Abstract
Sensitivities of steel displacements-per-atom (dpa) rates to fluence-rate spectra in regions of the Experimental Breeder Reactor II (EBR-II) are presented. Low sensitivities in EBR-II of ratios of dpa-to-fission rates assuming 240Pu as a dosimeter suggests its possible use for adjusting calculated dpa-rates for effects of errors in calculated fluence-spectra. Extension of the method to outer regions, having more degraded spectra, by use of 10B-shielded 240pu dosimeters is also suggested.
