3.1. Value Function (VF) and Separative Work Unit (SWU)
VF for oil-water separation was determined based on the data from the hearing investigation as shown Fig. 4.
One litter of pure oil was processed by 25 JPY/L and sold by 150 JPY/L, and then the total price of oil was 125
JPY/L. The concentration of oil was determined as above 99.70% because oil with below 0.30% of water can be
sold as oil resource based on an empirical manner.
