Senior Core Physics and Radiation Protection Engineer

Your mission
Are you passionate about core physics, radiationprotectionand criticality?

Are you motivated to apply yourexpertiseandknow-howto the ongoing design studies for the Thorizon One reactor?

Are you passionate about designing cutting-edgeneutronicssystems and solving complex engineering challenges?

Do you get energized when working on innovative solutions?

You will be a major contributorofthecore physics, radiation protection, and criticalityexpertisecenter, whose primary missions are, on the one hand, to provide comprehensive support and expertise in this area to the system design teams incharge of thefuel cycle, thereactordesign and safety studies and, on the other hand, to define, execute, and adapt where needed the validation programusingexperiments carried out through shared initiatives, designed to ultimately prove that the innovations in our solution are feasible within the performance, cost, and time constraints of our project.

Within this general framework you will develop methods and tools to perform core physics, radiationprotectionand criticality studies,possibly in collaboration with external specialists, perform high quality studies with the appropriate computational tools, andvalidatethe computational tools. In your role, you can carry out an analysis to meet anycore physics, radiationprotectionand criticality needs for Thorizon projects (Pioneer nuclear demonstrator design, FOAK/NOAK design), including budget, planning, tools selection, calculations, report issuance. You interact easily with other areas of expertise (such as nuclear safety,thermal-hydraulics,chemistry and mechanics).

Your level ofexpertiseallows you to prioritize based on the importance of the needs, and as an expert, you have the power to recommend any necessary actions for the project related to your area of expertise. Furthermore, youparticipatein external networks, including international initiatives, to stay at the forefront of industry developments. In this environment, you get the unique opportunity toput your knowledge to the best use,develop your ideas,and explore various aspects of thermal-hydraulics engineering.

This role is based in Amsterdam, Netherlands or in Lyon, France.

In this role you will:
Set up an effective core physics computational train, using both probabilistic(MCNP, SERPENT for example) and deterministic approaches(APOLLO3, SCALE for example), as well asprovidingnumerical/physical insights and practical approachestoestablishappropriatecouplingwiththermal-hydraulics for effective transient analyses.
Set up core radiation protection or criticality models for simulation of shutdown, storage,handling and transport
Set up andmaintainscientific computing environments on Linux, including installing and configuring scientific software, libraries, and data analysis tools.
Automate the studies and their pre- and post-processing.
Contribute to definition and justification of the safety case.
Contribute to orestablisheffectiveexchangewith other codes and results from other disciplines, such as thermal-hydraulics, salt compositionchemistryand structural mechanics.
Participate in specifying, selecting, and managing external contractors and suppliers that support the project.
Guide junior colleagues in the same discipline, andshare your knowledge with your teammates.
Create transparency on development progress,identify issues and challenges,and propose solutions that will help team problem-solving and design iteration.
Implement a learning loop and ensure lessons learned are systematically integrated in way of working and the design itself.
Contribute to the definition, execution, and adaptation where neededofthe validation programusingexperiments, designed to ultimately provethat the innovations in our solution arefeasiblewithin the performance, cost, and time constraints of our project. This program includes thequalificationof thecore physics, radiationprotectionand criticality

Computational Tools to be used for design and safety, applying national (e.g., ASNR guide 28) or international (IAEA in particular) approaches.
Participate in meetings with regulators with the aim of defending in-house positions and contribute tomaintainingan active dialogue with regulators (in particular ASNR, ANVS and FANC).
Be involved in various international initiatives (IAEA, Euratom…) dedicated toyourdiscipline.
Stay updated on industry trends and advancements in approaches, methodologies,Computational Tools incore physics, radiationprotectionand criticality.
Report tothe Core Physics lead, andworkin different project teams.
