Educational objectives Modern engineering systems and industrial plants requires a systems
approach and the use of formal methodologies for assessing reliability
and risk analysis. Thus, the course aims to provide the appropriate
methodologies and generic computational tools to deal with technical and
scientific rigor. The expertise provided are those required for the
formation of the experts of reliability systems and industrial safety,
in the most broad sense, including the engineering design and
reliability of the mitigation and protection systems, protection of
health and environmental aspects.
During the course simple exercises are planned to support the
understanding of the material developed in class. The exercises are
presented in detail the main types of engineering systems and industrial
systems that require an analysis of associated risk, highlighting the
different levels of detail required. During the course, the development
of numerical examples of the theoretical and formal cases are presented
in class. Finally, are schematically presented case studies of risk
analysis in real plants belonging to these categories. It is provided
only a final oral examination.

Educational objectives xpected Learning Outcomes (Dublin Descriptors)
1. Knowledge and Understanding
Regulatory framework: Thoroughly understand the regulatory approach to
nuclear safety and the evolution of its design and mitigation requirements.
Advanced reactors: Acquire a solid knowledge of all the main types of
innovative and advanced nuclear reactors, grasping the specific features of Gen
III+ (active and passive), SMRs, and Gen IV systems (SFRs, LFRs), including an
overview of fusion applications. Know the operating diagrams of the auxiliary and
safety systems used in innovative and advanced nuclear reactors.
2. Applying Knowledge and Understanding
Prediction of plant behavior: Be able to predict the thermal-hydraulic and
systemic behavior of a nuclear power plant during an accident sequence,
mastering all levels of safety analysis (specifically DBA, DEC-A, and DEC-B).
Transient safety analysis setup: Develop the ability to set up a transient
analysis (using computational codes such as RELAP5) to verify safety
requirements. The application focuses on main safety and auxiliary systems,
strictly taking into account the specific criteria and aspects of nuclear regulations.
3. Making Judgements
Safety margin assessment: Critically interpret the data extracted from transient
thermal-hydraulic simulations to evaluate compliance with operational limits and
the effectiveness of the adopted safety architectures against regulatory criteria.
4. Communication Skills
Technical reporting and discussion: Be able to write and critically discuss an
engineering report on the performed safety analysis (project work), using the
correct technical and regulatory terminology.
Professional interaction: Demonstrate the ability to engage competently with
current industrial and research entities in the advanced nuclear sector (e.g.,
through exposure to seminars by Ansaldo, newcleo, and ENEA).
5. Learning Skills
Continuous updating: Develop the autonomy needed to stay updated on the
evolution of international regulations (e.g., IAEA guidelines) and to understand the
development trajectories of new analysis and simulation tools for advanced
systems.
