Subject:
Virgil C. Summer Nuclear Station Docket No. 50/395 Operating License No. NPF-12 Technical Specification Surveillance Requirement' Change
Dear Mr. Denton:
South Carolina Electric and Gas Company (SCE&G) hereby requests that items (b) and (c) of the Virgil'C. Summer Nuclear Station Technical Specification Surveillance Requirement 4.7.4, "Ser-vice Water System," be, transferred to' Surveillance Requirement 4.6.2.3, item'(b), " Reactor Building Cooling - System," (see
. Attachment 1).
The subject' items involve the surveillance of_a portion of the
' Service Water System that' supports only the Reactor Building Cooling Units (RBCU)(see FSAR Figures 9.2-2-and 9.2-3).
This1 portion of the system is actuated upon the receipt of a Cafety Injection signal to supply cooling water to the RBCUs:at a boosted pressure.- Because~of the present_ Technical Specifica-tion requirements, a potential component failure in the portion of the system.that is dedicated to the RBCUs necessitates declaring the entire Service Water System inoperable.
It is the opinion of SCE&G that items (b) and (c) of Technical
. Specification ~4.7.4, are more appropriately addressed under Specification 4.6.2.3 because.the intent of the Specification is~to ensure reliable operation of the RBCUs.
SCE&G has also determined that a finding of no significant hazard is justified (see Attachment 2).
