Abstract:

An experiment was conducted at the Oak Ridge National Laboratory Tower Shielding Facility during FY 1984-85 to provide verification of a discrete ordinates Three-Dimensional Oak Ridge Transport computer code TORT, which is being developed at ORNL for calculating the neutron and gamma-ray fluxes within concrete structures that were exposed to radiation at Hiroshima and Nagasaki. In the experiment a collimated beam of radiation from the Tower Shielding Reactor II, modified to represent the spectra of neutrons and gamma rays emitted in weapons bursts, impinged on a concrete structure simulating a small, simple, single-story concrete block house. Variations in the structure were introduced during the experiment by successive changes in the outer wall and within the building several blocks in the front wall were removed to form a window a concrete support pillar within the building was relocated and a central concrete wall was added to divide the single room into two rooms of approximately the same dimensions. Integral neutron fluxes and gamma-ray energy depositions were measured both in the modified reactor beam and at selected locations inside each structure. This report describes the experiments and presents the detailed results in both tabular and graphical form. It also discusses the impact of the variations in the basic configuration on the measured results. Author
