It describes the problem concerning the potential degradation of perforr.ance related to elspred tien fic, =anufacture by Bettis actuators. This deficiency vss retified to USSRC by G.M. ?ettis Cer;;ay In r: ' r h' < 21 Report No. CAR #0023, dated February 13, 1934 DESCRIPTION OF PROBLEM In their 10CFR21 report, dated February 13, 1984, Bettis idertiff.d the series /codel numbers of their actuators which have potential of d.' grade tica in stroking times due to a particular combination of seal and grease used in the original canufacture. Our review of series / odel nunbers of all Bettis canufactured actestcrs e= ployed at k'aterford Unit NO. 3 valves and danpers revealc d that there a.-e cnly five (5) valve operators that fall under this classification. There five valve tag nu=bers are: 3CC-3187A/B, 3CC-5188A1, 3CC-5189B1, 3CC-5190A2, and 3CC-B191B2. SAFETY E5*!.LL'ATION The five valves identified abcVe are located inside contain:ent in linus supplying cooling water to RC pu=p notors and CEDM cooling coil. 30t h of ti.. se ec=ponents are not required to operate following a design i rris acef dent e nd this cooling veter is supplied from the nonessential seist'cally-c,ua}ified cc=penent cooling water loep, which is isolated frem the ecstntial loop en a ccntain=ent isolation signal. The failure of these valves to cperate vill not affect the ability of the Cc=ponent Cooling k*ater System to perform its intended function folleving a design basis accident. Hence, we have concluded that the above problem is not reportable under 10CFR50.55(e). CORRECTIVE ACTION The five valve actuators in questien vill be cerviced with new scals and Dev Corning Molykote 44 lubricant in accordance with the reco: endatiens contained in the G.H. Bettis 10CFR21 report. O e f-oh9 -/V4d 4 f/Y/
