SUMMARY

OF OPERATING EXPERIENCE MONTHNEAR: March 1999 The following chronological sequence by unit is a summary of operating experiences for this month that required load reductions or resulted in significant non-load related incidents.

UNIT ONE:

03/01/99 0000 Unit starts the month at 100% / 855 MWe.

03/21/99 2320 Removed waterbox "B" from service. Unit at 100% / 830 MWe.

03/23/99 0746 Returned waterbox "B" to service. Unit at 100% / 849 MWe.

03/31/99 2400 Unit finished the month at 100% / 850 MWe.

UNIT TWO:

03/01/99 0000 Unit started the month at 91.5% / 780 MWe. (Began cycle coast-down 02/24/99) 03/31/99 1653 Power lost to MSR control system. Unit at 76% / 765 MWe.

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.

FS99-013 UFSAR Change Request 03/25/99 (Safety Evaluation 99-019)

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.

e Surry Monthly Operating Report No. 99-03 Page 11 of 18 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: March 1999 O-ECM-1509-03 Electrical Corrective Maintenance 03/11/99 (Safety Evaluation 99-014)

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.

LDS-SPS1/2 Vendor Procedure 03/17/99 (Safety Evaluation 99-016)

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.
