Dear Sir:

Three Mile Island Nuclear Station Unit 1 (TMI-1)

Operating License No. DPR- 0 Docket No. 50 .

Fire Proteethu In response to Staff Position F3 transmitted to Met-Ed in your letter of April 17, 1978, a ecI: titment to detemine if any safety-related cables are in the vicinity of the RC pump motor oil collection system was made in our GQL 1068 (June 12, 1978).

A study has been ec=pleted, and the only safety-related circuits in the RC pump area are frem Reactor Coolant Pump Power Monitor Inputs and RC temperature elements RChA-TE2, RChA-TE3, RCh3-TE2, and RChB-TE3 Sincerely,
