The Nuclear Regulatory Commission’s Office of Nuclear Regulatory Research is hosting two workshops on reactor topics before the end of the year.
Utah Associated Municipal Power Systems (UAMPS) and NuScale Power announced November 8 that they have mutually agreed to end the Carbon Free Power Project (CFPP)—a plan to build a set of 77-MWe pressurized water reactors, called NuScale Power Modules, at Idaho National Laboratory. The reactors were intended to provide power to INL and UAMPS customers in Utah and surrounding states with an anticipated start date of 2029.
In celebration of Hispanic Heritage Month this year, which ran September 15-October 15, the American Nuclear Society hosted the webinar “Hispanic Excellence in the Nuclear Field” on September 20. The panelists shared insights from their accomplished careers and relayed personal anecdotes and practical advice to young nuclear professionals. They also voiced their thoughts about challenges and opportunities facing the Hispanic community in the field.
The Department of Energy’s National Reactor Innovation Center (NRIC) awarded $3.9 million to three advanced nuclear energy developers on October 23 to design experiments to test microreactor designs in the Demonstration of Microreactor Experiments (DOME) test bed at Idaho National Laboratory.
The Department of Energy’s Office of Environmental Management said that crews at the Idaho National Laboratory site are making “significant progress” decommissioning the Submarine 1st Generation Westinghouse (S1W) reactor, the prototype pressurized water reactor that supported the development of the USS Nautilus, the world’s first operational nuclear-powered submarine.
The Department of Energy has released two additional requests for information related to its Cleanup to Clean Energy initiative, which aims to repurpose certain DOE-owned lands—portions of which were previously used during the nation’s nuclear weapons program—into sites for clean energy generation, including include solar, geothermal, wind, and nuclear electricity.
Researchers at Idaho National Laboratory have a new experimental tool to study nuclear fuel under simulated loss of coolant accident (LOCA) conditions in INL’s Transient Reactor Test (TREAT) Facility. A specialized experiment holder called a TWIST capsule holds a fuel sample surrounded by water, which can rapidly drain away during testing, simulating loss of coolant in a light water reactor environment.
When Norway’s Halden research reactor shut down in 2018, nuclear researchers around the world were forced to scramble. For 60 years, the Halden Reactor Project offered a 25-MWt boiling water reactor for research where scientists could expand their understanding of nuclear fuel reliability, reactor internals, plant procedures and monitoring, and human factors.
While initial operation of MARVEL, a tiny microreactor that will be installed and operated inside Idaho National Laboratory’s Transient Reactor Test (TREAT) Facility, might not occur until 2025, testing of a nonnuclear prototype is now under way at the New Freedom, Pa., manufacturing facility of Creative Engineers, Inc. (CEI). The Department of Energy announced the start of prototype testing on September 20.
This year’s American Nuclear Society Annual Meeting was filled with great content, some of which was covered in the August issue of Nuclear News (beginning on p. 22). One of the meeting’s executive sessions, “Bringing Nuclear History Forward,” focused on advanced reactor (AR) history and was well attended. The United States—along with many countries around the world—is turning to nuclear to combat climate change. Part of this is funding new and innovative companies to create first-of-a-kind nuclear reactors to provide abundant and clean power. Looking at the current designs of interest to the community brings up interesting comparisons to the test and experimental reactors of the past. Test reactors like the Experimental Breeder Reactor-II (EBR-II), the Fast Flux Test Facility (FFTF), Peach Bottom, Fort St. Vrain, Germany’s AVR, and others now are more important than ever in providing insight, data, and operational lessons learned to develop the next generation of reactors.
Abilene Christian University’s Gayle and Max Dillard Science and Engineering Research Center (SERC) has opened. SERC contains the Nuclear Energy eXperimental Testing Laboratory (NEXT Lab) and is the future home of one of the first advanced reactors in the United States. More than 300 people were on hand to celebrate the opening and tour the facility, including donors, government officials, and scientists from ACU and other research institutions.
Senior advisor Ike White and others with the Department of Energy’s Office of Environmental Management traveled to Japan this week to attend the 7th International Forum on the Decommissioning of the Fukushima Daiichi Nuclear Power Station.
The American Nuclear Society Diversity and Inclusion in ANS Committee hosted a webinar this summer on the impact of national, state, and local policies on the nuclear workforce. The event addressed the question of how the nuclear sector can become a more supportive work environment and accommodate aspects like identity or disability that make us different and human.
The webinar, DIA Roundtable: The Impact of National, State, and Local Policies on the Nuclear Workforce, is open to all users.
Oklo Inc. and Centrus Energy announced a new memorandum of understanding on August 28 to support the deployment of Oklo’s microreactor design, dubbed Aurora, near the Piketon, Ohio, site where Centrus plans to operate a high-assay, low-enriched uranium (HALEU) enrichment demonstration under contract to the Department of Energy by the end of the year.
Deploying microreactor technology for military applications could have huge impacts on logistics and reliability for the military of the future, and on the commercial use of similar technologies. That’s why the Department of Defense is developing Project Pele—a high-temperature, gas-cooled and TRISO-fueled microreactor, transportable within mobile shipping containers—for testing at Idaho National Laboratory in 2025.
As global concerns about climate change and energy sustainability intensify, the need for cleaner and more efficient energy sources is more critical than ever. Nuclear power consistently emerges as an important part of the solution, driving the development of innovative technologies. While numerous fission technologies were built and proven in the early days of nuclear energy, times and regulations have changed. Between the 1950s and mid-1970s, Idaho National Laboratory built 52 reactors—then paused for five decades. Can this nation return to the frontier once again, embarking on new fission technologies? With a mature regulatory environment and increasing public support, how quickly can a new non–light water system be deployed in modern times?
The Idaho National Laboratory is moving closer toward closing its largest building—which, at more than 316,000 square feet, could comfortably house a modern U.S. aircraft carrier, according to the Department of Energy.
The Department of Energy today released its final environmental assessment (EA) and a proposed finding of no significant impact (FONSI) for the design, construction, and operation of the Molten Chloride Reactor Experiment (MCRE) at Idaho National Laboratory. The draft EA was released earlier this year, in March, for four weeks of public comments.
Kairos Power has filed a construction permit application with the Nuclear Regulatory Commission for a two-unit version of its Hermes advanced test reactor.
The Nuclear Regulatory Commission staff has completed its final safety evaluation for Kairos Power’s application to build its Hermes advanced test reactor at a site in Oak Ridge, Tenn., the agency announced recently. The evaluation found no safety aspects precluding issuance of a construction permit for the proposed reactor.
