CANDU REAKTÖRLERİNDE ThC VE LWR YAKIT ATIĞI KARIŞIMI KULLANIMININ İNCELENMESİ

Öz

Bu çalışmada; ThC ve Hafif su reaktörü (LWR) yakıt atığı karışımının CANDU reaktörlerinde kullanılabilirliği ve reaktör performansına etkisi araştırılmıştır. Bunun için yakıt olarak % 100 UO₂, % 100 LWR yakıt atığı ve % 40 ThC + % 60 LWR yakıt atığı karışımı kullanılmıştır. Hesaplamalar tek boyutlu SCALE 4.4a bilgisayar sistem kodu yardımıyla yapılmıştır. Yapılan hesaplamalar sonucunda, k_¥ = 1.06 sınır değerinde bu yakıtlar için yanma dereceleri sırasıyla 7.700, 27.000 ve 11.000 MW.D/MT bulunmuş ve reaktör işletim süreleri 170, 660, 280 gün elde edilmiştir. Buna bağlı olarak, ThC ile LWR yakıt atığı karışımının doğal UO₂ yakıtına nazaran kritiklik ve yanma derecesi açısından çok iyi nükleer performans sergilediği görülmüştür.

Anahtar Kelimeler
