ENCLOSURE I NOTICE OF VIOLATION Tennessee Valley Authority Docket Nos. 50-327 and 50-328 Sequoyah License Nos. DPR-77 and DPR-79 The following violation was identified during an inspection conducted on February 24-28, 1986. The Severity Level was assigned in accordance with the NRC Enforcement Policy (10 CFR Part 2, Appendix C).

Appendix B, Criterion V of 10 CFR 50, requires that activities affecting quality shall be prescribed by documented instructions and procedures, and shall l>e accomplished in accordance with these -instructions and procedures.

TVA Sequoyah Nuclear Plant 79-02 Anchor Bolt inspection procedure requires the correct installation of self-drilling concrete anchor bolts in safety-related systems per General Construction Specification G-32. Para-graph 3.2.5 of Specification G-32 states that the installers are to be instructed to tighten the bolts between 1/8 and 1/4 turn after the bolt head comes into contact with the attachment or baseplate.
