. Mr. Darrell G.'Eisenhut', Acting Director Division of Operating Reactors Office of-Nuclear Reactor Regulation U.S.-Nuclear. Regulatory Commission Washington, D.C. 20555-Gentlemen:

~ LWR PRIMARY COOLANT SYSTEM PRESSURE ISOLATION VALVES NO. 1 UNIT SALEM GENERATING STATION In r.jlv to your letter of February 23, 1980, we submit the folic. .g information:

Item 1

'During-the In-Service Test (IST) program review with the NRC on January 30-31, 1980, the Event V isolation valve configurations

>

at Salem were identified. _There are five (5) basic configura-tions with_ twenty (20) paths from the High Press'ure Reactor Coolant System (RCS) to the Low Pressure Injection System (LPIS) piping. These are shown in the attached Figures 1-5. Although the configuration _in Figure 5 does not conform to the descrip-tion in the' referenced letter, it was discussed at the IST pro-l gram review and specifically addressed by the'NRC as valves per-forming a pressure isolation function.

-Item 2 Currently, there is'no specific surveillance program to insure these valves are not leaking. All the valves are periodically exercise ~d in accordance-with the IST program to' insure oper-ability.- Leakage through the pressure isolation paths would be

' indicated by an increase'in RCS make-up.

-

A review of completed: Surveillance Procedures and Equipment History Files reveals no record of loss of integrity for the b

- valves under discussion.. ///
