Influence of the ab initio n-d cross sections in the critical heavy-water benchmarks

► We solve the three nucleon problem using different NN potential (MT, AV18 and INOY) to calculate the Neutron-deuteron cross sections. ► These cross sections are compared to the existing experimental data and to international libraries. ► We describe the different sets of heavy water benchmarks for which the Monte Carlo simulations have been performed including our new Neutron-deuteron cross sections. ► The results obtained by the ab initio INOY potential have been compared with the calculations based on the international library cross sections and are found to be of the same quality.
