Attachment to L-2003-036 NRC Request Please comment on successive inspection plans for new Reactor Pressure Vessel (RPV) to Control Element Drive Mechanism (CEDM) tube pressure retaining welds, which are deposited approximately mid-wall of the RPV head. The discussion should include the types of nondestructive examination (NDE) that are going to be performed and the frequency. If successive inspections are not going to be performed, provide the technical justification and basis for not performing a successive/repetitive inspection on the new pressure boundary welds.

FPL Response Regarding successive inspection, FPL will perform successive inspections, on repaired RPV head penetration nozzles that establish a new pressure boundary, The repaired nozzles will receive ultrasonic inspection to include the new pressure boundary weld and at least one inch above the weld in the nozzle base metal. Repaired nozzles will receive a bare metal visual examination of the RPV head surface.
