academic year
2025-2026

Course teacher(s)

Pierre-Etienne LABEAU (Coordinator)

ECTS credits

5

Language(s) of instruction

english

Course content

Introduction to the physics of nuclear reactors, transport equation, overview of solution methods (discretization methodes, elements of Monte Carlo simulation), diffusion approximation, multigroup model, criticality, point kinetics, diffusion and neutron slowing down, Doppler effect, resonance integrals, reactivity control.

Objectives (and/or specific learning outcomes)

Understand the physical concepts underlying how a nuclear reactor works. Model the evolution of the neutron population in a reactor. Understand the associated numerical methods.

Prerequisites and Corequisites

Required and Corequired knowledge and skills

Mathematics and physics expected at the end of a bachelor in engineering

Teaching methods and learning activities

Oral lectures + tutorials.
Oral lectures with powerpoint support aiming to emphasize on the physical interpretation of the mathematical modeling. Tutorials allowing to use the concepts developed during the lectures, and presenting simplified reactor design problems.

Seminars given by industrial collaborators:
* General introduction on how a nuclear plant (mainly a pressurized water reactor, PWR) works.
* Introduction to fast nuclear reactors.
* Introduction to SMR (Small Modular Reactors)

 Bibliographical project realized in small groups on a topic based on the concepts seen in the course.

The exam (written for the 1st session, potentially oral for the 2nd session if the number of students is limited) covers both theory and exercises. A group project is done at the end of the course.
A first part of the exam, in closed-book format, covers the theory of the first 6 chapters. A second part, in open-book format, consists of questions of reflection and understanding on the whole course, as well as exercises.

Mark calculation method (including weighting of intermediary marks)

Theory (closed-book) 40%, project 10%, questions of reflection and exercises 50%
