Probabilistic Safety Assessment (PSA) Level 1 Course
Online 300-hour course in Probabilistic Safety Assessment (PSA) Level 1. 6 modules covering IAEA SSG-3 (Rev.1) (Level 1 PSA), ASME/ANS RA-Sa-2009 (PSA standard) and RiskSpectrum PSA. Assigned tutor and open enrolment.
Probabilistic Safety Assessment (PSA) Level 1 Course — studying from Singapore
Singapore has no nuclear power plants, and nuclear activity is limited to research, radiation safety and the use of radioisotopes in industry and healthcare. The National Environment Agency regulates radiation protection and the use of radioactive materials. Engineers with nuclear skills in Singapore typically work on radiation safety, nuclear instrumentation or regional advisory and monitoring roles, rather than on fuel cycle operations. Demand is linked to medical, research and industrial applications.
Fees for Singapore: S$780 (Singapore dollar), with instalments and employer sponsorship available.

Questions from Singapore
Will this qualification be recognised by professional bodies in Singapore?
SEIUM's qualifications are private, not official state degrees, and are not accredited by any national body in Singapore. Singapore has no operating nuclear power plants, and nuclear-related activities are overseen by the National Environment Agency and other agencies. Professional Engineer status is handled by the Professional Engineers Board. Recognition of a private qualification is decided by employers or the relevant body.
How might this training be used by employers in Singapore?
Singapore has no domestic nuclear power industry, so opportunities in this field are limited and mostly linked to regional energy projects, research, radiation safety, or international employers. An online private qualification may support general knowledge but does not guarantee a role. Employers will weigh relevant experience and licensing highly.
Can I study this alongside a full-time job, and can my employer help fund it?
The programme is online and taught in English, so you can study from Singapore while working, with no student visa needed. The workload is substantial, so be realistic about hours. Fees can be paid in instalments, and employer sponsorship is possible, though you should confirm whether your employer funds training in this specialised area.

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 enrolment period, making 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 RiskSpectrum PSA, SAPHIRE, CAFTA, Python (uncertainty analysis), in free, academic or evaluation versions. Case studies are based on real procedures for constructing event and fault trees, quantifying core damage frequency, and analysing importance and sensitivity. Assessment is continuous per 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.
