Final Analysis of the GCFR Radial Blanket and Shield Integral Experiment

摘要

An integral experiment has been performed for verification of radiation transport methods and nuclear data used in the design of the radial 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 and gamma-ray flux transmitted through slabs of materials which modeled a GCFR-type radial blanket and radial shield. Both UO sub 2 and ThO sub 2 blankets were investigated as well as several shield designs comprising stainless steel, graphite, and boronated graphite. (ERA citation 06:016846)
