Content (Syllabus outline)

Radioactive waste, irradiated fuel waste from nuclear fuel cycle:

  • Sources of radioactive wastes
  • The types of radioactive waste
  • irradiated and spent fuel - Pre-processing and processing of radioactive waste.
  • open and closed nuclear fuel cycle, waste from other sources). - Preparation of radioactive waste.
  • Storage of radioactive waste. - The management of spent nuclear fuel before disposal (processing, storage). - From the waste to the suspension (research, site selection and characterization, underground laboratories, administrative procedures). - Disposal of radioactive waste and spent fuel and disposal technology.
  • Assessing the performance of the landfill and the safety analysis. - Transport of radioactive waste and spent fuel. - New technologies for the management of spent fuel (partitioning and transmutation)
  • Reuse of irradiated materials .
  • radioactive material as future resource
    Decommissioning of Nuclear Facilities:

  • Basic concepts and requirements of decommissioning. - Decommissioning methods and technologies.

  • Radioactive waste from decommissioning. - Decommissioning program and execution. - Examples

Objectives and competences

Objectives: To acquire basic knowledge about radioactive waste, spent fuel, and decommissioning of nuclear facilities. To become familiar with arrangements and processes for the safe management of radioactive waste and spent fuel management and decommissioning of nuclear facilities. To recognize specific examples of safe management of radioactive waste and spent fuel from generation to permanent disposal and decommissioning of the nuclear facilities. To develop a responsible attitude towards environment and society in the field of radwaste management.

Intended learning outcomes

Knowledge and understanding
Understanding of the basic principles of radioactive waste and spent fuel. Understanding of the requirements and constraints derived from the safety analysis.
Understand difference between final repository and storage. Understand the difference between waste and future resources.
To know and to understand the basic principles of nuclear decommissioning.
Knowledge can be used directly in practice for the management of radioactive waste and the decommissioning of nuclear facilities.
An example of the use of similar principles of a responsible attitude with other types of waste (toxic waste), for the planning and execution of process for other environmentally hazardous facilities and industrial plants in general.
Transferable skills
Principles of radioactive waste are the same and are applicable in all stages of the nuclear fuel cycle. Waste management and decommissioning of nuclear facilities receive significant weight in the development and design of new nuclear technologies and a new generation of reactors.
