PhD Topic: Modeling Fully Ceramic Microencapsulated (FCM) fuel
Supervisor: prof. Wacław Gudowski (Royal Institute of Technology KTH, Sweden & NCBJ Poland)

The TRISO particle behaviour under irradiation in normal and accident conditions have already been modelled and it appears from comparison of experimental results on TRISO failures and calculations that failure mechanisms are rather well understood. The aim of the PhD is to conduct new experiments to determine the failure rate and causes of damage occurring in the TRISO particle and to validate better theoretical models. The benefit of this PhD will be to get a better understanding of the behaviour of the HTGR fuel in general and of the FCM fuel in particular, to possibly optimise the design and manufacturing of this fuel. Moreover, developed experimental procedures will be a foundation for quality control and quality assurance of the TRISO fuel for the polish HTR program.
