MCNPX vs Handbook Calculations for Radiation Streaming in the SNS Target Carriage
The movable carriage has been designed to support the mercury target in the Spallation Neutron Source in a cantilevered fashion, and to supply the mercury flowing to and from the target. As a part of design process, the fluxes and dose rates in the hot cell downstream of the carriage have been analyzed. The transport of radiation from the proton beam, which hits the mercury target, to the hot cell downstream of the carriage is a specific task that includes solving of both deep penetration and streaming problems. The handbook analyses and MCNPX analyses using different techniques have been performed. The comparisons of the MCNPX results and handbook results show that both are in good agreement and that the handbook analyses are reliable for the first estimation.
