Relocation of zircaloy-clad uranium dioxide under severe accident conditions

Conference ·
OSTI ID:7124620
The mechanisms affecting the relocation of zircaloy-clad UO/sub 2/ fuel rods during severe accidents in pressurized water reactors are discussed. Results from two integral in-pile tests and from the damaged Three Mile Island Unit-2 reactor core are presented. The thermal hydraulic conditions that influence fuel relocation are identified and chemical interactions between the fuel and the control rod material are addressed as they relate to material relocation.
