Course in Nuclear Reactor Thermal-Hydraulics
Online 300-hour course in nuclear reactor thermal-hydraulics. 6 modules covering IAEA SSG-2 Rev. 1 (deterministic safety analysis), 10 CFR 50.46 (ECCS acceptance criteria) and RELAP5-3D. Personal tutor assigned and enrolment open.
Course in Nuclear Reactor Thermal-Hydraulics — studying from Australia
Australia does not operate nuclear power plants, but nuclear science and technology play important roles in research, medicine, mining and regulation. The Australian Nuclear Science and Technology Organisation operates research reactors and produces radiopharmaceuticals, while uranium mining is conducted in South Australia, the Northern Territory and Queensland. Nuclear engineering skills support regulatory oversight, radiation safety and decommissioning activities. Employers include ANSTO, the Australian Radiation Protection and Nuclear Safety Agency, mining companies and specialist consultancies.
Fees for Australia: A$868 (AUD), with instalments and employer sponsorship available.

Questions from Australia
Does this programme meet Australian nuclear licensing or regulatory requirements?
No. SEIUM qualifications are private and are not accredited by any national body. Nuclear activities in Australia are regulated by the Australian Radiation Protection and Nuclear Safety Agency and related authorities, which set their own competency requirements. Check directly with the regulator and your employer about any qualifications needed for a specific role.
Which Australian organisations might consider this training for nuclear-related roles?
Australian employers in this area include research organisations, radiation protection services, mining and resources companies, and consultancies working on nuclear-related projects. Hiring depends on each organisation's requirements and on security and licensing needs. A private qualification is unlikely to be sufficient alone, so combine it with relevant experience.
Is the programme workable alongside a job, and how is it funded?
The programmes are delivered entirely online in English with an assigned technical tutor, allowing study from Australia around work commitments. Fees can be paid in instalments, and employer sponsorship is possible. Review the programme length, from 300 to 1,900 hours, and plan carefully.

How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: students progress at their own pace within the intake, which makes it possible to combine the course with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is RELAP5-3D, TRACE, CTF (COBRA-TF), ANSYS CFX, OpenFOAM, in free, academic or evaluation versions. Tests are studied using real procedures for subchannel analysis, LOCA and transient simulation, and calculation of margins to DNB. Assessment is continuous 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.
Apply mass, energy and momentum balances to the core.
Analyse two-phase flow, boiling and boiling crisis.
Carry out subchannel analysis of the core.
Model reactor systems with system codes.
Simulate transients and loss-of-coolant accidents.

Frequently asked questions
The programme totals 300 hours, spread over 3 to 5 months. That is an average of 10 to 15 hours per week, compatible with a full-time job.
You work with RELAP5-3D, TRACE, CTF (COBRA-TF), ANSYS CFX and OpenFOAM. Free, academic or evaluation versions are used, and the tutor indicates the open-source 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 Ministry qualification.
Yes. Modules passed in a course or postgraduate diploma in the same area are credited towards the advanced programme. Check the credit transfer policy when you enrol.
