Radiochemistry of iodine: Outcomes of the CAIMAN program

摘要

Iodine is a fission product of major importance because volatile species can be formed under severe nuclear reactor accident conditions and may potentially be released into the environment, leading to significant radiological consequences. The CAIMAN program was devoted to studying the radiochemistry of iodine in the reactor containment in the case of a severe accident occurring in a pressurized water reactor; this is a database of prime importance for the validation of codes, namely IODE, which is a module of the integral Accident Source Term Evaluation Code (ASTEC), jointly developed by the Institut de Radioprotection et de Surete Nucleaire and the Gesellschaft fur Anlagen- und Reaktorsicherheit. These computations are generally used to predict the radiological consequences of such an accident.
