RIA Scoping Test Experiment Specification Document

RIA Scoping Test Experiment Specification Document

Date: July 1, 1977
Creator: A. M. Eaton, Z. R. Martinson
Description: The experiment requirements and objectives for the reactivity initiated accident (RIA) tests to be conducted in the Power Burst Facility (PBF) are described 1n the RIA Experiment Requirements Document (ERD) The primary objectives of the RIA research are to determine fuel failure thresholds, modes and consequences as functions of enthalpy insertion, irradiation history, and fuel design. Coolant conditions of pressure, temperature, and flow rate that are typical of hot-startup conditions in commercial BWRs will be used in the Series 1 tests. The first R!A test outlined in the ERD, RIA 1-1, is to be performed using four test fuel rods (two unirradiated and two irradiated) in the four rod hardware. The test fuel rods are to be exposed to a power transient in PBF which deposits an anergy of about 300 cal/g at 90% of the fuel radius (i.e. near the fuel surface). This will be the first RIA experiment ever perfonned at hot startup conditions and three potential problems have been identified since the ERD was written. These problem areas are: identification of the fuel failure threshold energy deposition for hot-startup conditions, evaluation of calorimetry techniques for RIA transient tests, and determination of possible pressure pulses that can result ...

REPASSIVATION STUDIES OF ALUMINUM USING A ROTATING STRIP ELECTRODE

REPASSIVATION STUDIES OF ALUMINUM USING A ROTATING STRIP ELECTRODE

Date: September 1, 1977
Creator: ALDYKIEWICZ,A.J.,JR. & ISAACS,H.S.
Description: In this work a technique was described to study the repassivation of bare metal surfaces. The advantage of this approach over other techniques is the ease with which multiple repassivation events can be studied. The repassivation rate of aluminum was found to depend on the anion in solution. Repassivation rates are higher for aluminum in phosphate and sulfate solutions compared to borate. It is possible that borate may interact more strongly than sulfate or phosphate on the bare aluminum surface blocking the diffusion of oxygen or changing the rate of repassivation.

Date: September 1977
Creator: Addor, Eugene E.
Description: "During the growing season of 1975, a field experiment was initiated on Lake Concordia, Louisiana, to test the potential effectiveness of selected organisms as control agents against waterhyacinths, Eichhornia crassipes (Mart.) Solms. [...] This report describes the experiment, presents the collected data, and summarizes the observations. Statistical analyses and interpretation of the data are also presented" (abstract).

DAMAGE TO MITOCHONDRIAL ELECTRON TRANSPORT AND ENERGY COUPLING BY VISIBLE LIGHT

DAMAGE TO MITOCHONDRIAL ELECTRON TRANSPORT AND ENERGY COUPLING BY VISIBLE LIGHT

Date: September 1, 1977
Creator: Aggarwal, B.B.; Quintanilha, A.T.; Cammack, R. & Packer, L.
Description: Plutonium is one of the principal materials of both commercial and military nuclear power. It is produced primarily in fission reactors that contain uranium fuel, and its importance arises from the fact that a large portion of the plutonium produced is fissile: like uranium 235, the mass 239 and 241 isotopes of plutonium can be caused to fission by neutrons, including those with low energy. Because such fission events also release neutrons, substantial amounts of energy can be extracted from plutonium in a controlled or an explosive nuclear chain reaction. Now that commercial nuclear reactors provide a noticeable fraction of United States (and world) electrical energy, these reactors account for most plutonium production. For the most part, this material now remains in the irradiated fuel after removal from reactors, but should this fuel be reprocessed, the plutonium could be recycled to provide part and even most of the fissile content of fresh fuel. For the current generation of water-cooled reactors, the amount of plutonium to be recycled is substantial. In fast breeder reactors, designed to produce more fissile material than they destroy, considerably larger quantities of plutonium would be recycled. In other types of advanced reactors, particularly those which depend ...

Development and Demonstration of Compound Parabolic Concentrators for Solar Thermal Power Generation and Heating and Cooling Applications, Progress Report: July-December 1975

Development and Demonstration of Compound Parabolic Concentrators for Solar Thermal Power Generation and Heating and Cooling Applications, Progress Report: July-December 1975

Date: 1977
Creator: Allen, John W.; Levitz, Norman M.; Rabl, Ari; Reed, Kent A.; Schertz, William W.; Thodos, George et al.
Description: Progress report describing the development of Compound Parabolic Concentrators (CPC). A tenfold concentrator with a cavity receiver was constructed and tested. The optical efficiency was very good (65 percent), but the thermal performance was degraded by heat losses of the cavity receiver. A summary of the results of subcontracts described in the previous progress report are presented, and the influence of these results on ANL programs is noted.

SYNTHESIS AND CRYSTAL STRUCTURE OF A NEODYMIUM ISOPROPOXIDE CHLORIDE, Nd6[OCH(CH3)2]17Cl1

SYNTHESIS AND CRYSTAL STRUCTURE OF A NEODYMIUM ISOPROPOXIDE CHLORIDE, Nd6[OCH(CH3)2]17Cl1

Date: December 1, 1977
Creator: Andersen, R.A.; Templeton, D.H. & Zalkin, A.
Description: Neodymium (III) chloride reacts with sodium isopropoxide in isopropyl alcohol to produce a complex which has been characterized by an x-ray crystal structure determination to be hexa-isopropoxy-nona({mu}{sub 2}-isopropoxy)-di-({mu}{sub 3}-isopropoxY)-({mu}{sub 6}-chloro-hexa-neodymium), Nd{sub 6}[OCH(CH{sub 3}){sub 2}]{sub 17}Cl. The pale blue crystals are monoclinic, space group P2{sub 1}/n with cell dimensions a = 24.52(2) {angstrom}, b = 22.60(2) {angstrom}, c = 14.22(1) {angstrom}, and {beta} = 101.05(5){sup o}; for four molecules in the unit cell the calculated density is 1.636 gm/cc. The structure was refined by full-matrix least-squares to a conventional R factor of 0.076 for 2327 data with I > 2{sigma}. The six neodymium atoms form a trigonal prism centered about the chloride atom. Six isopropoxide groups are terminal, nine are edge bridging, and two are bridging a trigonal face of the prism yielding six two-coordinate, nine three-coordinate, and two four-coordinate oxygen atoms, respectively. The average Nd-Cl distance is 3.05(1) {angstrom}. The average Nd-O distances for oxygen atoms which are bonded to one, two, and three Nd atoms are 2.05(2) {angstrom}, 2.36(4) {angstrom}, and 2.45(5) {angstrom}, respectively.
