Dear Mr. Farrar:

WGuldemond, Reg.III

SUBJECT:

ZION NUCLEAR POWER STATION UNITS 1 AND 2 - RELIEF FROM FIRST TEN-YEAR INSERVICE INSPECTION AND TESTING REQUIREMENTS By letter dated May 13, 1985, the Comonwealth Edison Company (CECO) submitted Revision 4 to the Inservice Inspection Program for Zion Units 1 and 2 for the first ten-year interval. The revision included requests for relief from certain hydrostatic testing requirements of Subsection IWA-5244(a) of the ASME Boiler and Pressure Yessel Code 1980 Edition through 1981 Winter Addenda.

We have reviewed this submittal and our review has determined that the code requirements for the specified systems are impractical and the granting of the relief is authorized by law and will not endanger life or property or the comon defense and security and is otherwise in the public interest, giving due consideration to the burden upon the license that could result if the requirements were imposed on the facility. Detailed technical assessment is contained in the enclosed Safety Evaluation. Based on our conclusion, pursuant to 10 CFR 50.55a(g)(6)(1), we grant the relief.

Sincerely,

/s/SVarga Steven A. Varga, Chief Operating Reactors Branch #1 Division of Licensing
