Unit cost and number of flexible containers for clean-up phase of decontamination for different method considered in the present analysis.

aNumber of flexible containers used to store contaminated wastes generated by removal phase. The volume of a container is assumed to be 0.9 m3 and the cost of a flexible container is assumed to be 8,000 JPY/unit.bThe cost of the temporary storage per flexible container is assumed to be 20,000 JPY/unit.c Obtained from Fukushima [10].d Obtained from JAEA [11]. For the decontamination cost for F1, the unit cost was estimated considering the slope angle of the area based on the report.
