Outgoing neutron spectrum from H2O In a H20-uranium interface

Abstract

The outgoing fherm al neutron spectrum from H2O in a H2O - metal uranium (0.4 % U 235 depleted) slob interface has been measured using standard time-of-flight techniques. The experimental flux was compared with calculations performed with a modified version of the DTF-IV code in Sg, Pq and P approximations. The ENDF/GASKET scatterlng kernel for H2O was used in conjunction with the GGC -3 cross-section data for uranium. The P q approximation proved to be satisfactory for the spectra studied.
