Operation and control

Objectives:

  • To learn how to operate a nuclear reactor
  • To learn the reactivity change of a reactor core during a burn-up cycle
  • To learn the basics of core reloading

Emphasis will be placed on PWR-technology

List of topics:

  • Variation of the core reactivity during a burn-up cycle (BOL-EOL) (temperature, Doppler and power coefficient; poisoning)
  • Methods of control of the reactivity change
  • Organisation of operating modes, operation and protection diagrams, Xe oscillations and their control
  • Organisation of operation and maintenance, interruption, surveillance and incidents
  • Operational constraints imposed by the electric net: regulation of steam cycle
  • Automatic control systems and their performance in transient and steady state operation
  • Evolution of the fissile and fertile composition of the core during a cycle and their impact on core behaviour
  • Plutonium production and MOX recycling
  • The basic principles of core-reloading

Amplitude and teaching methods:

  • 1 t.m.
  • Visit of a nuclear power plant during reloading operations
  • Practical exercises with a simulator
  • 1 day demonstration with codes for reload operation and core evolution
