Goal(s)
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").
Content(s)
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.
Prerequisites
Pressurized Water Reactors : principle and main systems.
Neutronics
Thermohydraulics
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
note = 30%Prepa + 70%CR
