Neutron Flux Perturbations due to Infinite Plane Absorbers IV: The Exponential Flux Revisited

M. M. R. Williams

Nuclear Science and Engineering / Volume 140 / Number 2 / February 2002 / Pages 189-194

Technical Note

Flux depression factors and measures of asymmetry are presented for an absorbing and scattering slab in an infinite medium in which there is an overall exponential flux. One speed transport theory is employed. The effect of the slab on the exponential flux is determined and the necessary correction factors to recover the unperturbed flux from the activation of the slab are calculated. Although this is an old problem, we present here a new formalism which highlights clearly some important physical aspects.
