Multiple Reactivity Calculation Using Single Correlated Sampling Monte Carlo Simulation
نویسنده
چکیده
Correlated sampling technique has been applied to the ssion matrix approach for Monte Carlo eigenvalue calculation of reactivities ((K) due to small cross-section perturbations. The reference Monte Carlo simulation is performed in a system diierent from both the unperturbed and perturbed systems. This allows the determination of multiple Ks due to multiple cross-section perturbations with a single Monte Carlo simulation and a corresponding signiicant reduction in computational eeort. The method has been tested for one energy group transport problems with isotropic scattering.

Monte Carlo correlated sampling technique has been combined with the ssion matrix method to calculate reactivity perturbations due to small changes in cross-sections. The actual Monte Carlo simulation is done in a reference system diierent from both the unper-turbed and perturbed systems. This approach allows to correlated the unperturbed system and multiple perturbed systems to the reference s...
