Transport of radionuclides for safe and secure radioactive waste management by integration of chemistry with physics
Despite any nuclear energy policies taken by government and utilities, the issue of management and disposal of used nuclear fuel is essential and critical for public acceptance of the policies. Without safe and secure radioactive waste management, the public and our society never accept nuclear energy.
In order to increase the confidence of Canadians and global societies in radioactive waste management, we are elucidating the sorption, diffusion and transport of key radionuclides in the final repository, geosphere and biosphere by integrating the chemical experiments with physical chemistry and quantum dynamics.
We are the only research group in Canada researching this area. We are collaborating with the Nuclear Waste Management Organization of Canada (NWMO), Lawrence Berkeley National Laboratory, the the Helmholtz-Zentrum Dresden-Rossendorf and the University of Tokyo. Our research achievements will be used in the safety case studies of NWMO, other implementers and regulatory authorities in the world.
New risks and uncertainties in safety and security of waste management from Small Modular Reactor
Canada is taking the initiative of deployment of small modular reactors (SMR) in the world. However, there are few (or no) discussions of new risks and uncertainties by SMR in the nuclear fuel cycle and radioactive waste management.
We are studying the optimized SMR deployment in Ontario and Canada by mathematical models and identifying, analyzing and managing what types of risks and uncertainties have to be taken into account from inventories and compositions of radionuclides to economic, political/societal and environmental aspects quantitatively and semi-quantitatively.
Nuclear fuel cycle and radioactive waste management with social scientific literacy
There are many questions which can be asked of science and yet which cannot be answered by science. Nuclear fuel cycle and radioactive waste management are the typical subjects of so-called “trans-science”. By collaborating with social scientists and considering non-natural scientific and engineering knowledge such as Indigenous wisdom, we are examing how nuclear fuel cycle and radioactive waste management should be positioned in Canadian and global communities in the post-truth era. Examples of research are (i) the responsibility of nuclear engineers in nuclear engineering education and (ii) the Disposal safety assessment index consistent with indigenous values.
