ABSTRACT
During a recent refueling outage (April 2005), Dominion Nuclear Connecticut (DNC) replaced the Millstone Power Station Unit 2 Reactor Vessel Closure Head (RVCH) with one that contains crack-resistantControl ElementDriveMechanism (CEDM) nozzles. The DNC project team seized this opportunity to develop an innovatively designed replacement head assembly upgrade package (HAUP), which significantly reduces the duration for reactor disassembly and reassembly while improving the overall safety of these activities.
