THE SNAPKIN VI COMPUTER PROGRAM FOR SNAP REACTOR KINETICS CALCULATIONS

Description: S>The computer program SNAPWN VI is described which solves the space- independent reactor kinetics equations with feedback equations representing the principal shutdown mechanisms in a SNAP reactor. Reflector delay effects are treated by a reflector group model. By using an alternate main program and two alternate subroutines, spatially dependert feedback effects may be considered. Printed, CRT, and punchcard output may be obtained optionally. Sample problems are demonstrated for both versions … more

THE VOLATILITY OF UO$sub 1$ $sub 2$+-x AND PHASE RELATIONS IN THE URANIUM- OXYGEN SYSTEM

Description: The volatility of UO/sub 2 plus or minus x/ and the phase relations in the uranium-oxygen system were studied using thermogravimetric techniques. Chemical reactions describing the loss of uranium from UO/sub 2 plus or minus x/ at temperatures between 1100 and 2200 deg C in oxygen pressures between approximately 10 and 10/sup -6/ torr are proposed. The uranium-bearing vapor species above UO/sub 2 plus or minus x/ appears to be UO/sub 4/(g). Evidence supporting the existence of UO/sub 4/(g) inclu… more

GAMMA RAY PRODUCTION CROSS SECTIONS

Description: Gamma production cross sections are presented as a function of l6 neutron lethargy groups and 11 photon energy groups for 13 elements and isotopes. They were computed by the program GAMMA-P and account for the production of gamma rays by neutron radiative capture, neutron inelastic scattering, neutron induced fissioning, and (n, alpha ) reactions.

Compatibility of Unsupported Pyrolytic-Carbon Coated Uranium Dicarbide Particles With Water Vapor

Description: Five batches of pyrolytic-carbon-coated uranium carbide particles were exposed to partial pressures of water vapor ranging from 20 to 635 mm Hg at temperatures of 700 to 1100 deg C. All batches of coated particles had laminar type of coating and contained cores consisting principally of uranium dicarbide. The rate of reaction of the pyrolytic-carbon coatings with water vapor was determined from weight losses. The extent of failure of the coatings during exposure was established by microscopic e… more
