A large amount of nitrate in the effluent occurring from the Tokai reprocessing plant might cause the environmental pollution. The effluent is planning to be encapsulated by cement after treated in the nitrate ion decomposition process using a reductant and catalyst. Cement based encapsulation trials for low-radioactive effluent from the nitrate decomposition process is reported.
