Data for estimating potential radiotoxicity of spent nuclear fuel

The potential radiotoxicity of spent nuclear fuel from nuclear power plants is defined as a summation of dose of individual nuclides in case of intake. In the present data base, the dominant nuclides for the potential radiotoxicity were selected from radioactive nuclides in the spent fuel, and dose coefficients to be used to convert radioactivity to dose were tabulated for the selected nuclides. Moreover, time evolution of the potential radiotoxicity was listed taking progenies into account for each actinide. The database enables simple estimation of time evolution of the potential radiotoxicity using an initial weight composition of the spent fuel. The potential radiotoxicity of a spent fuel from the light water reactor is shown as an example of the estimation. The database includes nuclides originated in the spent fuel and does not include those from decommissioning of the nuclear and allied plants. (author)
