Japan Meteorological Agency (JMA) and IRSN launched a Joint Research Program to better understand the kinetics and mechanisms of the ground deposit following the atmospheric radioactive releases due to the Fukushima accident of 2011. It is conducted as part of the Sakura Program of the Hubert Curien Partnerships (PHC), a Franco-Japanese cooperation in science and technology.
To advance its operational capabilities in case of radiation emergency, IRSN already conducted several research programs in modeling the dispersion of air masses contaminated with radionuclides.
The lessons learnt from the Fukushima accident will enrich IRSN’s existing knowledge, as well as knowledge of the JMA partner. Cooperation focuses on three related areas of modeling:
the quantities of radioactivity released during an accident,
the kinetics and the complex processes of ground deposition of radionuclides,
the uncertainties, especially related to weather conditions, concerning the assessments on which the measures to protect population in case of radiation emergency are based.
IRSN will benefit from the meteorological modeling capabilities of JMA and the synergies with Japanese researchers working on the Fukushima accident.
