As a result of the Integrated Configuration Management Project review, UFSAR Change Request FS99-028 contains corrections and clarifications to the UFSAR sections that discuss Surry's Gaseous Waste Disposal System (GW). They include clarification of component activities, deletion of text describing use of the waste gas catalytic recombiner, and more precise characterization of equipment. These changes are to enhance accuracy and do not affect any GW system or structure, or any of its component's operation or performance.

FS99-035 UFSAR Change Request 09/23/99 (Safety Evaluation 99-087)

As a result of the Integrated Configuration Management Project review, UFSAR Change Request FS99-035 contains corrections and clarifications to the UFSAR sections that discuss Surry's nuclear instrumentation system. They include clarification of component activities, deletion of text associated with the automatic rod withdrawal blocking function, and more precise characterization of equipment. These changes are to enhance accuracy and do not affect any nuclear instrumentation system or structure, or any of its component's operation or performance.

FS99-038 UFSAR Change Request 09/23/99 (Safety Evaluation 99-088)

As a result of the Integrated Configuration Management Project review, UFSAR Change Request FS99-038 contains corrections and clarifications to the UFSAR sections that discuss Surry's feedwater, condensate, condensate polishing, and steam generator blowdown systems. They include clarification to improve readability, changes to reflect previous plant changes, and more precise characterization of equipment. These changes are to enhance accuracy and do not affect any feedwater, condensate, condensate polishing, or steam generator blowdown system or structure, or any of its component's operation or performance.

e Surry Monthly Operating Report No. 99-09 Page 12 of 16 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: September 1999 1-ECM-2403-03 Electrical Corrective Maintenance Procedure 09/14/99 (Safety Evaluation 99-084)

Electrical Corrective Maintenance Procedure 1-ECM-2403-03, "RSS Transformer C Outage with Backfeed of Transfer Bus F" is used to re-position leads, jumpers and relays to support the backfeed lineup of the F Transfer Bus while taking the C Reserve Station Service Transformer out of service. This safety evaluation allows the modification to defeat automatic tripping of selected 4160 volt breakers associated with Transfer Bus F.

1/2-ICM-EP-CAB-002 Instrument Corrective Maintenance Procedures 09/27/99 (Safety Evaluation 99-090)

Instrument Corrective Maintenance Procedures 1/2-ICM-EP-CAB-002, "Placing Failed Channel of 4KV Underfrequency in Trip or Returning to Normal", were written to place a failed channel of 4KV Underfrequency circuitry in Trip in order to meet the requirements of Technical Specifications Table 3.7-1, Item 13 if a channel fails.
