Se temperature and pressure inside containment peak at 283*F and 52.0 psia in 17 .ind 50 seconds, respectively. At I hour the conditions are 214.7'F and 32.32 palas at 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> the conditions are 204*F and 29.46 psia; at 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> the conditions are 193.2*F and 27.08 j psia; and at 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> the conditions are 143*F and 18.03 psia. Se containment returns to ambient conditions in 7 days.
l Based on this information, it can be concluded that the laboratory test subjected the valve motor operator to an overall '
i more severe environment than that which would result from a postulated IACA. Since the valve motor operator remained
! operable throughout the test and functional af ter the test, it can be concluded that the valve motor operator will remain j functional during and af ter exposure to the accident environment which would result from the postulated IACA. (Reference G, j H, and X).
- 2. CAL-40 qualifies components tested in a high pH boric acid spr.ny to a pH value of S.
i
- 3. This valve motor operator will become flooded during a LOCA. %e valve will be submerged in 10 minutes 54 seconds after a j IDCA. 21s is a worst-case value based on a postulated DBA IDCA. For smaller IDCAs, component submergence will occur j further into the accident, if it occurs at all. This valve motor operator is the core floodi.sg tank 42 injection isolation i valve motor operator. Once this valve is fully opened and before the reactor coolant pressure reaches 725 psig, the breaker
. of tha combination line starter of the valve motor operator will be tripped open and padlocked. This valve motor operator
} is not required to operate to mitigate the IDCA. Since this.v.tive operat.or is not required to operate to mitigate the l accident, failure of this valve would not impact other safety-related functions or mislead an operator. (Reference CAL-49 l and Elem. Wiring Diag. 7749-E528-SH27) i 4
