General Information

Learning outcomes

The student who successfully completes the course will be able to demonstrate a solid knowledge of main items in nuclear safety field (methodologies, risk and accident analysis, etc…) and will have the ability to run some of the calculation codes mostly used for the safety assessment of nuclear power plants. In addition he should have acquired a way of thinking apt for performing nuclear safety analyses and also some fundamental instruments to be used for evaluating the general correctness of the code calculation results.

Course contents

Main items treated are:
• the nuclear safety methodology and related procedure of licensing in USA
• the objectives and the fundamental safety principles of IAEA (INSAG 3 and 12)
• the nuclear safety methodologies based on reliability
* main aspects of Italian legislation on nuclear safety, nuclear emergency planning
• the Rasmussen report (WASH 1400)
• the accidents in LWR and design principles of the main safety and protection systems
• the severe accidents: phenomenology and methods of analysis
• the containment systems of nuclear power plants and related operation principles; the main engineering safeguard systems associated to the containment
• source term for accidents in LWR
* peculiar aspects of accidents in CANDU NPP and in Liquid Metal FBR
* the criticality accidents
• the INES scale for nuclear accidents classification
* safety culture
* the costs-risks-benefits analysis and nvironmental impact of the energy cicles
* the TMI2, Chernobyl and Fukushima accidents.
