[H-CG36_29PM1] Nuclear Energy and Geoscience

Tue. Apr 29, 2014 3:15 PM - 4:00 PM 411 (4F)

Convener:*Koji Umeda(Tono Geoscience Center,Japan Atomic Energy Agency), Hidekazu Yoshida(Nagoya University Museum), Chair:Koji Umeda(Tono Geoscience Center,Japan Atomic Energy Agency)

Handling of geological hazard assessments represent a major environmental concern in the modern society due to constructing nuclear facilities and their radioactive wastes, and also related to the management of contaminated biosphere after nuclear disasters. The session rational is to provide a forum to deal with various aspects of seismic and volcanic hazards at nuclear facilities, radioactive waste disposal in subsurface storage facilities and dynamic behavior of radionuclides emitted from disabled nuclear plants. It covers the aspects of geology, geophysics, geochemistry and other related geosciences.
