This text has been prepared to support the Nuclear Power Plant Systems and Operation course, which has the following main components:
• modules in science fundamentals, equipment and systems principles relevant to CANDU reactors;
• modules in CANDU reactor power plant systems and their operation;
• self-study of this text to support the above modules;
• problem solving assignments to reinforce the understanding and application of the course material;
• operation of a CANDU-9 power plant simulator;
• reviews in a workshop or tutorial format to answer questions and exchange information on topics that are of interest to the majority of the course participants.

The traditional approach to teaching nuclear power plant design and operation has been to begin with the scientific theory and mathematical representation of the fundamental processes that take place in a nuclear power plant, studying simplified models, individual pieces of equipment, eventually combining these into systems and finally synthesizing a complete generating unit. This approach may be called ‘bottom-up’, since each building block must be understood before subsystems can be formed into systems and eventually into a working whole. Although this approach has been used successfully for many generations of students, it is not considered appropriate for a class of adult learners with varied experience in the nuclear power field. Such individuals will typically be experts in one or more areas relevant to nuclear power plants, but few if any will have a good understanding and experience with the overall operation of specific power plant types.

The approach followed in this text and in the course it supports is called ‘top-down’. It is built on the assumptions that the participants want to achieve an overall understanding of how a nuclear power plant operates, that each of them are already familiar with many of the underlying science fundamentals, equipment and system principles of nuclear electric generation, and that each participant will want to study different aspects of nuclear power plants to different degrees. As such, while the lectures will treat topics that are necessary for everyone to achieve the desired level of common understanding, it is left to the self-study sessions for each individual to pursue various topics to different depths. The Simulation and Problem Solving sessions are designed to ensure that the desired level of understanding is achieved by every participant. Any shortcomings identified during these sessions will be addressed during the review period, and if necessary will result in changes to the content of the lectures and/or the conduct of the self-study and simulation sessions.
