High plant efficiencies can be realized without excessively high core temperatures and high coolant pressures by the use of liquid metal coolant. In an attempt to prove the feasibility of liquid sodium as a reactor coolant ALCO Products, Inc., under sponsorship of the Atomic Energy Commission, is undertaking a design study of three vital system components: the intermediate exchanger, the boiler, and the superheater. Since, in the past programs, the nuclear reactor had been the major focus of attention, the development of the sodium cooled reactor and sodium pumps for this application are thought to need the less development than the heat exchanger equipment. Consequently, parallel design studies of the reactor, pumps, and other system components have not yet been initiated.</p>Control of Fires in Inactive Coal Formations in the United States2010-02-21T23:09:24-06:00https://digital.library.unt.edu/ark:/67531/metadc12744/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc12744/"><img alt="Control of Fires in Inactive Coal Formations in the United States" title="Control of Fires in Inactive Coal Formations in the United States" src="https://digital.library.unt.edu/ark:/67531/metadc12744/small/"/></a></p><p>From Introduction: "The purpose of this Bulletin, in addition to presenting a history and description of Bureau activities in controlling these fires, is to provide the mining industry and the public with information concerning methods of controlling fires in inactive coal formation.

The state of each atom is specified by a two-valued variable, which may be identified with: (1) its spin (up or down), if one wishes to describe a magnetic system; (2) its identity (A or B), if one wishes to describe a a mixture of two kinds of atoms; or (3) its presence or absence (atom or hole), if one is dealing with a lattice gas. In all three cases it is assumed that the energy of a configuration of the system, aside from the energy of interaction with external fields, is simply a sum of energies of nearest-neighbor pairs, the energy of a pair being zero if the two atoms are similar, and the sum if they are different. In describing the calculations, we shall use the terminology appropriate to (2), but the results will be general statements about the model.</p>The Crystal Structure of LiCuCl3-2H2O*2019-08-27T15:53:11-05:00https://digital.library.unt.edu/ark:/67531/metadc1201465/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1201465/"><img alt="The Crystal Structure of LiCuCl3-2H2O*" title="The Crystal Structure of LiCuCl3-2H2O*" src="https://digital.library.unt.edu/ark:/67531/metadc1201465/small/"/></a></p><p>This report undertakes research to study LiCuCl3-2H2O is from a structural standpoint, revealing the oxygen positions.

The means by which their roof and wall surface would contain a pressure buildup 0.3 psi, and prevent contaminant release which might accompany a nuclear incident are discussed. Prototypes of the B, D, DR, F, and H reactor block wall configuration, the corrugated transite roof of the K reactors, and the corrugated transite walls of the K and C reactors are evaluated. Methods of securing certain building components are described, and a comparison of several candidate sealant coatings presented for consideration. These tests were performed at the request of the Design Operation, as part of CG-791, an existing reactor containment program. This series of tests represents only a part of the overall modifications program. A study of the reactor building containment design criteria is available in a Hanford document, HW-59236, by T. O. Brown.</p>Final Report Chicago Operations Office Steam Separation Program, February-March, 19602022-05-24T06:07:15-05:00https://digital.library.unt.edu/ark:/67531/metadc1257944/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1257944/"><img alt="Final Report Chicago Operations Office Steam Separation Program, February-March, 1960" title="Final Report Chicago Operations Office Steam Separation Program, February-March, 1960" src="https://digital.library.unt.edu/ark:/67531/metadc1257944/small/"/></a></p><p>A program of free-surface steam-water separation at 600 psig was carried out in support of the design for operation of the Experimental Boiling Water Reactor at 100 MW thermal.

In a high level irradiation test, cracks developed in the coatings of specimens coated with pyrolytic carbon and siliconized silicon carbide. In another high level irradiation test, a graphite sphere fueled with Al2O3 coated with UO2 particles is showing excellent fission product retention. The leakage factors (i.e. rate of release/rate of production) for long lived volatile fission products such as Kr85m, Kr87, Kr88, Xe133, Xe135 are ranging from 10 to the negative 9th to 10 to the negative 6th. If this degree of fission product retention is maintained in a large power reactor, it would result in essentially a "clean" primary loop.</p>Fuel Element Development Program for the Pebble Bed Reactor2021-09-02T16:26:22-05:00https://digital.library.unt.edu/ark:/67531/metadc1463125/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1463125/"><img alt="Fuel Element Development Program for the Pebble Bed Reactor" title="Fuel Element Development Program for the Pebble Bed Reactor" src="https://digital.library.unt.edu/ark:/67531/metadc1463125/small/"/></a></p><p>A variety of spherical uranium-graphite fuel elements were fabricated with the objective of meeting the requirements of the Pebble Bed Reactor. Major emphasis was on silicon-silicon carbide coatings, pyrolytic carbon coatings and alumina coated fuel particles. An exploratory program on the limits of thorium oxide loadings by the infiltration process was started.Poor results with sintered alumina coated UO2 particles led to development work on alumina coating by vapor deposition for which the results have been most encouraging. A wide variety of sub-surface metal, metal carbide, and ceramic coatings located between an unfueled graphite shell and the fueled core of a PBR fuel element were prepared and examined.</p>Geography, Geology, and Water Resources of the National Reactor Testing Station, Idaho: Appendix 2, Basic Hydrologic Data2015-02-26T16:50:55-06:00https://digital.library.unt.edu/ark:/67531/metadc100250/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc100250/"><img alt="Geography, Geology, and Water Resources of the National Reactor Testing Station, Idaho: Appendix 2, Basic Hydrologic Data" title="Geography, Geology, and Water Resources of the National Reactor Testing Station, Idaho: Appendix 2, Basic Hydrologic Data" src="https://digital.library.unt.edu/ark:/67531/metadc100250/small/"/></a></p><p>Graphs and tables summarizing detailed discharge data of the Big Lost River.</p>Geologic Appraisal of Dimension-Stone Deposits2017-01-14T22:15:59-06:00https://digital.library.unt.edu/ark:/67531/metadc304319/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc304319/"><img alt="Geologic Appraisal of Dimension-Stone Deposits" title="Geologic Appraisal of Dimension-Stone Deposits" src="https://digital.library.unt.edu/ark:/67531/metadc304319/small/"/></a></p><p>From abstract: The construction stone industry comprises two major branches-dimension stone and crushed and broken stone. For purposes of geologic appraisal, deposits of these two categories should be treated separately, because they differ widely in use, mode of development, and exploitation. Deposits of dimension stones are subjected to much greater selectivity with respect to physical properties, uniformity, and modes of occurrence; these demand a much more critical and
