How you'll learn
A 100% online programme 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 the intake, so it fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is OpenMC, Serpent, MCNP, CASMO/SIMULATE and MOOSE, in free, academic or evaluation versions. The practical work is based on real procedures for cell and core calculations, coupled multiphysics simulation and uncertainty analysis with benchmarks. Assessment is continuous by module, plus the final project.
Standards covered: NUREG-0800 Section 4.3, NUREG-0800 Section 4.4, Regulatory Guide 1.203, ASME NQA-1, IAEA SSG-52, ANSI/ANS-19.6.1.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
