10 3.7 (Contd)

-leakage rate shall yield an overall leakage rate not greater than 0.5%/ day at 27 psig.

(d) A containment sphere integrated leakage rate test shall be /

performed at a pressure not less than 11.5 psig in conformance with /

the criteria specified in Appendix J of 10 CFR 50. .Three tests /

shall be conducted at 40 10 month intervals during each 10-year /

service period. /

(e) If any containment sphere integrated leakage rate test (ILRT) fails /

to meet the specifications of 0.5%/ day of contained atmosphere /

(weight basis) at the design pressure (27 psig) or extrapolated to /

the design pressure, the test schedule for subsequent ILRTs shall /

be reviewed and approved by the Commission. If-two consecutive /

ILRTs fail to meet these specifications, then an ILRT shall be /

performed at least every 18 months until two consecutive ILRTs meet /

the acceptance criteria, at which time the above test schedule may /

be resumed. /

(f) The accuracy of each ILRT shall be verified by a supplemental test /

in accordance with Appendix J of 10 CFR 50 which confirms the /

accuracy of the test by (1) verifying the difference between the / (

supplemental test data and the ILRT is 0.25 aL or 0.25 L , (2) /

continuing the test for a duration sufficient to establish /

accurately the change in leakage rate between the ILRT and /

supplemental test. /
