During the Nuclear Regulatory Commission (NRC) inspection conducted from January 9 through February 10, 1994, violations of NRC requirements were identified.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violations are listed below:
A.
Technical Specification Section 6.8.1 requires, in part, that procedures shall be established covering the activities recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978. Appendix A of Regulatory Guide 1.33 includes administrative procedures for conduct of modifications to the facility.
Procedure SSP-9.3, PLANT MODIFICATIONS AND DESIGN CONTROL, Revision 6, was established, in part, to control the implementation of plant modifications.
DCN M09505A and WO 93-09179-00 were written in accordance with SSP-9.3 and governed modifications to and testing of the Unit 1 Component Cooling Water System supply valve to the letdown heat exchanger.
Contrary to the above, SSP-9.3 was not adequately established to control- -
^
the implementation of modifications, in that the modification process allowed the Unit 1 Component Cooling Water System supply valve to the letdown heat exchanger to be returned to service prior to completion of the calibration and post modification testing specified in DCN M09505A and WO 93-09179-00.
