Obiettivi dell'insegnamento

Nuclear and energy equipment and systems require a systematic approach to design and operation, with specified safety and reliability constraints/objectives (safety-based and reliability-based design and operation).

The goal of this course is to provide the students with the adequate competences on methods and computational tools for the evaluation, the analysis and the control of the risk associated to the operation of nuclear and energy equipment and systems. These competences, typical of safety and reliability analysts and managers, are necessary in all modern engineering for the design and operation of safe and reliable systems.

The course is listed among those contributing to the certification of "Ambassador in Green Technologies".

The course is offered in:

a 10-CFU version for nuclear engineering students named “RELIABILITY, SAFETY AND RISK ANALYSIS A+B”. The expected learning outcome and the topics of this version of the course are the union of those of Parts I, II and III in the following sections.

in a 8-CFU version for energy engineering students named “RELIABILITY, SAFETY AND RISK ANALYSIS C”. The expected learning outcome and the topics of this version of the course are the union of those of Parts I and II in the following sections.

in a 5-CFU version named “RELIABILITY, SAFETY AND RISK ANALYSIS B”. The expected learning outcome and the topics of this version of the course are the union of those of parts I and III

in a 5-CFU version named “RELIABILITY, SAFETY AND RISK ANALYSIS A”. The expected learning outcome and the topics of this version of the course are the union of those of parts II and III

Argomenti trattati

PART I

Basics of probability theory for applications to reliability analysis and risk assessment (ELO I.1);

Estimation of reliability parameters from field data (ELO I.3);

Reliability of simple systems: series, parallel, redundancies, standby (ELO I.3);

Reliability and availability of complex systems subject to realistic procedures of inspection, maintenance, repair, renewal (ELO I.3);

Monte Carlo simulation methods for reliability and availability analysis: stochastic simulation framework; random sampling; estimation of reliability and availability of complex systems (ELO I.4);

Maintenance engineering for nuclear installations and energy systems (ELOs I.2 and I.5).

PART II

Risk: qualitative and quantitative definitions (ELO II.1);

Case studies taken from the oil & gas, power production and nuclear industries will be illustrated, and quantitative exercise classes will be carried out in support to the comprehension of the material covered in class.

Prerequisiti

No pre-requisites are required.

Modalità di valutazione

Student attending the 8 and 10-CFU versions (RELIABILITY, SAFETY AND RISK ANALYSIS A+B)

The evaluation considers: a) hands-on exercises continuously assigned during the course, b) the development of a project, c) a scientific talk to be given in front of the class, d) a written exam.

a) Hands-on exercises will contribute to 10% of the final grade. They will verify ELOs I.1, I.3 and II.2, II.3.

b) The project consists in the development of a stochastic simulation code for the estimation of the reliability and availability of complex systems or for condition-based maintenance of nuclear and energy equipment and systems (ELOs I.4 and I.5). This part of the exam will contribute to 10% of the final grade.

c) the scientific talk will be on an advanced topic on risk and reliability assessment, which will be assigned by the instructor. It will evaluate the student ability of communicate knowledge clearly and unambiguously. This part of the exam will contribute to 10% of the final grade.

Parts a), b) and c) will be developed by the students in multidisciplinary team formed by a nuclear and an energy engineering student.

d) The written exam will contribute to 70% of the final grade and will evaluate the student abilities in:

- applying the techniques for quantifying the reliability and availability and controlling the risk of nuclear and energy equipment and systems (ELOs I.3 and II.2)

- understanding the risk concept, the probabilistic framework for its assessment, the basics of probability theory and stochastic methods for reliability, availability and risk analysis, environmental risk assessment, dependent failures, importance measures, the maintenance engineering approaches. (ELOs I.1, I.2, II.1, II.3 and III.1)

- making judgments on the confidence in the results obtained, for robust decision-making (ELO II.3).

The written exam of the students attending the 10 CFU version of the course will also verify their understanding of prognostics and health management methods for condition-based and predictive maintenance of nuclear equipment and systems and the advanced topics discussed in the seminars.

Students attending the 5 CFU versions of the course will be verified on the corresponding ELOs. The exam of students attending RELIABILITY, SAFETY AND RISK ANALYSIS B consists in parts a), b), c) and d) limited to the ELOs in I and II. The exam of those students attending RELIABILITY, SAFETY AND RISK ANALYSIS A consists in parts a) (10%), c) (10%) and d) (80%) limited to the ELOs in II.
