The concentrated liquid waste of Fugen (ATR) is planned to be mixed and solidified using a cement mixing and solidification unit. In this facility, the concentrated liquid waste and cement as the solidification material, are mixed in the mixer and then filled into drums as the disposal containers, to produce a homogeneous and uniform waste package. The facility is being installed onsite with plans to begin service in 2026. This presentation reports on the overview of the solidification facilities and plans for putting it into service.

Waste packages are needed to satisfy the waste acceptance criteria (WAC) set by the landfill site. To produce sound waste packages that meet such criteria as uniaxial compressive strength and porosity, it is necessary to establish the range of parameters such as mixing time, rotation speed of mixing blade, and amount of cement. This presentation reports on the Beaker scale cold test conducted to determine the cement-to-waste ratio (C/W) which affects the number of waste packages produced and uniaxial compressive strength.
