Spectrophotometric studies of solutions at elevated temperatures and pressures: status and program for FY1961 and part of FY 1962

Description: A program was initiated on the spectrophotometric study of aqueous solution chemistry. The goal is operation at temperatures up to at least 330 deg C and at pressures up to 200 atm, and to near the critical point if this appears to be feasible. A spectrometer capable of operation under these extreme conditions is being designed. (W.L.H.)

SM-1A PROJECT--TECHNICAL MANUAL: CHEMISTRY

Description: A manual is given of the equipment and procedures used in the Army Reactor (SM-1A) to control the water purity and makeup. In addition to a description of the primary purification control system, a discussion is presented of the water chemistry control procedures for the auxiliary systems (e.g., the spent-fuel pit, the shield tank, and the waste disposal system).

Phase Transformations in Alumina. Technical Report, May to December 1961

Description: e transformation studies showed that synthetic aluminas produced in the laboratory were not transformed to alpha alumina at 400 to 700' deg n the presence of nitric acid and water vapor. Amorphous aluminn produced in the pilot plant was transformed to alpha alumina. This indicated that the amorphous alumina produced in the pilot plant is structurally predisposed to form alpha alumina. Most additives did not appear to have any special effects. Lithium formed zeta alumina, LiAl/sub 5/O/sub 8/. Ph… more

Asymptotic Formula for Counting in Deterministic and Random Dynamical Systems

Description: The lattice point problem in dynamical systems investigates the distribution of certain objects with some length property in the space that the dynamics is defined. This problem in different contexts can be interpreted differently. In the context of symbolic dynamical systems, we are trying to investigate the growth of N(T), the number of finite words subject to a specific ergodic length T, as T tends to infinity. This problem has been investigated by Pollicott and Urbański to a great extent. W… more

Maritime Reactor Program Annual Progress Report for Period Ending November 30, 1961

Description: Progress is reported on general support of the NS Savannah, operation of the pressurized-water in-pile loop, and advanced core development. A shield survey, iodine adsorption studies, a bioassay development program, preparation of replacement control rod drives, irradiation testing of pressure-vessel steel, a thermal insulation investigation, and an analysis of primary system components for gamm-emitting elements were carried out in the NS Savannah program. Water- chemistry studies in the press… more

Chemical Equilibria and Reaction Rates for Hydrofluorination of UO$sub 2$ From "Ammonium Diuranate" and From UO$sub 3$

Description: Reaction rates for the hydrofluorination of UO/sub 2/ derived from two widely different source materials (sulfated pot-denitrated UO/sub 3/ and "ammonium diuranate," (ADU)) were determined in a thermobalance over a wide range of temperatures (460 deg F to 1150 deg F) and with several HF--H/sub 2/O gas phase mixtures varying from 20 to 100 per cent HF. These data were then organized to yield single plots for each type of feed material. From these plots, maximum instantaneous reaction rates may b… more

Steam Pressure-Reducing Station Safety and Energy Efficiency Improvement Project

Description: The Facilities and Operations (F&O) Directorate is sponsoring a continuous process improvement (CPI) program. Its purpose is to stimulate, promote, and sustain a culture of improvement throughout all levels of the organization. The CPI program ensures that a scientific and repeatable process exists for improving the delivery of F&O products and services in support of Oak Ridge National Laboratory (ORNL) Management Systems. Strategic objectives of the CPI program include achieving excell… more

Multiparameter Fiber Optic Sensing System for Monitoring Enhanced Geothermal Systems

Description: The goal of this project was to design, fabricate and test an optical fiber cable which supports multiple sensing modalities for measurements in the harsh environment of enhanced geothermal systems. To accomplish this task, optical fiber was tested at both high temperatures and strains for mechanical integrity, and in the presence of hydrogen for resistance to darkening. Both single mode (SM) and multimode (MM) commercially available optical fiber were identified and selected for the cable base… more

Performance Characteristics of an Extended Throat Flow Nozzle for the Measurement of High Void Fraction Multi-phase Flows

Description: An extended throat flow nozzle has been examined as a device for the measurement of very high void fraction (a ³ 0.95) multi-phase flows. Due to its greater density and partial contact with the wall, the equilibrium velocity of the liquid phase appreciably lags that of the lighter gas phase. The two phases are strongly coupled resulting in pressure drops across the contraction and in the extended throat that are significantly different than those experienced in single-phase flow. Information ab… more

Fuel Management in Large Pressurized Water Reactors

Description: Economic and operational ground rules and their effects on fuel management are summarized, and examples showing the approach to typical fuel management problems are presented. The problems associated with in-core fuel management are also discussed, and the merits of various fuel cycling methods are evaluated. (D.C.W.)

Thermal Study of Crystal Field Splittings in Erbium Ethylsulfate

Description: The heat capacities of erbium and yttrium ethylsulfates were measured in the range 12-300 deg K. The magnetic contribution of the erbium ion was evaluated with the help of an assumption concernlng the difference in lattice contributions between the erbium and yttrium salts. The contribution agrees, to within experimental error, with the experimental energy level scheme for the /sup 4/I/ sub 15/2/ state previously published. (auth)

Observations of Stresses and Strains Near Intersections of Conical and Cylindrical Shells

Description: To test theory, models of the interaction of a conical and cylindrical shell, having three different apex angles in the cone and three different ratios of thickness to cylinder diameter, were subjected to internal hydrostatic pressure and the resulting strains at various points were measured. Careful studies were made of the unavoidable imperfections in the models. The results are in substantiai agreement with the Wenk-Taylor approximate theory described in TMB Report 826 and with the approxima… more
