CSARP is an international program on severe accident phenomenological research and code development activities organized by the NRC since 1988. The objective of CSARP is the exchange of data and analyses on experimental and analytical research on severe accidents. The NRC coordinates CSARP activities with participation from more than 25 member nations that focus on the analysis of severe accidents and their consequences using state-of-the-art computer models. The NRC developed the MELCOR code for modeling accident progression, and the MELCOR Accident Consequence Code System (MACCS) to evaluate offsite consequences from a hypothetical release of radioactive material into the atmosphere.
