1-1/2-Loop Semiscale Isothermal Test Program: Program and System Description in Support of Experiment Data Reports.

Description: The isothermal test series is part of the Semiscale Blowdown and Emergency Core Cooling (ECC) Project conducted by Aerojet Nuclear Company for the U. S. Atomic Energy Commission. The test series consisted of ten blowdown tests and five hot-wall tests with emphasis on emergency core coolant delivery. The blowdown tests were conducted to investigate the effects of lower plenum geometry, heat transfer configuration, ECC injection location, downcomer gap size, and break size.

3-D slug flow heat transfer analysis of coupled coolant cells in finite LMFBR bundles

Description: A three-dimensional single region slug flow heat transfer analysis for finite LMFBR rod bundles using a classical analytical solution method has been performed. According to the isolated single cell analysis, the results show that the peripheral clad temperature variation as well as the thermal entrance length are strongly dependent upon the degree of irregularity displayed by various coolant geometries. Since under the present LMFBR conditions, fully-developed temperature fields may hardly be … more

120-keV Neutral-Beam Injection System Development

Description: The neutral-beam injection systems for the next generation of U. S. fusion experiments (TFTR, MX, Doublet III) have requirements that considerably exceed the present state of development. TFTR, for example, desires 20 MW of 120-keV deuterium atoms in pulses of 0.5-sec duration. The neutral-beam systems needed to meet these demands will be large and complex and will require much development effort. In order to develop components for these new systems, a new, large test facility was constructed. … more

200-GeV ISA with room temperature magnets

Description: A conceptual design study of 200-GeV proton intersecting storage accclerators with room temperature magnets is presented. The key to this study was thc desire to keep the electric power consumptiom to an acceptable level (40 MW). The design has been optimized by choosing small-gap (4 cm) aluminum coil dipoles operating at about 15 kG. The luminosity of this machine is limited to about 10/sup 32/ cm-/sup -2/ sec/sup -1/ by transverse space-charg e effects. An order of magnitude higher luminositi… more

325-B FACILITY

Description: Due to the continuing high air sample results over the past six months, a thorough review of conditions and procedures was felt necessary for 325-B facility. A complete survey of the facility was made, looking for possible or definite problems. A discussion about procedures and conditions was held with all Radiation Monitoring personnel involved with the facility. The following items we felt needed attention to improve the working environment for the personnel in the facility. 1. Recommend glov… more

Absolute differential cross sections over the entire angular range for the reaction /sup 3/H(d,n)/sup 4/He at 7. 0 and 10. 0 MeV

Description: Differential cross sections for the reaction /sup 3/H(d,n)/sup 4/He have been measured at 7.00 and 10.00 MeV using the time-of-flight technique. By measuring both /sup 3/H(d,n)/sup 4/He and /sup 2/H(t,n)/sup 4/He at the same center of mass, energy-complete distributions between 0/sup 0/ and 180/sup 0/ have been obtained. The absolute scales have been established within +- 1.5 percent by using the accurate /sup 2/H(t,/sup 4/He)n cross sections at 20.0 MeV as a standard.

Acceleration experienced by thermal converter implanted in calves. [Acceleration from walking, falling, and jumping]

Description: The objective of this study was to determine acceleration levels experienced by the ERDA thermal converter unit implanted abdominally in a calf. A full-scale weighted mock-up of the thermal converter was fabricated containing a triaxial accelerometer. The mock-up was implanted in calf cadavers which were subjected to falls from an operating table. Highest acceleration recorded was 34 g. The mock-up was implanted in living animals and acceleration measurements made under various maneuvers includ… more

Acceptable TRU packaging for interim storage and/or terminal isolation: FY-1977 final report

Description: A program was conducted for the definition and demonstration of acceptable waste packages for defense transuranic waste for interim storage and terminal isolation. During FY-1977, a Contractor Questionnaire was used to gather pertinent data and to assess contractor concerns. This information was integrated into basic application data in the form of a checklist. Conceptual Container Design Specifications were developed by analyzing and evaluating the application data against Federal Regulations … more

Actinide partitioning and transmutation program. Progress report, July 1--September 30, 1977

Description: In Purex process modifications, two cold runs with mixer-settlers were made on the extraction and stripping of ruthenium and zirconium without the presence of uranium. Efforts in actinide recovery from solids were directed toward the determination of dissolution parameters in various reagents for /sup 241/Am and /sup 239/Pu oxide mixtures, /sup 233/U oxide, /sup 237/Np oxide, /sup 244/Cm oxide, /sup 232/Th oxide, and PuO/sub 2/.

Active Devices for High Temperature Microcircuitry

Description: As part of a program to develop high temperature electronics for geothermal well instrumentation, a number of solid state diode and transistor types were characterized from room temperature to 300/sup 0/C. The temperature dependence and aging stability of transport and leakage properties were measured. Included in the study were silicon diodes, bipolar transistors, JFETs, MOSFETs, and GaAs MESFETs and JFETs. In summary the results are: diodes and bipolar transistors became extremely leaky at hi… more

Advanced Thermohydraulic Simulation Code for Transients in LMFBRs (SSC-L code)

Description: Physical models for various processes that are encountered in preaccident and transient simulation of thermohydraulic transients in the entire liquid metal fast breeder reactor (LMFBR) plant are described in this report. A computer code, SSC-L, was written as a part of the Super System Code (SSC) development project for the "loop"-type designs of LMFBRs. This code has the self-starting capability, i.e., preaccident or steady-state calculations are performed internally. These results then serve … more
