Enclesure REQUEST FOR INFORMATION ON TU ELECTRIC RESPONSE TO IEB 79-28 Inspection Reports 50-445/85-16 and 50-446/85-13 identified a discrepancy between the part numbers on travelers EE 62-1415-5801 and EE 83-0373-5801 and the part numbers on the installed NAMCO switches. The discrepancies in part numbers indicate that switches with specific environmental qualif-ication specifications and physical orientation requirements (counter clockwise rotation) have been installed on the RHR systen valves contrary to the installation instruction and design requirements. On what basis has TV Electric determined that the NAl'C0 switches installed on 1-HCV-606 and 1-FCV-618 are acceptable? On what basis does TV Electric know that other NAMCO switches installed in the plant satisfy relevant design basis requirements?
