Abstract

Abstract

Based on the annular fuel elements, a conceptual design of ultra-high flux reactor (UFR) is proposed. The fuel assembly design adopts a hexagonal assembly composed of 61 fuel elements. The core is designed with 52 boxes of fuel assemblies, 9 boxes of control rod assemblies and a thick reflecting layer. The key parameters such as the core cycle length, neutron fluence rate, neutron energy spectrum and neutron spatial distribution are given from the evaluation of the core conceptual design scheme. The results show that the maximum neutron fluence rate of the proposed ultra-high flux reactor can reach 1.0 × 10¹⁶ cm⁻²·s⁻¹under the current general parameters.
