Post-accidental physical phenomena


Advanced training to analyze post-accident thermal-hydraulic phenomena, including a unique real-time visualization of what is really happening in the vessel and loops.

Training description:

This course studies post-accidental thermal-hydraulic phenomena and is tailored for PWR operation and nuclear safety personnel. The main goals are to justify the design of systems and components and to better understand operator actions in abnormal situations.

The SIPACT interface gives trainees access to fundamental values and teaching diagrams that are not available in a PWR control room and this is what makes this training unique.

Thermal-hydraulic basics are applied to the main operation accidents: loss of coolant, steam generator tube rupture, secondary side depressurisation, and total loss of feed water. Various parameters are taken into account: break size and location, fuel cycle, plant state, and long-term issues especially for boron concentration... A specific session on the impact of the mass, volume, and energy balance on the primary pressure is also included.

Course information:

Pre-requisites: Reactor operator qualification

Learning techniques:

  • Classroom lectures to reinforce knowledge
  • MISTRAL simulator training giving opportunities to practice and work in pairs
  • SIPACT and MISTRAL allow to play trial and error, really helping the trainee to focus on knowledge with a high degree of freedom of operation. The tools help to give meaning to procedural actions, to see what happen if the operator does the correct action or if he does it wrong.

Target population: Nuclear operation and engineering personnel

Duration: 1 week at an EDF training center

Max number of trainees per course: 8
