l APPENDIX A NOTICE OF VIOLATION Philadelphia Electric Company Docket No. 50-352 Limerick Generating Station, Unit 1 License No. CPPR-106 During the January 11-29, 1982 inspection, and in accordance with the Interim Enforcement Policy, 45FR66754 (October 7,1980), the following violations were identified:
A.
10 CFR 50.55a requires that Class 1 valves comply with the ASME Draft Code for Pumps and Valves (DCPV), which specifies in Section 314.1.6 that repair welding procedures be qualified in accordance with ASME Code Section IX.
ASME Code Section IX, Paragraph V-6 requires welding procedure requalifi-cation if there is a change in the heat treating temperature. The repair welding procedure, QAP-490, dated May 7,1971, and Procedure Oualification Record QAP-49D, dated October 26, 1971, limit post-weld heat treatment tem-peratures to 11000-13000 (Fahrenheit).
Further, DCPV Section 314 specifies that nondestructive tests must be performed after any heat treatment.
Contrary to the above, from December 20, 1971 to February 12, 1972, Class 1 Main Steam Isolation Valve B21F022D, Serial No. 3-683, was repair welded, radiographed, and post-weld heat treated / tempered at 13400F.
This is a Severity Level IV Violation (Supplement II).
B.
10 CFR 50 Appendix B Criterion V requires that activities affecting quality be performed in accordance with procedures.
Project Special Provision Notice PSP G-6.1, Revision 3, Paragraph 3.1.5, specifies that inspection hold points are mandatory and work shall not proceed to a point where work is no longer inspectable.
Quality Control Instruction H-2.00, Paragraph 2.4.a.1, requires that minimum preheat and interpass temperatures be verified for full penetration groove welds,as a hold point inspection.
Contrary to the above, reviews on January 21, 1982, disclosed that the pre-heat and interpass temperature hold point inspections for full penetration groove welds listed on Quality Control Inspection Record C-1415-W-1 had not been performed, and the welds had been completed without them.
This is a Severity Level VI Violation (Supplement II).
Pursuant to 10 CFR 2.201, Philadelphia Electric Company is hereby required to sub-mit to this office, within 30 days of the date of this Notice, a written reply, including:
