WPPSS fiUCLEAR PROJECTS l10. 3 AfiD a fu RESP 0l1SE TO IE BULLETIll 80-09 P,eEEence: 1) Letter, G03-80-1521, D. L. Renberger (WPPSS) to H. D. Thornburg (flRC), same subject, dated 6/25/80.

2) Letter, G03-80-2291, D. L. Renberger (WPPSS) to H. D. Thornburg (flRC), same subject, dated 9/22/80 The above reference letters forwarded the Supply System's initial response and status update on IE Bulletin 80-09, "Hydramotor Actuator Deficiencies."

As stated p cviously in the referenceil letters, we have two Contractors that are supplying actuators that wera the concern of the subject bulletin. They are Valtek Inc. and Anerican Warming and Ventilation Company. The Valtek supplied actuators do not use the springs manufactured from incorrect material and the actuators have been sized adequately using the new nomo-graphs supplied by the actuator man 9facturer. American Warming and Ventilation supplied actuators are being subjected to examination, testing and corrective action as described in referenced letter flo. 2, for assurance of output adequacy. This program will be implemented to the completion of the work under their contract with the Supply System.
