Connecticut Yankee
Location: CT
Operator: Connecticut Yankee Atomic Power Co
Configuration: 1 X 600 MW PWR
Operation: 1968 (ret 1996)
Reactor supplier: WH
T/G supplier: WH
EPC: Stone & Webster
Quick facts: CY generated electricity for the first time on 7 Aug 1967 and began commercial operation on 1 Jan 1968 rated at 490 MWe, just 6yrs after project inception. On 15 Nov 1998, at 11:11am, the last fuel assembly was removed from the reactor core and placed in the spent fuel pool leaving 1,019 fuel assemblies at the station for long term storage. For 2yrs, CY was the largest nuclear unit in the world. Over 28yrs of operation, the unit generated over 110 TWh of electricity and held the continuous run world record for a PWR two times. On 2 Sep 1989, CY became the first nuclear unit to break the 400-day continuous run mark twice. Connecticut Yankee had a lifetime capacity factor of 71%. Most of the 500ac site was officially decommissioned and released for unrestricted use on 26 Nov 2007. A 5ac parcel is maintained for a dry cask fuel storage facility.

Vermont Yankee
Location: VT
Operator: Entergy Nuclear Inc
Configuration: 1 X 635 MW BWR
Operation: 1972 (ret 2014)
Reactor supplier: GE
T/G supplier: GE
EPC: Ebasco
Quick facts: Vermont Yankee is on the Connecticut River, 10mn south of Brattleboro. In 2002, Entergy bought the plant from Vermont Yankee Nuclear Power Corp, a JV of thirteen electric utilities in New England. In May 2000, Vermont Yankee's cumulative generation reached 100mn MWh.This generating unit generally provided about one-third of the electricity used in Vermont. In Aug 2013, Entergy announed it was closing the plant for economic reasons and the unit shutdown on 29 Dec 2014. In Jul 2017, AREVA was contracted to segment, package and transport to offsite disposal the RPV and internals. It is expected to cost about $1.25bn to decommission Vermont Yankee. A Power Plant Trading Card was made for this plant.
