Unit cost for storage phase of decontamination and total of all the unit costs considered in the present analysis.

aThree options are assumed for the interim storage: D1 assumes combustible waste to be subjected to volume reduction and different types of disposal for high-elution materials (isolation-type disposal) and low-elution materials (control-type disposal) are used. D2 assumes combustible waste to be subjected to volume reduction and isolation-type disposal for both high-elution and low-elution materials is used. D3 assumes no volume reduction and isolation-type disposal is used for all waste.bTotal consists of clean-up and storage costs.
