Verification of Reverse Osmosis Technology for Treating Primary Coolant in Temelín Nuclear Power Plant

Original language description

Drained primary coolant from nuclear power plants containing boric acid is currently treated in the system of evaporators and by ion exchangers. Their operation is expensive, therefore other alternatives are examined, e.g. reverse osmosis. Using reverse osmosis, the feed primary coolant is separated into two output streams: retentate and permeate. Retentate stream consists of concentrated boric acid solution together with other components, while permeate stream consists of purified water. A pilot-plant unit of reverse osmosis was tested in Temelin nuclear power plant. It was installed in the Special Purification System SVO-6 for the regeneration of boric acid. Three experimental tests with real primary coolant of various composition and total radioactivity were performed across a wide range of feed primary coolant pH and with various total flows through the membrane modulus and recoveries (ratio of permeate flow rate to feed flow rate). During the tests, samples of output streams were taken and analysed for chemical parameters (conductivity and H3BO3, NH3, K and Li concentrations) and radioactivity parameters (total radioactivity and radioactivity and concentration of Cs-134 and Cs-137 isotopes). The aim of the tests performed in Temelin nuclear power plant was to verify possible use of reverse osmosis for the treatment of primary coolant, i.e. to obtain a concentrated solution of boric acid in the retentate stream and permeate stream pure of boric acid.
