'Mr. J.G. Keppler, Regional Director Office of Inspection and Enforcement United States Nuclear Regulatory Commission Region III 799 Roosevelt Road Glen Ellyn, IL 60137 Operating License DPR-74 Docket No. 50-316
Dear Mr. Keppler:
On June 16, 1978, we informed NRC Region III verbally and in writing of a violation of the Unit 2 Appendix A Technical Specification Section 3.8.1.lb wherein both emergency diesel generators were inadvertently removed from service during maintenance.
Our investigation into this event is completed and this report is submitted as required by Appendix
(
A Technical Specific,ation Section 6.9.1.8.
We have discussed this serious matter with management of the American Electric Power Service Corporation and together formulated the " Corrective Actions Taken to Prevent Recurrence "
I believe these actions will go a long way towards not only preventing recurrence of this event on the emergency diesel generators, but will also prevent similar incidents from occurring on other safety-related equipment.
The American Electric Power Service Corporation management was at the plant on May 3-4, 1978, to discuss the urgent need to reduce the number of Licensee Event Reports.
At that time we jointly came up with several action items which are being followed through to stem potential problems at the source.
Although this recent incident is particularly disturbing, we in management are taking positive steps to enhance the quality of our operations and the support of the plant by the American Electric Power Service Corporation.
In addition to the corrective actions stated in the attached Licensee Event Report, we will review our current practice of training the plant operating and maintenance staff fnr work of this type and will augment retraining and requalification as necessary.
Sincerely, d
