[ NOTICE OF VIOLATION Detroit Edison Company Docxet No. 50-341 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. A diamond notation was added to all (190) operations 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.

c. Numerous W&B QC holdpoints were bypassed.

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 r

pass by radiographic ex2Mnation and had been removed by grinding.

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.

Appendix A ,

e - The inspector concluded that no corrective action was planned

.' 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:

a. Wald No. B17 on drawing No. GE731-E-756.

b. Weld No. N21-2336-2WO on drawing No. 6M721-2336-1.

c. Weld No. E11-2327-3W4 on drawing No. 6M721-2327-1.
