APPENDIX A NOTICE OF~ VIOLATION Boston Edison Company M/C Nuclear Docket No. 50-293 Based on tho results of the NRC inspection conducted on May 4-8, 1980, it appears that certain of your activities were not conducted in full compliance with conditions of your Facility License No. DPR-35 as indicated below.
Item A and B are both infractions.
A.
10 CFR 50, Appendix J, Section III.A.l.(a), states that, "During the period between the initiation of the containment inspection and the performance of the type A test, no repairs or. adjustments shall be made so that the con-tainment can be tested in as close to the 'as is' condition as practical."
Contrary to the above, during the type A test, one repair and one adjust-ment to the containment isolation boundary were made without measuring (quantifying) the "as found" leakage.
They are:
1.
Attempted repair (tightening) of a leaking 8 inch pipe flange on the RCIC Turbine exhaust line on May 5,1980.
2.
Made adjustment by closure of valve A0 5033A in the Containment Atmospheric Control System on May 6,1980.
B.
10 CFR 50, Appendix J, Section IV.A, requires that any modification or replacement of a component which is part of the primary reac:or containment boundary be followed by the applicable type leakage rate test.
Paragraph VII.E of PNPS Procedure No. 8.7.1.3, Local Leak Rate Test, states that, "Whenever maintenance is performed on any of the tested valves, seals, or penetrations which affect their leak tight integrity, such valve, seal, or penetration must be retested..."
Contrary to the above, an 8 inch pipe flange on the RCIC Turbine exhaust line, which is part of the primary reactor containment boundary, was disassembled for maintenance on May 2,1980 and not retested.
Leakage from this flange ~ subsequently contributed to the failure of the type A test to meet its acceptance criteria on May 5,1980.
