Nuclear Probabilistic Safety Assessment (PSA)



This course enables students to understand and apply Probabilistic Safety Assessment (PSA) techniques with particular relevance to the nuclear industry. It provides an overview of nuclear industry safety assessment guidelines and principles. Reliability theory and system modelling are covered, including event tree and fault tree analysis. Consequence modelling in the nuclear industry and typical hazard scenarios such as fire, aircraft crash, natural hazards, etc. is also discussed. The course includes application of PSA results and demonstration of ALARP.


Who is this for?

Managers, engineers and HSE professionals who need to lead or undertake risk management processes for their organisation and facilities, and individuals new to the nuclear industry who require an overview of the industry’s risks.

Outline content

  • Introduction to safety assessment in the nuclear industry
  • Safety assessment, guidelines and principles
  • Reliability theory and concepts
  • System reliability and modelling
  • Fault and hazard identification
  • Frequency analysis
  • Supporting data
  • Consequence analysis in the nuclear industry
  • Hazards PSA
  • Application of results, including ALARP demonstration

At the end of the course you should be able to:

  1. Deduce the PSA techniques appropriate to a real-life nuclear plant
  2. Evaluate the risks associated with the operation and design of the plant
  3. Identify and critically examine any additional measures that may be required to ensure that the risks are both tolerable and ALARP
