Abstract

Canadian Deuterium-Uranium Reactor (CANDU) and Light Water Reactor (LWR) have significant share on supplying world energy. LWRs use low enriched uranium fuel with ~3.5% $^{235}U$ whereas CANDU utilizes natural uranium fuel with ~ 0.71 % $^{235}U$. In this work, neutronic performance of CANDU reactor, temporal change of fissile fuel breeding and fission power production were investigated in the CANDU reactors with different uranium $(UO_2,Uc,U_3Si_2)$ fuels. Calculations were done with the aid of one dimensional computer code of SCALE 4.4a. According to calculational results, by taking $k_{\infty}$ = 1.06 as reference limit, burnup grades were found as 7700, 8900 and 7400 MW.D/MT and operation periods were obtained as 170, 260, 190 days for these fuels, respectively. According to these results, UC fuel showed better nuclear performance than natural $UO_2$ and $U_3Si_2$ fuel with respect to criticality and burn up grade.

Özet

Kanada Döteryum Uranyum (CANDU) reaktörleri ve Hafif Su Reaktörleri (LWR) dünya enerji ihtiyacının karşılanmasında önemli bir paya sahip olan fisyon reaktörleridir. LWR’lerde yakıt olarak zenginleştirilmiş uranyum yakıtı (~% 3.5 $^{235}U$) kullanırken, CANDU reaktörlerinde doğal uranyum (~% 0.71 $^{235}U$) kullanılmaktadır. Bu çalışmada, farklı uranyum $(UO_2,Uc,U_3Si_2)$ yakıtları kullanılarak CANDU reaktörünün nötronik performansı, fisyon olabilen yakıt üretimi ve nükleer güç üretiminin değişimleri incelenmiştir. 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 7700, 8900 ve 7400 MW.D/MT elde edilmiş ve işletim süreleri 170, 260, 190 gün bulunmuştur. Burada UC yakıtının, doğal $UO_2$ ve $U_3Si_2$ yakıtına oranla kritiklik ve yanma derecesi açısından çok iyi nükleer performans gösterdiği tespit edilmiştir.
