Timing and Structure

Lent Term. 16 lectures, 4 examples papers, 2 examples classes in support of coursework. Assessment: 100% coursework




The aims of the course are to:

  • provide an understanding of advanced systems, why they are being pursued, what their advantages are and their difficulties in becoming commercially viable designs.


Further aims:

  • What are the factors that are driving the development of advanced systems?
  • Overview of fast reactor development & Generation IV reactor systems, including accelerator driven sub-critical reactors;
  • Introduce the principles of fusion energy physics and the current status of research;
  • Explain how the principles of fusion energy are to be applied for the design of future fusion energy systems;
  • Re-cycle fuel studies, including reprocessing and re-fabrication;
  • Status, issues and what would be needed to bring advanced reactor systems to a commercial standard with safety and economics as good as current Generation III+ designs
