Development of Decommissioning Engineering Platform Based on Plant 3D Model
The Japanese government has begun decommissioning all nuclear reactors that are more than 40 years old. Decommissioning nuclear power
plants takes as many as several thousand workers, 10 years, and a cost of JPY 36 to 77 billion per reactor. The objective of this project is to
accurately calculate the amount of waste materials that must be managed as radioactive substances for each nuclear power plant.
Hitachi-GE Nuclear Energy assessed the radiation dose for workers, the number of man-hours and amount of radioactive waste materials
generated from demolition, demolition procedure data, and residual radioactivity with the help of 3D models in MicroStation – establishing a safe,
rational plan for demolition that will be used in the future planning of decommissioning projects. By the 2040s, decommissioning will peak at more
than 50 percent of domestic plants.
