APPENDIX A NOTICE OF VIOLATION Duke Power Company Docket No. 50-369 McGuire 1 License No. NPF-9 As a result of the inspection conducted on February 22 - March 8,1982, and in accordance with the NRC Enforcement Policy, 47 FR 9987 (March 9,1982), the following violations were identified.
Technical Specification 3.8.2.3 requires four dc channels to be operable and energized with each channel consisting of a 125 Vdc bus, a 125 Vdc battery bank, and a full capacity charger. The action statement allows one battery to be inoperable for a period of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> if the associated bus is energized with an operable battery via operable tie breakers within two hours.
In addition, Technical Specification 6.8.1(a) and (c) requires procedures to be implemented covering surveillance and test activities of safety-related equipment and procedures listed in Appendix A of Regulatory Guide 1.33.
Contrary to the above, Technical Specifications 3.8.2.3 and 6.8.1(a) and (c) were not followed in that:
a.
On November 13,1981 cell 16 of battery EVCB specific gravity was found to be 1.194 and thus below Technical Specification (TS) 3.8.2.3 limit of 1.195 for operability.
Battery EVCB remained in service for more than eight hours.
During this time, battery EVCA was on equalizing charge and thus wa. inoperable.
b.
Instrument and Electrical procedure IP/0/A/3061/01, by which the battery specific gravity was tested, requires that the shift supervisor be notified if a parameter is below TS limits; however, on November 13 the shift supervisor was not notified of the low specific gravity.
c.
Station Directive 2.8.1 requires a complete investigation of all incidents.
The licensee's investigation of Licensee Event keport No.81-181, which reported the inoperability of battery EVCB on November 14-20, 1981, was not complete enough to detect that the battery was also not operable on November 13 and that documentation of events was not complete.
This is a Severity Level IV Violation (Supplement I.E.).
Pursuant to the provisions of 10 CFR 2.201, you are hereby required to submit to this office within thirty days of the date of this Notice, a written statement or explanation in reply, including:
(1) admission or denial of the alleged viola-tion; (2) the reasons for the violation if admitted; (3) the corrective steps 8207010450 820621 PDR ADOCK C5000369 0
