US NRC file photo of Point Beach nuclear power plant, on WI's Lake Michigan shorelinePoint Beach Unit 1 experienced a troubled manual shutdown on July 31st -- just two days after an NRC licensing board rejected all of Physicians for Social Responsibility Wisconsin's expert-backed contentions, opposing 30 more years of high-risk operations at the half-century old nuclear power plant on the Lake Michigan shore.PSR WI expert Arnie Gundersen, Chief Engineer at Fairewinds Associates, analyzed the trip, identifying four separate problems, focusing on aging-related degradation aspects of the root cause. PSR WI has requested an NRC Augmented Inspection Team to examine the incident. At the same time, Nukewatch Wisconsin's John LaForge has documented that emergency sirens have been turned off at the plant. We are honored to advise PSR WI.
