Leakage integrity tests with a maximum allowable leakage rate for purge supply and exhaust isolation valves will provide early indication of resilient material seal degradation and will allow the opportunity for repair before gross leakage failure develops.The 0.60 L leakage limit shall not be exceeded when the leakage rates determined 3y the leakage integrity tests of these valves are added to the previously determined total for all valves and penetrations subject to Type B and C tests.ST.LUCIE-UNIT 2 B 3/4 6-2 Atttendment No.
