Zion
Location: IL
Operator: Exelon Nuclear
Configuration: 2 X 1,098 MW PWR
Operation: 1973-1974 (ret 1998)
Reactor supplier: WH
T/G supplier: WH
EPC: S&L, Commonwealth Edison
Quick facts: In 1998, both units' generators were converted to synchronous condensers. These were used year-round to provide regional transmission system stability. In Aug 2010, Exelon announced a $1bn, 10yr decommissioning plan for Zion, the largest to date in the USA. Exelon plans to transfer the station license to EnergySolutions, a nuclear services company that will dismantle the plant and dispose of all low-level radioactive waste at its Clive, Utah, waste facility. Exelon will retain ownership of spent fuel and other high-level radwaste which will be dry-stored onsite. Afterwards, much of the 200ac site 40mi north of Chicago will be available for unrestricted use.
