Experimental and computational studies of the gamma-ray energy deposition rate in the Purdue Fast Breeder Blanket Facility
The Purdue University Fast Breeder Blanket Facility (FBBF) is a source-driven facility which provides an absolute basis for calculation and experiment (C/E) comparisons. Experimental and computational studies of the gamma-ray energy deposition rate in the FBBF were performed to look for more improved experimental and computational methods. Measurements were made with thermoluminescent dosimeters (TLDs). Various corrections including the TLD neutron sensitivities and the f-factors (general cavity-ionization theory) were applied to the TLD measurements. Calculations were performed primarily with three computer codes - 1DX, 2 DB, and ANISN - and two nuclear libraries - LIB-IV and EPR. Both neutron and gamma-ray calculations were included. The previously reported deviations between the gamma-ray energy deposition C/E ratios for lead and for stainless steel were resolved by increasing the stainless steel sleeve thickness to attenuate the electrons produced in the surrounding field. The previous deviation between the gamma-ray energy deposition C/E ratios and the /sup 238/U capture C/E ratios were resolved by calculational improvements that conserved the gamma-ray energy yield.
