The purpose of this two week workshop is to provide regulatory body staff, future operators and technical support organizations (TSOs) in developing countries, working in the area of deterministic safety assessment and performing reactor safety reviews, with an overview of deterministic safety assessment methods and tools including those related to the design extension conditions as well as an overview of the engineering aspects important to safety. This workshop includes material from the IAEA’s Safety Assessment Education and Training (SAET) Programme aimed at familiarizing participants with the main concepts and methods of safety assessment in the IAEA safety standards, and will be of particular interest to participants from countries introducing nuclear power programmes.


Week 1: Deterministic Safety Assessment
• Safety assessment purpose and scope
• Introduction to: relevant IAEA safety standards; thermal-hydraulics; reactor physics; and design basis analysis (DBA)
• DBA postulated initiating events (PIEs)
• DBA acceptance criteria
• Design extension conditions (DEC)
• Conservative versus best estimate approaches
• Format and content of the safety analysis report

Week 2: Engineering Aspects Important to Safety
• Design safety requirements
• Introduction to assessment of engineering aspects
• Systems, structures, components and safety classification
• Equipment qualification
• Site characteristics and evaluation
• Assessment of external hazards
• Assessment of internal hazards
• Assessment of major systems: reactor core; coolant; containment; I&C; and electrical
• Assessment of auxiliary and supporting systems
• Human factors
• Aging, life limiting factors
• Assessment of safety over the lifetime of the plant & periodic safety review.
