Radioactive Contaminants and Waste Management in the Environment (#390)

Contamination of the environment due to radioactive wastes from weapon production, nuclear power generation, spent nuclear fuel process, and nuclear power plant accidents, such as the Fukushima disaster, is a major concern. Of particular concern is that many of these radioactive wastes do not have perfect solution and a disposal pathway yet. Also, if these radioactive wastes enter the environment, many radionuclides pose significant challenges to remediate. Multidisciplinary understanding of radiochemistry, geochemistry, hydrogeology, nuclear engineering, and environmental engineering is required to resolve the environmental problems related with radioactive wastes for remediation, stabilization, retardation, storage, and transport of radionuclides in the environments. This symposium will focus on environmental, radiochemical, and geochemical factors that influence behavior of radionuclides in various wastes and contaminated environments. It will especially address the multidisciplinary approaches undertaken in 1) the management of low-, intermediate-, and high-level radioactive wastes, 2) fundamental chemical and biogeochemical processes affecting the radionuclide speciation and mobility in the environment, and 3) the state-of-the -art engineering strategies for waste immobilization and disposal in radioactive waste repository.
