Use of Discharge Tubes in Spectrochemical Analysis

Description: While this survey of discharge tube sources probably has not yielded information of much direct interest to the great majority of analysts, it seems probable that these sources will become of greater interest as they become better developed and more demand is created for extension of spectrochemical methods to non-metallic samples.

Flow Distribution Across the Core. Test Results DL-S-182 (T-550097). Section II

Description: The purpose of the test was to determine the flow mixing characteristics of the lower plenum. Conclusion: Mixing appears to be quite small. The temperature indicated by the thermocouple nearest the cold loop decreased approximately 15 F. The cold loop temperature was 15 below the initial reactor coolant average temperature when the cold loop was places in services. The thermocouple furthest from the cold loop showed little or no change in temperature. The rate of change of reactor coolant tempe… more

The Design of a Nuclear Coolant Pump Speed Sensor

Description: "The design utilizes a 12-pole rotor with poles of magnetic 410 stainless steel. A voltage, the frequency of which is proportional to pump speed, is generated by a coil wound on a magnetized core. The coil is inserted in a well similar to that used for thermocouples. No penetration by electrical wires of the pump seal is required, and the coil can be readily replaced."

Thermal Cycle Test in Sodium of an APDA Fuel Pin

Description: "An investigation was undertaken to determine the effect of thermal cycling in sodium of various fuel pins. The pin submitted for this test was a depleted uranium--10 wt.% molybdenum fuel pin sheathed with sponge zirconium, commercial grade. The pin was not end capped. The test consisted of the following thermal cycle: heating to 1575 plus or minus 25 deg F, holding, cooling to 250 plus or minus 25 deg F. The temperature of the test specimen exceeded 12OO deg F for at least 30 min. for each cyc… more

Test Results, Determination of the Chemical Characteristics of the 1B Boiler

Description: "The chemical characteristics of the 1B boiler under variable load conditions were determined in order to ascertain what factors might have contributed to the heat exchanger tube failures. Chemical tests performed on the 1B boiler indicated that boiler water concentrations differed appreciably at various locations within the unit under high load conditions. Discrepancies were noted in the chemical concentrations in samples collected from two neighboring regions in the heat exchanger. The signif… more

Dynamic B and n-Behavior Up to 7600 Gauss in Magnet Model Mark Ii Comparison of Results With Long and Small Grad Coils

Description: "Magnetic measurements were performance at excitation levels ranging from 4000 to 7600 gauss, to study the dynamic behavior of the magnetic and gradient lengths of the CEA magnet sectors. The influence of the proposed metal vacuum chamber on field and gradient was experimentally determined. Results of measurements made with a 26 in. long grad coil and with small circular grad coils are compared. The reliability of the 26 in. long grad coil is demonstrated."

Path of Triple Point for spherical Shocks Above a Rigid Plane

Description: Paths of trip points of Mach reflections produced by 0.5-oz pentolite detonations have been observed for various burst heights. The slopes, Y, at points on the curved path are found to vary from values of Y predicted from plane shock wave data. This discrepancy is attributed to the shock strength conditions at the early inception of the Mach reflection, which later influence the triple point equilibrium, and in lesser degree to radius of curvature effects.

Effects of Ionizing Radiations (And Other Agents) on the Developing Mammal

Description: We have been administering various forms of metabolic inhibition to adult, newborn and pregnant animals and studying them pathologically. The purpose of this program was threefold: (1) to learn how various tissues, especially parts of the nervous system, differ from one another metabolically and how they will therefore respond differently to the agents; (2) to learn in a similar way how embryonic tissues differ among themselves from the adults, and how their metabolism changes during developmen… more

Operation of 1/4 Scale Model Bevatron

Description: Accelerated protons were first observed in the 1/4 Scale Bevatron on April 30, 1949. This is an account of some of the things learned since then. The results are still meager and must be considered provisional.

Stratospheric Monitoring Program

Description: "Design work was completed and construction initiated on a prototype field altimeter based on the gas density dependence of Townsend discharge current in an electrical discharge. The design of an ion tracer air velocity meter for laboratory applications, and construction of three units were successfully completed. Theoretical and experimental support is presented, showing the applicability of the ion tracer system to the accurate measurement of linear gas velocity. The operating range of the la… more

Strontium an Calcium Metabolism in Man, Final Report

Description: "During the first two years of this program the investigation centered around the distribution of strontium and calcium in tissues of persons who came to autopsy who had received a single tracer dose of Sr85 and Ca45. I then seemed desirable to attack some of the more dynamic aspects of strontium and calcium metabolism."
