Gamma-ray heating in the Fast Breeder Blanket Facility
Gamma-ray heating rates in both stainless steel and lead have been measured in the Fast Breeder Blanket Facility using CaF/sub 2/:Dy thermoluminescent dosimeters. The TLD responses in stainless steel or lead holders were corrected by applying spectral-weighted f-factors. Corrections for neutron responses were based on CaF/sub 2/ TLD neutron sensitivities. Radial experimental heating rates are presented and have been compared to results of a radial calculation performed as three seperate steps: a neutron diffusion calculation, a distributed gamma-production calculation and a gamma-ray transport calculation. The calculation underestimates the gamma-ray heating by 20% and 42% in stainless steel and by 1% and 32% in lead at the smallest and largest blanket radii respectively. The use of the multigroup method in blanket calculations seems to cause underestimations of several nuclear parameters in the outer blanket of the Fast Breeder Blanket Facility.
