Arnie, Chief Engineer at Fairewinds Associates, Inc., serves as expert witness for an environmental coalition, including Beyond Nuclear, challenging Entergy Nuclear's application to weaken reactor pressure vessel (RPV) embrittlement safety standards, yet again, at its Palisades atomic reactor in s.w. MI on the Lake Michigan shoreline. Palisades has the worst embrittled RPV in the U.S., at risk of pressurized thermal shock (PTS), fracture, Loss-of-Coolant-Accident, core meltdown, containment failure, and catastrophic release of hazardous radioactivity.
NRC rubber-stamped Palisades' 20-year license extension in 2007, steamrolling an environmental coalition's intervention in opposition. The primary technical safety focus of the coalition was RPV embrittlement and PTS risk. See the chronicle of this 2005-2007 intervenion, posted online at the NIRS website.
