equivalent to that of the current outage for those examinations listed on the attachment.

L In the current shutdown condition, there is minimal potential for a safety concern posed by deferring these ISI inspections since the affected systems are maintained at low temperature and pressure when compared to their design conditions.

Additionally.. the plant. will-not be brought above cold shutdown without prior NRC 4

concurrence regarding completion of the remaining inspections.
