Introduction to Nuclear Fission Reactors Course — studying from Ireland
Ireland has no nuclear power generation, and its nuclear engagement is centred on radiation protection, research, medical applications and international policy. The Radiological Protection Institute of Ireland, now part of the Environmental Protection Agency, regulates radiation sources and monitors radiation exposure. Engineers and scientists in this area typically work in research, healthcare, environmental monitoring, decommissioning oversight and nuclear safeguards. Professional standards and expertise are coordinated through national and international bodies, with Ireland participating in European and international nuclear safety frameworks.
Fees for Ireland: €644 (Euro), with instalments and employer sponsorship available.

Questions from Ireland
Is Ireland a country with a nuclear power industry, and how is nuclear engineering professionally recognised here?
Ireland has no operating nuclear power plants, so nuclear engineering careers here are mainly in regulation, research, decommissioning oversight and international projects. The Radiological Protection Institute of Ireland is the national regulator for radiation protection. SEIUM's qualifications are private and not accredited by this or any national body, so recognition depends on employers or the relevant body.
How might employers in Ireland view this training for nuclear-related roles?
Given Ireland's limited domestic nuclear industry, relevant roles are often with regulators, research institutions or multinational employers. Those employers decide how much weight to give a private online qualification and will usually look for specific radiation protection or regulatory credentials. There is no guarantee of any role or outcome.
What should I consider about workload and language before enrolling?
The programme is fully online and taught in English, so you can study from Ireland at your own pace. Study durations are 300, 800 or 1,900 hours depending on the course, so plan your time carefully. Fees can be paid in instalments, employer sponsorship is possible, and an assigned technical tutor supports your progress.

How you'll learn
Fully 100% online training on the SEIUM campus, with downloadable material, recorded lectures and a dedicated technical tutor. No fixed timetable: students progress at their own pace within the intake, making it possible to combine study with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is IAEA Reactor Simulators for PC, Serpent 2, MATLAB, Python (NumPy), in free, academic or evaluation versions. Tests are studied using real power plant simulator procedures for educational purposes, neutron balance calculations and analysis of operating cases. Assessment is continuous per 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 fundamentals of nuclear physics as applied to fission.
Classify the main types of fission reactors.
Describe the core and its neutronic and thermal behaviour.
Identify the main and auxiliary systems of a power plant.
Understand the principles of safety, operation and regulation.
