Study on Concentrating Treatment Test of Simulated Radioactive Wastewater Containing Boron by Reverse Osmosis Membrane in PWR NPP

The reverse osmosis membrane equipment in PWR NPP was employed to investigate the application of pilot scale system in the radioactive wastewater treatment at the full recirculation operation.The removal performance of the equipment for the boron and the radioactivity nuclide were studied, respectively. The experimental results show that the removal efficiency of the aromatic polyamide composite reverse osmosis membrane for boron is over 83.3% and the concentration of boron in concentrate is over 10 000 mg/L. The experimental results also show that the removal efficiency of two nuclides including cobalt and cesium is over 97.9%.
