Duringthetest,thesystemwassetuptoprovidetheproperflowsplitbetweeninjection points,andbothpumpshadanacceptable leveloftotalflowtosatisfytheminimumflowrequirements.

Furtheradjustment ofthethrottlevalvesinthepipingconfiguration toallowtheEastpumptomeetthemaximumflowrequirement willinfringeupontheminimumflowrequirement fortheWestpump~Inordertoalleviate thissituation, itwouldtherefore requirephysicalreworkandretesting oftheEastpumptoloweritsperformance totheextentthatmaximumflowcamewithinT/S.Suchreworkandretesting isestimated todelaytheUnit1startupbytwoweeksorlonger.Therefore, onthebasisoftheneedforpowerandtheplantbeingsubjected toanunnecessarily longshutdown, werequestatechnical specification changetoallowustooperateinour"astestedcondition".
