The absolute amount of the test sample is required for the neutron capturing cross-section measurements. But the absolute amount has not been precisely determined for obtained samples. Therefore, it is necessary to determine absolute amount of samples accurately by nondestructively. This presentation will report for the future plan about the all deposit heat measurement from minor actinides samples in order to determine the absolute amount of samples non-destructively. This presentation is as part of nuclear system research and development project "R&D for accuracy improvement of neutron nuclear data on minor actinides".
