Module aims

This module provides a basic introduction to the reactor physics of nuclear reactors, including neutron conservation, neutron diffusion, criticality for spheres cylinders and cuboids, reflected spheres, point kinetics with delayed neutrons, xenon poisoning, and other reactivity feedback mechanisms.

Learning outcomes

On successfully completing this module, students will be able to:

  1. Perform basic reactor physics algebraic analysis and numerical computations, including solutions of the neutron diffusion equation, and the assessment of criticality for the principal reactor geometries.
  2. Derive and use simple point kinetics models of reactor transient behaviour.
  3. Explain the role of neutron reflectors, and an ability to perform analyses of simple reflected geometries.
  4. Explain the significance of reactive feedback, and perform calculations and analysis of this in the case of xenon poisoning.
