,i 4 ENCLOSURE 1 NOTICE OF VIOLATION Tennessee Valley Authority Docket Nos. 50-327, 50-328 Sequoyah Units 1 and 2 License Nos. DPR-77, DPR-79 During the Nuclear Regulatory Commission (NRC) inspection conducted from June 6 through July 5, 1989, three violations of NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1989), the violations are listed below:

A. Technical Specification 3.6.5.2 states that the ice bed temperature monitoring system shall be OPERABLE with at least two operable RTD channels in the ice bed. TS 3.6.5.2, LCO Action statement a, states that with the ice bed temperature indication not available in the main control room, determine the ice bed temperature at the local ice condenser temperature monitoring panel every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Centrary to the above, from May 4, 1989 through June 29, 1989, Unit 2 operated at 100% power without an OPERABLE ice bed temperature monitor /

recorder in the main control room and the ice bed temperature at the local ice condenser temperature monitoring panel was not determined.

This is a Severity Level IV violation (Supplement I).

B. 10 CFR 50.59 states that the holder of a license authorizing operation of a production or utilization facility may make changes in the facility as described in the safety analysis report without prior Commission approval unless the proposed change involves an unreviewed safety question or a change in the technical specifications incorporated in the license.

SQA-119, Evaluation of Changes, Tests, or Experiments, implements the requirements of 10 CFR 50.59. Sequoyah administrative instruction Al-9, Control of Temporary Alterations, is the site approved process that implements performance of safety reviews for temporary changes. AI-9 provides requirements for installing, controlling, returning to normal, and documenting temporary alterations for safety related systems. AI-9 states that for temporary alterations that are installed on equipment that is out of service and normally excluded from the requirements of AI-9, if the instruction is complete or cannot be completed and the temporary alteration must remain installed, the temporary change shall be documented and controlled by AI-9.

Contrary to the above, Surveillance Instruction SI-477, Backup Ice Condensor Monitoring, was utilized by the licensee to perform a temporary 8908210020 890810 PDR ADOCK 05000327 Q PDC -_ ____ _ _ - - -_- _ - _- - _ __ _ _ _ _ _ _ _ _ _ __

alteration' to -the ice bed temperature monitoring system which remained l installed without being controlled 'and documented as = a temporary alteration.in accordance with AI-9. This resulted in a failure to perform

.a . determination of whether or not. an unreviewed safety question existed j pursuant to 10 CFR 50.59 as' required by-SQA-119.

'This 1s a Severity Level IV violation (Supplement I).

L C. -10 CFR 50 Appendix B,- Criterion XVI states . that measures shall be established to assure that conditions adverse to' quality such as failures, malfunctions and defective equipment, and nonconformances are promptly

-identified and corrected.

t_ Contrary to the above, during the period of June 25 to June 30, 1989, Sequoyah Plant management failed to take corrective action to resolve problems 'with control room ice bed temperature monitor operability and to ensure that a proper review was conducted pursuant to 10 CFR 50.59 for installation of a digital temperature indicator.

This is a Severity Level IV violation (Supplement I).

Pursuant to the provisions of 10 CFR 2.201, Tennessee Valley Authority is hereby required Lto submit a written statement.or explanation to - the Nuclear Regulatory. Commission, ATTN: Document Control Desk, Washington, DC . 20555, with a copy. to the Associate. Director for Special Projects, Office of Nuclear Reactor Regulation, and a copy to the NRC Resident Inspector, Sequoyah, within 30' days of_the date of the letter transmitting this Notice. This reply should be clearly marked ts a " Reply to a Notice of Violation" and should include [for each violation]: (1) admission- or denial of the violation, (2) the reason for

- the violation if admitted, (3) the corrective steps which have been taken and the results achieved, (4) the corrective . steps which will be taken to avoid-further violations, .and' (5) the date when full compliance will be achieved.

Where good cause is shown, consideration will be given to extending the response time. If an adequate reply is not received within the time specified in this Notice, an order may be issued to show cause why the license should not be modified, suspended, or revoked or why such other action as may be proper should not be taken.
