Dear Mr. Gianbusso:
N O
FAILURE OF NON-CLASS I (SEISMIC) EQUIPMENT NO. 1 AND 2. UNITS.
SALEM NUCLEAR GENERATING' STATION In reply to your letter of September 2'6, 1972, we have reviewed the design of Salem Nuclear Generating Station to determine whether the failure of non-Claca I (seismic) equipment could adversely affect the performance of safety-related equipment.
As suggested, particular attention was given to the postulated failure of the circulating water and fire.
protection systems.
The p,op ih411.ty of impairment of s?.fety-o related systems from the f ailure of non-Class I sys-tems in the turbine bhilding area is non-exfstent.
This area does not contain any safeguard ~ operating systems.
A circulating water line failure, such as occurred at Quad-Cities Unit 1,could possibly flood the basement of the turbine building.
However, this would not affect safeguards equipment which is loca-ted in the nuclear areas.
The buildin6 structures.

Our analysis of failures in the nuclear-area shows no indication of adverse effects to safe-Ng guard systems.

failures resulting in liquid releases in other I
enclosed nuclear areas due to location of-equipment, control pancis, redundent control systems and totally enclosed motors.
Our study 'did, howev'er, uncover some ques-tionabic areas including a ventilation system control' panel and some open case motors.
As,a result, we will relocate the panel and provide shields to assure that no adverse effects will* result due'to impinge-ment of water.
This work will be accompli'shed in the near future consistent with-other construction activities in the affected work areas.
Very truly yours, F.
