Since the maintenance work was being performed on plant equipment that could have an ef fect on nucicar safety, the need for corrective maintenance procedures should have been considered in accordance with the requirements of plant Administrative Control Directives 4 ACD-5.2, Mechanical and Electrical Maintenar. s Procedures, and 4 ACD-3.11, Procedure Review and Approval. These ACDs have been prepared to establish guidelines and requirements to govern plant activities, particularly activities relating to nucicar safety and/or those required by the Technical Specifications.

In direct response to the infraction identified in Inspection Report No. 050-263/75-01, an Operational Control Document has been drafted to control the performance of maintenance on RHR heat exchangers and a procedure has been draf ted for the perfc-mance of the maintenance work.
