NUCLEAR REGULATORY COMMISSION y f).:

WASMNGToN. D. C. 20655 May 15,1981 Docket No. 50-313 Mr. William Cavanaugh, III Vice President, Generation Arkansas Power & Light Company P. O. Box 551 Little Rock, Arkansas 72203

Dear Mr. Cavanaugh:

The Commission has issued the enclosed Acendment No.55 to Facility Operating License No. CPR-51 for Arkansas Nuclear One, Unit No.1.

This amendment consists of changes to the Technical Specifications (TSs) in response to your a:: plication dated April 2,1979, as supplemented October 31, 1980.

This amendment modifies the ANO-1 TSs to require the ANO-1 purge valves ce closed whenever the reactor ccolant system temperature is equal to or greater than 200*F. This amendment also updates pages i and 11 of the TS Table of Contents.

Copies of the Safety Evaluation and the Notice of Issuance are also enclosed.

In our letter of November 29, 1978, we identified the generic concerns of purging and venting of containments to all operating reactor licensees and requested your response to these concerns. Our review of your response was interrupted by the TMI accident and its demands on staff resources.

Consequently, as you know, an Interim Position on containment purging and l

venting was transmitted to you on October 26, 1979. You were requested to implement short-tern corrective actions to remain in effect pending completioq of our longer-term review of your response to our November 29, l

1973 letter.

Over the past several months our contractors and we have been reviewing the responses to our November 1978 letter to close out our long-term review of this rather complex issue. The components of this review are l

as follows:

1.

Confomance te Standard Review Plan Section 6.2.4 Revision 1 and l

Branch Tecnnical Position CSB 6-4 Revision 1.

These documents were provided as enclosures ta our November 1978 letter.

i Mr. William Cavanaugh 2.

Valve Operability Although the Interim Position allowed blocking of the valves at partial-open positions, this is indeed an interim position. Ear-lier we requested a program demonstrating operability of the valves in accordance with our " Guidelines for Demonstrative Operability of Purge and Vent Valves." These Guidelines were sent to you in our letter of September 27, 1979. There is an acceptable alternative which you may wish to consider in lieu of completing the valve qualification program for the large butterfly-type valves. This would be the installation of a fully-qualified mini-purge system with valves 8-inches or smaller to bypass the larger valves. Such a system change might prove more timely and more cost-effective. The system would meet BTP CSB 6-4 item B.1.c.

3.

Safety Actuation Stanal Override This involves the review of safety actuation signal circuits to ensure that overriding of one safety actuation signal does not also cause the bypass of any other safety actuation signal.

4 Containment Leakage Due to Seal Deterioration Position B.4 of the BTP CSB 6-4 requires that provisions be made to test the availability of the isolation function and the leakage rate of the isolation valves in the vent and purge lines, individually, during reactor operations. But CSB 6-4 does not explain when or how these tests are to be performed. After we complete the deveicoment of Standard Technical Specifications which will satisfy our position on this issue, we will forward them to you with a request for consideration of a submittal of proposed TS for A.iO-1.

The status of our long-term review of the above items for the ANO-1 facility is as follows:

1.

Conformance to Standard Review Plans Section 6.2.4 Revision 1 and Branen Technical Position CSB 6 4 Revision 1.

With the issuance of this amendment to your license, this issue is ccmplete for ANO-1. However, if you should decide to request a change in your TS which would allow some purging. Enclosure 4 is a rettatement of salient features of the position as interpreted by the staff. Evaluation of ANO-1 to this restatement and a comparison to BTP CSB 6-4 positions would be needed to reonen thi. review.

2.

Valve Ooerability With tne issuance of this amendment this issue is complete for ANO-1.

~

It is our understanding that you do not intend to qualify the existing valves.

Mr. William Cavanaugh,

3.

Safety Actuation Signal Override This item is complete for ANO-1. Our letter dated August 14, 1980, provided our evaluation and acceptance of the electrical instru-mentation and control design aspects of the override of the containment purge valve isolation and other safety features actuation-signals.

Sincerely, (dohn F. Stolz, Chie-0py' rating Reactors Branch f4 Ofvision of Licensing
