In the metal electrorefining reprocessing method, transuranic elements (TRU) are recovered simultaneously with the liquid cadmium cathode (LCC) and are decontaminated from the fission products dissolving in the melt. Lab-scale experiments were carried out to evaluate the performance of TRU recoverly with LCC using U, Pu and minor actinides (MA), and it was confirmed that TRU could be recoverd simultaneously with LCC by electrode position.

It is considered that it is possible to avoid the effect of the uplift and denudation process on geological disposal system by siting and a repository design. However, since the uplift/denudation continues far into the future, it is important to enhance the confidence of the methodology to evaluate such an effect, based on the understanding of geohistorical information and potential impact on the disposal system. This paper presents an evolution pattern of the geological environment and the influence analysis in terms of system performance affected by the uplift and denudation process based on the relevant conceptual models for groundwater scenarios of the disposal system for a hypothetical sedimentary rock.

SPEEDI-MP has been developed for comprehensive prediction of migration of radionuclides in the atmosphere, ocean, and terrestrial region. In this study, we made attempt to distinguish the contributions to observed air dose rate between natural and artificial radionuclides from the reprocessing facility in Rokkasho, Aomori. For the purpose, two atmospheric dispersion models of SPEEDI-MP were applied, which were an Eulerian model for natural radionuclides and a Lagrangian particle model for artificial radionuclides. During the period of 10 September 2007, the model prediction performance was improved by using the observation data at the height of 250 m and 300 m above ground in addition to those from the surface to 150 m level for data assimilation in meteorological prediction. We could also generally reproduce the monitoring results observed at the monitoring stations approximately 4 km distant from the main stack in 12 September 2007 with the same calculation method.
