e Surry Monthly Operating Report No. 98-08 Page 10 of 17 FACILITY CHANGES THAT DID Nor REQUIRE NRC APPROVAL MONTHNEAR: August, 1998 Design Change Package (Safety Evaluation 94-129) 08/19/98 DCP 92-052, "Station Black-out Diesel Installation," installed the Alternate Alternating Current (MC) diesel generator and its associated systems as an alternate AC power source for Station Black-out (SBO) for Units 1 & 2.
UFSAR Change Request 08/13/98 (Safety Evaluation 98-033, Rev. 1)
Safety Evaluation 98-033, Rev.1, evaluated the ability of the Recirculation Spray RS subsystems to meet the containment analysis acceptance criteria considering the flow diverted from the spray headers by the vents and drains while crediting expected RS subsystem flows. This safety evaluation assessed the effect of this change upon existing accident analyses. UFSAR Change Requests FS 98-08 and FS98-019 were prepared to incorporate the evaluation into the affected UFSAR sections to account for the diverted flow impact until the flow through the vents and drains is reduced and Outside RS minimum flow is restored to the value used in the core uprate analysis.
Temporary Modification (Safety Evaluation 98-077) 08/06/98 Temporary Modification S 1-98-011 was used to remove the logic section of the Main Control Room Ventilation System Panel (VSP) Annunciator Panel and relocate the logic panel to a temporary support for work associated with a design change package.
Temporary Modification (Safety Evaluation 98-078) 08/06/98 Temporary Modification S2-98-004 was used to lift a lead and install a temporary cooling fan on the pressurizer proportional heater panel located in the upper cable vault. The temporary modification will be used to ensure that pressurizer proportional heaters do not reduce to a minimum output insufficient to maintain RCS pressure due to failure of one or both internal panel fans.
UFSAR Change Request (Safety Evaluation 98-079) 08/13/98 UFSAR Change Request FS98-019 contains a list of several items that needed to be corrected or enhance in the UFSAR sections that discuss Surry's Recirculation Spray System.
These changes were needed as a result of the Integrated Configuration Management Project and consist of grammatical and system description clarifications.
UFSAR Change Request (Safety Evaluation 98-080) 08/13/98 UFSAR Change Request FS98-021 ensures that the appropriate water holdup effects enumerated in the supporting calculation are incorporated into the net positive suction head analysis basis for the inside and outside recirculation spray, and low head safety injection pumps.

UFSAR Change Request FS98-019 contains a list of several items that needed to be co;;ected or enhance in the UFSAR sections that discuss Surry's Safety Injection System as a result of the Integrated Configuration Management Project and consist of grammatical and system description clarifications.
Safety Evaluation 08/13/98 (Safety Evaluation 98-083)
Safety Evaluation 98-083 assessed the inoperability of area radiation monitors for being out of service for greater than thirty days to ensure that there were no unreviewed safety questions. The major issues considered were the capability to detect reactor coolant system leakage inside containment, to monitor containment radiation following a loss of coolant accident, and to mitigate the consequences of a fuel handling accident inside containment.
Temporary Modification (Safety Evaluation 98-085) 08/13/98 Temporary Modification S2-98-005 was to replace an alleyway subsurface drain pump with a history of tripping on thermal overload due to binding from sand buildup in the pump. A different design of pump was used to replace the original to eliminate the effects of the sand.
Temporary Modification (Safety Evaluation 98-090) 08/26/98 Temporary Modification S2-98-006 was required to replace a failed relay in a consequence limiting safeguards backup circuit which included jumpers to maintain circuit continuity and defeating the train "B" HI-CLS trip signal to train "B" safety injection (SI). All work will be performed on train "B" while train "A" will remain unaffected. Train "B" HI-CLS will provide all its output signals except for the blocked SI signal. Train "B" of SI will have all its automatic and manual trip signals except the HI-CLS trip at all times.

e PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: August, 1998 Calibration and Operating Procedures (Safety Evaluation 98-063 Rev. 1)
Surry Monthly Operating Report No. 98-08 Page 12 of 17 08/13/98 Calibration Procedure 1-CAL-153, "Stripper Feed Steam Heater Outlet (T-BR-103A)," and "Operating Procedures 1/2-0P-RC-012, "RDS Degas Operation," and OP-10.1.1, "Placing the Gas Stripper System in Operation," were revised to procedurally control a temporary modification to enable the operation of a non-outage gas stripper with one stripper feed steam heater and the option to place the tagged-out heater in operation for outage degassing.
Temporary Operating Procedure (Safety Evaluation 98-088) 08/20/98 The safety evaluation and Temporary Operating Procedure, 2-TOP-RC-4088, "Securing pressurizer Proportional Heaters," were used to control and evaluate the effects of cycling the pressurizer proportional heaters off for an extended period of time.
The heaters were needed to be off for the repair/replacement of the proportionate heater cabinet fan while on line. The evaluation assessed the capability of the remaining heaters to maintain RCS pressure with the proportional heaters tagged out.
