Amc: A Monte Carlo Code Utilizing the Albedo Approach for Calculating Neutron and Capture gamma-Ray Distributions in Rectangular Concrete Ducts

摘要

The report describes the AMC code and is intended to serve as a reference manual to be used with the code. This code can be used to calculate the fluxes and dose rates inside large rectangular ducts constructed of concrete walls that arise from neutrons of all energies incident upon the duct mouth. An option in the code allows a simultaneous calculation of the secondary gamma-ray dose rates arising from wall capture as well. The code treats duct transmission by employing the albedo concept in conjunction with a Monte Carlo treatment of history generation. The present description is limited to six distinct types of rectangular duct geometries, but includes ducts having up to three legs with two right-angle bends.
