The continuous-energy resonance self-shielding calculation method based on wavelets scaling function expansion method is a valuable potential method to solve the complex resonance problem. Within the fast and thermal energy ranges, the standard multi-group treatment is applied, while Daubechies’ wavelets scaling function expansion method is used to discretize the energy variable of neutron flux within the resonant energy range. In this method, the neutron transport equation is transformed to a set of expansion coefficients equations of wavelets scaling functions. Calculation of the coefficients is very time consuming so that a powerful neutron transport calculation method is needed for better calculation efficiency. In this paper, the discrete direction probability method (DDPM) is employed as a tool for solving the wavelet scaling function expansion coefficients. The DDPM combines the desirable features of interface current method as well as the method of characteristics.
