The GPT method allows to calculate the sensitivity coefficients to any perturbation. Full Jacobian of sensitivities, cross sections (XS) to concentrations, may be obtained. The time dependent XS is obtained by combining the GPT and substep methods. The proposed GPT substep method considerably reduces the time discretization error. No additional MC transport solutions are required within the time step.
