The objectives of this course are to show :

  • the physics of the core behaviour iand in particuld'une part, d'illustrer la physique du coeur, en particulier le couplage neutronique - thermohydraulique (coefficients de température Doppler et modérateur), à travers différents phases d'exploitation d'un réacteur,
  • the system as a whole is reactor is studied with all the complexity of the links between the nuclear core and the power grid.

Those at different states of the reactor operation :

  • at "zero" power, i.e. without thermal feedbacks,
  • before the coupling to the grid ("core driven"),
  • after the coupling to the grid ("turbine driven").

The course is based on the use of the numerical simulator SIREP 1300MW of CORYS.

  • Lab 1

Sub-critical approach, divergence, power stabilization,
Search of Point Of Added Heat (power level where thermal feedbacks appear), temperature feedback coefficients measurement

*Lab 2

Evaluation of the worth of core controls : Boron, control rods,
Power ramp up before grid connection ("core driven"), use of main systems for heat exchange.

*lab 3

Power ramp up after grid connection ("turbine driven"), behavior without core control by the operator,
Load following : temperature program, axial offset, core controls.

The simulator is very easy to use.
A text book is available.


Pressurized Water Reactors : principle and main systems.
Two-phase thermodynamics
Nuclear Reactor Kinetics


evaluation is based on

  • written preparation (Prepa)
  • final Report (CR)describing
  • the evolution of key parameters during simulated transients
  • simple modeling of those transients demonstrating the understanding of the most important phenomena
