원자력발전소에서 사용되고 있는 증발기에 대해 boron의 탈비말 동반을 분석하기 위하여 강제순환식 및 반연속식 증발기가 실험에 사용되었다. 보수가 용이하고 제염효율이 높은 Cyclone과 glass-wool 충전탑을 액체방사성폐기물을 처리하는데 탈비말동반장치로 사용되었다. Cyclone과 glass-wool 충전탑을 연결하여 사용하였을 때 붕소에 대한 제염효율은 1,000 이상을 나타내었다.
The purpose of this research was to investigate the de-entrainment of boron for evaporators used in nuclear power plants. The forced circulation and semi-continuous type evaporator was used in the experiment. Cyclone and glass-wool packed column which is supposed to provide good decontamination factor as well as easy maintenance, were selected as de-entrainment devices to be used in the evaporation of radioactive liquid wastees. The de-entrainment device combined with cyclone and glass-wool column has shown overall DF more than 1, 000 for boron.
