- February 28, 1986 Docket No. 99900100/85-01 Limitorque Corporation ATTN: Mr. F. K. Denham Executive Vice President 5114 Woodall Road Lynchburg, Virginia 24502 Gentlemen:
This refers to the inspection conducted by Mr. James T. Conway of this office on November 4-8, 1985, of your facility at Lynchburg, Virginia, and to the discussions of our findings with you and members of your staff at the conclusion of the inspection.
This inspection was made as a result of the receipt of 10 CFR Part 50.55(e),
Licensee Event (10 CFR 50.73), and 10 CFR Part 21 reports from: (1) Gulf States Utilities Company relating to the loss of torque of Reliance motors containing magnesium rotors, (2) Washington Public Power Supply System pertaining to valve / actuator weight discrepancies, (3) Public Service Electric and Gas Company on replacement actuators having different spring packs, and (4) Connonwealth Edison and Tennessee Valley Authority on qualification of internal wiring. Within these areas the inspection consisted of an examination of procedures and representative records, interviews with personnel, and observations by the inspector.
With regard to the environmental qualification of internal wiring of your motor valve operators, the inspection determined that even though your operator qualification test reports do not specifically address internal wiring or wiring qualification, you are able to support (by separate documentation) qualification of internal wiring (specifically Raychem Flametrol and/or Rockbestos Firewall SIS) you have installed in nuclear supplied valve operators. The inspection also determined that while you can support qualification of the above wires you have insta11ad, valve manufacturers, licensees, or others may have added wires which are not qualified by your data. Since the inspection at Limitorque, the NR0'has further determined, from inspections at several licensees that there is some Limitorque installed wiring (e.g., TEW and TW) in valve operators used in nuclear plants in harsh environment, safety-related systems that is not qualified by the Raychem or Rockbestos data. Even though these operators and their wiring may have been manufactured several years ago to non-nuclear requirements, licensees have a requirement to qualify the operators and wiring to appropriate qualification requirements. Since this Limitorque installed .
wiring is not qualified by the Raychem or Rockbestos data and the valve !
manufacturer, licensee, or other contractor installed wiring may not be '
qualified by the Raychem or Rockbestos data, the NRC is concerned with how this wiring is environmentally qualified for use in Limitorque operators used in nuclear plants.
