The school intends to provide a complete perspective of fundamental aspects of nuclear waste management and disposal solutions and issues ranging from radioprotection to management issues and final disposal. The lectures will also encompass the norms and safety standards in the nuclear field, and the impact of nuclear activities on the environment and the population, including environmental radiation monitoring and risk and safety assessments for both the population and the ecosystem. The objective is to give to te students a right background allowing them to be fully engaged in the training session focused on post-closure safety assessment of nuclear waste disposal facilities. Starting from the the concept of a ‘safety case’ relating to radioactive waste disposal and its constituent parts the training sessione will cover all aspects of planning and managing nuclear waste and a disposal system. The objective is to provide a walk-through best international practice for post-closure safety assessment, signposting guidance and providing examples. This will include exercises in identifying scenarios and developing associated conceptual models and hands-on sessions with the AMBER compartment modelling tool. Students will be guided through running calculations, to exploring a model for near-surface disposal including wastes, the engineered facility, geosphere and biosphere, exploring results and making changes to explore scenario, model and parameter uncertainties.
Program Outline
The school consists of five days of different sessions with lectures in the in the following topics divided into three theoretical sessions and one practical session:
Session-1 (day 1): Radiation Protection and Safety in the Nuclear Field.
Participants will learn about radiation types, effects, and shielding. They will explore norms, safety standards, and licensing processes. Environmental protection, emergency preparedness, and ethical considerations are emphasized. Overall, they will gain comprehensive knowledge to ensure a safer and sustainable nuclear industry.
Session 2 (day 2): Nuclear Fuel Cycle and Waste Management.
Participants will learn the nuclear fuel cycle stages, including uranium mining, fuel fabrication, reactor utilization, and waste management, to gain a comprehensive understanding of the entire process. They will understand various types of nuclear waste and their hazards and conditioning treatment methods like vitrification and encapsulation for safe storage and disposal. Participants gain knowledge for responsible and secure nuclear waste management.
Session 3 (day 3): Temporary Storage and Final Disposal of Nuclear Waste.
Participants will learn about temporary storage facilities and safety considerations for holding radioactive waste. They explore the concept of near surface and deep geological repositories for permanent disposal, emphasizing isolation and the multi-barrier concept. The session covers international best practices, regulations, and ethical aspects. Participants gain insights into public engagement and transparent decision-making.
Training session (day 4-5): Comprehensive Post-Closure Safety Assessment, Compartment Modeling for Radioactive Waste Disposal and AMBER code hands-on.
Participants will learn about post-closure safety assessment of a radioactive waste disposal site and the compartment modeling approach using the AMBER code. Participants will learn the concept of a ‘safety case,’ including planning, managing, and radioactive waste and the disposal system, and also the compartment modeling methodology, applied to nuclear waste, repository, geosphere, and biosphere. Participants will have hands-on experience using the AMBER code to assess post-closure safety, exploring scenarios, model equations, and parameter uncertainties.

Course theme
The modelling of nuclear reactor systems is one of the most challenging tasks in complex system modelling, due to the many different scales and intertwined physical phenomena involved. The nuclear industry as well as the research institutes and universities heavily rely on the use of complex numerical codes, either commercially available or developed in-house. All the commercial codes are based on using different numerical tools for resolving the various physical fields, and to some extent the different scales, whereas the latest research platforms attempt to adopt a more integrated approach in resolving multiple scales and fields of physics.
Even though the sophistication of the codes allows for modelling intricate reactor phenomena, the complexity of the tools makes their use difficult. In addition, without proper guidance, users might apply the codes in some erroneous fashion, when for instance the underlying assumptions and conditions in a given numerical method are not fulfilled.
This course aims at presenting the main algorithms used in such codes. The course is not about explaining how to use such software, but rather to understand the underlying methods, together with their assumptions and limitations. After completing the course, the attendees will be able to use such codes with confidence.
The unique character of the course resides in tackling neutron transport, fluid dynamics, and heat transfer within the same course. The main techniques are presented in the course in a generic manner (i.e., not specific to any code system) and for practical reactor calculations performed by, e.g., utilities for core follow and safety analyses. Concerning neutron transport, the course thus focuses exclusively on deterministic modelling.
Learning objective
After completion of the course, the course attendees should be able to:
• Know the governing equations describing neutron transport, flow transport, and heat transfer in nuclear reactors.
• Know the modelling strategies used for neutron transport, flow transport, heat transfer in nuclear reactors, and for their coupling.
• Understand the limitations of the different modelling strategies.
• Implement some of the modelling strategies in modelling environments.
Target audience
• MSc students, PhD students and Post-Doc students having some background knowledge in nuclear engineering.
• Nuclear engineers.
• Reactor physicists.
• Nuclear safety analysts.
• Research scientists in the above fields.
Prerequisites
Although previous knowledge in reactor physics, thermal-hydraulics or nuclear engineering is definitely advantageous, all equations are derived from first principles and should allow the students not familiar with reactor modelling to comprehend all concepts thoroughly.
Some basic knowledge in programming is of definite advantage for solving different programming tasks. A web-based platform based on Matlab (called Matlab Grader) will be made accessible to the course participants. Basic programming skills in interpreted languages like Matlab or similar are beneficial. Participants not familiar with Matlab will be provided with extra resources.
Teaching approach
The course can be followed on-site in Chalmers or off-site (i.e., remotely).
The course follows a “flipped classroom” set-up in a hybrid (i.e., on-site/off-site) environment. Students learn asynchronously from a book, short video lectures and online quizzes prior to attending synchronous sessions (either in the classroom for the on-site students or remotely for the off-site students). Such sessions are held in an interactive teaching room in Chalmers. The room allows mixing on-site students with remote attendees while preserving full interaction possibilities between both audiences. Because the students learn at their own pace during the asynchronous sessions, they attend the synchronous sessions better prepared. As a result, these sessions can focus on more active forms of learning that effectively engage students, promote higher-order thinking, clarify difficult concepts, and provide more personalized support.
Course format
The course consists of:
• An asynchronous self-paced online learning phase, comprising the following resources:
o The book titled “Modelling of nuclear reactor multi-physics − From local balance equations to macroscopic models in neutronics and thermal-hydraulics”, by C. Demazière, ISBN-978-0-12-815069-6, Academic Press/Elsevier (2020) https://www.elsevier.com/books/isbn/9780128150696 The course participants will get their private copy of the book.
o Pre-recorded lectures or webcasts are available to students for on-demand viewing.
o Online quizzes that focus on conceptual understanding.
• Synchronous hybrid interactive sessions (online or onsite), comprising the following resources:
o Wrap-up sessions designed to summarize the key concepts presented in the book/webcasts and to address student needs.
o Discussions based on interactive quizzes.
o Programming sessions, during which the attendees will have to solve, under the teacher’s supervision and guidance, some programming assignments in Matlab Grader.
For the off-site attendees, the interactive sessions are live broadcasted on the web. They will also be recorded and made available on the web. For the remote attendees, it is nevertheless strongly recommended to attend the interactive sessions when they take place to fully benefit from the teacher’s support.
The preparatory (i.e., asynchronous) work represents ca. 100 hours of self-studies. The synchronous interactive sessions represent ca. 60 hours.
Course certificate and course credits
A course certificate will be issued to the students who obtain at least 50 points (out of 100 max points). The total number of points is estimated as follows:
• The points on the asynchronous quizzes will account for 25% of the total number of points.
• The active participation to the synchronous sessions will account for 75% of the total number of points.
The certificate will briefly describe the course contents, the number of hours the different course elements represent and the number of equivalent ECTS credits (European Credit Transfer and Accumulation System). The course is worth 6 ECTS.
Technical course contents
The curriculum for the course follows the chapters in the book “Modelling of Nuclear Reactor Multi-physics – From Local Balance Equations to Macroscopic Models in Neutronics and Thermal-Hydraulics” (ISBN 978-0-12-815069-6) and is thus organized in seven chapters.
Chapter 1 – Introduction
In the introductory chapter, the main topics addressed in the book are first discussed, together with the objectives the course attempts to tackle. Areas not covered in the course are also described. The structure of the course is thereafter presented. Both the technical contents as well as the followed pedagogical approach are dealt with. The notations and conventions used throughout the course are then highlighted. Finally, some mathematical concepts and theorems of importance for the following chapters are presented.
Chapter 2 – Transport phenomena in nuclear reactors
In this chapter, the governing equations for neutron transport, fluid transport, and heat transfer are derived, so that students not familiar with any of these fields can comprehend the course without difficulty. The peculiarities of nuclear reactor systems, i.e., their multi-physic and multi-scale aspects, are dealt with. An overview of the modelling strategies is thereafter given, with particular emphasis on deterministic methods, which represents the focus area of the course.
Chapter 3 – Neutron transport calculations at the cell and assembly levels
In this chapter, the computational methods for neutron transport at both the pin cell and fuel assembly levels are presented. The chapter is aimed at following the solution procedure in fuel pin/lattice codes as much as possible. This includes resonance calculations of the cross-sections, the determination of the micro-region micro-fluxes, and of the macro-region macro-fluxes, and finally spectrum correction. The chapter ends with the preparation of the macroscopic cross-sections for sub-sequent core calculations, where the effect of burnup is also detailed.
Chapter 4 – Neutron transport calculations at the core level
In this chapter, the computational methods in use for core calculations are presented. In the first part of this chapter, the treatment of the angular dependence of the neutron flux is described. In the second part, the treatment of the spatial dependence of the neutron flux is outlined. Thereafter, the solution procedure for estimating the core-wise position- (and possibly direction-) dependent multigroup neutron flux is described. Finally, the methodology used for determining the core-wise space- and time-dependent neutron flux in case of transient calculations is derived.
Chapter 5 – One-/two-phase flow transport and heat transfer
This chapter focuses on the computational methods used for one-/two-phase flow transport and heat transfer. From the local governing equations of fluid flow and heat transfer, macroscopic governing equations are derived, and the underlying assumptions clearly emphasized. The different flow models commonly used in nuclear engineering are introduced, models having various levels of sophistication: the two-fluid model, the mixture models with thermal equilibrium and specified drift, and the Homogeneous Equilibrium Model. The temporal and spatial discretization of the flow and heat transfer models are given special attention, with emphasis on their stability, consistence, and convergence.
Chapter 6 – Neutronic/thermal-hydraulic coupling
This chapter tackles solving the coupling between neutronics and thermal-hydraulics at the core level. Various aspects of multi-physics coupling are highlighted: segregated versus monolithic approaches, coupling terms and non-linearities, information transfer, preparation of the macroscopic material data (cross-sections, diffusion coefficients, and discontinuity factors) as functions of the thermal-hydraulic variables, spatial coupling. The numerical techniques that can be used to solve multi-physics temporal coupling either in a segregated or in a monolithic manner are also discussed in detail.
Chapter 7 – Conclusions
The last chapter summarizes in, a nutshell, the macroscopic modelling techniques and presents a quick overview of the current efforts in high-fidelity reactor modelling.
