Prescoping Optimization for Selection of Enriched Uranium Gas-Cooled Power Reactor Design

Description: A preliminary set of performance calculations were made for enriched reactor cores based on five cylindrical vessel designs ranging from13 to 36 feet in diameter. The capital costs per kilowatt of electrical plant output as shown in Table II indicate than an economic optimum selection of pressure vessel size should be either the 25 foot or the 36 foot vessel.

Increase in reactor power ratings through increased H{sub 2}O and D{sub 2}O flow rates

Description: As a part of the Productivity Increase Program, consideration should be given to further gains in 100 Area production levels which can be achieved by further increases in both light and heavy water flow rates. This memorandum presents a summary of the power level gains which should be achieved from the flow increases under consideration, a discussion of the costs and production losses which might apply, and a brief listing of some other considerations which might influence any decision to incre… more

HAPO irradiation of capsules containing UO{sub 2} specimens

Description: A knowledge of the effect of reactor irradiation on the properties of UO{sub 2} is relevant to the design and evaluation of UO{sub 2} fuel elements for the PRTR. Of particular interest is the effect of reactor irradiation on the thermal conductivity of sintered UO{sub 2} and the type, mechanism, and extent of radiation damage in sintered UO{sub 2}. In the latter case the study of fractured surfaces of irradiated UO{sub 2} specimens is a method of determining the extent of radiation damage. It i… more

Fluidization in Tapered Beds

Description: Abstract: The concept of a tapered fluidized bed is explored briefly. Data are given showing that in bench scale apparatus a tapered bed gives better fluidization with some materials that are difficult to fluidize in a conventional cylindrical bed.

Air-Gun Studies of Ferroelectric Materials (Second Printing)

Description: Specimens of two ferroelectric materials, barium titanate and lead-zirconate titanate, have been subjected to high dynamic stresses by impacting them with a projectile accelerated by an air gun. The purpose of these tests was to supplement information previously obtained using high explosives to stress the ferromagnetic materials.

Water Hammer Tests Loop Able Pwp Land Reactor, 1957

Description: "This report essentially substantiates the preliminary data reported ln WAPD-PWR-PMF-898. The Primary Coolant System of the Pressurized Water Reactor (PWR) at Shippingport, Pennsylvania, comprises four loops. Each of the loops has one pump to control the mass rate of water flow-. A series of tests were conducted on the cooling system of the PWR land reactor to determine the magnitude and duration of the water hammer pressure wave resulting from check valve closure. The water hammer pressure wav… more

Qualitative Simulator Study of Longitudinal Stick Forces and Displacements Desirable During Tracking

Description: In this study in which an airplane simulator with one degree of freedom (pitch) was used, results were determined for three conditions of airplane dynamics. For an undamped natural frequency of 1/2 cps with a damping ratio of 0.18 and for an undamped natural frequency of 1 cps with a damping ratio of 0.11, moderate longitudinal stick forces and displacements were desired.

Flight Investigation of Effects of Atmospheric Turbulence and Moderate Maneuvers on Bending and Torsional Moments Encountered by a Helicopter Rotor Blade

Description: Note presenting flight tests conducted with a medium-size single-rotor helicopter, of which one blade was equipped with strain gages, to determine the relative effects of atmospheric turbulence and moderate maneuvers on the periodic rotor blade moments. The results indicate no significant increase in the total blade moments due to atmospheric turbulence of moderate pull-up maneuvers which produced center-of-gravity acceleration increments of less than about 0.15g. Results regarding moment recor… more

Temperature-Pressure-Time Relations in a Closed Cryogenic Container

Description: Note presenting an experimental study using liquid nitrogen made to verify the existence of a temperature gradient as the factor causing the increase in pressure and to investigate the effect on pressure of altering the temperature gradient. The effect on pressure of different heat-leak rates into the container and different quantities of liquid was also investigated. Results regarding the typical pressure history and temperature gradient, effect of stirring liquid on pressure, effect of heat-l… more

Charts Relating the Compressive and Shear Buckling Stresses of Longitudinally Supported Plates to the Effective Deflectional Stiffness

Description: "A stability analysis is made of long flat rectangular plates subjected to both shear and compressive loads. The edges of the plates are taken to be simply supported and the plates are supported along one or two intermediate longitudinal lines by lines of deflectional springs (elastic line supports). The results of the analysis are presented in the form of charts that are useful in the determination of the buckling load of plates stiffened by stringers or webs" (p. 1).
