Abstract

In this study, utilization of ThC and LWR spent fuel mixture in CANDU reactors and its effect on reactor performance were investigated. For this purpose, fuels, namely % 100 UO2, % 100 LWR spent fuel and the mixture of % 40 ThC+ % 60 LWR spent fuel were used. Calculations were done with the aid of one dimensional computer system code of SCALE 4.4a. According to calculation results, by taking $k_{infty}$= 1.06 as reference limit, burnup grades were found as 7.700, 27.000 and 11.000 MW.D/MT and reactor operation periods were obtained as 170, 660 and 280 days for these fuels, respectively. Therefore, the mixture of ThC and LWR spent fuel showed better nuclear performance than natural UO2 fuel with respect to criticality and burn up grade.

Özet

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, $k_{infty}$ = 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.
