One of the methods used to separate stable isotopes is the thermal diffusion column. In this research, the R cascade is used for designing and determining the number of columns to separate two Ne stable isotopes. Accordingly, all cascades that have enriched Ne isotopes to more than 99% are investigated. In this regard, a calculation code entitled “R CASCADE” has been developed. The unit separation factor is considered to be 3 and the number of stages varies from 10 to 20. The results show that the column separation power, the relative total flow rate, and the required columns are linearly related to the number of stages. The column separation power and the relative total flow decrease as the number of stages increase. In contrast, the number of columns are increased. Therefore, the cascade by 10 stages and 85 columns is recommended for separation of Ne stable isotopes.
