Course description:

The thermal-hydraulic design part of the course includes the primary heat transport system design of nuclear reactors, emphasizing reactor main components and characteristics. Review of design methods and system equations based on conservation of heat, momentum and mass, including adequate empirical design correlations, and critical heat flux and pressure drop calculation methods. Topics include: description of reactor components and systems, design methodology, plant performance, safety design margins, etc. The thermal-hydraulics analysis part of the course includes two-fluid two-phase modelling of thermalhydraulics phenomena in reactor heat transport system including modelling and simulation of postulated accidents. Topics include: two-fluid conservation equations and constitutive correlations, nodalization schemes and numerical methods applied in thermalhydraulic network simulation, equation of state and the rate method, computer code development, CATHENA computer code specific theory, numerical algorithm, and flow regime modelling.

Format: Nominally, three modules consisting of all day sessions for about 2 days each.
Prerequisite: Registration in the UNENE Master's degree program or its equivalent.

Preparing for the course:

• If you were a regular senior undergraduate or graduate student in Engineering at McMaster, then no special preparation would be necessary for taking this course. Any accredited undergraduate engineering program contains sufficient mathematics and physics for this course. The content needed is all in the course notes. It should not be necessary to look elsewhere for special background information. So relax on that point.
• However, there is a fair bit of mathematics (first and second order ordinary and partial differential equations) and some simple numerical methods to contend with.. If it has been a while since you have been in university and your mathematics has become a bit foggy, then you might want to first look over the course notes on this site to get a feel for what deficiencies you might have and then to dig out your old university texts to brush up. But don't panic, exotic mathematical manipulations and solutions are not expected; rather, the differenctial equations are used to express heat and mass flow balancesand provide simple, approximate solutions.
• Please do read ahead using the course notes supplied below. The compressed format does not give much time to think during the sessions but you can compensate somewhat by reading ahead.
• You will need to print off the notes given below so you can follow along in the lectures.
