Effects of Overpressures in Group Shelters on Animals and Dummies

Description: S>Relative biological hazards of blast were studied in two types of communal air-raid shelters during Shots 1 and 8. Dogs, restrained within the shelters during detonation, were studied pathologically and clinically for blast injuries. Two anthropometric dummies were test objects for displacement studies utilizing high-speed photography. Physical data included pressure vs time and air-drag determinations. During Shot 1, animals sustained marked blast damages (hemorrhages in lungs and abdominal … more

The Effectiveness of Spray Cooling

Description: Abstract: "A possible method of cooling a liquid-fuel reactor is by spraying liquid metal through the liquid fuel, and then circulating the liquid metal through a heat exchanger. To evaluate the effectiveness of this cooling method, a few simple experiments were made with mercury sprayed through water. On the basis of the results, it was concluded that this method was intrinsically a low-power-density method, which could not find application except where a low fissionable-material inventory was… more

Dynamics of the Supercritical Water Reactor

Description: From introduction: "The work described in this report was carried out as part of the feasibility study (ORNL-117) of a supercritical water reactor (SCWR) for use in nuclear propulsion of aircraft. The object of this work was to study the dynamic behavior of a particular design of supercritical water reactor. Numerical results are presented in Appendix I."

Inspections performed by Du Pont on the telescope actuator system: Part 4

Description: Five telescope actuator systems designated as ``R``, ``P``, ``L``, ``K`` and ``C`` were fabricated at New York Ship. All five were similar in specifications except for minor detail. For overall assembly refer to du Pont arrangement drawings W-153422, W-153423, and W-153424. These drawings illustrate ``R`` unit; however, they are representative of all units. They show a complete listing of material required and an overall view of the telescoping assembly. Since jigs and special tooling were set … more

Precipitation of plutonium(IV) oxalate in Task I

Description: Laboratory experience on the precipitation of Pu(IV) oxalate is summarized. Filterable Pu(IV) oxalate with a cake density of 0.6 to 0.7 g Pu/cm/sup 3/ cake was precipitated from Redox PR solutions containing 10 to 200 g/l Pu and 2 to 6 M HNO/sub 3/. Filtration ease increased with strike temperature from 35 to 60/sup 0/C. Optimum conditions for pre-reduction of Pu(VI) to (IV), precipitation, digestion, filtration and washing were determined for 60 g/l Pu. Separation factors of 80, 40, 20, and 12… more

Radiation exposure rates in the 222-S Process Control Laboratory

Description: The objective of this study is to provide a simple method for calculating exposures for the various laboratory procedures which involve penetrating radiations. With this method it will be possible to evaluate and record on a day to day basis the total exposure received during laboratory work. It will also provide reliable information for exposure investigations.

Estimation of Lung Dose from the Radioactive Cloud Associated with a Nuclear Detonation

Description: A method is developed for estimating the dose to the lungs of a person exposed to the airborne radioactive dust from the cloud associated with a nuclear detonation. The analysis is applied to data collected at a point about 275 miles from the test site in the Fall, 1951, weapons tests in Nevada.

The Path of Carbon in Photosynthesis. XXI. The Cyclic Regenerationof Carbon Dioxide Acceptor

Description: Photosynthesizing plants have been exposed to C{sup 14}O{sub 2} for short periods of time (0.4 to 15 sec.) and the products of carbon dioxide reduction analyzed by paper chromatography and radio autography. Methods have been developed for the degradation of ribulose and sedoheptulose. These sugars, obtained as their phosphate esters from the above C{sup 14}O{sub 2} exposures and from other experiments, have been degraded and their distribution of radiocarbon determined. The distribution of radi… more

A Discussion of the Metallurgical Aspects of Thorium as a Fuel Material

Description: Data on thorium are compiled and the use of thorium as a fuel material is discussed. It was assumed that the general reactor configuration will follow the conventional SGR-SRE reactor design of a graphite-moderated sodium-cooled metallic fuel system. Factors outlined which affect the use of thorium as a fuel material are availability of ore, capacity of processing plants, purity specifications, design and use of materials in fuel elements which may affect chemical separation economics, and tech… more
