ion; San Diego, California, USA (16 Apr 1974). The objective of the present study is the identification of crosssection uncertainties which might produce uncertainties of the order of several percent in the tritium breeding ratio in fusion reactor blankets. The model chosen was the bench-mark configuuration specified at the Neutronics Session of the International Working Sessions on Fusion Reactor Technology. Using ENDF/B version 3 cross sections and an S/sub 4/- P/sub 3/ transport calculation, calculations of the effects of substantial cross section changes were performed both individually and in selected pairs which would leave the total cross section of an isotope unchanged. The cross sections most worth further study were the /sup 7/Li(n,n' alpha )t, the /sup 93/Nb (n,2n) and (n,n') reactions. (auth)
