i ENCIDSURE 1 i
Boston Edison Company Docket No. 50 293 Pilgrim Nuclear Power Station License No. DPR-35 i
During an NRC inspection conducted on November 24,1992 through December 31,1992, a violation of NRC requirements was identified. in accordance with the
- General Statement of i
Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1991), the violation is listed below:
Technical Specification 6.8.A requires the proper implementation of procedures recommended in Appendix A of USNRC Regulatory Guide 1.33. Appendix A Section 4 recommends establishment of procedures for startup, operation, and shutdown of safety related systems including the Reactor Protective System (RPS). Procedure 3.M.2-7.6, "NUMAC Log Radiation Monitor Setpoint Change Procedure", provides instruction for the adjustment of protective instrument setpoints associated with the RPS system.
Contrary to the above, on two occasions, the licensee failed to properly implement procedure 3.M.2-7.6 in that technicians established incorrect RPS protective setpoints and management reviews failed to identify the associated discrepancies. Specifically, on December 20,1992, following an automatic reactor trip (which resulted from incorrectly established RPS setpoints) technicians failed to reset the MSL high radiation alarm setpoints as required by procedure 3.M.2-7.6. Further, the required management review of the completed procedure failed to identify the discrepancies.
Additionally, on December 23, 1992, following reactor startup, procedurally-specified review of the setpoint changes again failed to identify the incorrect as found MSL high radiation alarm setpoints. During the period of time between December 20-23,1992, while the MSL trip setpoints had been correctly established, the above licensee failures resulted in the MSL high radiation alarms being unavailable to perform their intended function.
This is a Severity Level IV violation (Supplement IV).
