Harmonization and Intercomparison of Models for Accidental Tritium Releases to the Atmosphere

Harmonization and Intercomparison of Models for Accidental Tritium Releases to the Atmosphere Synopsis

This publication has been produced as part of the IAEA's Modelling and Data for Radiological Impact Assessments (MODARIA) programme. It summarizes the activities of Working Group 7, which was one of ten working groups within MODARIA, and focused on the harmonization and intercomparison of models for the accidental release of tritium to the atmosphere. It addresses the modelling of tritium into the atmosphere and the subsequent terrestrial processes that determine the dynamic transfer of tritium in the environment. The first half of the report contains a literature review regarding state-of-the-art modelling of tritium in the terrestrial environment. The second half summarizes the results of an intercomparison exercise undertaken using four models to inform the direction of future research.
