  The n-d elastic and breakup cross sections are computed by solving the
three-body Faddeev equations for realistic and semi-realistic Nucleon-Nucleon
potentials. These cross sections are inserted in the Monte Carlo simulation of
the nuclear processes considered in the International Handbook of Evaluated
Criticality Safety Benchmark Experiments (ICSBEP). The results obtained using
thes ab initio n-d cross sections are compared with those provided by the most
renown international libraries.
