Technical Specifications Change Request - RTD Bypass Elimination 1
Gentlemen:
As requested in your letter dated December 7, 1989, attached is additional informationontheSouthCarolinaElectric&GasCompany(SCE&G) Technical Specifications change request for RTD Bypass Elimination.
Specifically, this proposed amendment supports a plant modification to replace the existing resistance temperature detector (RTD) bypass manifold system with fast response RTDs located in the reactor coolant hot and cold leg piping. SCE&G is proposing this change to eliminate the operating obstacles associated with.
the bypass system such as leakage through valves and flanges and radiation exposure during reactor building maintenance.
The original Technical Specifications change request, submitted July 21, 1989, contains the Westinghouse Letter, " Application for Withholding Proprietary Information from Public Disclosure" (CAW-89-065) and Affidavit CAW-88-131. These documents are required because the change request includes WCAP-12189 which involves information proprietary to Westinghouse Corporation.
Attachment I contains SCE&G's response to the request for additional information. Because Attachment 1 contains detailed infermation pertaining to WCAP-12189, SCE&G requests the NRC to treat the attacned response as part of the original submittal and, as such, to withhold from public disclosure that information which is proprietary to Westinghouse.
I declare that the statements and matters set forth herein are true and correct to the best of my knowledge, information and belief.
