Betatron Oscillation Frequency Shift Due To "N-Errors"

Description: "Expressions are found to relate DELTA gamma to the n-errors.'' It is demonstrated that the integral n-value concept'' is of no use in the present case. A modification of integrated n-value'' is suggested."

Preparation, Cladding, and Evaluation of Titanium-Boron Dispersions

Description: Powder dispersions of titanium--boron and titanium-boron carbide were prepared, clad, and evaluated for use as control materials. Compacts possessing up to 95 per cent of theoretical density were prepared by a hot-pressing technique. The relatively low temperatare of 1500 deg F was used to obtain the desired high density. There was no visible reaction between the boron dispersant and titanium. Excellent metallurgical cladding of the titanium-- boron dispersion with titanium was achieved by the … more

Low Cross-Section Iron-Base Alloys

Description: Data are presented on the mechanical properties of iron-silicon and iron- aluminum alloys in the range 0 to 14% Si and about 8% aluminum. The effect of third elements on ductility is discussed, and data are prcsented which indicate that it is not possible to obtain a disordered structure in Fe--Si a1loys from 8 to 14% Si. It is concluded that alloys of iron with 6 to 8% aluminum offer a promising base composition for development of low neutron cross section alloys for use in nuclear reactors. (… more

THE ECONOMICS AND HAZARD POTENTIAL OF WASTE DISPOSAL

Description: The two most important considerations in the disposal of radioactive wastes are safety and economy. All other steps in the waste disposal complex must be tuned to accomplish these two goals. In general, the hazardous waste in the nuclear power complex affect the cost of the nuclear power reactor fuel cycle, the general environment since disposal must exclude radioactivity from the environment for over 500 years, the costs and/or methods of waste treatment including fission product utilization, … more

AN ALPHA COUNTER FOR UNIFORMITY MEASUREMENTS

Description: An ionization-type alpha counter is used to mensure the uniformity of thin coatings of alpha -emitting materials to plus or minus l% exclusive of statistical error. The (n, alpha ) reaction allows the counter to be used for measuring the uniformity of B/sup 10/ foils when a suitable neutron source is provided. (auth)

Single-Fluid Two-Region Aqueous Homogeneous Reactor Power Plant Conceptual Design and Feasibility Study. Final Report

Description: The feasibility of a 150 Mwe aqueous homogeneous nuclear power plant was investigated by a joint study team of the Nuclear Power Group and The Babcock & Wilcox Company. In this concept, the reactor is a single-fluid two-region design in which the fuel solution circulates through the thoria pellet blanket as the coolant. Componeats and plant arrangement were designed to provide maximum overhead accessibility for maintenance. All components in contact with reactor fuel at high pressure are themse… more

Three Channel Alpha Fission Counter

Description: Two parallel-plate fi ssion counters, utilizing U/sup 235/ foils, amd a parallel-plate alpha counter, utilizing a B/sup 10/ foil, are combined in one chamber for cross-section measurements at low neutron energies. The alpha counter allows a l/V normalization of the neutron beam intensity. (auth)

REACTIVITY STUDIES OF URANIUM OXIDES

Description: One amorphous and three crystalline polymorphic modlfications of UO/sub 3/ have been prepared by pyrolysis of uranyl nitrate hexahydrate. The hydration reactivity of UO/sub 3/ appears to be a function of its residual N content which is, in turn, dependent on the method, time, and temperatuee of denitration. Amorphous UO/sub 3/ is more reactive than crystalline UO/sub 3/. The initial oxidation reactivity (the O/sub 2/ sorption in 1 day at room temperature) of UO/ sub 2/ varies with the method of… more

The Fast Oxide Breeder-the Fuel Cycle

Description: The development of a fast breeder fuel cycle based on a core fuel consisting of mixed dioxides of uranium and plutonium is described. Process flowsheets, material balances, operating schedules, cost schedules, and a plant layout are presented, and the laboratory- and plant-scale process and equipment demonstrations are described. A cost estimate based on a demonstration of the process including the unique plant equipment gives a total fuel cycle cost of 2.04 mils/kw-hr and a net fuel cycle cost… more

The Effect of D20 on Survival of Mice with Ascites Tumor

Description: The effect of deuterium oxide (D{sub 2}O) on the survival of mice inoculated with Ehrlich's mouse ascites tumor has been studied. Mice maintained on 25% and 30% D{sub 2}O drinking water showed an improved survival time of about 6 days whereas 40% D{sub 2}O drinking water had no effect on survival time. The effect is interpreted in terms of inhibition of tumor cell division and systemic toxicity.

The Luminescence of Chlorophyll-Containing Plant Material

Description: The luminescence of various chlorophyll-containing plant materials has been investigated under a variety of conditions. The results have been shown to be consistent with a mechanism involving the recombination of electrons and holes trapped in a quasi-crystalline lattice. Some details of such a mechanism have been proposed which suggest the mode of entry of the light energy into the photosynthetic pathway.
