Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.
Westinghouse Electric Company is the world's leading supplier of new nuclear plants, products and technologies. We provide our utility customers around the world with the most reliable, dependable nuclear power plants, nuclear fuel, plant automation and operating plant products and services. Our AP1000© reactor is the only operating Generation III+ reactor with fully passive safety systems, modular construction design and has the smallest footprint per MWe on the market. Our AP300™ SMR, which launched this year, is single-loop pressurized water reactor that is based on the proven, licensed AP1000 technology. In addition to these advanced LWRs, Westinghouse is also developing non-traditional nuclear technologies in order to meet the needs of diverse and evolving global markets. Specifically, the Westinghouse eVinci™ microreactor is designed to provide approximately 5 megawatts of electricity / 15 megawatts of thermal power 24 hours a day, 7 days a week for eight-plus years without refueling. The Westinghouse Lead-cooled Fast Reactor is a utility-scale (450 MWe) Generation IV plant designed to best complement advanced passive LWRs through enhanced application versatility that combines flexible cost-competitive electricity, high-temperature heat and the capability to support a closed fuel cycle. Our comprehensive and innovative technology portfolio creates a blueprint for a carbon-free ecosystem that serves communities large and small with reliable, cost-effective electricity, district and process heat, and water desalination.
