Overview of Defueling Approaches used to Deal with Reactors that Have Major Core Damage
In decommissioning a normal nuclear power plant whose fuel and/or reactor internals have not experienced some type of damage, one is working with a reactor that is still an engineered product—the dimensions of the structure and equipment are known, the materials and their condition are known, the physical arrangement of the reactor internals and fuel assemblies are known and are within their original design parameters, radiation levels and the degree of contamination are within known bounds, etc. In such situations, the de fueling and core removal portion of the decommissioning operation can rely on normal refueling equipment and procedures. Such operations are straight-forward and well proven.
