KATIŞKISIZ UO2 YAKIT PELETLERİNİN İLK AŞAMA SİNTERLEME KİNETİĞİNİN İNCELENMESİ

Year 2018, Volume: 30 Issue: 2, 13 - 20, 25.12.2018

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.

INVESTIGATION OF THE FIRST STAGE SINTERING KINETICS OF ADDITIVE FREE UO2 PELLETS

Year 2018, Volume: 30 Issue: 2, 13 - 20, 25.12.2018

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.
