Monte-Carlo Calculations of Water-Scattered Fast Neutrons; ETUDE DE LA PROPAGATION DES NEUTRONS RAPIDES DANS L'EAU PAR DES METHODES DE MONTE-CARLO

Technical Report ·
OSTI ID:4259010
The exact trajectories of a number of neutrons (4,800) with initial energies ranging from 19.66 Mev to 300 kev were determined during the thermalization of neutrons in water. To determine the neutron life, the position, direction, and energy of neutrons are calculated for each collision by the use of random numbers associated with the pertinent probabilty laws. To improve the results, fill consideration was given to the first collision. The slowing down of the neutrons was determined, and the reflection of fast neutrons by the water and the neutron albedo was calculated. (J.S.R.)
