Alpha Particle Ionization of Argon Mixtures--Further Study of the Role of Excited States

Description: BS>The average energy required to form an ion pair, W, when alpha particles are absorbed in mixtures of argon with other gases is studied. The other gases were selected on the basis of their ionization potentials. One group consists of representative gases that have ionization potentials below that of Ar (15.77 ev) and above the doublet metastable state of Ar (11.49 and 11.66 ev). This list includes methane, carbon dioxide, nitrous oxide, xenon, and krypton. The other group of special interest … more

Comparison of Dialkyl Phenylphosphonates With Tri-N-Butyl Phosphate in Nitrate Systems: Extraction Properties, Stability, and Effect of Diluent on the Recovery of Uranium and Thorium From Spent Fuels

Description: Di-n-butyl phenylphosphonate (DBPP) and di-sec-butyl phenylphosphonate (DSBPP) were investigated as possible substitutes for tri-n-butyl phosphate (TBP), the reagent presently employed in the reprocessing of uranium and thorium nuclear reactor fuels. The phenylphosphonates form complexes with uranium and thorium that are mostly insoluble in the aliphatic solvents commonly used as diluerts for TBP but that are soluble in other diluert type, for example, aromatics and CCl/sub 4/. Therefore, the p… more

CONTINUOUS DISSOLUTION OF ZIRCONIUM REACTOR FUELS IN TITANIUM EQUIPMENT: LABORATORY DEMONSTRATION

Description: Continuous dissolution of 2% U-- Zr alloy fuel in a laboratory-scale Ti dissolver was demonstrated using refluxing 3 M HNO/sub 3/--1.2 M HF--0.4 M HBF/ sub 4/--0.6 M Cr(III)0.4 M Cr(VI)--0.46 M Zr as the dissolvent. Dissolution rates and solution corrosion rates were 8 to 16 mg/cm/sup 2/min and approximates 1 mil/month, respectively. Reagent was added to the dissolver at the rate needed to maintain the potential measured by a Au vs. calomel electrode in the product effluent as close to a presel… more

Demonstration of the Zirflex and Sulfex Decladding Processes and a Modified Purex Solvent Extraction Process, Using Irradiated Zircaloy-2 and Stainless-Steel-Clad Urania Specimens

Description: The Zirflex and Sulfex processes for chemical decladding Zircaloy or stainless-steel-clad UO/sub 2/ power reactor fuels were successfully demonstrated at irradiation levels as high as 28,200 Mwd/t. The Zircaloy jackets were dissolved in boiling 6 M NH/sub 4/F-- 1 M NH/sub 4/NO/sub 3/, and the stainless steel jackets were dissolved in refluxing 4 M H/sub 2/SO/sub 4/. Both processes gave average soluble losses of uranium and plutonium to the decladding reagents of about 0.05%. Centrifugation or f… more

Dynamic Calibration Study

Description: Since transducers used in rocket engine applications measure time varying quantities, the characteristics which define the behavior of a transducer under dynamic conditions are extremely important in their applications by the design engineer. Proper calibration of transducers in the dynamic or frequency domain required a thorough understanding of the dynamic or frequency domain required a thorough understanding of the dynamic characteristics of a transducer. Analytical models are generated in h… more

The Effect of Cl$sup -$ and So$sub 4$$sup -2$ on the Paramagnetic Resonance Line Width of Mn$sup +2$ in Aqueous Solution and the Rates of Formation of the Complex Ions

Description: The line width of one of the hynerfine components in solutions of Mn(ClO/ sub 4/)/sub 2/ containing added NaCl and Na/sub 2/SO/sub 4/ was studied from 20 to 200 deg C at 9000 Mc/sec. The chloride ion contributes littie broadening at 0.1 M below 80 deg C but considerable broadening is obtained above this temperature. The sulfate contributes broadening at all temperatures. The rates of formation of inner-sphere'' and outersphere'' complexes are discussed together with their rates of relaxation. A… more

Effect of Low Compressive Stresses on Radiation-Induced Dimensional Changes in Graphite

Description: Samples of five nuclear-grade graphites were irradiated under constant compressive stresses of 150 and 300 psi. Length changes of the stressed samples are compared with length changes of unstressed control samples, irradiated in the same assembly. Results obtained at 825 deg C and for exposures up to 6500 Mwd/ at. in a Hanford irradiation facility are presented. Additional data on one nuclear-grade graphite, irradiated under 100 psi constant tensile stress, are included. (auth)

Increased coolant flow for H reactor

Description: The purpose of this letter is to outline the immediate and long-range plans for increasing the H Reactor coolant flow. The flow can be increased, immediately from the present base of about 84,000 gpm to about 88,000 gpm via the following changes: routine purges; use of non-bumpered fuel; increasing the flow through Fringe enrichment and Fringe Poison tubes by changing orifices; and reaming damaged rear fittings to their original size. The flow can be increased to about 94,000 gpm via the follow… more

Ion Exchange Absorption of Cesium by Potassium Hexacyanocobalt(II) Ferrate(II)

Description: Abstract: A description is given of the preparation and properties of a granular form of potassium hexacyanocobalt (II) ferrate (II) that is a highly selective absorbent for cesium ion. The material is suitable for use in a large-scale ion exchange column, and offers the possibility of isolating and concentrating Cs137 from fission product waste solutions that arise from the processing of nuclear fuels.

LONGITUDINAL RESISTIVE INSTABILITIES OF INTENSE COASTING BEAMS IN PARTICLE ACCELERATORS

Description: The longitudinal electromagnetic interaction of an intense coasting beam with itself, including the effect of a resistive vacuum tank, is investigated theoretically. It is shown that even in the range where the particle frequency is an increasing function of particle energy, the beam can be longitudinally unstable due to the resistivity of the vacuum tank walls. In the absence of frequency spread in the unperturbed beam the beam is shown to be always unstable against longitudinal bunching with … more
