Entergy - the owners of Pilgrim Nuclear Power Plant - may select from three decommissioning strategies:
DECON (immediate dismantling), soon after the nuclear facility closes, equipment, structures, and portions of the facility containing radioactive contaminants are removed or decontaminated to a level that permits release of the property and termination of the NRC license.
SAFSTOR (deferred dismantling), a nuclear facility is maintained and monitored in a condition that allows the radioactivity to decay; afterwards, the plant is dismantled and the property decontaminated.
ENTOMB, radioactive contaminants are permanently encased on site in structurally sound material such as concrete. The facility is maintained and monitored until the radioactivity decays to a level permitting restricted release of the property. To date, no NRC-licensed facilities have requested this option.
Entergy officials say they have not yet committed to one particular strategy, except to rule out ENTOMB, which has never been utilized for a decommissioned plant in the U.S.
