Integral form of nuclide generation and depletion equations for Monte Carlo simulation. Application to perturbation calculations

The general integral form of the nuclide generation/depletion equation suitable for a resolution by the Monte Carlo method is presented. A formal analogy between particle transport and nuclide generation/depletion is shown. Moreover, the Monte Carlo formulation of the nuclide generation/depletion problem allows to do perturbation calculation by using the correlated sampling method.
