Recent solenoid-operated valve experiences involving maintenance and testing deficiencies
Description
The paper presents recent solenoid operated valve operating experience. It describes common-mode failures at the Salem Unit 2 and Peach Bottom Units 2 and 3 plants. At the Salem plant, a catastrophic failure of turbine equipment resulted in an outage of about 6 months. The Peach Bottom event involved repetitive failures of safety systems with a shorter outage. The lessons learned from both events are that prudent preventive maintenance and surveillance testing are needed to enhance safe economic plant operation
