Nuclear Licesning Board examines vessel risks at Entergy's Palisades atomic reactor; critics call for permanent shutdown

NRC file photo of Entergy Nuclear's Palisades atomic reactor on the Lake Michigan shore in Covert, MIAs reported by a press release, a coalition of environmental groups, including Beyond Nuclear, today testified before the U.S. Nuclear Regulatory Commission's (NRC) Atomic Safety and Licensing Board (ASLB), at the agency's HQ in Rockville, Maryland, just outside D.C.

The coalition, represented by Toledo attorney Terry Lodge, defended its intervention against an Entergy License Amendment Request (LAR) to further weaken reactor pressure vessel (RPV) embrittlement/pressurized thermal shock (PTS) safety regulations.

Palisades has the worst-embrittled RPV in the U.S., at risk of a PTS fracture, Loss-of-Coolant-Accident, core meltdown, and catastrophic release of hazardous radioactivity. A bad precedent at Palisades will then be applied by NRC to approve operations at other dangerously brittle pressurized water reactor (PWR) RPVs across the U.S.

The coalition intervened on Dec. 1, 2014. Entergy Nuclear and NRC staff counter-attacked on Jan. 12, 2015. The coalition rebutted the attacks on Jan. 20.

Today's "oral argument pre-hearing" was essentially an ASLB exercise to determine whether the coalition's intervenion is worthy of an evidentiary hearing on the merits of the contention. The ASLB is scheduled to rule on the admissibility of the intervenors' contention within 45 days.

On March 9, the coalition filed a parallel intervention regarding loss of Charpy V-Notch Upper-Shelf Energy in Palisades RPV, another form of age-related degradation.

From 2005 to 2007, a broad environmental coalition sought to block Palisades' 20-year license extension. The coalition's main safety objection was PTS risks. NRC rubber-stamped the extension anyway.
