In hypothetical meltdown accidents of light water reactors (LWR's), it is expected that radionulcides released from the melt will undergo chemical and physical changes and will deposit on various surfaces as they are transported through the primary system to the containment. It is of considerable interest to know what fraction of these released nuclides actually reaches the containment and is available for leakage to the environment. A radionuclide transport and deposition model was developed that is consistent in its sophistication with the emerging state of knowledge regarding radionuclide release from core melts and the thermal-hydraulic behavior of LWR primary systems during meltdown. TRAP-MELT is a modification and further development of the previously published TRAP-LOCA code developed by us for analysis of fission product transport and deposition in a terminated loss-of-coolant accident.
