Theabovetabulation indicates thattheavailable NPSHexceedstherequiredNPSHunderthehightemperature CCWconditions.

Including thesurgetanklevelandflowinstrument uncertainty atthemaximumnormalprocedural CCWflowof9194gpmindicates thatapproximately 26ftabsofmarginexist.However,themaximumflowisnotarequirement ofthecooldownanalysis.

Thecooldownanalysisstipulates amaximumCCWflowof8000gpm.Allowingforinstrument uncertainty at8000gpmof2.38%resultsinaflowof8190gpm.Thisisacceptable sincethetabulation indicates thatmarginexistatthehigherflowstabulated.

Itisnotedthatthe9000gpmmaximumflowisstatedinplantprocedure 1,2OHP4021.016.003 (normalCCWoperation).

Duringnormalplantoperating conditions theCCWtemperature isatthedesignbasisnumberof95'F.Atthistemperature, theCCWfluidtemperature suppliedtothepumpis114'FfromtheCCWheatexchanger data.sheet.Thevaporpressureisdetermined tobe1.25psiaor2.91ft.TheNPSHrequirements at114'Fandmaximumflowof9194gpmduringnormaloperation isasfollows:NPSH.i*bi.=H.-H~.+H-Hr=34-291+4609
