L 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 March 5, 1989, through April 5,11989, 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:

Technical Specification (TS) 6.8.1 requires that prccedures recommended in Appendix j A of , Regulatory Guide 1.33, Revision 2, be established implemented and l maintained. This includes maintenance, operating, surveillance, - and fuel handling procedures. The requirements of TS 6.8.1 are implemented in part by the following procedures:

a. _IMI-99, TT-601A, Revision 6, Response Time Testing of Engineered Safety Features Actuation Slave Relays, provides instructions for testing certain Solid State Protection System components.

Contrary to the requirements of T.S. 6.8.1, on March 25, 1989, procedure IMI-99, TT-601A, Revision 6, was inadequate in that prior to allowing the return of the solid state protection system to normal followin'g response time testing, the procedure did not include provisions to reset permissives P-11 and P-12. As a result two separate inadvertent reactor-trip signals were generated for Unit 2 while it was in cold shutdown for refueling.

b. 50I-30.7, Revision 19, Onsite Electrical Power Systems Board Room Heating, i Ventilation and Cooling, and 50I-30.1, Revision 28, Centrol Building and '

Control Room Heating, Venting and Cooling, provides the conditions for operation, precautions and instructions for the tornado dampers associated' with the control room emergency ventilation system.

Contrary to the provisions of T.S. 6.8.1, procedures 501-30.7 and S01-30.1 were inadequate in that precautions and instructions were not included to stipulate that closing the dampers renders the control room emergency ventilation system inoperable and places the plant in Limiting Condition for Operation (LCO) 3.7.7 for one train inoperable and in LCO 3.0.3 when both trains are made inoperable. As a result of this inadequacy, the tornado dampers for both trains were closed at 8:30 a.m. on March 20, 1989, placing the plant in LC0 3.0.3. Plant operators did not realize that the control room emergency ventilation system was inoperable until 2:50 p.m. of the same day. The operators immediately opened the dampers and exited the LCO. j 8905170233 890509 PDR ADOCK 05000327

c. Sequoyah Engineering Procedure, SQEP 39, Revision 6, Review and Approval of Vendor Manuals / Revisions, implements control of vendor input and insures -that vendor manuals ' reflect complete information for the applicable equipment.

Contrary to the requirements of T.S. 6.8.1, SQEP 39 was not followed in that the controlled vendor manual for Copes-Vulcan Valve, 2-FCV-74-2 did not contain the latest revision of the vendor's manual for the valve operator. A 1971 revision of the Limitorque Operator Manual was included as part of the controlled vendor manual and a 1983 revision was utilized for work planning.

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

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 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.

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.
