- All vital cables inside containment have been qualified to at least 271°F and 2 x 108 rads at 43~2 psig for LOCA environment.
- Thermal analysis have been performed using the same model as VEPCO, which has previously been accepted by the staff.
Results of this analysis show that the peak surface temperature of the worst case cable type is 333°F.
Identical cables, irradiated with a total dosage in excess of that encountered in a MSLB have successfully passed tests at 34QOp for= 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />.
