I. Niobium(IV) Bromide and Pyridine Adducts of the Niobium(IV) Halides

Description: Technical report. From Abstract : "Reaction of NbBr5 and niobium metal in a sealed tube under a temperature gradient from 410° to 350° gave NbBr4 in good yields. However, an increase in the higher temperature from 410° to 450° was sufficient to eliminate NbBr4 as a product and cause deposition of a lower bromide."

Electrical Resistivity of Rare-Earth Alloys

Description: From abstract: "Resistivities of solid solution alloys in the systems Gd-Lu, Tb-Lu, Gd-Er, and Y-Lu were measured from 4.2-320°K to determine the behavior of the resistivity in alloy systems with magnetic phenomena arising from localized magnetic moments. A large contribution to the residual resistivity is caused by the random distribution of these localized moments through the lattice. An analysis of the lattice resistivity of the metals shows large variations across the heavy rare-earth serie… more

Analysis of Zero Power Experiments on SM-1 Core II and SM-1A Core I

Description: Abstract: An analysis of SM-1 Core II and SM-1A Core I zero power experiments was made by comparing these cores to each other and to AM-1 Core I on the basis of critical bank positions, bank calibrations and available chemical analyses of the fuel plate compositions. The effects of replacing boron absorbers by europium absorbers upon rod worth and stuck rod conditions were studied. Comparisons of measured and calculated power distributions were made. It was concluded that both SM-1 Core II an… more

Periodic Radiation Survey. Section II. First Performance. Test Results DL-S-231, T-612394

Description: The purpose of the test was to determine the radiation level in the Turbine-Governor Service Building, around the Fuel Handling Canal and in the limited access areas of the reactor plant containers during plant operation. All radiation levels were background level readings except for a few points above background located in the walkway areas going from the auxiliary chamber into the reactor chamber, boiler chamber and pressurizer compartment. The only neutrons detected were slow neutrons in th… more

Radiation Stability of Organic Liquids. Semi-Annual Report No. 4 for 1 July to 31 December 1958

Description: When most solvents are exposed to radiation, decomposition occurs. The decomposition products may adversely affect the solvent extraction of uranium, thorium, or plutonium in a variety of ways. The current study is concerned with (1) evaluation and examination of new and more efficient methods for economic removal deleterious radiolysis products from irradiated extractant systems., (2) methods of reducing the amount of radiolytic damage by use of additives which exert a protective effect on the… more

Effect of Reflectors on Resonance Escape Probability

Description: Some procedures now being used for burnup calculations make use of a neutron balance equation as a criticality relation for exploring reactivity during reactor life. This balance makes use of a resonance escape probability calculated for the core composition as an infinite medium as the effective resonance escape probability.
