THE ADVANCED TEST REACTOR-ATR FINAL CONCEPTUAL DESIGN

Description: The results of a study are presented which provided additional experimental-loop irradiation space for the AECDRD testing program. It was a premise that the experiments allocated to this reactor were those which could not be accommodated in the MTR, ETR, or in existing commercial test reactors. To accomplish the design objectives called for a reactor producing perturbed neutron fluxes exceeding 1O/sup 15/ thermal n/cm/sup 2/-sec and 1.5 x 1O/sup 15/ epithermal n/cm/sup 2/-sec. To accommodate th… more

CALCULATION OF HETEROGENEITY EFFECTS IN ZPR-III FAST ASSEMBLIES USING THE DSN PROGRAM

Description: Reactivity changes, flux variations, and detector-response variations for ZPR-III fast critical assemblies, due to variations in heterogeneities caused by various intradrawer configurations of fuel and diluent plates and deviations of reactivities from ideal homogeneous cores, are calculated as reflective boundary slab cells using the DSN code. For these cells the calculated multiplication constants, for a given assembly plate configuration, by N = 4,8, and 16 approximations successively increa… more

The Effect of the Liquid Viscosity in Two-Phase, Two-Component Flow

Description: An evaluation was made of the effect of the liquid-phase viscosity on slip ratio using a forced-circulation two-phase two-component system operating at atmospheric pressure for air and glycerol-water mixtures. The effect of liquidphase viscosity on pressure drop was observed, and the flow regimes were identified and studied. The approximate ranges of the variables investigated were: liquid viscosity, 0.75 to 500 cp; quality, 0.005 to 0.0184; liquid flow rate, 0.2 to 0.8 Ib/sec; air flow rate. 0… more

Equilibrium Distribution Studies of Dysprosium Nitrate-Erbium Nitrate- Nitric Acid-Tributyl Phosphate Systems

Description: Separate equilibrium data were obtained for the distribution of Dy(NO/ sub 3/)/sub 3/- HNO/sub 3/, Er(NO/sub 3/)/sub 3/- HNO/sub 3/, and Dy(NO/sub 3/)< i3>iEr(NO/sub 3/)/sub 3/-HNO/sub 3/ systems between water and tributyl phosphate. Equilibrium data for the Dy(NO/sub 3/)/sub 3/- HNO/sub 3/ and Er(NO/sub 3/)/sub 3/ -HNO/sub 3/ systems were correlated in such a manner that the total distribution of solutes and nitric acid could be found for the Dy(NO/sub 3/)/sub 3/- Er(NO/sub 3/)/sub 3/- HNO/sub… more

Equilibrium of the System Lanthanum Nitrate-Praseodymium Nitrate-Nitric Acid-Water-Tributyl Phosphate

Description: A study of the extraction characteristics of the three systems lanthanum nitrate--nitric acid--water--tributyl phosphate, praseodymium nitrate--nitric acid--water--tributyl phosphate, and lanthanum nitrate--praseodymium nitrate nitric acid -water--tributyl phosphate was conducted. The separation factors between praseodymium and lanthanum for the system lanthanum nitrate--praseodymium nitrate-nitric acid--water--tributyl phosphate were shown to be a function of the total nitrate concentration of… more

Experiments on the Absorption of Polarized Negative MU Mesons by C12

Description: "This report describes two experiments performed in an effort to supply evidence for the universality of the V-A theory in weak interactions and for the law of conservation of leptons. In this first part the production rate of B to the 12th by the absorption of negative mu mesons in carbon was measured. From the amplitudes of the muon decay curve and the boron decay curve the rate was calculated to be (5.8 plus or minus 1.3) x 10 to the 3rd sec -1, in agreement with the hypothesis of a univers… more

The Fission Energetics of Th$Sup 23$$Sup 2$

Description: The distribution of the kinetic energy of fragments emitted as a result of the neutron-induced fission of Th/sup 232/ has been determined. Incident neutron energies of 1475 plus or minus 35 kev and l600 plus or minus 35 kev were used. The distributions determined at the two incident neutron energies are identical. The measured total average fragment kinetic energy was l55 plus or minus 4.5 Mev. The most probable fragment mass ratio is 1.47 plus or minus 0.05, and the average kinetic energies of… more

Laboratory Investigation of Decontaminating Solutions for Primary Loop Decontamination in the New Production Reactor

Description: An investigation was made of methods for decontaminating the primary loop of the New Production Reactor (NPR). Decontamination factors ranging from fifty to several thousand were obtained with several different combinations of cleaning solutions. In general, fission product activity was removed to a lower residual level than was activated corrosion product activity, and carbon steel was easier to decontaminate than was stainless steel. It was necessary to completely remove the oxide film from t… more

Mass Transfer Coefficients and Interfacial Area in a One Stage Pulse Column

Description: Over-all mass transfer coefficients were determined independently of the interfacial area by considering the operation of the pulse column to be a stage- wise process. The calculated coefficients describe only the operation of the pulse column for the free rise of organic droplets through a stage, since in the downstroke the aqueous phase passes through the organic phase in the form of rivulets preferentially wetting the plates. The driving force for transfer was based on the aqueous phase conc… more

Microwave Measurements of Hall Mobilities in Semiconductors

Description: From abstract: "The Hall mobilities of germanium single crystals were measured with a microwave frequence of 9000 Mc/sec over the temperature range 30°K to 300°K. A rectangular sample occupied the central part of the wall of a rectangular cavity, which was doubly generate in the TE101 mode and in the TE011 mode at a single resonance microwave frequency. The external magnetic field and microwave field associated with one of the two modes gave rise to the other mode of oscillation, owing to excit… more

The "Near" Magnetic Induction Signal from a Nuclear Explosion Due to Movement of the Earth's Magnetic Field

Description: The "near" magnetic induction signal from a nuclear explosion in the earth's atmosphere due to movement of the earth's magnetic field is predicated upon the entrapment of the earth's magnetic flux in the air surrounding the bomb. The entrapment of the flux is due to the initial conductivity of the ionization created by gamma rays. The subsequent movement of the magnetic flux is determined by the hydrodynamics of the expanding fireball so that a spherical hole is blown in the magnetic field dist… more

Operating Control Rods for the Enrico Fermi Atomic Power Plant. Final Design Report

Description: The final design of the operating control rods for the Enrico Fermi Atomic Power Plant was completed. Two such rods are located near the center of the reactor, which is sodium cooled. Boron carbide is used as poison material. A flow distribution test and analysis, thermal analysis, and stress analysis of the rod were performed for both the normal operating and scram conditions. The test and analysis show that the design meets APDA specifications. (auth)
