CORRELATIONS OF EXPERIMENTAL AND THEORETICAL CRITICAL DATA. COMPARATIVE RELIABILITY, SAFETY FACTORS FOR CRITICALITY CONTROL
Technical Report
·
OSTI ID:4076084
Correlations of computed and experimental critical data are discussed. The scope is limited to fissile systems that may be approximated by simple descriptions. The methods used to adjust data to uniform conditions are outlined. The requirements for computation where the values are intended to substitute for experimental data in nuclear safety guidance are described. Computational methods using DSN and multigroup diffusion techniques are discussed. Both computed and experimental data are given for the following: critical masses of bare spheres of uranium with various moderators, critical masses and volumes of homogeneous water-moderated uranium spheres, core-density exponents for water reflected-water moderated U/sup 2//sup 3//sup 5/ or Pu/sup 2//sup 3//sup 9/ sphere s, critical diameters of infinite cylinders of homogeneous water-moderated uranium, critical thicknesses of infinite slabs of homogeneous water-moderated uranium, critical masses of delta-phase plutonium mixtures with water and Plexiglas, influence of Pu/sup 2//sup 4//sup 0/ on critical mass of watermoderated plutonium spheres, critical diameters of infinitely-long cylinders and critical thickness of infinite slabs of homogeneous water-moderated Pu/sup 2// sup 3//sup 9/, critical volumes of U-C-H/sub 2/O systems, and critical masses of bare spheres of uranium diluted with other metals and graphite.
