i Question 1 i

1 Provido a copy of the document from the Inservice Testing (IST) Program for Umerick Generating Station (LGS) Units 1 and 2, that shows the minimum flow requirement and the surveillance test frequency fcr the Standby Liquid Control System (SLCS) pumps

- surveillance testing.

Response 1 j The following excerpts from the LGS IST Program are provided herein. l l

- LGS Unit 1 and Common, Specification ML-008, Revision 4, dated 12/29/94, "lST Table - Pumps", page no. 4

- ASME Boiler and Pressure Vessel Code, Section XI, " Inservice Testing of Pumps,1986 Edition, IWP-3200-lWP-3400, page no. 247 l

- LGS Test Procedure No. ST-6-048-230-1, Revision 09, "SLC Pump, Valve and Flow Test", page nos.1,16 and 44 Question 2

! Provide a statement regarding the number of SLCS pumps at LGS Units 1 and 2. l Response 2 The SLCS consists of three redundant pumps and injection vah'e loops per unit. Only one of the three SLCS pumps is needed to meet the SLCS design basis described in LGS Updated Final Safety Analysis Report (UFSAR) Section 9.3.5.1. Two pumps are required to meet the requirements of the Anticipated Transients Without Scram .

(ATWS) Rule (10 CFR 50.62), if a pump is found to be inoperable, there is no impact l on the shutdown capability, and reactor operation can continue during repairs. This l ensures that SLCS is a highly reliablo system at LGS Units 1 and 2. l
