The void effect is one of the most important phenomena linked to safety criteria. The presence of a coolant void and high absorption in a reactor core restricts validity of the diffusion approximation in calculations. The classic method used for averaging neutron cross sections in these cases does not offer a satisfactory solution, while transport and Monte Carlo methods are not acceptable in routine applications. New techniques based on space-energy core homogenization, such as the SPH method or the discontinuity factor method, are proposed instead.
