SNL: "Palisades plant critics vow to continue fight over 'thermal shock' issue" (risks extend to Pt. Beach, Indian Pt., Diablo, & Beaver Valley)

Entergy's Palisades atomic reactor, located on the Lake Michigan shoreline in southwest Michigan.SNL Financial has published an in-depth investigative article by Matthew Bandyk, "Palisades nuclear plant critics vow to continue fight over 'thermal shock' issue."

The article revealed that Palisades' previous owner, Consumers Energy, had planned to attempt to repair the severely neutron radiation embrittled reactor pressure vessel (RPV), by undertaking experimental, expensive annealing (super-heating the metal in an attempt to restore ductility) in the late 1990s, but decided not to, for fear of public backlash and/or legal intervention against the needed License Amendment Request.

An environmental coalition, including Don't Waste MI and NIRS, battled against the Palisades' 20-year license extension rubber-stamp by NRC, but lost in early 2007. The coalition's top safety concern was RPV embrittlement/PTS risk.
