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, making it compatible with full-time work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is VISIPLAN, RESRAD, MicroShield, Primavera P6 and Autodesk Revit, in free, academic or evaluation versions. Tests are studied using real procedures for pre-decommissioning radiological characterisation, decontamination and cutting planning, and material clearance files. Assessment is continuous for each module, plus the final Master's Thesis.
Standards covered: IAEA GSR Part 6 Decommissioning of Facilities, Directive 2013/59/Euratom, Royal Decree 1029/2022 (Regulation on health protection against the risks of exposure to ionising radiation), IAEA GSR Part 3 Radiation Protection and Safety of Radiation Sources, NUREG-1575 MARSSIM, Directive 2011/70/Euratom and Royal Decree 102/2014.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
