Course in Sodium-Cooled Fast Reactors — studying from the United Kingdom
The United Kingdom has a long history in nuclear engineering and maintains a substantial sector spanning reactor operation, decommissioning, fuel cycle and new build projects. Sites at Sellafield, Hinkley Point, Dounreay and Harwell host work on fuel cycle, waste management and advanced reactor technology. Organisations such as the Nuclear Decommissioning Authority, EDF, Rolls-Royce SMR and Urenco UK employ engineers in design, safety and operations. Nuclear activities are overseen by the Office for Nuclear Regulation, which sets strict safety and security requirements.
Fees for the United Kingdom: £373 (Pound sterling), with instalments and employer sponsorship available.

Questions from the United Kingdom
Which UK regulators and bodies govern nuclear engineering, and how do they treat private training?
The Office for Nuclear Regulation regulates nuclear safety in the UK, and the Nuclear Institute is the main professional body. Competence requirements for licensed sites are set by the operator and regulator. SEIUM's qualifications are private, not state degrees, and not accredited by any national body, so they carry no regulatory standing and recognition is at the discretion of employers and the Nuclear Institute.
Do UK nuclear operators and fuel cycle employers hire people with private online qualifications?
UK nuclear employers typically require security clearance, specific competence assessments and qualifications recognised within the industry. A private online qualification may add to your profile but is unlikely to replace formal requirements. Employers decide its value, so check the entry criteria for roles you want before investing in the programme.
How intensive is the programme, and can I fund it through employer sponsorship in the UK?
Specialist courses take 300 hours, postgraduate diplomas 800 hours and master's programmes 1,900 hours, all online in English with an assigned technical tutor. Fees can be paid in instalments. Employer sponsorship is possible, and many UK nuclear employers run their own training schemes, so ask whether your employer would fund this specifically.

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 programme with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is SAS4A/SASSYS-1, Serpent, ERANOS, OpenFOAM, in free, academic or evaluation versions. Case studies are based on real procedures for analysing reactivity coefficients in fast spectrum, studies of unprotected transients and reviews of operating experience of sodium reactors. Assessment is continuous by module plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
