modernization of safety instrumentation and control (I&C) systems holds significant potential to transform plant operations. Automated system diagnostics, equipment health monitoring, and performance indications reduce the need for manual surveillance activities and enable condition-based maintenance, resulting in improved system reliability and reduced maintenance costs. Despite these benefits, adoption of digital I&C systems for safety-related applications across the domestic nuclear fleet has been slow. U.S. nuclear power plants that do choose to embrace the transition from analog to digital are in good company; international plants have successfully implemented digital safety systems for more than a decade. Furthermore, digital safety systems are also the first choice of the growing small modular reactor (SMR) and advanced reactor (AR) communities.

Navy nuclear refueling barge to be dismantled

Towed from its home in Newport News, Va., the U.S. Navy’s Surface Ship Support Barge has arrived in Mobile, Ala., for decommissioning, Advance Local Alabama reported on June 1. The 268-foot-long barge operated from 1964 to 2016, supporting the Navy's nuclear vessel refueling and functioning like a spent fuel pool at a commercial nuclear power plant.

Biden administration’s proposed FY 2022 budget supports nuclear

June 3, 2021, 3:02PMNuclear News

The Biden administration’s fiscal year 2022 budget sent to Congress last week would, according to the Department of Energy, move the United States toward net-zero carbon emissions by 2050. The FY 2022 budget request includes $1.85 billion for the DOE’s Office of Nuclear Energy.

“President Biden’s budget request puts America in the driver's seat as we transition toward a 100 percent clean energy economy,” said secretary of energy Jennifer Granholm on May 28. “These investments will ensure the U.S. is the global leader in research, development, and deployment of critical energy technologies to combat the climate crisis, create good-paying union jobs, and strengthen our communities in all pockets of America.”

TerraPower has a design for a sodium-cooled fast reactor and federal cost-shared demonstration funding from the Department of Energy. Its partner, PacifiCorp, has four operating coal-fired power plants in the state of Wyoming. On June 2, together with Wyoming Gov. Mark Gordon and others, the companies announced plans to site a Natrium reactor demonstration project at a retiring coal plant in Wyoming, with a specific site to be announced by the end of 2021.

Illinois deal likely for Exelon nuclear plants

An energy proposal in Illinois that would keep the state’s nuclear power plants on line while providing incentives for wind and solar generation is likely to be approved by Illinois lawmakers and signed into law by the governor, according to a news report yesterday from Capitol News Illinois.

Senate president Don Harmon (D., Oak Park) noted on June 1 that a deal had been reached between Gov. J. B. Pritzker and Exelon, the parent company of Commonwealth Edison and the owner of six nuclear power plants in Illinois.

Job saver: Approving the energy deal “would save jobs, which has been our goal all along,” Harmon said. “That’s why we support the governor in these talks. We also stand with the governor on decarbonization targets that need to be in a final deal.”

U.S. and France commit to “common ambition” on advanced nuclear

June 2, 2021, 3:12PMNuclear News

U.S. energy secretary Jennifer Granholm and French minister for the ecological transition Barbara Pompili issued a joint statement on May 28 in which they pledged to work together to meet shared climate goals.

“France and the United States share common goals and common resolve in fighting climate change and working toward reaching the ambitious target set forth by the Paris agreement,” the statement read. “We are united in a common ambition on both sides of the Atlantic: achieving net-zero carbon emissions by 2050. Reaching this common objective will require leveraging all currently existing emission-free technologies available to us while simultaneously intensifying research, development, and deployment across a suite of zero-emissions energy sources and systems. Ensuring that these energy systems are efficient and reliable, integrating larger shares of renewables coupled with nuclear energy, which is a significant part of today’s electricity production in both our countries, will be crucial to accelerate energy transitions. Reaching this common objective will also require a wide variety of favorable financing conditions across the range of zero-emitting power sources and systems.”
