Abstract
PFC(Perfluorocarbon) decontamination process is one of best methods to remove hot particulate adhered at inside surface of hot cell and surface of equipment in hot cell. It was necessary to develop a particulate filtration equipment to reuse PFC solution used on PFC decontamination due to its high cost and to minimize the volume of second wastewater. Contamination characteristics of hot particulate were investigated and then a filtration process was presented to remove hot particulate in PFC solution generated through PFC decontamination process. The removal efficiency of PVDF(Poly vinylidene fluoride), PP(Polypropylene), Ceramic(Al
원자력연구시설의 핫셀 내 바닥이나 장치표면에 부착된 고방사능분진의 제거를 위해서 PFC제염기술을 적용한다. 고가인 PFC 용액의 재사용을 위해서는 여과장치의 개발이 필요하고 제염종료 후 이차폐기물의 양을 최소화할 필요가 있다. PFC 제염폐액 내 방사성 입자를 제거하기 위해 핫셀 내의 고방사능분진의 오염 특성을 조사했다. 여과 막을 이용한 입자의 제거효율 측면에서 보면 세라믹 , PVDF, PP 막 모두가 95
