Cyclotron Component Design Technical Reports

From introduction: The study of cyclotron-magnet design presented here is directed toward attaining a large ratio of energy in the ion beam with respect to cost. Alternatively, the goal may be regarded as a smaller, more convenient apparatus. These two objectives are not completely incompatible; a design that is more economical than the usual is also smaller. The best design of a cyclotron can be obtained only by considering the problem as a whole. The conditions necessary to maintain an ion beam, the conditions required for the operation of the oscillator, and a host of other problems influence the design of the magnet. It is assumed in this paper that the "other problems" can be satisfactorily solved, if the gap has a suitable geometry and the field a suitable space dependence.

Dynamic Response of Reactor Plant to Load Changes. Section I. First Performance. Core I, Seed 1. Test Results DL-S-251 (T-612390)

The purpose of the test was to determine the responses of the plant when subjected to load transients exceeding the design magnitudes, and to determine the maximum load changes, positive or negative, that the plant can sustain. The reactor plant responded satisfactorily to all load transients. The only limits exceed were the pressurizer high and low level alarm points. The magnitude of the transients and the time required for the plant to return to equilibrium was dependent upon the size of the the load change. The pressurizer spray was effective in reducing reactor coolant pressure positive surges; however, this resulted in larger negative surges than when the spray valve was closed.

Metallurgy Division Quarterly Progress Report for Period Ending July 31, 1951

Technical report outlining the effect of strain rate on the tensile properties of thorium. It has been found that the yield strength increases slightly with increasing strain rate, and that tensile strength increases but to a less extent. Studies on the fabrication of thorium by extrusion and drawing have continued, as have studies on the extrusion cladding of thorium and uranium with zirconium. [From Summary}

The Distribution of Calcretes and Gypcretes in Southwestern United States and Their Uranium Favorability: Based on a Study of Deposits in Western Australia and South West Africa (Namibia) (open access)

The Distribution of Calcretes and Gypcretes in Southwestern United States and Their Uranium Favorability: Based on a Study of Deposits in Western Australia and South West Africa (Namibia)

From summary: The procedure has been to search for areas in which nonpedogenic calcrete or gypcrete may have developed and where additional study or exploration might be justified.
