Abstract

The neutron spectra in a cell of a heterogeneous subcritical system are investigated in detail. The neutron spectra were measured by means of a mechanical velocity selector and a time analyzer. A water-cooled water-moderated reactor (WWR) was used as the neutron source for the subcritical system. The results indicate that the neutron spectrum differs from the Maxwell equilibrium distribution both in the uranium and in the moderator. The neutron spectrum changes sharply at the boundary between the uranium block and the moderator. The spectrum varies only slightly within the block and within the moderator. A simple semiempirical functional relationship is found to exist between the thermal neutron spectra in the moderator and in the block.
