RESONANCE ABSORPTION IN A SLAB WITH A PARABOLIC TEMPERATURE DISTRIBUTION
Technical Report
·
OSTI ID:4264395
The idealized problem of a plane beam of neutrons impinging on a slab of U/sup 238/, across which the temperature has a parabolic distribution with a maximum at the center of the slab, is investigated. The calculations are based upon a simplified model of the U/sup 238/, resonance structure, and scattering in the material is neglected. It is concluded that, for a 1/E spectrum of incident neutrons, the resonance absorption will be the same as when the slab is at a uniform temperature which differs from the arithmetic mean of the parabolic distribution by less than 8% of the difference between the maximum and minimum temperatures.
