' Washington, D. C. 20555 Ladies and Gentlemen:

VOGTLE ELECTRIC GENERATING PLANT REQUEST TO REVISE TECHNICAL SPECIFICATIONS REVISED RESPONCE TO REQUEST FOR ADDITIONAL INFORMATION By letter dated December 16,1998, SNC responded to a request for additional information (RAl) regarding our' submittal of July 13,1998, LCV-1175. Our submittal of July 13,1998, proposed to revise the Vogtle Electric Generating Plant Unit 1 and Unit 2 Technical Specfications to eliminate periodic response time testing requirements on selected sensors and protection channels. Our response of December 16,1998, to the RAI, contained a typographical error. The table entitled " Process / Function / Reactor Trip / Allocation / Tabic" reported a time of 145 ms for the OTDT (Vary Precs) 7300/NIS String. Instead of 145 ms, the time should have been shown as 140 ms. A corrected copy of the table is attached to this letter. We apologize for any inconvenience that this error may have caused.

Sincerely, J A I B. easl y,J JBB/NJS

f (Note 1) Allocated sensor times not used for these variables. These components will continue to be tested as required.

Allocated sensor times are derived from method (3) section (9) WCAP-13632 rev. 2 (Vendor Engineering Specifications). Tobar, Veritrak, and Barton times were provided on Table 9-1. Rosemount times are from Rosemount manuals 4302 and 4631. The Rosemount response time specifications may also be found in NUREG/CR-5383. Transmitter FMEAs are based upon EPRI report NP-7243 rev 1.

Values for 7300 cards are from tables 4-7 throug5 4-12 of WCAP-14036 rev.1. Cards inst:lled are 4NCil,4NRA,6NLP,4NSA, and 9NAL or older artwork levels. NIS components installed are: Summing and Level Amp (3359C48G01), Isolatioa Amp (6065D75G01), Rate Circuit Assy (3359C41G01), and Bistable Relay Driver Assy (3359C39G01). These were evaluated per NIS FMEA schematic diagram 6t65D99.

SSPS Input and Master iciays are Potter & Jrur .deld Kil series relays. SSPS Slave relays are Potter & Brumfield MDR relays. Values are tabulated from section 4.8 Westinghouse SSPS FMEA.
