The criticality of a system containing fissionable materials is described by its effective multiplication factor ([k.sub.eff]).
The Table 1 shows the values of the effective multiplication factor of the same mesh size with the number of iterations (600-1000).
Iterations optimization and its corresponding maximum effective multiplication factor ([k.sub.eff]) with constant mesh size (4 cm x 4 cm).
In this model, factors such as effective multiplication factor, fissile material consumption, neutron flux, and power density are estimated.
The effective multiplication factor is also estimated for the three-dimensional model, based on the previously generated cross sections.
their reactivity (related to the effective multiplication factor) increases during the process.
The only concern in this case is the variation of the effective multiplication factor (k) that will be used to determine the reactivity according to equation 2:
The effective multiplication factors, [k.sub.eff], were analyzed for two cases corresponding to the complete withdrawal and the full insertion of control rods (four shim rods and one automatic regulating rod).
Numerical calculations were performed to analyze the effective multiplication factors, [k.sub.eff], for two cases corresponding to the complete withdrawal and the full insertion of control rods.
