| Title | Shut Down Initiated Due to Inoperable Steam Generator Flow Channels |
| Event Description | This 4-hour notification is being made to report that Salem Unit 2 has initiated a manual reactor shutdown in accordance with [Technical Specification] 3.0.3. The shutdown was initiated due to all eight steam generator steam flow channels being declared inoperable at 1500 on 5/12/08. All eight steam flow channels were indicating lower than actual steam flow such that the high steam flow coincident with low steam pressure or low-low Tave would not occur within the allowable values specified in the technical specifications. Salem Unit 2 is currently in Mode 1. Reactor Coolant System Temperature is 551 degrees Fahrenheit with pressure @ 2235 PSIG. Salem Unit 2 has no other shutdown Tech. Spec. action statements in effect. Prior to the initiating event Salem Unit 2 was raising power at 1/2 % per hour after 2R16 refueling outage.
All ECCS and ESF Systems are available. No personnel injuries have occurred as a result of the shutdown. No radiological release due to this event. 21 service water pump is cleared and tagged for strainer replacement. 21A and 23B circulating water pumps are cleared and tagged for maintenance. The licensee notified the NRC Resident Inspector. |
