• • " ,' f N/ f; t Washington, D. C. 20555 C9 Subj ect: Arkansas ight Company Arkansas Nuclear One-Unit 1 Docket No. 50-313 License No. DPR-51 Proposed Technical Specifications

Dear Mr. Ziemann:

Attached find several proposed technical specifications concerning spray chemical additive tanks, emergency cooling pond, and tendon surveillance.

The basis for' change for each is as follows:

Pages 36, 37, 39 - The changes to Specifications 3.3.1 and 3.3.4 establishes level and 'concentiation bands for spray chemical addi-tive tanks based on as' built data. The establishment of error bands on the required parameters provides more flexibility in surveillance requirements and limiting conditions for operation, yet results in no reduction in the margin of safety to the public. No effect on plant operation will result.

Pages 66a,110a - Annual sounding of the emergency cooling pond showed that the pond depth was not the required 3.0 ft. with the surface elevation at 344 ft. O inches. Therefore, per Specification 4.13.2, a change to Specifications 3.11.1 and 4.13.1 is necessitated, llowever, to avoid future changes to the Technical Specifications in the event that the pond bottom elevation again changes, the specifi-cations have been revised to eliminate elevations and show minimum water depths in their stead. The re isien to Specification 3.11.1 also allows time to bring the pond level to a depth of > 3 ft. during power operation which will add flexibility to plant operation.

Page 8C - With the issue of Regulatory Guide 1.85, Rev.1, " Inservice Inspection of Ungrouted Tendons in Prestressed Concrete Containment Structures" (July 1974), it has been determined that the frequency of tendon surveillance does not warrant the requirement to perfom tendon surveillance the second year after the initial containment structural integrity test. Deletion of the second year tendon surveillance will not jeopardize the structural integrity of the containment due to tendon surveillances which will take place 1 and 3 years after the structural integrity test. These surveillances will serve to determine the performance of the system during its initial years. No impact on plant operation will.-result.

Youi prompt review, coments and/or approval is requested.

Very truly yours, 1
