DCP 95-017 FS99-013 e Surry Monthly Operating Report No. 99-03 Page 10 of 18 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR:

March 1999 Design Change Package (Safety Evaluation 98-050) 04/24/98 Design Change Package 95-017, "Emergency Diesel Generator (EDG) SV Relay Replacement/Surry/Units 1 & 2", replaced the existing "low ruggedness" EDG Field Flash Cut-Off Relays with new relays recommended by Engine Systems, Inc. to reduce contact chattering.

The new relays meet Virginia Power's seismic requirements.

UFSAR Change Request (Safety Evaluation 99-019) 03/25/99 This UFSAR Change documents the use of ASME Boiler and Pressure Vessel Code, Section Ill, Appendix F, "Rules for Evaluation of Service Loadings with Level D Service Limits", for evaluating isolated water filled containment penetrations that are potentially susceptible to over-pressurization during a Design Basis Accident.

O-ECM-1509-03 LDS-SPS1/2 e PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR:

March 1999 Electrical Corrective Maintenance (Safety Evaluation 99-014) Surry Monthly Operating Report No. 99-03 Page 11 of 18 03/11/99 Electrical Corrective Maintenance Procedure, O-ECM-1509-03, "VOTES MOV Testing for Quarter Turn Valves", was revised to invoke administrative controls on the Service Water (SW) Motor Operated Valves (MOV) when one is taken out of service for MOV testing. This will maintain the capability to isolate the non-essential SW flowpaths affected by the inoperable valve. Vendor Procedure (Safety Evaluation 99-016) 03/17/99 Vendor Procedure, LDS-SPS1/2, "Instructions for Valve Acoustic Leak Monitoring", was approved so that vendor technicians can perform leak monitoring on various secondary valves and traps using non-intrusive equipment provided by Leak Detection Services, Inc. while Units 1 and 2 are in normal operation at or near full power.
