Senior nuclear system thermal-hydraulics analyst
Pubblicato il 21-08-2026 - Experteer Italy in Italia
Overview Experteer Overview In this role you will lead thermal-hydraulic studies to support design and safety assessments for LFR projects across France, Slovakia, and the US. You will join the Plant Thermal Hydraulics Unit within the Engineering Department, collaborating with cross-functional teams to deliver technical analyses, deliverables, and schedules. You will coordinate studies, mentor junior engineers, and contribute to V&V; activities and tool development. You will leverage 1 D system codes (and CFD as applicable) to model steady-state and transient behavior of nuclear cooling circuits, including interactions with heat exchangers in the lead pool. This position offers the opportunity to shape safety assessments. Benefits Conceptualize, model, and analyze thermal-hydraulic systems for nuclear reactors, focusing on steady-state and transient scenarios Coordinate technical studies and oversee externalized activities, ensuring timely, accurate deliverables and cost/schedule reporting Support design activities of components,
especially heat exchangers in contact with the lead pool Perform V&V; activities for thermal-hydraulic codes and identify validation gaps and R&D; needs Lead and mentor junior team members, define activity scopes, and select appropriate tools and methods Draft and review project deliverables (calculation notes, design specs, technical reports) Collaborate with cross-functional teams to refine design requirements and provide technical feedback Responsibilities MSc in Nuclear Engineering (or Master/Ph D is a plus) Robust experience in thermal-hydraulics for single-phase and two-phase flows and heat transfer in nuclear applications Strong knowledge of nuclear reactor safety principles Proven experience with at least one 1 D system thermal-hydraulic code (RELAP5, CATHARE, ATHLET) CFD expertise is a plus Experience with liquid metal reactors is a strong plus Strong analytical skills and ability to present technical findings Proficiency in programmi
