Abstract: THE NEUTRON ABSORPTION AND MULTIPLICATION PARAMETERS ARE DETERMINED FOR HEAVY WATER (D2O) OR GRAPHITE MODERATED HETEROGENEOUS POWER REACTORS BY IRRADIATING A SINGLE FUEL ELEMENT CLUSTER POSITIONED ALONG THE LONGITUDINAL AXIS OF A GIVEN COLUMN OF MODERATOR AND TAKING NEUTRON FLUX MEASUREMENTS AT SUITABLE RADIAL AND AXIAL POSITIONS. THE CRITIAL DIMENSIONS AND POWER DISTRIBUTION FOR A HETEROGENEOUS CORE MADE UP OF A PLURALITY OF FUEL ELEMENT CLUSTERS OF THE TYPE IRRADIATED ARE DERIVED FROM THE NEUTRON FLUX MEASUREMENTS BY MEANS OF THE SO-CALLED "SOURCE-SINK" HETEROGENEOUS REACTOR THEORY.

Abstract: A polyethylene is disclosed that is modified by copolymerizing ethylene with a comonomer consisting of a minor quantity of a polycyclic polyene having at least three double bonds in the molecule, and preferably an endomethylenic bridge, so that it can be readily cross-linked under the influence of heat without the presence of an additive, but which still exhibits the characteristics of a conventional crystalline polyethylene.
