Measurements were made of the reactivity changes caused by reflectors of various materials on BeO-moderated, U/sup 235/-fueled subcritical systems with a moderatorto-fuel ratio of 247. The reflector materials included aluminum, steel, copper, brass, type 304 stainless steel, nickel, Rene 41, Hastelloy R-235, and BeO. The pulsed neutron technique was used. The data are tabulated in terms of the subcritical time constant as a function of reflector thickness and surface density. (auth)
