1. Item 1 The facility Technical Specifications states in part that " Written procedures shall be established, implemented, and maintained covering the activities referenced below: . . . c. Surveillance and test acti-vities of safety-related cauipment".

Contrary to the above, written procedures have not been established to control the degrading of safety-related Class IE components by the installation of non-Class Il test equipment as resulted in the failure of Channel B Core Protection Calculator on January 25, 1979 (Licensee Report 50-368/79-11).

Previous Response to Item 1 Arkansas Power and Light Co. (APSL) will establish controls for connect-ing test equipment to safety related equipment. These controls will be in place and will have been reviewed by maintenance and operations department personnel by June 1, 1979.

The discussion of this violation in paragraph 7.a of the Details of Inspection Report 79-06 states in part "The licensee has been advised by the inspector that the connecting of non-Class 1E test equipment to a 1E seismic component degrades the design intent of that component and the component' should be considered inoperable per the Technical Speci-ficatior, (TS)".

APSL is still evaluating this interpretation and will respond with the results of their evaluation by May 26, 1979.

Supplemental Response to Item 1 Further discussions have been conducted with Mr. T.F. Westerman, NRC Region IV, concerning the following statement in paragraph 7.a of the Details of Inspection Report 79-06:

"The licensee has been advised by the inspector that the con-necting of non-Class 1E test equipment to a 1E scismic component degrades the design intent of that component and the component should be considcced inoperable per the Technical Specifications (TS)"

The intent of this statement is that if the attachment of test equip-ment to a component could cause that component to fail, then that component must be considered inoperable. However, if the attachment of test equipment could not cause the component to fail, then that component is still considered operable.

The above guidance will be promulgated in plant procedures by July 20, 1979.
