| Title | 10 CFR 50.59 Evaluation of a Change to an Engineered Safety Features Actuation (ESFAS) Test Procedure |
| Description | The inspectors selected the six operability determinations or functionality evaluations listed below for review based on the risk-significance of the associated components and systems. The inspectors reviewed the technical adequacy of the determinations to ensure that technical specification operability was properly justified and the components or systems remained capable of performing their design functions. To verify whether components or systems were operable, the inspectors compared the operability and design criteria in the appropriate sections of the technical specification and updated final safety analysis report to the licensees evaluations. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. Additionally, the inspectors reviewed a sample of corrective action documents to verify the licensee was identifying and correcting any deficiencies associated with operability evaluations. Documents reviewed are listed in the attachment. Unit 1, Following the 1A DG periodic test on April 18, 2017, a 10 drop per minute lube oil leak from the 1A engine driven lube oil pump was identified, CR 2117628 Unit 2, DG-2A Power-driven Potentiometer pre-position circuit, CR 2116554 Unit 2, Acoustic monitors for the pressurizer safety valves, CR 2125238 Unit 1, Faint abnormal odor on 1 DG control panel A, CR 2132262Unit 1, 1A EDG kilowatts spiked from 900 kw to 7000 kw when jumper was placed in circuit for testing, CR 2118549 Unit 2, Questions on auxiliary shutdown panel supply unit, CR 2124814 b. Findings(Opened) Unresolved item (URI): 10 CFR 50.59 Evaluation of a Change to an Engineered Safety Features Actuation (ESFAS) Test ProcedureIntroduction: The inspectors identified a URI associated with the implementation of a procedure change to the Unit 1 auxiliary shutdown panel (ASP) room air conditioning system. Additional information is needed to determine if a performance deficiency exists.Description: In November 2015, the licensee changed procedure PT/1/A/4200/009, Engineering Safety Features Actuation periodic test (ESFAS), to allow testing of the 1A ASP room air conditioning unit while it was unavailable. A URI was identified because the change verified the ESFAS Sequenced On light was lit, where the previous version of the procedure confirmed the air conditioning unit was running. The licensee did not perform a 50.59 evaluation, and the inspectors determined the change may affect the intent of the surveillance requirement.The licensee has initiated a 50.59 evaluation to determine the impact of the change relative to ESFAS testing requirements. The inspectors will review the completed evaluation to determine if a performance deficiency exists. The licensee documented this issue and background information in their corrective action program as CR 2124814. (URI 05000413/2017002-01, 10 CFR 50.59 Evaluation of a Change to an Engineered Safety Features Actuation (ESFAS) Test Procedure). |
