Thermal-Neutron Steady-State Spectra in Pure and Poisoned Light Water Assemblies

Thermal-neutron steady-state spectra, in the presence of a 1/E epithermal source of neutrons, calculated in pure and poisoned light water assemblies, using the recent neutron scattering kernel of water suggested by Bansal et al., are found to agree with the recent experimental results of Abbate et al. The effect of different source terms on the steady-state spectra has also been studied.
