How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so the programme can be combined with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is MOOSE, Serpent, Code_Aster, SALOME and FRAPCON, in free, academic or evaluation versions. Practical work is based on real procedures for coupled transient simulation, thermomechanical analysis of fuel rods and uncertainty propagation in multiphysics calculations. Assessment is continuous by module, plus the final Master's Thesis.
Standards covered: ASME BPVC Section III, ASME NQA-1, IAEA SSG-2, IAEA SSG-52, 10 CFR 50.46, ASME V&V 20, NUREG-0800 (Standard Review Plan).
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
