Attachment I Response to Appendix A Violation As a result of the inspection conducted during the period of April 25 through May 3, 1988 and in accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR 2, Appendix C (Enforcement Policy 1988) the following violation was identified.
10 CFR 50, Appendix B, Section V states that
.... Activities
"
affecting quality shall be prescribed by Jocumented instruction, procedures, or drawings of a type appropriate to the circumstances and shall be accomplished in accordance, with these instructions, procedures, or drawings.
Instructions,
,
procedures, or drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished."
Contrary to the above, on April 25, 1988 licensee personnel were observed surfacing (lapping) the
"D" emergency diesel generator crankshaft main and connecting rod bearing journals without documented instructions to establish proper lapping material, lapping procedures, and acceptance criteria.
As a consequence newly installed bearings were found with substantial residual contaminating abrasive lapping cea. pound left in the bearings.
This is a Severity Level IV Violation (Supplement II).
Response:
We are in the process of obtaining instructions from the Diesel Generator manufacturer, Colt Industries, for performing surfacing (lapping) of crankshaft main and connecting rod bearing journals.
This information will be included in the appropriate procedures.
This information will include detailed instructions for the proper methods, materials and acceptance criteria to be used during the lapping process for both the Unit 1 and Unit 2 Emergency Diesel Generators.
t In response to the violation, the contaminated bearings have been disassembled, reeleaned, and inspected.
The Unit 2 personnel involved have been given training in the proper methods to be used during the lapping process.

- In addition, Unit'l has been evaluated for this condition and was found to be exempt.
No lapping has been performed to date.
Future lapping will be performed in accordance with the revised procedure.
We expect all the action to be completed by December, 1988.
We expect no lapping of Diesel Generator bearings prior to that date.
