Abstract

The knowledge of fast neutron attenuation at great penetration depth is very important in reactor shielding analysis. To validate cross section libraries and radiation transport codes several clean, single material benchmarks have been performed. For two of the most important materials, namely iron and sodium, neutron deep penetration measurements were carried-out at the Pavia EURACOS facility. Using a plane fission disk source the fast neutron propagation was measured by means of the 32-S(n,p)32-P threshold reaction in a large block of iron (145 x 145 x 130 cm**3) and sodium (180 x 200 x 390 cm**3). The quantity of the irradiated sulphur detectors ranged from 1 to 500 grams.
