Sensitivity study for the radionuclide inventory in the decommissioning of a light water reactor plant

Okumura, Keisuke; Hagura, Hiroyuki; Kojima, Kensuke; Yamamoto, Kento; Tanaka, Kenichi*

no journal, , 

A method of the activation sensitivity analysis was developed for the optimization of the inventory evaluation of radionuclides in the waste generated in the decommissioning of LWR plants. By applying the method to a BWR plant, we clarified the impurity nuclides in the structural materials and their nuclear reactions contributing the generation of about fifty radioactive nuclides important for the processing and disposal of radioactive wastes.
