Content (Syllabus outline)

Nuclear safety principles:

-Levels (measures) of nuclear safety, defence-in-depth.
-Definitions and principles of safety, risk, reliability and availability of systems, structures and devices. - Safety systems and their characteristics: redundancy, independence, separation, variety, fail-safe principle and single failure
- Safety analyses. Analyses of transients and accidents. - Basic probability theory and Boolean algebra.
-Databases and probabilistic models. Methods for evaluation of safety and reliability - Theory and Practice: fault tree, event tree, analysis of failure modes and effects.
- Common cause failure - methods and examples. - Safety culture - the organization and management. - Measures of reliability and safety of systems and facilities. Risk criteria. - Risk based decision making. - Periodic safety review. - Quality assurance: program, procedures, implementation.

Objectives and competences

Objectives: To know the basics about the security and reliability.
To acquire knowledge about the importance of system reliability for the safe operation of nuclear facilities.
To develop a sense for responsibility of the safe use of energy and to promote a safety culture.

Intended learning outcomes

Knowledge and understanding:
Ability to understand the laws and regulations related to nuclear safety. Ability to apply standard methods, procedures and processes. Commitment to professional ethics.
Application:
Using standard methods, procedures and processes in practice.

Reflection:
Own understanding of the theory and experience in practice, critical evaluation of the theoretical principles and practical behavior.
Transferable skills:
To acquire skills for using domestic and foreign literature and other sources, collecting and interpreting data, identification and problem solving, critical analysis, synthesis, writing articles, teamwork.

Learning and teaching methods

Lectures, where students learn about the theory, research seminars, project work, individual work, guided individual study. Some content will be given in the form of e-lessons, using web-based content for distance learning and the use of the current scientific research projects.

Assessment

2 midterm exams or final written exam
oral exam
grading: 5 (fail), 6-10 (pass) (according to the Statute of UL)
