The paper states a consistent approach to computing nuclear reactors using methods, which initial approximations meet the requirements of design calculations in a speed of operation, therewith computational results may be comparable with reference in accuracy. The first is the method of surface pseudosource used to calculate cells characteristics. The second is the method of surface harmonics used to calculate both fuel assemblies and the whole reactor on coarse grids. The paper gives a brief description of the methods and gives their applications for calculating VVER-type reactors and PWR benchmark.
