Tables are presented for calculating the reactivity transients that result from ¹³⁵Xe or ¹⁴⁹Sm poisoning in any thermal reactor that employs ²³⁵U as the principal fissionable material. Xenon and samarium concentrations are given as a function of time in units of absorptions per fission neutron. Tables are also given for the change in reactivity held in xenon after step reductions in power. Thermal flux is expressed in units of megawatts from thermal fissions per kilogram of ²³⁵U. These tables cover a range of power from 0 to 500 MW/kg.
