Abstract:

 

Frequently, the neutron transmission through the shields used for protection against radiation is an unavoidable phenomenon, so we have interested in this work to study the neutron transmission through shields. We have considered an infinite homogenous slab witch characterized by his scattering probability noted Ps, with a different thickness and an infinite plane source of neutrons which arrived on the left side of the slab and on the right side detector with fixed window is placed to detect transmitted neutrons and evaluate the neutron transmission probabilities. We used the simulation Monte Carlo method for sampling the neutron history in the slab and in order to accelerate the calculation convergence we have developed a new multi-parameters spatial biasing technique with 4 parameters. For each thickness of the slab and for several values of Ps we have determined the detector response and calculated the neutron transmission probability. We compared our result by results obtained with the spatial biasing technique with 2 parameters and 1 parameter. Then we have determined the FOM (Figure of the Merit) for each method. We can also notice that our method presents bests results by obtaining the greatest FOM for a large thickness of the slab having high scattering probability Ps.
