Tezuka, Masashi  ; Sato, Yuji

On the progress of decommissioning of FUGEN, we are planning to transport the heavy water 240 m, and have dismantled the facilities about 400 ton. In dismantling, we have started dismantling of condenser, and will finish dismantling for four years. In insulation removal in early decommissioning stage, insulation separated from outer jacket is treated to volume reduction. In dismantling the base concrete, since it was the work in controlled are, we apply the method of diamond wire saw which is dry typed. We collected some cutting speed data, and it is important for us to take some steps against the much dust generated in cutting.
