Thermal/Hydraulics in PWR Fuel

Basic course for PWR fuel engineers and technical managers | taught by A.N.T. International

Course description


Engineers are taught in school the basic fundamentals of the physical process involved in nuclear power generation. Once employed in the industry, the specific design and requirements of the finished fuel product are observed through day to day activities. Often what is missing is a clear path linking the relationship of the physics to the finished product. 

The design of this course is to cover the basic physical laws related to nuclear fuel and show how these directly affect the design, analysis, and operation of both the fuel and related reactor systems. The discussion will show the links from the fundamental equations to the fuel design, through the cycle analyses, and culminating with the operating limits in PWRs. The course will focus mainly on the thermal-hydraulic and neutronics of the fuel but will also include key fuel rod mechanical items. In addition, a short discussion will show real life examples of how application of basic fundamentals can explain observed operating anomalies. 

The course is designed for engineers or technicians who work with any aspect of nuclear fuel design, analyses, or operation in PWRs, including both on site as well as support staff.

This course involves watching webinars. The course material can be accessed at times convenient for practicing engineers and managers. The PowerPoint-presentations are available for download on almost all lectures. You will find them just before the lecture starts.

Please note that these PowerPoint-presentations are the actual file from the seminar that has been recorded. Therefore, there may occur spelling errors and/or less perfect pictures or slides. As the presentations are the expert’s own material we have not edited them before making these lectures available online.
