    Abstract

    The application of the Monte Carlo method to the field of burn up calculations leads to powerful and accurate tools which are however quite demanding on calculation time because the reaction rates required for burn up calculations are always calculated within an MC code. Trying to solve this problem, we have formulated a more efficient approach to Monte Carlo burn up where we calculate the reaction rates outside the MC code. To demonstrate this, we have implemented it in ALEPH, a Monte Carlo burn up code using MCNP or MCNPX, ORIGEN 2.2 and NJOY 99.90. A decrease of a factor 30 in calculation time has been observed while the results obtained are in excellent agreement with the NEA/OECD Burn-up Credit Criticality Benchmark. It has also been shown that a statistical error of 0.5 % on the total flux in a cell is sufficient to obtain reliable results on the isotope composition.
