Chance 4 of the IST Plan) in Response to NRR Safety Evaluation dated Aucust 19. 1992 Relief Request 2.1.6-Provisional relief was granted provided the pump vibration testing program complies with all the vibration testing requirements of ASME OM-6. The relief request was revised to include the given provision for compliance with ASME OM-6, for the granting of the relief.

Relief Requests 2.1.7, 2.1.8 and 2.1.9-Interim relief for one year was granted for these three requests, until flow instrumentation could be installed on the emergency diesel fuel oil pumps or the testing methods could be evaluated. The flow instrumentation was installed during the past refueling outage and these relief requests are withdrawn. It is important to note that a

( Licensee Event Report was written prior to the last submittal of these relief requests, to document the identified non-compliance with applicable code requirements.

Relief Request 3.1.60-This relief request was granted per NRC Generic Letter 89-04.

Relief Request 3.1.61-Provisional relief was granted, provided the subject valves were identified in the IST plan as having a safety function in both the j open and closed directions, and declares both valves in the pair as ~

inoperable if a pair fails the backflow testing. The IST Plan was revised according to the requirements of this provision.

Relief Request 3.1.62-Relief was denied and a revised relief request with additional justification was submitted to the NRC on November 17, 1992, via Entergy Operations, Inc. letter no. W3F1-92-0446. The NRC issued a safety evaluation on January 11, 1993, and concluded that the licensee proposal was in compliance with a later edition of the Code, and as such was acceptable ano no relief was required.

This relief request has been expanded into three separate relief requests; 3.1.65, 3.1.75 and 3.1.76. Additional justification has been added to the basis for relief, and approved relief requests 3.1.16, 3.1.18 and 3.1.71 are referenced.
