e-Thomes J. Martin Public Service Electric and Gas Company 80 Park Plaza Newark, N.J. 07101 201/4304316 Vic) President Engineering and Construction April 14, 1983 Mr.
R. C. Haynes, Administrator U. S. Nuclear Regulatory Commission Office of Inspection and Enforcement Region 1 631 Park Avenue King of Prussia, Pennsylvania 19406
Dear Mr. Haynes:
NRC IE BULLETIN NO. 77-07
" CONTAINMENT ELECTRICAL PENETRATION ASSEMBLIES AT NUCLEAR POWER PLANTS UNDER CONSTRUCTION" HOPE CREEK GENERATING STATION On February 10, 1978, PSE&G submitted a written response to your office concerning the subject Bulletin, which stated in Paragraph 2.0, "After installation, the pressure inside the penetration is to be kept about 15 psig."
By letter dated March 7, 1983, the manufacturer, Westinghouse Electric Corporation, advised us that although the Westinghouse penetrations are designed to operate with zero pressure, periods of zero pressure should not exceed three months.
Accordingly, the last sentence of Paragraph 2.0 of our February 10, 1978 letter is amended to read, "After installation, a positive pressure is to be maintained inside the penetration assen.vlies."
PSE&G intends to continue monitoring the pressure of installed penetrations on a monthly basis to verify seal integrity.
Remedial action will be taken in compliance with the above vendor recommenda-tion for any zero pressure conditions noted.
Very truly yours,
8304250001 830434 gDRADOCK 05000354 PDR
