APR 2 2 1982 Docket Nos: 50-361 and 50-362 O

'-o APPLICANTS: Southern California Edison Company San Diego Gas and Electric Company City of Anaheim, California City of Riverside, California FACItITY:

San Onofre Nuclear Generating Station, Units 2 and 3

SUMMARY

OF MEETING TO DISCUSS CONTAINMENT PURGE VENT STACK MONITORS On April 20, 1982, members of the NRC staff met with SCE representatives in Bethesda, Maryland to discuss the addition of containment purge vent stack monitors to San Onofre 2 and 3. Attendees at the meeting are given in. Material presented at the meeting is given in Enclosure 2, which includes a schematic of the monitor and proposed modifications to the FSAR and technical specifications which would be made when the monitor is installed.

At the meeting, SCE indicated that the projected procurement schedule would allow the containment purge vent stack monitor to he installed at San Onofre 2 during the first refueling outage (estimated by SCE to be June, 1983).

This schedule will comply with condition 2.C.17 of the San Onofre 2 license.

SCE also indicated that installation of a purge vent stack monitor could not be acco"'olished prior to criticality of San Onofre 3 (estimated by SCE to be January 1983) due to procurement lead time constraints.

SCE suggested that a more realistic schedule for Unit 3 would be installation during the first refueling outage.

SCE stated that the interim monitoring scheme currently being used at Unit 2 could also be used at Unit 3 prior to the first refueling.

The initial CHANNEL CALIBRATION shall be performed using one or more of the reference standards certified by the National Bureau of Standards or using standards that have been obtained from suppliers that participate in measurement assurance activities with NBS. These standards shall permit calibrating the system over its intended range of energy and measurement range. For subsequent CHANNEL CALIBRATION, sources that have been related to the initial calibration shall be used.

(4) The CHANNEL CALIBRATION shall include the use of standard gas samples containing a nominal:

1. One volume percent hydrogen, balance nitrogen, and
