[1C06] Development of treatment for low radioactive waste in Tokai Reprocessing Plant
(31) Study on cement solidification in full-scale kneading
Keywords:Tokai Reprocessing Plant, LWTF, low radioactive effluent, cement solidification
The Low Active Waste Treatment Development Facility (LWTF) at the Tokai Reprocessing Plant (TRP) is a facility to treat low radioactive liquid and solid wastes generated from the reprocessing plant. The liquid wastes to be treated at the LWTF are low radioactive concentrated liquid waste and phosphate liquid waste, which are planned to be cemented solidified. The low radioactive concentrated liquid waste will be separated into slurry liquid waste and carbonate liquid waste by the existing nuclide separation facility and the newly constructed nitrate root decomposition facility, and then cement solidified. Currently, studies and designs are underway for the introduction of a nitrate root decomposition facility and a cement solidification facility.
This report describes the results of full-scale kneading tests for cement solidification, which confirmed that the carbonate, slurry, and phosphate wastes hardened by the next day, did not generate floating water, and had sufficient compressive strength.
