The elemental composition of the structural materials of nuclear reactor facilities is used as one of the important parameters in activation calculations that are evaluated when formulating decommissioning plans. Regarding the elemental composition of aluminum alloys and other materials used as structural materials for test and research reactors, sufficient data is not available regarding elements other than the major elements. For this reason, samples were collected from aluminum alloy, beryllium, hafnium, and other materials that have been used as the main structural materials of JMTR (Japan Materials Testing Reactor), and their elemental compositions were analyzed. This report summarizes the elemental composition data of 78 elements obtained in FY2023.

Times Cited Count:4 Percentile:31.06(Chemistry, Analytical)To investigate the effect of weather on the composition of the dust and the possible origin of the dust, the elemental composition airborne dust was determined by INAA. The analyzed elements could be classified into 3 groups by the variation of concentration in the samples. The difference in concentration pattern may reflect the effect of rainfalls.
