SINGLE UNIT DECOMMISSIONED REACTORS IN THE US
research by Safe & Green Campaign
DECON
From 1962 to 1998, all single unit reactors in the US went into DECON – not SAFSTOR.
No single units closed between 1998 and 2012.
The only single unit reactors to go into SAFSTOR to date are Kewaunee and Vermont Yankee, which closed in 2013 and 2104.
- 8 single-reactor sites went to DECON, not SAFSTOR, and decommissioning is now complete: Connecticut Yankee, Maine Yankee, Yankee Rowe, Big Rock, Shoreham, Shippingport, Saxton, Rancho Seco.
- 3 sites are still in DECON (Zion, Humbolt Bay, LaCrosse).
- San Onofre has 3 units, all are now closed (as of 2014). It is in SAFSTOR.
- Before now, all the reactors currently in SAFSTOR shared the site with operating reactors or other generating plants. On multi-unit sites it makes economic and environmental sense to decommission multi-units all at once, when they are all closed.
CURRENT USE
Single unit fully decommissioned site are used either
- natural parks / conservation areas
- for other energy production
- undecided to date, or undeveloped
