Investigation on sedimentation behavior of debris is important to evaluate the sequence of core disruptive accident in SFR. To clarify this behavior, a series of experiments was performed by gravity driven discharge of solid debris from a nozzle into a water pool. The discharged debris accumulates on the collector plate at the bottom, forming either a Gaussian-type convex or ring-type concave mound depending on the experiment parameters. Three types of spherical debris with three diameters are employed to study the effect of experiment parameters on mound height of debris bed. During the experiment, mound height becomes decreasing with nozzle diameter and increasing with debris volume, which exhibits descending tendency in asymmetrical fashion with density variation and an unalike variation in mound height was observed with debris diameter. An empirical model was developed applying dimensional analysis to predict the variation in mound height of debris bed during sedimentation process.

All the spent fuel stored in the Tokai Reprocessing Plant is transported to the overseas reprocessing plant. When spent fuel transportation, we use dry type cask instead of wet type cask. Therefore, equipment of the wet type cask is not used. And the equipment is some possibility of interfere with cask because the equipment is stored in the transport route. So, we were dismantled receiving and storage process equipment as preparation work for spent fuel transportation. In dismantlement work, we selected cutting equipment after scrutinizing size and shape of equipment, contamination and workability. Moreover, we have taken safety measures during work such as fire prevention and contamination control. As a result, the work was completed as originally planned.
