Abstract
Bu çalışmanın amacı katışkısız UO2 yakıt peletlerinin birinci sinterleme kinetiği ve aktivasyon enerjilerinin incelenmesidir. UO2 ve U3O8 ilave edilmiş UO2 yakıt peletleri toz metalurji yöntemiyle üretilmiştir. UO2 ve U3O8 ilave edilmiş UO2 yakıt peletleri dilatometrede, Ar+%5 H2 atmosferinde sinterlenmiştir. Aktivasyon enerjilerini hesaplamak için sabit ısıtma hızı yöntemi kullanılmıştır. Ayrıca, sinterlenen peletlerin özelliklerine U3O8 etkisi incelenmiştir.

Abstract
The purpose of this study is to investigate the first stage sintering kinetics and to calculate activation energy of additive free UO2 pellets. UO2 pellets and U3O8 added UO2 pellets were fabricated by powder metallurgy route. Pellets were sintered in the Ar+ 5% H2 atmosphere using a dilatometer. Activation energy calculations carried out by constant heating rate. The influence of U3O8 addition on the properties of sintered UO2 pellets was also investigated.
