Level 1 PSA - Internal Events
The purpose of this course is to give participants both a broad overview and a detailed introduction to PSA and its various elements. The focus is on Level 1 PSA and internal events analysis.
The course is designed for individuals with little or no experience in PSA. The lectures combine simple theory with interesting practical examples from industry (BWRs and PWRs). These are followed by hands- on practice using RiskSpectrum® PSA software.
An overview of the most widely used international references (IAEA, USNRC, CSNI etc.) will be provided for each stage of the internal events analyses.
