' APPENDIX A NOTICE OF VIOLATION Maine Yankee Atomic Power Company Docket No. 50-309 Based on the results of an NRC inspection conducted from June 2-July 2,1980, it appears that one of your activities was not conducted in full compli-ance with the conditions of your NRC license as indicated below. This is an infraction.
Technical Specification 3.6.8.2 states in part that, "B.
The following equip-ment must be operable whenever the reactor is in a power operation condition....
2.
Two operable and redundant ECCS trains...."
Exception No.1 states in part that, "If any of the pumps specified becomes inoperable continued power opera-tion is permitted for a maximum of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> provided the pump performing the same function in the other train and the diesel generator in the other train are operable.
In this situation the operable component and its diesel genera-tor shall be tested within two hours after discovery of the outage."
Contrary to the above, the A Secondary Component Conling Pump (P10A), was taken out of service on June 27, 1980, to replace a motor-end bearing, and was returned to service at 4:00 p.m. on June 28, 1980, without testing the B diesel generator.
(Since Secondary Component Cooling (SCC) supplies both diesel generator coolers, loss of either SCC Pump reduces safeguards to a 5 ingle train).
