摘要
Efficacy of the forward-adjoint Monte Carlo coupling technique, which is characterized by forward-and-adjoint-fluxes folding, has been investigated to accurately calculate shielding characteristics with less computer time in complex geometry, including a long streaming path from source to detection point. The fundamental formulas for detector response and statistical error calculations are given. Sample calculations for neutrons streaming through a mockup geometry of a sodium duct penetrating an iron shield clarify that the coupling technique is several times faster than the ordinary Monte Carlo method. © 1990 Taylor & Francis Group, LLC.
