A. Rancho Seco Technical Specification 6.8.1.a requires that the applicable procedures recommended in Appendix A of Regulatory Guide 1.33 (November,

, 1972) shall be established.

Section F of Appendix A Regulatory Guide 1.33, " Procedures for Combating emergencies and Other Significant Events," requires procedures for " Loss of Electrical Power (and/or degraded power sources)," " Loss of Flux Indication," and " Acts of Nature.

Contrary to the above requirements, the licensee had not established procedures for loss of 120 VAC, loss of flux indication, and dam failure.

This is a Severity Level IV Violation.

B. Rancho Seco Technical Specification 6.8.1.a requires that the applicable procedures recommended in Appendix A of Regulatory Guide 1.33 (November, 1972) shall be established.

Section H of Appendix A, Regulatory Guide 1.33 recomends that

" Procedures of a type appropriate to the circumstances should be provided to assure that tools, gauges, instruments, controls, and other measuring and testing devices are properly controlled, calibrated, and adjusted at specified periods to maintain accuracy."

Contrary to the above requirement, on April 11, 1986, no written procedures existed specifically addressing crimping tool calibration and control.

This is a Severity Level IV Violation.

C. Technical Specification 3.13.1 requires the Control Room / Technical Support Center (CR/TSC) Emergency Filter System to be operable at all times when containment integrity is required. Technical Specification 4.10 requires a system air flow of 3200 cfm 10% during periodic testing of the Control Room / Technical Support Center Emergency Filtering System to demonstrate that the system is operable.

Contrary to the above requirements, on October 1, 1985, operating airflow rates through the CR/TSC Emergency Filtration System were measured to range from 3581 to 4170 cfm during the entire duration of the 24-minute 870226020S 870206 PDR ADOCK 05000312 O PDR

surveillance test. Furthermore, during actual emergency operation of the B train on December 26, 1985, while containment integrity was required air flow rates ranged from 4071 to 4575 cfm during emergency operation for 8 minutes. No corrective actions were taken to correct the excessive air flow rates after the October 1, 1985, surveillance test.

This is a Severity Level IV Violation.

Pursuant to the provisions of 10 CFR 2.201, the Sacramento Municipal Utility District is required to submit to this office within thirty days of the date of this Notice a written statement or explanation of reply, including: (1) corrective steps which have been taken and the results achieved: (2) corrective steps which will be taken to avoid further items of noncompliance; and, (3) the date when full compliance will be achieved. Consideration may be given to extending your response time for good cause shown.

Prior to the conclusion of the inspection, our inspectors verified that appropriate corrective actions had been defined and implemented for Violations A and B. Consequently, these violations need not be addressed in your response.
