Description
Contaminated material (soil/waste) generated from the decontamination of large contaminated areas surrounding the Fukushima Daiichi Nuclear Power Plant is being collected and stored at temporary storage facilities at all municipalities in Fukushima prefecture. The contaminated material will be transported to centrally-located Interim Storage Facilities (ISF) where it will be sorted, treated, and then placed for interim storage for up to 30 years. The current estimated volume of material that will be processed at the ISFs is 28 million m3 and effective technologies to help volume reduction are expected. Following acceptance inspection at ISF, contaminated material will be pretreated, i.e. segregated with regard to combustibility and radioactivity concentration. Such pretreatment work with enormous volume material is a key for early and safe implementation of interim storage. Obayashi Corporation has developed a series of automated pretreatment technologies which contributes to prompt operation, worker’s safety and volume reduction.
