3-D slug flow heat transfer analysis of coupled coolant cells in finite LMFBR bundles
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 established in such characteristic rod bundle regions, a 3-D heat transfer analysis seems to be mandatory. This implies that the results of fully developed heat transfer analyses are by far too conservative.

16. 3 eV neutron capture in /sup 107/Ag: nuclear structure of /sup 108/Ag. [Transitions, J correlations,. pi. ]
The ..gamma.. rays from neutron capture in the 0- resonance of /sup 107/Ag at 16.3 eV were studied. Thirteen primary transitions populate spin 1 levels in /sup 108/Ag below an energy of 1.5 MeV. Transitions from low lying levels change in intensity by as much as a factor of 2 between thermal neutron capture (largely spin 1) and the 0- resonance, indicating a strong correlation of the population with level spin. 7 references.

30-MJ superconducting magnetic energy storage (SMES) unit for stabilizing an electric transmission system
Electric power systems that have major loads and generation centers separated by large distances may experience low-frequency power oscillations. This type of oscillation has occurred on the Pacific ac intertie that connects southern California and the Pacific Northwest. A separate, almost parallel, dc-transmission line also connects these areas. The Bonneville Power Administration, which operates this transmission system, has overcome the instability by controlling the power transmitted on the dc-transmission line. A 30-MJ (8.4-kWh) superconducting magnetic energy storage unit with a 10-MW converter could also provide damping for this instability. The conceptual design of the 30-MJ coil and the cryogenic and electrical components of the system are described. The system is to operate at a maximum current of 5 kA and will modulate the ac Intertie at 0.35 Hz. Discharge will be controlled to retain a minimum stored energy of 20 MJ to limit cyclic strains in the coil and ac losses in the conductor. The conductor will be made of multistrand-copper and copper-matrix, multifilament NbTi superconducting wires on a stainless steel mandrel.

150-kV, 80-A solid state power supply for neutral beam injection
A 150-kV, 80-A power supply and neutral beam test facility is now operational at the Lawrence Berkeley Laboratory, Berkeley, California. This supply uses banks of 450-V electrolytic capacitors for over 10/sup 6/ joules of energy storage. SCR switches control the power flow to the neutral beam accelerator. Turn on and off times of a few microseconds are possible. An auxiliary capacitor bank also uses SCR switches to provide regulation (''flat-topping'') of the main bank output by switching in additional capacitors as the main bank discharges. Air-operated switches are used to connect the main-bank sections in parallel for charging and series or parallel for discharge, depending on the operating voltage desired. A single digital switch sets the desired operating voltage. Filament and arc power supplies are also solid state. With the exception of the suppressor supply which has one vacuum tube the complete neutral beam system uses all solid state components.

400-MWe Consolidated Nuclear Steam System (CNSS). 1200-MWt Phase 2A interim studies. [PWR]
The Phase 2A interim studies of the Consolidated Nuclear Steam System (CNSS) consisted of a number of separate task studies addressing the design concepts developed during the Phase 1 study reported in BAW--1445. The purpose of the interim studies was to better establish overall concept feasibility from both a hardware and economic standpoint, to make modification and additions to the design where appropriate, and to understand and reduce the technical risks in critical areas of the design. The work on these task studies included input from Barberton, Mt. Vernon, and the Alliance Research Center as well as United Engineers and Constructors (UE and C). The UE and C work was carried out under a separate DOE contract.

1975 energy conditions in the South
This report depicts energy supply and demand conditions in the South in 1975 and highlights differences in production and utilization patterns relative to the United States (some of the consumption data is for 1974). Significant changes during the previous three years are noted to provide continuity with the predecessor report, Energy Conditions in the South: 1972. The most important changes are the substantial increase in nuclear generation of electricity, the absolute and relative decline in oil and gas production, and the increase in per capita energy consumption relative to the nation. Each state within the region is described in detail to ascertain important sub-regional differences in energy conditions. The intent is to provide a description rather than analysis of regional energy patterns, noting variations and emphasizing the comparative advantages of the South. Such a presentation can yield insight into the future role of the region in contributing to the economic growth and welfare of the nation as its natural resource base is depleted and the transition to alternative energy sources is made.

2XIIB plasma confinement experiments
This paper discusses results of plasma-confinement experiments in the 2XIIB magnetic mirror device. We report experiments attempting to achieve field-reversal using neutral-beam injection in which the central magnetic field is reduced by 90% but field lines are not closed. Experiments with different neutral-beam aiming show that at constant beta both electron temperature and the energy-confinement parameter (n tau) increase at larger radius. Finally, we discuss recent improvements in electron temperature and microinstability measurements.

Absolute measurements of the /sup 233/U (n,f) cross section between 0. 13 and 8. 0 MeV. [Cross sections, 0. 13 to 8. 0 MeV]
The fast neutron fission cross section of /sup 233/U was measured absolutely between 0.13 and 8.0 MeV. The absolute cross section values were obtained by low geometry alpha counting and isotopic dilution analysis of various /sup 233/U samples, 2..pi..-detection of the fission fragments with an ionization chamber, and the measurement of the neutron flux with several black neutron detectors. Absolute cross sections were obtained with a 2 to 3% uncertainty over the most important energy range.

Accelerator breeding of fissile materials
The accelerator-driven breeder can extend an essential energy resource, fissile fuel for nuclear reactors, by a very large factor. Symbiotic breeders could be brought on line in a shorter period of time with favorable performance predictability. The economics of using accelerator breeding of fertile-to-fissile elements will become favorable as natural fissile material becomes scarce.

Accelerator control using RSX-11M and CAMAC
This paper describes a computer-control system for a superconducting linear accelerator currently under development at Argonne National Laboratory. RSX-11M V3.1 running on a PDP 11/34 is used with CAMAC hardware to fully control 22 active beam-line elements and monitor critical accelerator conditions such as temperature, vacuum, and beam characteristics. This paper contrasts the use of an RSX compatible CAMAC driver for most CAMAC I/O operations and the use of the Connect-to-Interrupt Vector directive for fast ADC operation. The usage of table-driven software to achieve hardware configuration independence is discussed, along with the design considerations of the software interface between a human operator and a computer-control system featuring multi-function computer-readable control knobs and computer-writable displays which make up the operator's control console.

Accomplishments: AE characterization program for remote flaw evaluation. [BWR; PWR]
The purpose of the program is to develop an experimental/analytical evaluation of the feasibility of detecting and analyzing flaw growth in reactor pressure boundaries by means of continuously monitoring acoustic emission (AE). The investigation is devoted exclusively to ASTM Type A533, Grade B, Class 1 material. The basic approach to interpretive model development is through laboratory testing of 1 to 1/sup 1///sub 2/ inch (25.4 to 38 mm) thick fracture mechanics specimens in both fatigue and fracture at both room temperature and 550/sup 0/F (288/sup 0/C). Seven parameters are measured for each AE signal and related to fracture mechanics functions. AE data from fracture testing of 6 inch (152 mm) wall pressure vessels are also incorporated in analysis.

ACES demonstration: construction, startup, and performance report
A 2000-ft/sup 2/ single-family residence was constructed during the second quarter of 1976 to demonstrate the energy-conserving features of additional insulation, a ventilation cooling cycle, and the Annual Cycle Energy System (ACES). The ACES is an integrated heating and cooling system that supplies space heating, hot water, and space cooling using a heat pump and low-temperature thermal storage. Included in this report are a discussion of the construction techniques employed and the problems encountered during construction, a description of the ACES concept and the ACES mechanical package, and a discussion of the ACES performance and the experiences obtained during initial operation of the ACES. Continuous operation and data collection were begun in May 1977. Performance data from November 1977 through March 1978 have shown a seasonal heating coefficient of performance of 2.77 for the ACES, giving a 63% energy reduction compared to electric resistance space and water heating.
