TECHNICAL SPECIFICATION SHUTDOWN DUE TO LOSS OF RESIDUAL HEAT REMOVAL PUMP
"On September 4, 2016 at 0258 [CDT], Grand Gulf Nuclear Station entered three [Technical Specification] Limiting Conditions for Operations (LCOs) due to residual heat removal pump 'A' (RHR 'A') being declared inoperable.
"LCOs entered:
1) 3.5.1 for one low pressure ECCS injection/spray subsystem,
2) 3.6.1.7 for one RHR containment spray subsystem, and
3) 3.6.2.3 for one RHR suppression pool cooling subsystem.
"Station management has made the decision to shutdown the plant to repair the RHR 'A' pump prior to the end of the 7 day LCO completion time based on troubleshooting and testing performed on the RHR 'A' pump.
"Grand Gulf Nuclear Station initiated plant shutdown required by Tech Spec Actions 3.5.1, 3.6.1.7, and 3.6.2.3, at 0300 CDT on 09/08/2016 due to expected inability to restore RHR 'A' to operable status prior to exceeding the LCO time of 7 days."
The unit is currently at 82 percent power. There are no other systems out of service that would complicate the orderly shutdown to Mode 4.
The licensee will notify the NRC Resident Inspector.
