g a FINAL REPORT OF SIGNIFICANT CONSTRUCTION DEFICIENCY NO. 110 "G.H. BETTIS (PART 21) VALVE ACTUATORS" INTRODUCTION This report is submitted pursuant to 10CFR50.55(e). It describes the problem concerning the potential degradation of performance related to actuator stroking times described in G.H. Bettis (Part 21).

This deficiency was notified to USNRC by G.H. Bettis Company in their 10CFR21 Report No. CAR #0023, dated February 13, 1984.

DESCRIPTION OF PROBLEM In their 10CFR21 report, dated February 13, 1984, Bettis identified the series /model numbers of their actuators which have potential of degradation in stroking times due to a particular combination of seal and grease used in the original manufacture.

Our review of series /model numbers of all Bettis manufactured actuators employed at Waterford Unit No. 3 valves and dampers revealed that there are only five (5) valve operators that fall under this classification. These five valve tag number are: 3CC-B187A/B, 3CC-B188A1, 3CC-B189B1, 3CC-B190A2, and 3CC-B191B2.

SAFETY EVALUATION The five valves identified above are located inside containment in lines supplying cooling water to RC pump motors and CEDM cooling coil. These components are not required to operate following a design basis accident and this cooling water is supplied from the nonessential seismically-qualifirsd component cooling water loop, which is isolated from the essential loop on a containment isolation signal. The failure of these valves to operate will not affect the ability of the Component Cooling Water System to perform its intended function following a design basis accident.

Hence, we have concluded that the above problem is not reportable under 10CFR50.55 (c) .

CORRECTIVE ACTION The five valve actuators in question will be serviced with new seals and Dow Corning Holykote 44 lubricant in accordance with the recommendations contained in the C.H. Bettis 10CFR21 report.
