For upgrading the neutron beam facility of the JRR-3, neutron guides are planned to be installed close to the liquid hydrogen moderator, therefore a temperature rise of the neutron guide by nuclear radiation heating is expected. It is known that the performance of a neutron supermirror is degraded by heating. In order to investigate the influence of heating on the performance of the neutron supermirror, reflectivity profiles of the heated multilayer mirrors which were coated by ion beam sputtering technique were measured. Thickness of diffusion layer and interface roughness were analyzed by using these reflectivity profiles. It was found that the thickness of the Ni/Ti multilayer mirror was reduced by 2% and the intensity of the first Bragg reflection was reduced to one third at 443K by using X-ray reflectometer.

Clarification of aging phenomenon of fuel debris is one of the important issues because to evaluate that the safety during long term at defueling and storing. As a physical mechanism, we were investigated the effect of environmental temperature on the amount of cracks increased, and clarified the behavior of crack generation and propagation in submerged fuel debris.
