APPENDIX A NOTICE OF VIOLATION Gulf States Utilities Docket: 50-458 River Bend Station Permit: CPPR-145 Baseo on the results of an NRC inspection conducted during the period of

, . April 15-19 and April 29 - May 3, 1985, and in accordance with the NRC Enforcement Policy (10 CFR Part 2, Appendix C), 49 FR 8583, dated March 8, 1984, the following violation was identified:

A; High Strength Steel Bolts Preload Criterion V of Appendix B to 10 CFR Part 50 states, in part, " Activities affecting quality shall be . . . accomplished in accordance with . . .

instructions, procedures, or drawings. . . ." This requirement is implemented by paragraph 3.2 in QAP-5 of the Quality Assurance Program Manual which asserts the same.

The specification, " Structural Joints Using ASTM A325 or A490 Bolts,"

dated May 8,1974, requires fasteners to have a preload.

' Contrary to the obove, an inspection of the " Job Inspection Torque" (JIT) which was used to verify preload found that, of 200 bolts in 72 different connections, inspected on 14 inspection reports (irs), there were 8 with ,

significant failures. A significant failure was defined as a nut slipping at less than 90% of JIT. The 8 failures averaged about 67% and ranged from 27% te about 88% of JIT.

This is a Severicy Level IV Violation. (SupplementII.D) (458/8540-01)

B. . Inspection Records Criterion XVII of Appendix B to 10 CFR Part 50 states, in part,

" Sufficient recorde chall be maintained to furnish evidence of activities affecting quality. . . ."

Contrary to the above, suf'ficient records were not maintained to furnish evidence of activities affecting quality in certain cases. In the seven irs, which were generated by six different inspectors, it was found that 29 of the 61 connections checked did not have satisfactory documentation.

Examples of structural inspection activities with this problem are:

1. The number of bolts found in a connection and also detailed on drawings did not agree with the number of bolts reported on the irs

'in 18 of the 61 connections checked.
