알파분광분석법에 의한 237Np 정량 및 사용후핵연료 시료에의 적용
Electrodeposition of 237Np for Alpha Spectrometry and Application to Spent Nuclear Fuel Samples
Abstract
Alpha spectrometry was studied for the determination of in spent nuclear fuel samples. The optimum condition for the electrodeposition of was obtained as follows : for hour of deposition time, at the current intensity of A and at sodium sulfate electrolyte without organic additive. The deposition yield and its reproducibility on was decreased as the amount of decreased from 4.16 Bq down to 0.0264 Bq(1ng). The recovery yield of determined by alpha spectrometry after separation in synthetic solution was (n=4). The contents of in spent nuclear fuel samples were determined and the result showed an agreement within 10% of a difference between the measurement and the calculation.
