Synopsis:

The course is focused on inner nuclear fuel cycle of the nuclear power plants, particularly PWR used and / or planned in the Czech Republic. The first part of the course consists of introduction to the core physics, e.g. fuel changes during the cycle, burn-up, changes of keff during the cycle, xenon poisonings and xenon oscillations, samarium, etc. The second part of the course consists of NPP fuel cycle, fuel burn-up and fuel management, e.g. fuel handling, fuel management, reactor operation, burn-up, fuel loading, fuel reloading, loading pattern, legislative requirements for the core, core loading and fuel handling, fuel cycle of WWERs PWR, Fuel cycle of Dukovany & Temelín NPP, fuel cycle of western PWRs, BWR fuel cycle, CANDU fuel cycle. At the end of the course basic information about MOX fuel is mentioned. Note: Front-end & back-end of the nuclear fuel cycle of the nuclear power plants is the part of 17JPC - Nuclear fuel cycle course
