HEAD-END TREATMENT OF LOW LEVEL WASTES PRIOR TO FOAM SEPARATION

Description: Calcium-magnesium precipitation apparatus was used to reduce the concentrations of these elements in ORNL tap water, used as a substitute for waste water of low level of radioactivity, prior to strontium removal by foam separation. With and without alkali and flocculator chambers and with a stirred sludge of ratio height to diameter equal to 1/1 to ~4/1, use of 5 x 10/sup -3/ M each of NaOH and Na/sub 2/CO/sub 3/ and 2 ppm Fe/sup 3+/ reduced the dissolved Ca + Mg concentrations to 1 to 2 ppm as… more

LABORATORY PROGRESS ON THE DISPOSAL OF HIGH-LEVEL RADIOACTIVE WASTE BY DEEP- WELL INJECTION

Description: Results of laboratory studies on the neutralization of Purex-type wastes are reported, including the radiochemical distribution of the fission products in the precipitate and supernate and the effect of sodium and calcium neutralizations on fission-produet separation. The problem of interstitial precipitation encountered when a second incompatible liquid is injected into a formation is discussed. Results indicate a piston-iike displacement of the interstitial liquid by the injected waste with o… more

HOT CELL DEMONSTRATION OF ZIRFLEX AND SULFEX PROCESSES. Report No. 1

Description: Four runs were conducted in the Zirflex-Sulfex headend hot cell equipment. Prototype PWR blanket rods, Zircaloy2 clad UO/sub 2/, irradiated from 159 to 356 Mwd/t and decayed 2 years, were declad in boiling 6 M NH/sub 4/F-l M NH/sub 4/NO/sub 3/, terminating with a F/Zr mol ratio of 7 in the spent decladding solution. Average decladding time was 1.5 hr, leaving end cap residues of about 5 g per pin. At the end of the decladding, maximum loss of uranium and plutonium to the decladding solution was… more

Strontium, Strontium-90, and Calcium Analyses of Clinch and Tennessee River Clams

Description: Analyses of clam shells for Sr, Sr/sup 90/, and Ca are reported. The data include 208 Sr, 80 Sr/sup 90/, and 35 Ca analyses. Information on age of the clam and shell weight are also included because the Sr concentration in some shells is affected by age and growth rate. A detailed description of sample treatment and preparation is also included. (auth)

BIO-ORGANIC CHEMISTRY QUARTERLY REPORT. December 1961, January andFebruary 1962

Description: It has been known for a hundred years that formaldehyde polymerizes to carbohydrate substances in alkaline media. Although the reaction has long attracted much attention, only recently has a detailed qualitative analysis of the products been carried out by chromatographic methods. We have started to re-examine this reaction by combining chromatography with radioactive tracer techniques in the hope of refining the quantitative aspects of the analysis. Our particular interest has been to develop … more

PRODUCTION OF TRITIUM BY CONTAINED NUCLEAR EXPLOSIONS IN SALT: I. LABORATORY STUDIES OF ISOTOPIC EXCHANGE OF TRITIUM IN THE HYDROGEN-WATER SYSTEM

Description: The results of all exchange experiments suggest that tritium produced by a contained nuclear explosion wiil be mixed with environmental water. Tritium exchange in the reaction HTO + H/sub 2/ in equilibrium HT + H/sub 2/O was catalyzed at 600 deg C by a number of oxygenated salts that occur in salt formations. Calcium sulfate was the best catalyst, with values as high as 49 and 77% with pure CaSO/sub 4/ and Drierite, respectively. in deep bed tests. Even under diffusion-controlled conditions, wh… more

IRRADIATION TESTING OF CERAMIC FUELS. Summary Report

Description: S&gt;A research program was completed on the composition limits for single- phase face-centered cubic crystal structures in the ZrO/sub 2/-rich region of UO/ sub 2/-CaO-- ZrO/sub 2/ and in the CeO/sub 2/-rich end of UO/sub 2/-- CeO/sub 2/, on the fabrication of highdensity pellets from these cubic compositions of both systems, on the properties of these cubic compositions, and on the irradiation stability of these compositions. Phase studies are reported that confirm the occurrence of cubic reg… more

CERAMIC NUCLEAR FUELS IN THE SYSTEM ZrO$sub 2$-CaO-UO$sub 2$. Final Report

Description: Potential nuclear fuels in the system ZrO/sub 2/-CaO-UO/sub 2/ were investigated. Cubic fluorite-type solid solutions, as indicated by x-ray diffraction patterns, were formed by sintering CaO-stabilized ZrO/sub 2/ and U/ sub 3/O/sub 8/ compacts in either air or H/sub 2/. A continuous solid solution was found between urania and stabilized zirconia with H/sub 2/ sintering at 1750 deg C. Air sintering produced a limited region of solid solution in the stabilized zirconia portion of the system at 1… more

Electron Requirements of Bonds in Metal Borides

Description: From abstract: "Electrical measurements have been made on CaB6, SrB6, BaB6, YB2, YB4, YB6, and YB12 for the purpose of testing models of the electronic structure of the boron atoms in the four boride types represented. The compounds CaB6, SrB6, and BaB6 were found to be semiconductors. The Hall coefficients of YB4 was also measured, but could not be interpreted because the free electron theory does not provide a theoretical value for comparison with experiment. The results are in agreement with… more

Cation Exchange Separation of Divalent Metal Ions From Rare Earths

Description: From abstract: "The divalent metal ions of calcium, magnesium, nickel, and strontium are eluted from a cation exchange column with 1.5M nitric acid and separated from trivalent rare earths, aluminum and yttrium. Prior sequential elution of other metal ions with hydrochloric acid in acetone-water or with dilute hydrofluoric acid does not interfere with the present separation method."

TRANSFERENCE NUMBERS AND ION ASSOCIATION IN PURE FUSED ALKALINE EARTH CHLORIDES

Description: The transference number of the chloride ion was determined in pure fused MgCl/sub 2/, CaCl/sub 2/, SrCl/sub 2/, and BaCl/sub 2/ utili zing radioactive chloride ions in a porous quartz membrane cell. On the basis of a two-step dissociation for these salts, MCl/sub 2/ in equilibrium MCl/sup +/ + Cl/sup -/ in equilibrium Ml/sup +/ + 2Cl/sup -/, the ext ent of the second dissociation was qualitatively predicted from a consideration of the relative mobilities of the ions.
