In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"
10 CFR" Part 2, Appendix C (1990), the violations are listed below:

B.
Surveillance procedures are implemented in part by surveillance test Procedure 74ST-9SS02, "Post Accident Sampling System Leakage Monitoring."
This procedure requires in step 7.5 verification that "the RDT is available to receive PASS effluents."
This is accomplished by performing steps in Operating Procedure 740P-1SS02, "Operation of the Post Accident Sampling System", in which Step 4.3. 1.2 states, "for RDT return, request Control Room open/check open 1-CHUV-715. "
Contrary to the ab'ove, on April 22, 1990, while performing step 7.5 of 74ST-9SS02, valve 1-CHUV-715 in Unit 1 was not opened and subsequently resulted in over-pressurizing part of the Post Accident Sampling System.
