Mr. Steven A. Varga, Director Project Directorate #3 Division of PWR Licensing Gentlemen:
FIRE PROTECTION -
10 CFR APPENDIX R WITHDRAWAL OF EXEMPTION REQUEST SALEM GENERATING STATION UNIT NOS. 1 AND 2 We have performed additional reviews of the 10 CFR 50 Appendix R exemption request related to a three hour fire barrier between Control Rooms based on NRC concerns.
Based on this review, PSE&G has concluded that this exemption request is no longer required.
A review of the staffing available and the alternate *shutdown procedures have demonstrated that sufficient personnel, even at minimum Technical Specification Requirements, are available to perform simultaneous alterriate shutdown of both Salem Unit Nos. 1 and 2.
Timeline studies show that both the units can be brought to hot standby with the available manpower.
Previously, PSE&G had stated that simultaneous shutdowns could not be performed.
The current position resulted from modifications performed to the diesel starting circuitry as a result of NRC Inspection Report.
83-37.
The above information was presented to NRC staff during a meeting held on August 21, 1986.
As a result of the meeting, information is also being provided related to the auxiliary shutdown-panel (panel 213) located at elevation 84 of the Auxiliary Building.
Panel 213 was originally designed for control room evacuation without consideration of a postulated control room fire.
In order to provide the necessary indications to the operator, Appendix R related instruments have been installed on this panel.
These circuits* have been designed to be totally separate from *existing instrumentaion.
Separate and independent instruments, power supplies, signal conditioning equipment and indicators have been provided which are independent
~f the fire area of concern.

Mr. Steven A. Varga 2
8-29-86 Panel 213, which is located in fire area 1FA-AB-84B, is protected by redundant detection and suppression systems as described in PSE&G letter NLR-N86005, dat:,E:ld January 17, 1986. __ Additionally, panel 213 is completely wrapped in FS-195 except for handles and latches. (see attached photograph).
This provides the equivalent of a one hour rated f ir~-barrier for the panel thus ensuring the integrity and operability' of the equipment in the panel in the event of a fire in the area of the panel.
