An integral experiment has been performed for verification of radiation transport methods used in the design of the exit shield for the proposed gas-cooled fast breeder reactor demonstration plant. The experiment was conducted at the ORNL Tower Shielding Facility and consisted of integral and spectral measurements of the neutron flux transmitted through prototypic mockups of exit shield assemblies and a control rod assembly. The experiment was intended to confirm the predicted effectiveness of the proposed shield design, and to investigate neutron streaming characteristics in the vicinity of a control rod assembly. The analysis was performed using discrete-ordinates and Monte Carlo transport methods and cross section data which are currently used for fast reactor shield design.
