Abstract: The perturbation calculation for neutron integral transport equation in hexagonal geometry is studied in this paper. Based on the calculation for interface current method of neutron integral transport equation in hexagonal geometry and the calculation for corresponding mathematical adjoint equation, the perturbation theory is used to calculate the reactivity variety in reactor hexagonal assembly when the parameters of cell in assembly occurred minimal change. The calculation result is satisfactory. It proves that the perturbation calculation method developed in this paper is correct.
