Adaptation of the Siemens Diffractometer for Precision Lattice Parameter Determinations of Single Crystals

Description: Modifications to the A.A.E.C.'s Siemens Diffractometer are described which enable precision lattice parameter determinations on single crystals. Analysis of the errors and consideration of results suggest that accuracies of about 1--2 parts in 10/sup 5/ are obtained on small beryllium oxide crystals. Details of alignment and measurement procedure are included.

An Analytical Model for Fission-Product Transport and Deposition From Gas Streams

Description: An important mechanism in the transport and deposition of very small particles from gas streams to the surfaces of a conduit is diffusion due to the Brownian movement of particles. The heat-mass analogy is used to describe the diffusion, and equations are derived for the deposition of fission products from a gas stream to wall surfaces as a function of the distance along the conduit. Effects of radioactive decay on the validity of the heat-mass analogy in applying standard heat transfer relatio… more

Beam Extraction From the MURA 50 Mev FFAG Accelerator

Description: The components, operation, and performance of the beam extraction system are described, and the selection and proporties of particle orbits in the extraction channel are discussed. Single accelerated beam pulses were observed to last 37 nsec, and 40 mamp per pulse currents were measured in the extracted beam. The 45-Mev stacked beam was also extracted in a single turn from the 50- Mev electron accelerator. (D.C.W.)

CALCULATIONS OF YIELDS OF PRODUCTS IN HIGH-FLUX NEUTRON IRRADIATIONS OF HEAVY ELEMENT SAMPLES

Description: Calculations have been made of the build-up of higher nuclides in samples of various heavy-element starting materials, at neutron fluxes ranging from 4 x 10/sup 13/ to 1 x 10/sup 16/ n/ cm/sup 2//sec, including the flux expected from the HFIR reactor at Oak Ridge (namely, 5 x 10/sup 15/ n/cm/sup 2// sec). Attempts have been made to estimate yields of the heavier fermium isotopes and of Md/sup 259/ by means of the nuclear properties predicted from systematics. The results indicate that it may be… more

Computer Generation and Testing of Random Numbers

Description: The need for random numbers, particularly in regard to Monte Carlo applications, andd the multiplicative mixed congruential methods most commonly used to obtain random numbers are discussed. Both methods involve somewhat arbitrary parameters. Proofs for the lengths of period for both methods and a derivation of an expression for the serial correlation coefficient in terms of the parameters of the mixed congruential method are presented. The results of a series of statistical tests made to deter… more

Demonstration Shipment of a Simulated Reactor by Rail. Volume II Data Analysis

Description: This report covers the round-trip demonstration shipment of an instrtumented NRX-A reactor from Large, Pennsylvania, to Las Vegas, Nevada. The major goal of this demonstration was to gather data relative to shipping loads. In an overview sense, it can be said that the demonstration showed that transportation environment and maximum acceleration loads are well within the requirements established by the reactor design criteria.

Determination of Actinides in Urine by Liquid Ion Exchange

Description: A liquid ion exchange method is described for the separation of the alpha -emitting actinides, Th, Np, U, Pu, Am, and Cm from urine preparatory to radionmetric analysis. Anion and cation reactions used to separate the actinides are described. (C.H.)

Effect of Neutron Irradiation on Materials Subjected to Multiaxial Stress Distributions. Quarterly Progress Report, April 1-June 30, 1963

Description: Results are reported for tensile and notched tensile tests on unirradiated and irradiated A-302B steel. The tensile results indicate that neutron irradiation decreases the uniform strain, increases the yield point, and decreases the strain hardening. The notched tensile results showed an increase in the ultimate tensile strength with irradiation. (D.L.C.)

Fast Neutron Flux in a Mockup of SM-1A Core and Vessel

Description: Flux measurements were made in a cold (68 deg F) mockup of the SM-1A reactor core, thermal shields, and pressure vessel. Neutron flux distributions were mapped in radial and axial directions by means of detector foils to cover thermal, resonance, and fast neutron energy ranges. Multigroup calculations were also made for this cold mockup, using the P1MG-2 and PDQ (rz)/-2 codes. These results were correlated with hot (430-440 deg C) measurements and calculations of the fast flux above 1 Mev in th… more

FORMATION CONSTANTS OF SOME RARE-EARTH COMPLEXES

Description: The stepwise formation constants for complexes between the trivalent metals lanthanum, yttrium, and all of the rare earths, except promethium, and the ligands isobutyrate (IBU), alpha -hydroxyisobutyrate (AHIB) and alpha , BETA , BETA '-trihydroxyisobutyrate (THIB) were measured at 25 deg C and an ionic strength of 0.5M (NaClO/sub 4/). For lanthanum and the first half of the rare- earth series, the magnitude of the formation constants increased in the order IBU, AHIB, THIB. For the remainder of… more

Graphite Modular Reactor with Cooled Metal Core Outlet End Support Plate

Description: The modular designs appear attractive in that the reactor core lateral support is provided by the modules themselves rather than externally as with a bundled core. Types B and C provide a means of reducing the inter-element and intermodular leakage flow. This tends to enhance the reliability of the reactor core by decreasing the probability of a progressive overall failure of the core initiated by a mid-core rupture of one of the fuel elements. The graphite inner reflector and lateral suppor… more

High-Temperature Gas-Cooled Reactor Critical Experiment and Its Application

Description: Two types of critical experiments were conducted in support of the 40- Mw(e) Peach Bottom HTGR nucleardesign program. The first was the test-lattice experiment, where detailed measurements of reaction rates were examined in a lattice having a cold neutron spectrum characteristic of the HTGR. This program provided a method for checking the resonance integral of thorium, the Doppler coeificient of thorium, the detailed flux distribution in the lattice, and control-rod effectiveness within a cell.… more
