. 1 ENCLOSURE 2 NOTICE OF DEVIATION Tennessee Valley Authority Docket Nos. 50-327 and 50-328 Sequoyah Units 1 and 2 License Nos. DPR-77 and DPR-79 The following deviation was identified during an inspection conducted on April 6 - May 5, 1986.

Facility Operating License (FOL) No. DPR-77, Section 2.C.(23)E. and FOL No. DPR-79, Section 2.C.(16)f. require the installation of reactor coolant system and reactor vessel head high point vents that are remotely operable from the control room. The licensee utilizes the pressurizer power operated relief valves (PORVs) as the reactor coolant system high point vents.

In a letter dated July 16, 1982, the licensee committed to provide guide-lines for reactor operator use on the release of noncondensibles from the reactor coolant system in accordance with an Emergency Operating Instruction provided as an attachment to the letter. -The attachment described the use of the PORVs for this function in the event of the failure of the Reactor Vessel Head Vent System (RVHVS).

In a letter dated February 15, 1984, the licensee committed to implement these procedures at the time that the upgraded emergency operating instructions were implemented. By order dated June 15, 1984, the Nuclear Regulatory Commission required implementation of the upgraded emergency operating procedures by August 1985 for both units.

Contrary to the above, the licensee failed to meet the commitment in the July 16, 1982, and February 15, 1984 letters in that the upgraded Sequoyah Emergency Instructions do not include procedures for use of the pressurizer PORVs as reactor coolant system high point vents.

Please provide, in writing within 30 days of the date of this Notice, a descrip-tion of corrective actions regarding this deviation, actions taken to avoid further deviations, and the dates when these actions were or will be completed.

Security or safeguards information should be submitted as an enclosure to facilitate withholding it from public disclosure as required by 10 CFR 2.790(d) or 10 CFR 73.21.
