A study on boron permeate by reverse osmosis process for the application to the radioactive waste treatment system in NPP

To apply the reverse osmosis process for the permeate of boron contained in the radwaste generated from the NPP, the effectiveness and feasibility were studied through the fundamental experiments. The simulants with floor drain tank made of boron were used for the lab-test. The optimum boron permeate rates due to the operating pressure, pH, temperature, and boron concentration were investigated. The boron permeate rate tends to decrease with operating pressure but increase with temperature, boron concentration. when the pH was 5 and below, the boron concentration in permeate increased
