TiNVID ENCLOSURE 1 NOTICE OF VIOLATION Tennessee Valley Authority Docket Nos. 50-327, 50-328 Sequoyah License Nos. DPR-77, DPR-79 During the Nuclear Regulatory Commission (NRC) inspection conducted May 1-30, 1988, a violation of NRC requirements was identified. In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1988), the violation is listed below:

10 CFR 50, Appendix B, Criterion XVI states that measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected.

Criterion XVI further states that in the case of significant conditions adYerse to quality, the measures shall assure that the cause of the condition is determined and corrective action taken to preclude repeti-tion. This requirement is implemented at Sequoyah by the Nuclear Quality Assurance Manual (NQAM), the accepted QA program (TUA-TR75-1A) and Administrative Instruction (AI) 12, Adverse Conditions and Corrective Actions.

Contrary to the above, the licensee faileo to initiate any long-term corrective actions to prevent the recurrence of events where positive reactivity changes were made while both trains of the Control Room Ventilation System were inoperable. These positive reactivity changes were violations of Action Statement (b) to Technical Specification 3.7.7 which occurred during September through December 1987 and were reported to the NRC through Licensee Event Report 327/87078.

As of April 1, 1988, the licensee had not revised (or provided for future revision of) site procedures Technical Instruction (TI)-19 (Chemical Feed Controls), 501-62.2 (Boron Concentration Control), and SOI 62.3 (Reactor Coolant Chemical Addition and Contiol) by which positive reactivity changes occur during chemical additions. No other administrative controls related to these events had been issued.

Pursuant to the provisions of 10 CFR 2.201, Tennessee Valley Authority is hereby required to submit a written statement or explanation to the Nuclear Regulatory Comission, ATTN: Docum.ent Control Desk, Washington, DC 20555, with a copy to the Director, Office of .Special Projects, and a copy to the NRC Resident Inspector, Sequoyah, within 30 days of the date of the letter i transmitting this Notice.
