Summary
Pulsed neutron source measurements were made for a series of subcritical to critical loadings on a bare U/sup 235/ water assembly in slab geometry. For each loading, the assembly was repetitively pulsed, and the time distribution of thermal neutrons in the core was recorded on time analyzers. From these data, the reciprocal die-away time ( alpha ), the delayed neutron background, and the reactivity of the system were determined. Measurements at various positions in the assembly verified that spatial modes do not affect the reactivity determination. (auth)
