Japan Atomic Energy Agency has been investigated the groundwater chemistry on excavating the underground facilities as part of the Mizunami Underground Research Laboratory (MIU) Project at Mizunami, Gifu, Japan. This report compiles data of the groundwater chemistry obtained at MIU in the fiscal year 2011. In terms of ensuring traceability of data, basic information (e.g. sampling location, sampling date, sampling method, analytical method) and methodology for quality control is described.

Japan Atomic Energy Agency has been investigated the groundwater chemistry on excavating the underground facilities as part of the Mizunami Underground Research Laboratory (MIU) Project at Mizunami City, Gifu Prefecture, Japan. This report compiles data set of the groundwater chemistry obtained at MIU in the fiscal year 2010. In terms of ensuring traceability of data, basic information (e.g. sampling location, sampling date, sampling method, analytical method) and methodology for quality control is described.

Times Cited Count:109 Percentile:98.65(Materials Science, Multidisciplinary)Experiments were conducted on simultaneous recovering of uranium and plutonium electrochemically into laboratory scale liquid cadomium cathodes(LCCs) at different U/Pu ratios in the salt phase. The influence of the salt composition on the recovered amount of uranium and plutonium, the morphology of uranium and plutonium in the LCCs, and the behavior of americium were examined. It was shouwn that there is a threshold in the U/Pu ratio in the salt phase for the successful simultaneous recovery of uranium and plutonium up to 10wt% in high current efficiencies.

An electrolytic reduction process of oxide fuels has recently been developed, however it was found that the behaviors of rare earth elements and zirconium are expected to be complicate because their oxides are stable and complex oxide compounds may form. After Fukushima- Daiichi reactor accident, studies on applicability of pyrometallurgical process to damaged fuel debris consisting of ZrO-UO
have been started. In this study, reduction behaviors of ZrO
, ZrO
-Li
O and ZrO
-UO
were investigated. It was proved that ZrO
can be reduced to metallic form in LiCl melt and that ZrO
easily reacts with dissolved Li
O to give Li
ZrO
. After ZrO
is converted to Li
ZrO
, zirconium metal is hardly obtained even in a LiCl melt with low Li
O concentration.

Zirconium dioxide formed complex oxide like LiZrO
or Li
ZrO
according to the concentration of Li
O in the LiCl-Li
O melt. It was clarified that ZrO
could be reduced to metal and formed lithium zirconate was difficult to be reduced by electrolytic reduction operations.

The MA recovery process by dry process was studied for partitioning and transmutation scenario. We measured equilibrium separation factor by the experiments of reduction extraction using liquid Ga/Al and chloride molten salt. The experimental results, as compared with the case of using a liquid Cd, high separation efficiency for the rare earth element was obtained.
