Of fice of Inspection and Enforcement U.S. Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, Illinois 60137 RE:
Perry Nuclear Power Plant Docket Nos. 50-440; 50-441 HPCS Interf aces to the Suppression Pool Clean-up System [RDC 99(84)]
Dear Mr. Keppler:
This letter serves as the interim report pursuant to 10CFR50.55(e) on the deficiencies concerning design of the High Pressure Core Spray (HPCS) interf aces to the Suppression Pool Clesn-up System.
Mr. P. R. Pelke of your office was notified on February 16, 1984, by Mr. B. D. Walrath of The Cleveland Electric Illuminating Company (CEI) that this problem was being evaluated. This discrepancy was identified during a safety system functional capability review being performed for CEI by GDS Associates.
This report contains a description of the deficiency, planned corrective action and the date for filing of the next report on this subject.
Description of Deficiency The Suppression Pool Clean-up System takes suction from the high pressure core spray suction via suppression pool valve E22-F015.
The HPCS System will automatically start upon a Level 2 Loss of Coolant Accident (LOCA) signal but the clean-up pump suction valves close on a Level 1 LOCA signal per e'.ementary diagram B-208-065.
Unless the clean-up pump suction valves close, HPCS could be inoperative due to opposing pump suction from the clean-up pump.
