C. Technical Specification 6.8.1.e states that written procedures shall be established, implemented and maintained covering site Radiological Emergency Plan (REP) implementation.

The Sequoyah Radiological Emergency Plan IP-1, Emergency Plan Classifi-cation logic which implements these requirements, requires that the operators enter a Notification of Unusual Event if the primary system leak rate is greater than that allowed in the Technical Specifications.

Sequoyah Radiological Procedure, IP-2, Notification of Unusual Event, requires that the notification of the Operations Outy Specialist be made within 5 minutes after the declaration of the event.

In addition, REP Implementing Procedure IP-1, also states, if there is any reason to doubt whether a given condition has actually occurred, the shif t engineer or Site Emergency Director will proceed with the required notification without waiting for formal confirmation.

Contrary to the above, on April 6, 1988 at 7:55 a.m. the licensee entered LC0 3.4.5.2 acknowledging that the RCS leakrate was greater than the TS allowable limits and did not enter a NOVE until 8:20 a.m. when licensee and NRC management reviewed the event. This is a violation of the above requirements.

This is a Severity Level IV violation (Supplement VI!!).

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 Director, Office of Special Projects, 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, r.onsideration will be given to extending the response time. If an adequate r0 ply 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.
