The tritium processing demonstration facility will have a capacity of only 400 cubic meters per day.
The project was first announced in February 2015, when RosRAO commissioned Atomproekt to design the water treatment plant and test with 48 cubic meters of simulated solution.
RosRAO and Atomproekt are subsidiaries of Rosatom, the Russian state nuclear corporation.
RosRAO is the national manager of spent fuel and radioactive waste in Russia.
Atomproekt is formerly known as VNIPIET (All-Russia Science Research and Design Institute of Power Engineering Technology), and designs nuclear projects, processing plants, and waste facilities.
