SUMMARY

OF MEETING TO DISCUSS CONTROL ROOM PRESSURIZATION TEST On June 24, 1982, members of the NRC staff met with the licensees in Bethesda, Maryland, to discuss the above subject. Attendees at the meeting are given in Enclosur'e 1. Material presented at the meeting by the licensees is given in Enclosure 2.

At the meeting the licensees indicated that they would, in the near future, request a three month extension of the requirement for com pletion of the control room pressurization tests given in condition 2.C(8) of the San Onofre Unif2 Operating License, NPF-10. The reason for the request was an unantfeipated delay in procurement of the fan motors required to acheive the desired pressure in the control room.

The licensees stated that the dampers have been procurred and installed, thereby resulting in partial upgrading of the system.
