The subject is focused on getting the knowledge on the system of radioactive waste and spent fuel management system, from the waste formation to their disposal to repository. Waste management subjects to licensing by Atomic law, what is a determining factor to the possibility of using different ways of waste management, i. e. collecting, sorting, treatment, processing, storage and disposal. Waste management in the Czech Republic and/or abroad is assured by more different technologies. To familiarize with these technologies is also a part of the subject.



Syllabus of lectures:

1. Formation and characteristics of radioactive waste.

Definition of radioactive waste and its formation. Classification of radioactive waste by the type of radiation, activity, half life and radiotoxicity of the radionuclides concerned. Physical and chemical properties of radioactive waste, thermal power and criticality. Sorting of radioactive waste. IAEA classification. Classification of using the way of management.

2. Radioactive waste management within the life cycle of energetic and institutional waste.

Life cycle of institutional and energetical waste. Front part of the fuel cycle. Nuclear reactors operation. Back part of the fuel cycle. Decommissioning. Institutional waste life cycle. Radiation sources life cycle. Waste management with the respect to the waste life cycle.
