ITEM:

Valve operators (Limitorque) for component cooling water system valves.

\\

SUPPLIED BY,

Westinghouse Water Reactor Divisions.

NATURE OF DEFICIENCY CPSL identified in July, 1984 that motor operators supplied by Westinghouse for certain butterfly valves in the component cooling water system were not qualified as 1E.

Failure of the operators could create the inability to separate the redandant trains of component cooling water, except by manual closure via the hand operators.

REASON PROBLEM IS REPORTABLE: Failure of the operators could lead to a degraded safety condition.

I IBMD-WKBB01-OS4

x CORRECTIVE ACTION:

Westinghouse has evaluated the Limitorque operators supplied for these valves and has determined that they are qualified for IE applications without modification. Westinghouse submitted the
