Book Description
Previous work concerning cross-section sensitivity of the tritium breeding ratio showed ine effects of altering a partial cross section independently of other partial cross sections, permitting the total cross section to rise or fall. The results reported here are mostly for variations made while keeping the total cross section constant. The cases considered were for high and low values of the cross sections for /sup 6/Li(n,)t, /sup 7/Li(n, n' alpha)t, and for /sup 93/Nb(n2n) with compensatory changes in other cross sections. The general conclusions of previous work have been borne out both qualitatively and quantitatively under the present more realistic ground rules. In addition, results are reported for a modified CTR benchmark which has blanket material in place of the graphite reflector. This case shows a drop of 0.13 in /sup 6/Li productions, a rise of 0.02 in /sup 7/Li productions, and an increase of 0.15 in neutron leakage. (auth).

Book Description
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 S4- P3 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 7Li(n, n' alpha)t, the 93Nb (n,2n) and (n, n') reactions. (auth).
