Sellafield Vitrification should ensure safe storage of waste in the UK for the middle to long term. Construction of the Sellafield MOX Plant (SMP) was completed in 1997, though justification for the operation of the plant was not achieved until October 2001. Mixed oxide, or MOX fuel, is a blend of plutonium and natural uranium or depleted uranium which behaves similarly (though not identically) to the enriched uranium feed for which most nuclear reactors were designed. MOX fuel is an alternative to low enriched uranium (LEU) fuel used in the light water reactors which predominate in nuclear power generation. MOX also
Beaver Valley Nuclear Power Station an earthquake intense enough to cause core damage to the reactor at Beaver Valley was Reactor 1: 1 in 20,833; Reactor 2: 1 in 45,455, according to an NRC study published in August 2010. Beaver Valley 1 was used as the reference design for the French nuclear plant at Fessenheim. Beaver Valley Nuclear Power Station Beaver Valley Power Station is a nuclear power plant covering near Shippingport, Pennsylvania, United States, roughly northwest of Pittsburgh. The Beaver Valley plant is operated by FirstEnergy Nuclear Operating Corporation. This plant has two Westinghouse pressurized water reactors. While the Shippingport Reactor has been decommissioned,
