Description

A fuelling study for CANDU reactors is conducted using natural uranium (NU) fuels doped with trace amounts of burnable neutron absorbers. The burnable absorbers of interest include gadolinium oxide (Gd2O3) and europium oxide (Eu2O3). The study incorporates fuel-lattice simulations as well as refuelling and core-following simulations to quantify the impact in the in-core behavior of the fuel. The fuel lattice simulations were conducted using the WIMS-AECL code while refuelling and core-following simulations were conducted using the Reactor Fuelling Simulation Program (RFSP). This paper presents the improvements in the safety margins gained by the use of burnable absorbers during normal operation. (author)
