Commonwealth Edison NRC Docket Nos. 50-295/304 ATTAtHMENT A Contrary to Technical Specification 3.15.2.c, on March 12, 1979, with the IB diesel generator out of service, the cross tie breaker from Unit 2 auxiliary transformer to Unit 1 ESF buses was taken out of service, thereby making reserve offsite power un-available for Unit 1. Corrective Action taken and the Results Achieved: As noted in the inspection report, this item had been reported by the licensee as Licensee Event Report 50-295/79-16. Corrective action consisted of reinstruction of shift personnel as well as a change to Periodic Test Procedure PT-14, " Inoperable and Required Redundant Equipment Surveillance." The procedure change adds three reviews in addition to that presently performed by the licensed Shift Engineer. The licensed Unit Nuclear Station Operator and licensed Shift Foreman now also review the applicable Technical Specification sections and sign the PT-14 surveillance logsheet. Following these reviews, the licensed Operating Engineer is notified, thus providing a third additional review. Corrective Action to be taken to Avoid Further Noncompliance: To further insure that Technical Specification 3.15, Auxiliary Electric Power System, is not violated, the licensee has reviewed the current surveillance procedures for this area and is in the process of consolidating the surveillances to more clearly address all the requirements of Section 3.15. At present, the routine surveillances on the auxiliary electric power system are recorded on several documents. Con-solidating these separate requirements into one surveillance procedure will clarify the status of the total auxiliary electric power system to the shift operators and further insure that all essential service features bases are aligned to their proper power sources. Date of Full Compliance: The licensse is in compliance at the present time. The revised surveillance procedure discusred above is being formulated and will be bnplemented by July 1, 1979. / 001 42O L/1 _. _ _.}}
