Oockets:

50-275 50-323 Licenses; DPR-80 DPR-82 During an NRC inspection conducted on September 26 through October 7, with in-office inspection through October 28,

1994, a violation of NRC requirements was identified.

In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"

10 CFR 2, Appendix C, the violation is listed below:

Criterion V of Appendix B to 10 CFR Part 50 requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings of a type appropriate to the circumstances, and shall be accomplished in accordance with these documented instructions, procedures, or drawings.

ID1 requires the documentation of all identified hardware-related or administrative problems relative to nuclear power generation activities, through the initiation of an action request, so that the cause of the problems can be identified and actions developed to ensure the problems do not happen again or to reduce the chance of the problems recurring.

Contrary to the above:

A.

Documented instructions were not appropriate to the circumstances for the resistance temperature detector modification project on Unit 2, in that they did not provide adequate measures for controlling or containing reactor coolant system water that spilled out of the Loop 1

hot leg during machining operations on October 5, 1994, during Refueling Outage 2R6.

(A similar event occurred in Unit 1 during Refueling Outage 1R6).-
