Your mission
The main objective of the internship is to identify, analyze, and critically assess existing reactor physics experimental integral data relevant to the project’s scope (e.g. k-eff, reaction rates, ...). The results will contribute to a better understanding of current data limitations and uncertainties, and help guide modelling, simulation, and experimental efforts within the project.
In this role you will:
Main Tasks
- Perform a comprehensive literature review of experimental integral data from journals, technical reports, and databases (e.g. IRPHE, ...).
- Identify key experiments, measurement techniques, and associated uncertainties.
- Compare experimental results with calculated results and give an interpretation of the comparison where relevant.
- Assess the consistency, reliability, and applicability of available data for the targeted innovative application.
- Summarize findings in clear technical reports and presentations.
- Propose recommendations for data selection, further analysis, or future experimental needs.
By the end of the internship, the candidate will have:
- Developed a structured and critical overview of experimental integral data relevant to an advanced nuclear project.
- Gained hands-on experience with experimental databases and neutronics calculations.
- Contributed directly to an innovative research and development effort.
- Built strong foundations for further work in integral data evaluation, reactor modelling, and experimental techniques.
About you:
- Master’s-level student (or final-year undergraduate) in nuclear engineering, physics, ora relatedfield.
- You are passionate about neutronics andwilling to merge existing knowledge into the Thorizon reactors.
- Strong analytical skills and ability to synthesize complex technical information.
- Familiarity with neutronics key concepts,data bases and automation skills (Python) is highly desirable.
- Excellent communicator (clear is kind) in English both spoken and written. French or Dutch is a plus.
- Strong organizational and multitasking abilities, with attention to detail and accuracy.
- You like working in an agile manner and are comfortable at the fast-moving pace of a technological scale-up.
What you can expect from us:
- The opportunity to help realize the most promising reactor technology and advance Europe's energy future.
- Being part of an exceptional team that combines engineering rigor, scientific excellence, and entrepreneurial drive.
- Working in multidisciplinary teams on ambitious missions, with responsibility and meaningful impact from day one.
- A fast-moving deep-tech environment where initiative is valued and people are trusted to make decisions.
- Complex, multidisciplinary challenges that will stretch you and accelerate your growth.
- Competitive compensation and participation in our employee profit-sharing plan.
- An international workplace with offices in the heart of Amsterdam and Lyon.
- The expected salary conditionsare of 600 €/month.
- The expected duration of the internshipis of 5-6months starting as of 1st of September 2026 (start date can also be changed depending on the needs of the candidate).
