Abstract: The cross section deformation of hexagonal fuel-assembly duct in fast reactor, including elastic deformation due to the coolant pressure, the expansion of temperature growth and the creep and swelling deformation of neutron irradiation, is associated with the correct judgment of contact between different fuel-assemblies. It is a fundamental work to further determine the entire deformation of all fuel-assemblies. The purpose of this paper is to study the calculation method of the deformation, which is caused by temperature and irradiation. Based on theoretical analysis, a formula to calculate thc deformation is developed, whose elastic part is compared with and verified by those of finite element method. The yielded results will pave the way for the future further study.
