NRC may increase oversight of Pilgrim nuclear power plant

The U.S. Nuclear Regulatory Commission (NRC) may increase oversight at the Pilgrim nuclear power plant in Massachusetts.
Plant operator Entergy (NYSE:ETR) has been given 10 days to respond to the report, according to The Patriot Ledger. The report stems from the reactor shutting down during the January blizzard that hit the region when distribution lines became inoperable. The article said one of the complications involved the failure of one of four safety relief valves to open as part of the cool-down process. Inspectors arrived on site in February and said in the 68-page report that Entergy could have prevented the issue if it addressed a previous valve problem from a shutdown during a February 2013 storm, the article said. Inspectors also looked into the failure of a condensate pump motor associated with the plant’s High-Pressure Coolant Injection system and the partial loss of off-site power.
Pilgrim is currently in the “degraded cornerstone” category in the NRC’s performance assessment, which puts it under closer scrutiny.
An Entergy spokesperson said in the article that Entergy had addressed all of the NRC’s concerns, including installation of four new safety relief valves during a refueling outage.
