International workshop on dispersion and deposition modeling for nuclear accident releases -Transfer of science from academic to operational models- | ||
|
|
|
|
|
1. Scope |
Numerical models have
played a significant role in investigating the total amount and the transport
pathway for radio nuclides discharged from the Fukushima Daiichi Nuclear
Power Plant after The 2011 Great East Japan Earthquake. However, recent
studies of dispersion and deposition processes of radionuclides have revealed
that there are many uncertainties to be resolved in the simulation of
advection, diffusion, and deposition. The Workshop was planned for 2-4 March
2015 at Fukushima University to address these uncertainties. The first day of
the workshop was planned to focus on discussions to improve the models,
including both scientific research models and operational models for
radiological protection, the investigation of field observations in Japan,
and the planning of future research strategies. In addition to dispersion
processes, the operational emergency response systems include modules for
source term estimation, processing of observed data, and long term dose
estimation. The second day of the workshop was planned to focus on exchange
of knowledge of actual operating methods, as presented by international
participants from organizations operating the emergency response system for
nuclear facilities in their countries.
(Summary; the report of the workshop was submitted to Bulletin of American Meteorological Society (BAM, DOI:10.1175/BAMS-D-15-00191.1)) |
