N17: Tritium and the Fusion Fuel Cycle

Aims

Provide students with the theoretical and practical knowledge needed to support the development of the fusion fuel cycle, with a particular focus on tritium and associated issues.

Brief Description of the unit

This course unit provides an introduction to nuclear fusion, and a detailed overview of the tritium science and technology that underpins successful operation of a future fusion power plant. It is specifically designed to provide an understanding of the fundamentals of the tritium fuel cycle as it pertains to the burgeoning field of fusion power plants. The unit consists of a brief overview (approximately 1 day) of the basics of nuclear fusion and fusion reactors, along with more details lectures covering key topics including fuel storage and supply, isotope separations (D, T, and He), tritium removal from water and waste forms, and personal and environmental protection. Included in the lecture series will be a guest lecturer from the UKAEA’s H3AT centre – a world-leading tritium science and technology facility. A small hands-on experimental component (1 day) will also provide valuable experience. A post-course tritium science and technology assessment designed to consolidate knowledge gained during the course and enable students to join industry with a solid understanding of key tritium science and technology issues and processes.

Intended Learning Outcomes

Describe and discuss the purpose and requirements of a nuclear fusion power reactor, giving examples of key sub-systems and the explain the fundamentals of the fusion reaction.

Compare and contrast breeder blanket options for fusion reactors, analysing the benefits and drawbacks for each type.

Interpret and explain the purpose of the fusion fuel cycle, and how fuel can be stored.

Identify the thermodynamic and kinetic characteristics of isotope separations; compare and contrast isotope separation techniques.

Describe the mechanisms of H isotope recovery from liquid and solid materials, and summarise how this may be used in detritiation of plant materials.

Explain and summarise methods and mechanisms to provide fuel cycle safety protection to personnel and the environment.

Write a coherent logically-argued technical report on a sub-system of the fusion fuel cycle, identifying the strengths and weaknesses.
