Abstract

The second version of WSPEEDI (WSPEEDI-II) is developed. It has functions to predict the radiological impact of nuclear accident abroad on Japan by quick calculations of air concentration, surface deposition, and radiological doses. WSPEEDI-II has the following new functions for better predictions and practical use: (1) high-performance prediction of atmospheric dispersion of radionuclides from local to regional ranges with appropriate resolutions by introducing a nonhydrostatic atmospheric dynamic model, (2) source term estimation by coupling calculation results and monitoring data for the case that no source information is available from abroad, (3) on-line prediction data exchanges with major emergency response systems in the United States and Europe having similar functions to WSPEEDI-II, (4) web-based graphical user interface system for easy operations of WSPEEDI-II, and (5) preset East-Asian database for quick start against a nuclear accident in Eastern Asia. In this paper, we describe these new functions of WSPEEDI-II. © Atomic Energy Society of Japan.
