According to a report from the Nuclear Regulatory Commission, Entergy has more than $676 million in trust to decommission Pilgrim Nuclear Power Station, which is more than enough to meet the NRC's requirements for such a fund.
The NRC's minimum for Pilgrim is $578,934,126. Entergy, and its predecessor Boston Edison, have $676,660,000 in trust.
The official report is attached.
According to the NRC:
all power reactor licensees are required to submit a DFS report at least once every 2 years in order for the NRC to obtain the information necessary to monitor the status of decommissioning funds. Any licensee for a plant involved in a merger or acquisition shall submit this report annually. Any licensee for a plant that is within 5 years of the end of its current operating license shall submit this report annually. Any licensee for a plant that has already closed before its licensed life shall submit this report annually. As of December 31, 2011, Indian Point Nuclear Generating Station, Units 2 & 3, and Pilgrim Nuclear Power Station are within 5 years of the end of its current operating license.
