TABLES OF REACTIVITY VS. PERIOD FOR U$sup 235$, Pu$sup 239$, AND U$sup 23$$sup 3$
S>Experimentally measured periods can be used in conjunction with the inhour equation to calculate corresponding reactivity changes. Tables of reactivity vs. period were computed on three fuels, based on new (1957) delayed neutron dala published by Keepin, Wimett, and Zeigler. There are two tables for each fissionable isotope: one based on the original Keepin, Wimett, and Zeigler data and the other based on a modification of this data. The original data were modified by slightiy increasing the delayed neutron fractions to account for the difference in the non-leakage probability occurring between prompt and delayed neutrons in thermal reactors. With the computed values in this report, experimental periods can be related to reactivity. (auth)
