How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetable: students progress at their own pace within the intake, which makes it possible to combine study with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is FRAPCON/FRAPTRAN, TRANSURANUS, BISON (MOOSE), MATLAB, Python (SciPy), in free, academic or evaluation versions. Tests are studied using real post-irradiation examination hot cell procedures, rod profilometry and gamma scanning, and electron microscopy of irradiated fuel. Assessment is continuous, module by module, plus the final integrative project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Explain the physical mechanisms that cause swelling in irradiated fuel.
Analyse the generation, diffusion and release of fission gases in UO2.
Describe the formation and effects of the high burnup structure (HBS).
Interpret post-irradiation examination results such as profilometry and metallography.
Model swelling and pellet-cladding interaction with fuel performance codes.

Frequently asked questions
The programme is 300 hours in total, spread over 3 to 5 months. That is an average of 10 to 15 hours per week, compatible with a full-time job.
You will work with FRAPCON/FRAPTRAN, TRANSURANUS, BISON (MOOSE), MATLAB and Python (SciPy). Free, academic or evaluation versions are used, and the tutor indicates the free alternative where one exists.
An own diploma from SEIUM upon passing the continuous assessment and the integrative project. It is in-house training, not an official qualification from the Ministry.
Yes. Modules passed in a course or postgraduate diploma in the same area are credited towards the advanced programme. Check the recognition policy when you enrol.
