Docket No.: 50-302 July 6,1979 Mr. W. P. Stewart Manager, Nuclear Operations Florida Power Corporation P. O. Box 14042 Mail Stop C 4 St. Petersburg, Florida 33733

Dear Mr. Stewart:

By Orfer of May 16,1979, the Commissic onfirmed your undertaking a series of actions, both immed' nd long tert, to increase the capa-bility and reliability of t e Crystal Ri -

, Unit No. 3 to respond to various transient events.

In

, the Order confirmed that you would maintain the plant in a shutdown condition until the following actions had been satisfactorily completed:

"(a) Upgrade the timeliness and reliability of delivery from the Emergency Feedwater System by carrying out actions as identified in Enclosure 1 of the licensee's letter of May 1, 1979."

"(b)

Develop and implement operating procedures.for initiating and controlling emergency feedwater independent of Inte-grated Control System control."

"(c)

Implement a hard-wired control-grade reactor trip that would be actuated on loss of main feedwater and/or turbine trip."

"(d)

Complete analyses for potential small breaks and develop and implement operating instructions to define operator action."

"(e) All licensed reactor operators and senior reactor operators will have completed the TMI-2 simulator training at B&W."

By your letter dated May 1,1979 and supplemented by five letters, dated May 16, June 12,15, 22, and 29,1979, you have documented the action' taken in response to the May 16 Order. We have reviewed this submittal, and are satisfied that, with re;pect to Crystal River, Unit 3, you have satisfactorily completed the actions prescribed in items (a) through (e) of paragraph (1) of Section IV of the Order, the specified analyses are acceptable, and the specified implementing procedures are appropriate. The bases for these conclusions are set forth in the enclosed Safety Evaluation.

Mr. W. P. Stewart As noted ~on page 12 of the Safety Evaluation, you are required to conduct a test during power ascension (<l57. rated power) to demonstrate the capability to provide and control emergency feedwater flow to both steam generators independent of the integrated control system.

Appropriate Technical Specifications for Limiting Conditions for Operation and for surveillance requirements should be developed as soon as practicable and provided to the staff within seven days with regard to the design and procedural changes which have been completed in compliance with the provisions of the May 16,1979 Commission Order. The revised Technical Specifications should cover:

(1) Addition of flow rate indication for the emergency feedwater system; (2) Addition of the auto start circuitry for the emergency feedwater pumps; (3) Addition of the anticipatory reactor trips; and (4) Changes in set points for high pressure reactor trip and PORV actuation.

Within 30 days of receipt of this letter, you should provide us with your schedule for completion of the long-term modifications described ir Section II of the May 16 Order.

My finding of satisfactory compiiance with the requirements of items (a) through (e) of paragraph (1) of Section IV of the Order will permit resumption of operation in accordance with the terms of the Commission's Order; it in no way affects your duty to continue in effect all of the above provisions of the Order pending your submission and approval by the Commission of the Tech-nical Specification changes necessary for each of the required modifications.
