The decrease in HRE-3 breeding ratio due to the presence of the Zircaloy core tank and shroud was examined as a function of metal thickness and spacing. For the case of a 1/2-in. thick core vessel and a 1/2-in. thick shroud spaced 5 in. apart, the breeding ratio would be 0.047 less than if there were no Zircaloy present. The absorption cross section used for Zircaloy-2 is consistent with an experimentally measured value and an estimate based on spectrographic and chemical analysis of HRT core tank material. The fraction of blanket power generated in the space between core tank and shroud was also determined. (auth)
