Preferential Pumping and Its Application to the P⁴ Experiment

Description: Report analyzing the "preferential removal of neutral gas from an incompletely ionized plasma in which the ionized particles are allowed to drift along magnetic field lines through a differentially pumped channel" and its relation to the P⁴ experiment. The report also analyzes the regenerative and non-regenerative losses of plasma by radial diffusion, as well as "considerations relating to the ultimate disposal of overflow plasma."

Dissociation of H₂⁺ by Photons

Description: Abstract: "A measurement was made of the dissociation of vibrationally-excited H2+ ions by photons having quantum energy in the vicinity of 4 e.v. The calculated cross section from theory is 3 x 10-(-18) cm-2. The experimental result is 10-(-17) cm-2; a factor of 10 uncertainty is present because the photon intensity was unknown by that factor."

100-B Area flow analysis

Description: Results of experimental programs indicate that it might be desirable in the future to modify the existing reactors by replacing the aluminum process tubes with tubes made of a zirconium alloy. The zirconium tubes would be more corrosion resistant than the aluminum ones and would also be stronger at higher temperatures. These new tubes would have the same outer diameter as the present tubes (for ease of handling and in order to provide adequate graphite cooling) but would have a thinner wall (si… more

The Effects of Nuclear Weapons

Description: This handbook prepared by the Armed Forces Special Weapons Project of the Department of Defense in coordination with other cognizant government agencies and published by the United States Atomic Energy Commission, is a comprehensive summary of current knowledge on the effects of nuclear weapons. The effects information contained herein is calculated for yields up to 20 megatons and the scaling laws for hypothetically extending the calculations beyond this limit are given. The figure of 20 megat… more

The Influence of Lubrication on the Compactability of Magnesium-Green Salt Blends for Bomb Reduction

Description: Lubrication of die surfaces with mineral oil or Dag 217 during final compacting of UF/sub 4/--Mg blends prevented seizing. Mineral oil application after every third press allowed 18 compacts before seizing became severe. Similar application of Dag 217 allowed 78 compacts. Mixing 0.33 wt.% Ceremul "C" with the powder allowed 40 compacts. Punch clearance had little effect on seizing. (T.R.H.)

ISOTOPIC EQUILIBRIA OF NITROSYL CHLORIDE

Description: The electrolytic solvent characteristics of liquid nitrosyl chloride and general consideration of the factors affecting suitability of a system for isotope separation suggest that exchange reactions of NOCl might provide an interesting and useful means for the separation of the stable isotopes of nitrogen or of chlorine, or of both in a simultaneous process. Vibrational frequencies of isotope substituted NOCl molecules are calculated and used to estimate equilibrium constants for exchange of ni… more

The Unified Soil Classification System, Appendix B: Characteristics of Soil Groups Pertaining to Roads and Airfields

Description: Report describing various kinds of soils and their characteristics, for use in constructing roads and airfields: "The properties desired in soils for foundations under roads and airfields and for base courses under flexible pavements are: adequate strength, good compaction characteristics, adequate drainage, resistance to frost action in areas where frost is a factor, and acceptable compression and expansion characteristics. Certain of these properties, if inadequate in the soils available, may… more

Weak Interactions

Description: Experimental results on the non-conservation of parity and charge conservation in weak interactions are reviewed. The two-component theory of the neutrino is discussed. Lepton reactions are examined under the assumption of the law of conservation of leptons and that the neutrino is described by a two- component theory. From the results of this examination, the universal Fermi interactions are analyzed. Although reactions involving the neutrino can be described, the same is not true of reactions… more

Fast-Period Reactor Safety Fuse Tests

Description: The combination of an effective fuse with a sensitive trigger is investigated. Tests conducted with two types of fuse, the annular-passage and the control-rod-type fuse, are described and analyzed. Appendixes present the methods of analysis and calculation, an analysis of fuse performance, and a summary of alternative fuse trigger and fuse system designs, with methods for adaption of fuses to power reactors.

A Martensitic Reaction for Uranium

Description: Hardness measurements of specimens quenched from the beta yields alpha phase at different cooling rates support the proposed martensitic beta yields alpha transformation for urnnium. Specimens held in 635 and 600 deg C isothermal baths prior to subsequent quenching to --5 deg C require more than 10 and two seconds, respectively before diffusion mechanlsms for beta yields alpha transformation commence. Once started, about 500 seconds are required to complete transformation by diffusion at these … more
