Abstract
The nuclear accident of the Fukushima Daiichi Nuclear Power Plant, followed by the Great East Japan Earthquake on March 11, 2011, caused high radioactive release which resulted in serious environmental contamination. While efforts to restore the environment by decontamination and disposal of The soil and waste removed in off-site decontamination work have continued, Japan has to address as much as 14 million cubic meters of removed soils and removed soil and waste, The Ministry of Environment has prepared interim storage facility to have removed soil and waste managed and stored in a safety and concentrated manner, which are transported from Temporary Storage Sites. Those removed soil and waste are to be transported outside Fukushima Prefecture for final disposal. The Ministry of Environment has had a large volume of removed soil and waste, which were temporarily stored in temporary waste sites in Fukushima prefecture, transported to Interim Storage Facilities. This has required up to 1,700 large dump trucks (for a total of approximately 3,200 round trips) per day. The transportation has therefore raised concerns about heavy traffic and road congestion involving general vehicles due to those trucks in operations. The problem has been particularly serious for the areas surrounding Interim Storage Facilities where tend to be congested with vehicles. Our study, to solve this problem, estimates the impact of transportation of removed soil and waste on traffics, proposes transportation plans, report cases of the achievement acquired thorough our transportation management (by PDCA cycle) and provides future challenges to be addressed.
