(TGEDIU JUL 2 3 1982 Docket No. 50-285 Mr. W. C. Jones Division Manager, Production Operations <

Omaha Public Power District 1623 Harney Street Omaha, Nebraska 68102

SUBJECT:

APPENDIX J CONTAINMENT LEAK TESTING REVIEW We have cor pleted our Appendix J Containnent Leak Testing Review in response to your submittals dated September 10, 1975, March 30, 1977, and May 15, 1980. Our Safety Evaluation Report, which is enclosed, identifies three open items as follows:

(1) OPPD's correlation to extrapolate leakage rates at 5 psig to 60 psig for containment airlocks is not sufficiently conservative, (2) The valve or valves associated with penetration M-3 should be testad in accordance with Appendix J. and (3) The valve or valves associated with penetration M-44 should be tested in accordance with Appendix J.

Regarding open item 1, we do not believe that your correlation to extrapo-late leakage rates at 5 psig to 60 psig for containment airlocks is suffi-cien':ly conservative. The basis for not approving this correlation can be found on page 8 of the enclosed NRC contractor report. He agree with our contractor on this, and the method contained in Appendix A of the enclosed contractor report is one method that is acceptable to us.

Regarding open items 2 and 3, we concluded that you did not provide suffi-cient justification for not testing the valves associated with these pene- -

trations in accordance with Appendix J, thus we conclude at this time that they should be tested.
