Abstract
The Advanced Heavy Water Reactor (AHWR) is a 920 MWth, vertical pressure tube type thorium-based reactor cooled by natural convection by boiling light water and moderated by heavy water. In this paper, we present the isotopic and energy group wise contributions to the Fuel Temperature Coefficient (FTC) in AHWR using our first order perturbation analysis code. In AHWR, the contribution of 239Pu to FTC decreases with burn-up and the contribution of 233U in FTC becomes more negative with burn-up. Also 232Th gives a significant negative contribution, which makes the FTC become more negative with burn-up in AHWR.
