T'n'"l7TTTO'h Both the For:ai 2 L., ' cal Spacificationa, paragranh G.O.4.a. ani Ford 2 UPSAR, Secti 5.2.7.8, require that leakage froa ralloactive fluide, be reducai and laaintained to an-loa-an practical leveln. To de.nonntrato the leak tight integrity of the Reactor '7ater Clocinun Syctam, a syntea leakage tcat io coniucted onca por reactor refueling (approximately onco ovary 18 :aontha).
