Gentlemen:

SUBJECT:

Extension of Completion Date for Changing Abnormal Operating Procedures (AOPs) and Emergency Operating Procedures (E0Ps) to Resolve Containment Penetration M-3 Potential Leak Path Issue In Reference 2, Omaha Public Power District (0 PPD) notified the NRC that containment penetration M-3 was outside the design basis specified in a Safety Evaluation Report which allowed exclusion from Type C testing required by 10 CFR 50 Appendix J. One of the commitments OPPD made to resolve this issue was to change the appropriate A0Ps and E0Ps by May 15, 1991. However, it has been determined that additional engineering analyses must be performed in support of the 10 CFR 50.59 safe +y evaluation before the A0P/E0P changes can be completed, i

These additional analyses include an evaluation by ABB Combustion Engineering l of the impact of the proposed changes on the loss-of-Coolant Accident (LOCA) analysis. OPPD anticipates that the additional engineering analyses will be completed by May 31, 1991. Therefore, OPPD must extend the completior, date to July 15, 1991 to incorperate results from the analyses and complete the verification, validation and procedure issuance processes.

I l If you should have any questions, please contact me.

1 Sincerely,

b. N ?&
