Analysis of the TORT validation experiment
In a previous paper, calculations of a hypothetical concrete building by various discrete ordinates formulations and by Monte Carlo were compared. In general, agreement was good in areas directly affected by the source, but in areas completely shaded from the source by structural details, discrete ordinates showed more flux than did Monte Carlo. More recently, a model building has now been constructed and irradiated at the ORNL Tower Shielding Facility, allowing direct measurement of fluxes within the structure. The building calculations were performed with ORNL's three-dimensional discrete ordinates code, TORT, together with a 37-neutron, 21-gamma-group P/sub 3/ cross-section library derived from the VITAMIN-E cross section set. The validation experiment has supplied considerable insight into the strengths and weaknesses of three-dimensional discrete ordinates methods for such applications.
