TWELVE SMRs PLANNED FOR ENERGY NORTHWEST Energy Northwest recently announced plans to build and operate 12 SMRs (small modular reactors) in an area just north of Richland, Washington adjacent to their nuclear plant Columbia Generating Station. Columbia Generating Station provides Washington State with about 10% of its electricity, producing 1,207 MWe (megawatts electric), when operating at 100% power. It was built and operated by the Washington Public Power Supply System (WPPS) in 1984 until it changed its name in 1998 to Energy Northwest, which now operates the plant and leases the 580 square-mile site. It is the sole nuclear power plant in the Pacific Northwest and one of only three within the western United States (Columbia Generating Station, Palo Verde Generating Station, and Diablo Canyon Power Plant). Energy Northwest agreed to a partnership with X-Energy Reactor Company, a Rockville, Maryland-based firm that manufactures nuclear fuel and reactors. X-Energy’s SMR, Xe-100, uses their own TRISO particle fuel. This HTGR (high temperature gas-cooled reactor) design produces 80 MWe and is designed for a 60-year operational lifetime with the benefit of online refueling. State lawmakers approved $25 million for the project in March 2024 and the Biden administration has announced plans to “bolster domestic nuclear industry” and backed a multi-country declaration to triple nuclear energy capacity globally by 2050. A specific time frame for these SMRs was not disclosed. #energyindustry #powergeneration #nuclearenergy #nuclearpower #renewableenergy #renewables photo credit: energy-northwest.com

Why multiple SMRs rather than multiple full scale reactors?
