The U.S. Nuclear Regulatory Commission (NRC) said it has dismissed a license application for one of the first advanced nuclear reactor designs to be considered by the agency. The NRC on Jan. 6 said it could not make a judgment on the merits of the design of Oklo Inc.’s 1.5-MW advanced fission power system, known […]

Improvements in nuclear power technology are being driven by research into safer reactor designs and new fuel types, including smaller reactors that offer flexible siting options with modular construction

Ontario Power Generation (OPG) will build a GE Hitachi Nuclear Energy (GEH) BWRX-300 small modular reactor (SMR) at its Darlington Nuclear Station in Clarington, Ontario, marking a major triumph for the nuclear vendor in a stiff competition for the much-watched utility-scale project. OPG announced the selection of the GE Hitachi BWRX-300 SMR over competitors X-energy […]

Potentially jumpstarting long-paralyzed efforts to address the federal management of spent nuclear fuel (SNF), the U.S. Department of Energy (DOE) on Nov. 30 issued a request for information (RFI) that could determine where the agency will temporarily consolidate and store spent fuel from nuclear reactors across the nation. Under the RFI, the DOE is seeking […]

Terrestrial Energy has unveiled an upgraded 390-MWe design of its Integral Molten Salt Reactor (IMSR) power plant to meet utility requirements and boost its cost-competitiveness as part of an effort to ramp up its candidacy for deployment at Ontario Power Generation’s (OPG’s) Darlington Nuclear Generating Station. This week, the Canadian firm also announced a series […]

Holtec International’s ambitions to install its first set of SMR-160 small modular reactor nuclear plants in the U.S. by 2030 may be a “credible target,” the company’s advisory council comprising 20 utility and nuclear industry leaders has reportedly determined.  The Holtec Advisory Council, a body that provides Holtec with “input on the technical and commercial merits […]

Marking another milestone in an industry-led accelerated quest to commercialize accident tolerant fuels (ATF), nuclear fuel test rods containing Westinghouse’s EnCore technologies that completed their inaugural cycle at Exelon’s Byron nuclear plant have shipped to Oak Ridge National Laboratory (ORNL). While initial visual inspections show “no signs of degradation,” the irradiated fuel will now be […]

Exelon Generation has filed plans to decommission its Dresden and Byron nuclear power plants in Illinois, citing a lack of action from state lawmakers on clean energy legislation that would help save the facilities. The nation’s largest operator of nuclear power plants on July 28 said it has submitted its plans to the Nuclear Regulatory […]

The University of Illinois at Urbana-Champaign (UIUC) has formally kicked off a pioneering project to partly re-power its 85-MW Abbott cogeneration plant with an Ultra Safe Nuclear Corp. (USNC) Micro Modular Reactor (MMR) Energy System. UIUC on June 28 said it submitted a letter of intent to the U.S. Nuclear Regulatory Commission (NRC) to build […]

The U.S. Nuclear Regulatory Commission (NRC) has given its green light to a license amendment filed by Centrus Energy Corp., approving the nuclear fuel and services firm’s efforts to demonstrate High-Assay, Low-Enriched Uranium (HALEU) production at its enrichment facility in Piketon, Ohio.  The approval marks a “major milestone” in Centrus’s $115 million, cost-shared contract with the […]
