Part 21 - Defective MOV T-drains
Environmentally qualified MOV's to be operable, must have T-drains
installed to relieve moisture, buildup in a harsh environment following a
While inspecting the spare motor, prior to installation, on MOV 856D, an
EQ MOV, it was found to have defective T-drains. This was observed as an
apparent manufacturer's defect. The T-drain, supplied by Limitorque
Inc., Lynchburg, Virginia, was not drilled through and would act as a
pipe plug rather than as a drain. This motor had been removed from the
spare actuator for MOV 536. The actuator had been removed from service
in 1993, rebuilt, and stored for future use. The defective T-drains have
been removed and properly drilled ones were installed. All the other EQ
MOV's were inspected and several were found to have similar defective T-
drains; these were also removed and properly drilled T-drains have been
installed on all EQ MOV's.
A written report of this condition will be prepared and submitted to the
NRC per 10CFR21.21.
