Update on NRC Event Reports: Comanche Peak restores offsite power and Hope Creek reactor crashes on restart


 
The Nuclear Regulatory Commission’s Event Reports page has updates on two items that I told you about yesterday:
 
First, the Comanche Peak nuclear powerplant in North Texas restored offsite power to both reactors, which had been on emergency diesel generator power after an offsite electrical cable was cut in a still-unexplained accident. Comanche Peak continued to operate both units at 100 per cent output after the cable problem. Most sensible people, I think, would have preferred that the reactors be powered down during a loss of offsite power accident.

Second, operators at New Jersey’s Hope Creek nuclear power facility, where the Unit 1 reactor shut itself down last Sunday morning following a turbine trip, were attempting to restart the reactor later that morning. During the attempted restart, a bypass valve on a recirculating pump opened unexpectedly. Reactor water level initially rose and then fell, and a Reactor Protection System activation and accompanying shutdown occurred.
