Abstract

In order to monitor a rotating cylindrical separator for radioactive waste, an electrical resistance method is proposed and its mathematical model is investigated. In a rotating radioactive waste separator, the electrical resistance between a pair of electrodes mounted on the inner wall of the vessel is related to the thickness of annular region of insoluble particle formed around the periphery and the concentration of the insoluble particle in that region. This work presents an analytical relationship among the aforementioned parameters based on a two-dimensional solution to the electrical potential equation and an empirical conductivity-concentration relation. Also, the feasibility of electrical resistance method for monitoring rotating cylindrical separators is discussed.

본 연구에서는 방사성 폐기물을 처리하는 원통형 회전 분리기를 감시하기 위해 전기 저항법을 제안하고 수학적 모델을 연구하였다. 회전형 방사성 폐기물 분리기에서 관 벽에 설치된 한 쌍의 전극의 전기 저항은 표면을 따라 형성된 불용해성 입자의 환상 영역의 두께와 그 영역의 불용해성 입자의 농도와 관련이 있다. 본 연구는 전위 방정식에 대한 2차원 해와 실험적인 전도도-농도 관계를 기반으로 전술한 인자들 사이의 해석적 관계를 기술하였다. 또한, 원통형 회전 분리기를 감시하기 위한 전기 저항법의 적용 가능성을 논의 하였다.
