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. Revision 1 will mechanically block the failed fan's flow switch, clear the locked-in Main control Room annunciator, and restore the alarm function from the running fan.

UFSAR Change Request (Safety Evaluation 98-091) 99/03/98 UFSAR Change Request FS.98-014 contains a list of several items that needed to be corrected or enhanced in the UFSAR sections that discuss Surry's Service Water System.

These changes were needed as a result of the Integrated Configuration Management Project and consist of editorial and technical changes/corrections.

Temporary Modification (Safety Evaluation 98-092) 09/10/98 Temporary Modification S1-98-016 will be used to inject well water in the Emergency Service Water Pump discharge pipe in an effort to establish low salinity levels at the pump impeller. A salinity meter will be placed in the pump suction near the impeller. This activity will be accomplished while the pump is out of service for scheduled cleaning while in a Technical Specification seven day clock.
