Pressurizationofthecontainmentstructurestartedat2120hoursonMarch20,1987,atanaveragepressurizationrateof3.4psi/hr.Soonafterthestart'fpressurization,twotemperaturesensorswerebeginningtoexhibitanomolousbehavior.TE-40(Elevation194')displayederraticreadingsonthedataloggerrangingfromanopenconnection(highresistance)to-453F.ThediagnosedfaultwithTE-40waslooseconnections0atsomepointinthecontainment.TemperaturesensorTE-40wasdeletedfromallcomputercalculations,andtheremainingtemperaturesensorsatthatelevationreceivedadjustedvolumefractions.TheISGcalculationspresentedinSectionII.B.5wereperformedtoaccommodatethedeletionofTE-40.TheISGvalueremainedat0.041percentperday,wellbelowthelimitof0.125percentperdayforan8.25hourILRT.TemperaturesensorTE-36(Elevation171'wasnotedtobereading0approximately7Fbelowtheothertemperaturesensorsatthatelevation,butexhibitedstablebehaviorandwasfollowingthetrendoftheothertemperaturesensorsatthatelevation.ThedecisionwasmadenottoofficiallydeletetemperaturesensorTE-36atthistime,buttomonitoritsbehaviorduringthebalanceoftesting.Duringfinalstagesofpressurization,leakagesurveyteamsfoundevidenceofsmallleaksattheleakagechasesforthefollowingpenetrations:P-9InstrunentAirP-14NitrogenSu)plyP-26CVCSLetdownAllleakagefromthesepathswasestimatedtobelessthan5percentoftheILRTacceptancecriteria,andnorepairsoradjustmentsweremadetothesepenetrations.
