| Outline and Purpose of the Course | Various wastes are generated from the use of nuclear energy, one of the key technologies to overcome the global warming, and the associated industrial activity. This course is inended to understand the type and origin of radioactive wastes, as well as the management, treatment, and final disposal of these wastes, from the viewpoint of environmental engineering. | |||
| Course Goals | By providing the students with the knowledge on various radioactive wastes generated by the use on neclear energy as well as the radiological risk of such wastes, the course will enable the students to consider the future of nuclear industries based on their own judgement. | |||

Course Introduction ,1time,Course Introduction Nuclear disaster action program,1time,uclear disaster action program Nuclear reactors,1time,Nuclear reactors Treatment of liquid radioactive waste,1time,Treatment of liquid radioactive waste Treatment of gaseous and solid radioactive waste,1time,Treatment of gaseous and solid radioactive waste Legislation of radioactive wastes,1time,Legislation of radioactive wastes Decomissining and clearance,1time,ecomissining and clearance Radiological risk,1time,The risk of radiation exposure, history of radiation dose limit set by international organizations, and dose limit under different situations are discussed Fukushima Daiichi Nuclear Power Plant (F1) accident and nuclear disaster prevention,1time,Discuss the relation between the events in F1 and the radiation dose in the environment as well as pollution of environment. The evacuation activity conducted in Fukushima and the related lessons are summarized. Problems of designated waste,1time,In the aftermath of the F1 accident, municipal solid waste contaminated with radioactive cesium has been produced in 12 Prefectures, some of these wastes were classified as designated wastes (DSW). The concept of DSW is compared with that of conventional radioactive wastes. Geological disposal of high level radioactive wastes (HLW) and the safety assessment ,1time,Inventory, the method of disposal (critical path and nuclides), philosophy of radiological protection, etc. are discussed. Behavior of radionuclides in the environment and mathematical modeling of nuclide migration,1time,Behavior of radionuclides in the geosphere has governing effect on the safety of geological disposal of HLW. The behavior based on the chemical characteristics of each nuclides and mathematical modeling of their behavior are discussed. Behavior and qualitative/ quantitative analysis of radionuclides in the environment,1time,Behavior and qualitative/ quantitative analysis of radioactive Cs, Co, Sr, I, Se, U, Pu and Ra in the environment, and events of radioactive pollution of the environment in the past, are introduced. The risk of radiation and the society,1time,After the F1 accident, the risk of radiation has drawn intense attention from citizens. The risk communication methodology to facilitate the understanding of radiation is discussed. Discussion with /between students,1time,Discussion on issues such as lifestyle in the contaminated environment (under existing exposure situation), whether residents should return to the contaminated areas, and how to deal with siting problems of final disposal of HLW, etc.. |
