Gamma-ray energy deposition measurements in the Fast Breeder Blanket Facility
Gamma-ray energy deposition measurements were made in a simulated fast reactor blanket of the Purdue University Fast Breeder Blanket Facility (FBBF) using CaF/sub 2/:Dy thermoluminescent dosimeters (TLDs). The TLDs were encased in either stainless steel or lead sleeves, and cavity ionization theory corrections known as f factors were used to relate the TLD dose to the sleeve dose. Corrections for the neutron response of the TLDs were made by determining the relative contributions of the TLDs neutron and gamma-ray responses. Radial experimental heating rates are presented and compared to calculations. The calculations significantly underestimate the experimental gamma-ray energy deposition rates in both stainless steel and lead. The underestimation is approx. =30% in stainless steel and approx. =15% in lead at the transformer/blanket interface and increases with increasing radius, reaching approx. =50% in stainless steel and approx. =40% in lead at the outside of the 0.51-m-thick blanket. This underestimation trend is attributed to a general underprediction of the ''bulk'' neutron population by the neutron flux calculations.
