DearMr.Vissing:
TheServiceBuildingfiresuppression sprinkler systemwasremovedfromservice,thusrequiring anhourlyfirewatchtour.Therequiredhourlyfirewatchtourwasprematurely suspended, priortothesystembeingdeclaredoperable.
Inaccordance withtheGinnaStationTechnical Requirements Manual(TRM),SectionTR3.7.2,RequiredActionC.1,whichrequiresaSpecialReportoutlining thecauseofthesysteminoperability andplansforrestoring thesystemtooperablestatus,thisthirty(30)daySpecialReportisbeingsubmitted.
OnApril7,1997,atapproximately 1600EDST,thesuppression systemwhichprotectstheServiceBuildingwasremovedfromserviceanddeclaredinoperable.
Thesystemwasdeclaredinoperable tocompletetheremovalofseveralsystemsprinkler headswhichwerenotrequired.
Compensatory actions,consisting ofanhourlyfirewatchtour,weretakenuponthestartofthemaintenance activities asrequiredperTR3.7.2RequiredActionB.Maintenance activities werecompleted at1730EDSTonApril7,1997,andthesystemwasventedandfilled(afterthemainisolation valveforthissuppression systemwasreturnedtothefullopenposition).
Firewatchactivities wereprematurely suspended at1730EDST,sincethefirewatchpersonnel assumedallactivities werecompleted.
However,Operations didnotadministratively declarethesystemoperableuntil2100EDSTonApril7.Atapproximately 0700EDSTonApril8,itwasdiscovered thattherehadbeenalapseinhourlyfirewatchcoveragefrom1730EDSTto2100EDSTonApril7.ACTIONReport97-0564wasinitiated andfirewatchpersonnel wereadvisedthatOperations approvalisrequiredto~discontinue compensatory measures.
