Theprocessinvolvesmatchingthepumpdischarge pressureswingrelativetothedesiredpressureandobservethepumpstrokerateascomparedtothedatainthetestreport.Inaddition, thetestreportexplicitly statesthattheleakratecorrection dataapplyonlytotheas-tested configuration.

ForthetestingatSt.LucieUnitI,itwasrequested thatthecapability beprovidedtotestinthestraighttubeportionsatelevations wellabovethetubesheet.
