NOTICE OF VIOLATION Docxet No. 50-341 Detroit Edison Company Based on the inspection conducted on July 31 through August 3, 1978, it appears that certain of your activities were in noncompliance with NRC requirements, as noted below.
Items 1 and 2 are infractions, and item 3 is a deficiency.
1.
Contrary to 10 CFR 50, Appendix B, Criterion V and Enrico Fermi Unit 2 QA Manual, QA Procedure No. 9, Rev. 3, Paragraphs 9.1.1 and 9.1.5 on August 2, 1978, the inspector observed the following on the Wismer and Becker Contracting Engineers (W&B) Operation Process Traveler for the Installation of the Reactor Recirculation Process Fluid Piping System, Rev. 6, (Loop B) Submittal No.10030F:
A diamond notation was added to all (190) operations a.
except one (No. 75) between June 1,1978 and June 8,1978.
NOTE: Diamond notation m*=na step can be performed concurrently or out of sequence with other steps, b.
Numerous foremen signed-off dates on the traveler indicating steps were performed out of sequence even prior to adding the diamond notaticus described in "a" above.
Numerous W&B QC holdpoints were bypassed.
c.
2.
Contrary to 10 CFR 50, Appendix B, Criterion XVI and Enrico Fermi Unit 2 QA Manual, QA Procedure No.17, Rev. 4, Paragraph 1V.1.1, on August 1,1978, the inspector determined that W&3 personnel failed to promptly identify, report and take corrective action relative to the repair of weld No.N21-2336-2WO on drawing No. 6M721-2336-1. Numerous defects were identified on the root pass by radiographic ex2Mnation and had been removed by grinding.
r Eight areas in the root pass had been ground through and as a result the weld end configuration such as, land thickness and bevel angle, no longer met the requirements of W&B welding pro-cedure No.103, Rev. 6.
Further, four of the eight ground through areas had a gap greater than the 1/8-inch allowed.
l 78toz&bt7S-
Appendix A,
The inspector concluded that no corrective action was planned e
since he observed on August 1,1978 that the weld joint was being purged and pre-heated in preparation for welding.
The failure to promptly identify, report and take corrective action is a repetitive item that was identified previously in IE report No. 50-341/78-08.
3.
Contrary to 10 CFR 50, Appendix 3, Criterion IVII, Enrico Fermi Unit 2 QA Manual, QA Procedure No. 18, Rev. 4, paragraph 18.1 and Appendix 3 to W&B Procedure No. WB-E-109, Rev. 3, on August 2 and 3, 1978, the inspector determined that the velder identification was not recorded on the Weld Process Centrol Sheet for the following welds:
Wald No. B17 on drawing No. GE731-E-756.
a.
b.
Weld No. N21-2336-2WO on drawing No. 6M721-2336-1.
Weld No. E11-2327-3W4 on drawing No. 6M721-2327-1.
