SUMMARY
Monticello Nuclear Generating Plant (MNGP) underwent a replacement steam dryer (RSD) program during the spring 2011 refueling outage. MNGP replaced the original equipment manufacturer (OEM)steam dryer with a Westinghouse design.IC I IC In summary, the modeling features included in ACE Rev. 1.0 are the following:
