Abstract:

A database for transmutation and radioactivity of nuclear materials under neutron is important in view of selection and design of materials for various nuclear reactors. A database based on the FENDL-II on the Internet and additional data collected from several references has been developed on the NRIM ``Data-Free-Way'' site on the Internet. A user interface has been constructed for retrieval of necessary data and for graphical presentation of the relation between the energy spectrum of the neutrons and the neutron capture cross section. The possibility of chemical compositional change and radioactivity in a material caused by nuclear reactions can be easily retrieved using a browser such as netscape or explore, though the evaluation is qualitative.
