Advanced reactors are promising energy systems that can enable the world to transition to a more sustainable energy matrix. These concepts are potentially more fuel efficient and safer, compared with previous generations of nuclear reactors. Many designs, like high-­temperature gas reactors (HTGRs) and molten salt fast reactors (MSFRs), target high outlet temperatures, allowing for their operation in processes where high heating is required, such as for hydrogen production and desalination.

Georgia Power has begun the process of loading fuel into the Vogtle plant’s Unit 4 reactor, the company announced yesterday, marking another pivotal milestone toward commercial operation of the second of the facility’s two new units.

A Nuclear Regulatory Commission draft regulatory guide—DG-8061, “Release of Patients Administered Radioactive Material”—proposes guidance on the release of patients after a medical procedure involving the administration of radiopharmaceuticals or the implantation of a sealed source. The guidance is intended to help licensees interpret NRC regulations designed to protect the people—family, friends, caregivers, or members of the general public—who may be in proximity to a patient who is discharged after receiving nuclear medicine treatment.

Duke Energy has filed an update to its 2022 state-mandated carbon-reduction plan with the public utility commissions of North and South Carolina, proposing the deployment of small modular reactors at the Belews Creek coal plant in Stokes County, N.C., which is slated for retirement next decade. A similar system would be added at a second site yet to be determined for a total of 600 MW of advanced nuclear. (Both the advanced reactor production tax credit and investment tax credit included in last year’s Inflation Reduction Act offer a 10 percent bonus for facilities sited in certain energy communities, including those with retiring coal plants.)

The United States has joined the OECD Nuclear Energy Agency (NEA) Data Bank, a decision that marks “a significant stride in international collaboration for nuclear energy research, safety, and knowledge exchange,” according to the August 16 NEA announcement. “As a country renowned for its scientific and technological excellence, the United States will undoubtedly enrich the Data Bank's repository of data, software, and benchmarks and enhance its role in fostering responsible nuclear development.”

Nuclear thermal hydraulics—for light water reactors or advanced reactors cooled by gas, metal, or salt—is all about defining safety and performance margins as things heat up.

After decades of planning and weeks of preparation and checks, the first batch of legacy waste has been retrieved from the Pile Fuel Cladding Silo at the Sellafield nuclear site in West Cumbria, England. According to Sellafield Ltd., the site license company, a state-of-the-art robotic arm was used to reach into the silo and, for the first time, remove and repackage the waste for longer-term storage.

These retrievals mark a significant achievement in progress toward the cleanup and decommissioning of one of the most hazardous buildings on the site, according to Sellafield Ltd., which made the announcement on August 16.

Energy and security company IP3 has announced an agreement with Green Energy Partners (GEP), a property and project development firm, to pursue clean energy projects by establishing the Surry Green Energy Center “to implement innovative commercial plans targeting baseload and industrial energy needs in Virginia.”

The American Nuclear Society will be hosting a special online event on Friday, August 25, at 11:00 am (ET). The webinar Oppenheimer: Behind the Scenes with Los Alamos National Laboratory will feature representatives from LANL, who will discuss the blockbuster feature Oppenheimer, directed by Christopher Nolan, which premiered last month in theaters.

The Department of Energy’s Savannah River Site in South Carolina will begin a leak tightness test on what it called “the fourth megavolume saltstone disposal unit (SDU)” at the site.

Robotics experts from Sandia National Laboratories and representatives from the Department of Energy Office of Environmental Management’s Technology Development Office recently visited the Sellafield nuclear site in England to discuss how robotics, artificial intelligence, and other emerging tools can be developed and used in nuclear cleanup operations.

The Department of Energy’s Office of Environmental Management said that crews have completed major deactivation efforts at the Alpha-2 building at the Y-12 National Security Complex in Oak Ridge, Tenn. The former uranium enrichment facility is scheduled for demolition next year.

Nuclear research reactors throughout the world enable crucial scientific progress that benefit many sectors, health care and the environment among them. But some of those reactors need an important adjustment: a conversion from using high-enriched uranium fuel to using low-enriched uranium fuel.

The Nuclear Regulatory Commission has directed its staff to issue a final rule and associated regulatory guide that applies risk-informed, performance-based emergency preparedness requirements to small modular reactors and other new technologies, the agency announced on August 14. The technologies include non–light water reactors, research and test reactors, and medical radioisotope facilities.

Québec government–owned utility Hydro-Québec, Canada’s largest power provider, is looking into the feasibility of restarting Unit 2 at the Gentilly nuclear power plant, various Canadian news outlets reported last week.

The Department of Energy’s Office of Science announced $112 million in funding on August 14 for 12 projects designed by fusion scientists, applied mathematicians, and computer scientists to apply high-performance computing and exascale computers to complex fusion energy problems.

The list of projects and more information can be found on the Fusion Energy Sciences homepage.

The Department of Energy today announced a noncompetitive financial assistance cooperative agreement with Southeast New Mexico College, located in Carlsbad, N.M., for educational programs to enhance the knowledge, skills, and abilities of current Waste Isolation Pilot Plant employees while also building and training WIPP’s next-generation workforce.

The Department of Commerce’s Bureau of Industry and Security (BIS) has expanded the scope of its nuclear-related export controls on China and Macao (a special administrative region in southeastern China) by establishing additional nuclear nonproliferation controls and license requirements for items that could “contribute to nuclear activities of concern.” The BIS stated that the action, effective August 11, was taken in response to China’s military modernization and nuclear force expansion.

Rezin

Pritzker

Nuclear advocates may have applauded Illinois Gov. J.B. Pritzker two years ago when he signed legislation providing $694 million to three of the state’s struggling nuclear power plants, but they’re hissing him now: On Friday, Pritzker vetoed S.B. 76, a bill that would have lifted the state’s decades-old moratorium on new nuclear power plant construction.

Introduced in January by Sen. Sue Rezin (R., 38th Dist.), S.B. 76 called for deleting language in the Illinois Public Utilities Act that forbids nuclear plant construction in the state until the Illinois Environmental Protection Agency determines that the federal government “has identified and approved a demonstrable technology or means for the disposal of high-level nuclear waste, or until such construction has been specifically approved by a statute enacted by the General Assembly.”

The International Atomic Energy Agency is launching a new Coordinated Research Project (CRP) to increase international knowledge and drive progress toward testing deep borehole disposal for intermediate- and high-level radioactive waste.
