SNAP 19 Pioneer F and G. Final report

Description: The generator developed for the Pioneer mission evolved from the SNAP 19 RTG's launched aboard the NIMBUS III spacecraft. In order to satisfy the power requirements and environment of earth-escape trajectory, significant modifications were made to the thermoelectric converter, heat source, and structural configuration. Specifically, a TAGS-2N thermoelectric couple was designed to provide higher efficiency and improved long term power performance, and the electrical circuitry was modified to yie… more

Development of a thermionic-reactor space-power system. Final summary report

Description: Initial experimental work led to the award of the first AEC thermionic contract on May 1, 1962, for the development of fission heated thermionic cells with an operating life of 10,000 hours or more. Two types of converters were fabricated: (1) electrically heated, and (2) fission heated where the fuel was either uranium carbide or uranium oxide. Competition between GGA and GE was climaxed on July 1, 1970 by the award to GGA of a contract to develop an in-core thermionic reactor. This report is … more

A proposal to study hard hadron - hadron collisions

Description: We propose a novel technique to study hadron-hadron collisions in which a significant fraction of the available energy is carried off in directions transverse to the beam. The technique is independent of the details of the final state so is ideally suited to searching for the jet-like particle clusters predicted by the parton model. The detector consists of a small calorimeter and several planes of 1 meter square proportional chambers.

Numerical model for two-dimensional hydrodynamics and energy transport. [VECTRA code]

Description: The theoretical basis and computational procedure of the VECTRA computer program are presented. VECTRA (Vorticity-Energy Code for TRansport Analysis) is designed for applying numerical simulation to a broad range of intake/discharge flows in conjunction with power plant hydrological evaluation. The code computational procedure is based on finite-difference approximation of the vorticity-stream function partial differential equations which govern steady flow momentum transport of two-dimensional… more

SEM Facility for Examination of Reactive and Radioactive Materials

Description: A scanning electron microscope (SEM) facility for the examination of tritium-containing materials is operational at Mound Laboratory. The SEM is installed with the sample chamber incorporated as an integral part of an inert gas glovebox facility to enable easy handling of radioactive and pyrophoric materials. A standard SEM (ETEC Model B-1) was modified to meet dimensional, operational, and safety-related requirements. A glovebox was designed and fabricated which permitted access with the glove… more

Drainage and Erosion Control Facilities: Field Performance Investigation

Description: Partial summary: "The drainage and erosion control facilities of 54 installations were observed to evaluate performance of surface and subsurface drainage systems, erosion control measures, and conditions of buried conduits and associated facilities. Although the facilities observed varied from only 1 to 30 years or more of age and it is recognized that basic demands have increased as well as the fact that design and construction procedures have been improved continuously, many of the old famil… more

Calculation of resonance self shielding in $sup 235$U

Description: Analytic and Monte Carlo calculations of the Bramblett- Czirr /sup 235/U transmission experiment STANuc!. Sci. Eng. 35, 350-357 (1969)! were performed. The numbcr of fissions from the uncollided flux could be calculated as a function of depth. The results of experiment and Monte Carlo calculations are tabulated and plotted; fission and total cross sections for /sup 235/U are shown. In view of the agreement between the analytic and Monte Carlo calculations, it appeared that the ENDF/B-III cross … more

Generalized method of computing carbon-diffusion profiles in austenitic stainless steels exposed to a sodium environment

Description: Numerous experimental observations on the carburization-decarburization behavior of austenitic stainless steels in hightemperature flowing sodium have been reported; however, quantitative predictions of carbon diffusion in the steels under specific environmental conditions have been difficult. A mathematical analysis for the process has been developed that incorporates (1) the thermodynamic and kinetic information for carbon in the alloys, (2) the thermal-mechanical treatment of the material (s… more

BREM II: a code for calculating the free--free Gaunt factor in an arbitrary atomic potential

Description: Free-free absorption is one of the dominant mechanisms governing the absorption of laser radiation by materials heated to temperatures of 0.5 to 2.0 eV. This report describes the theory, the listing, and the running instructions for a code which computes the free-- free Gaunt factor, arising from any given ionic or atomic potential. The calculation makes use of partial wave expansion. The code is capable of computing up to 95 partial waves. The code computes the necessary low energy wave functi… more

Evaporative heat transfer in vertical tubes at geothermal brine conditions: a preliminary investigation

Description: Overall heat-transfer coefficients were obtained in a single-tube loop for a smooth tube and two fluted tubes proposed for use in a geothermal brine upflow VTE pilot plant. Tests were run at steam temperatures from 250 to 390 deg F, flow rates of 0.5 to 2.5 gpm, and steam to brine DELTA Ts of 10 to 30 deg F using demineralized water and 3% NaCl solutions. In each case the liquid entering the tube flashed through a DELTA T equal to the steam- brine DELTA T. The tubes tested were a 3/4-in. smooth… more

Magnetic field induced far infrared transmission in bismuth

Description: High magnetic fields render the semimetal bismuth sufficiently transparent at far infrared frequencies to study effects not previously seen in reflection experiments. The frequency interval 10 to 400 cm/sup -1/ was explored at fields up to 100 kG using Fourier transform spectroscopic techniques and /sup 3/He-cooled bolometer detectors, and samples were cooled to liquid helium temperatures. Transmission was observed in all three principal crystal direc:. tions when the magnetic field was suffici… more

Neutron cross sections. Volume I. Resonance parameters

Description: In contrast to earlier editions, which presented in compact form a summary of the complete store of the neutron data files, this edition aims to provide those portions of neutron data considered to be of prime importance and best suited for inclusion in ready reference form. This volume contains thermal cross sections, resonance properties, resonance parameters, and bibliography for nuclides from H to /sup 257/Fm. Notation and nomenclature, considerations involved in the recommendations, and a … more
