An overview of the TMI-2 core examination plan

The TMI-2 Core Examination Plan presents a logical organization for the sampling, examination, and ultimate utilization of the data made available from the recovery program of the TMI-2 Nuclear Plant. The plan emphasizes cooperative efforts not only between the defueling team and those dedicated to the analysis of the data but also among the various laboratories and commercial facilities participating in the program. Dealing with the defueling sequence the core examination addresses three basic objectives; understanding severe core damage initiation, propagation, and termination; supporting the technical basis for existing regulation; and improving LWR design and operation. The mere understanding of the March 1979 accident mandate fundamental reasons for examining the TMI-2 core. During all phases of the recovery effort the plan intends to utilize the information used to assist the actual defueling operation.
