Gentlemen:

SUBJECT: NRC INSPECTION REPORT NOS. 50-327/86-49 AND 50-328/86-49

This refers to the Nuclear Regulatory Commission (NRC) inspection conducted by

K. M. Jenison on September 6 - October 5, 1986. The inspection included a review

of activities authorized for your Sequoyah facility. At the conclusion of the

inspection, the findings were discussed with those members of your staff

identified in the enclosed inspection report.

Areas examined during the inspection are identified in the report. These areas

include a review of licensee action on previous inspection' findings, required

surveillance testing, inadvertent starts of the Emergency Diesel Generators, IE

Information Notices, and License Conditions. Within these areas, the inspection

consisted of selective examinations of procedures and representative records,

interviews with personnel, and observation of activities in progress.

Sequoyah has had a repeated history of failed UHI isolation valve response time

surveillances. The cause of the repeated surveillance failures was not adequately

determined by Sequoyah and corrective action was not taken to preclude further

failures. This violation, described in the enclosed Inspection Report, is under

consideration for escalated enforcement action. Accordingly, no Notice of

Violation is being issued at this time, and no response to this letter is required.

However, please be advised that the number and characterization of violations

described in the enclosed Inspection Report may change as a result of further NRC

review. You will be advised by separate correspondence of the results of our

deliberations on this matter.

In accordance with Section 2.790 of the NRC's " Rules of Practice," Part 2,

Title 10, Code of Federal Regulations, a copy of this letter and its enclosure

will be placed in the NRC Public Document Room.
