t APPENDIX B-NOTICE OF DEVIATION Omaha Public Power District Docket: 50-285/87-02 Fort Calhoun Station License: DPR-40 Based on the results of an NRC inspection conducted on January 1-31, 1987, a deviation of your commitments made to the NRC was identified. The deviation consisted of the failure to place all manual containment isolation valves under administrative control. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1986),

the deviation is listed below:

Section 5.9.5 of the Updated Safety Analysis Report states that where a system penetrates containment and the system is inactive during reactor operation, operation of manual isolation valves is under administrative controls. Section 5.9.5 also states that branch line connections between the containment and the outside containment isolation valves are equipped with valves to provide isolation integrity equal to at least that of the main system.

In deviation from the above, manual isolation valves in branch lines between the containment and the outside containment isolation valve were not placed under administrative controls. -The affected branch lines identified by the NRC SRI with manual valves were in the chemical and volume control system (Valves CH-517, CH-518, and CH-535), main steam system (Valves MS-101 and MS-103), low-pressure safety injection system (Valve SI-375), and component cooling water system (Valves AC-1133, AC-1134, AC-857, and AC-858). (285/8702-01)
