The Mg-MgCl2 System — A Chronopotentiometric Study

Description: The mode of dissolution of magnesium in molten magnesium chloride contacted with Mg-Pb alloys was studied at 750°C using anodic chronopotentiometry. An inert tantalum anode was used to determine relative amounts of magnesium dissolved in its chloride as a function of magnesium activity in the alloy. According to the law of mass action a linear dependence of magnesium solubility on a Mg indicates Mg2Cl2 as the reaction product and a parabolic dependence indicates MgCl. It was found that the amou… more

Cosmic Ray Produced Ar37 and Ar39 Activities in Recently Fallen Meteorites

Description: Several methods of determining meteorite ages depend ages upon nuclides formed by cosmic ray interactions. The tactic assumption is always made that the intensity of cosmic radiation does not vary in time or space. However it is known that the intensity of cosmic radiation at the earth varies with the solar activity. The spectrum of cosmic ray protons and alpha particles exhibit a marked drop at the low energy end (<1.5 GeV) and the intensity in the region appears to follow the 11 year cycle of… more

The Status of Meteorological Knowledge as a Factor in Air Pollution Control

Description: The first national Technical Conference on Air Pollution (1) held in this city in 1950 included eight papers on meteorology; the present session contains one. On this basis, one night conclude that recent progress in meteorology has been virtually nonexistent or that the importance of meteorological factors has been diminishing, Neither could be further from the truth, as the number and quality of papers relating to air pollution meteorology in recent scientific and technical sessions will atte… more

Project CLEER: A study of the heat transfer characteristics of a capillary wetted surface

Description: An experimental program (Project Cleer) was initiated to investigate the heat transfer characteristics of a surface covered with a wick-like material and cooled by a capillary liquid. The preliminary heat transfer analyses developed and the measuring equipment and methods to be used are discussed. (LCL)

Review of literature on catalytic recombination of hydrogen--oxygen. [Removal of hydrogen from containment atmosphere following LWR blowdown]

Description: The results are reported of a literature search for information concerning the heterogeneous, gas phase, catalytic hydrogen-oxygen recombination. Laboratory scale experiments to test the performance of specific metal oxide catalysts under conditions simulating the atmosphere within a nuclear reactor containment vessel following a loss-of-coolant blowdown accident are suggested.

Portable monitor for tritium in air

Description: A portable monitor has been developed which accurately measures tritium concentrations between 1 x 10/sup -4/ and 1 x 10/sup -1/ ..mu..Ci/cc of air. The instrument consists of five basic sections: air pump, deionizer, ionization chamber, logarithmic electrometer amplifier, and high voltage power supply. An internal rechargeable 12-volt battery powers the entire monitor. A connector is provided so that an external 12-volt battery can be used if the monitor is needed for extended periods of time.… more
