Alternate immersion stress corrosion testing of 5083 aluminum

Description: The stress corrosion susceptibility of Type 5083 aluminum--magnesium alloy in plate form and press-formed shapes was determined in the short transverse direction. C-ring type specimens were exposed to alternate immersion in a sodium chloride solution. The test equipment and procedure, with several innovative features, are described in detail. Statistical test results are listed for seven thermomechanical conditions. A certain processing scheme was shown to yield a work-strengthened part that is… more

Analytical approaches to and interpretations of data on time, rate, and cause of death of mice exposed to external gamma irradiation

Description: Young adult male and female mice of inbred strains, A, BALB/c, C57BL/6, and C57L, and B6CF/sub 1/ and F/sub 2/ hybrids were exposed to daily duration-of-life external /sup 60/Co ..gamma.. irradiation. Age at death was recorded, and most decedents were necropsied to ascertain occurrence of major types of tumors. Age- and cause-specific mortality or incidence rates were derived, and their regressions on age were fitted with polynomial equations by least-squares procedures. Age-specific and age-ad… more

Argus glass laser target alignment system

Description: Proper laser infrared irradiation of ball targets 10 to 100 ..mu..m in diameter requires micrometre-step positioning of the system's optical elements. A central control console has been designed that gives the operator nearly complete control of this complex operation. Twin alignment lasers can be operated from the console. Devices can be inserted in the beam lines, mirrors moved, and the target ball aligned, all with fine precision. The focus position can be viewed by closed-circuit TV monitor… more

Assessment of need for developing and implementing technical and skilled-worker training for the solar-energy industry. Final report

Description: A forecast for solar-trained manpower needs was produced based on projected demand for solar systems and manpower requirement for solar systems. A skills analysis was made to determine the types of training required to produce manpower capable of performing the tasks identified in the task analysis. (MHR)

Automated controlled-flow air infiltration measurement system

Description: An automated, controlled-flow air infiltration measurement system is described. This system measures total air flow, a volume per unit time, due to infiltration in a test space. Data analysis is discussed and the mixing problem is analyzed. Different modes of operating the system are considered: concentration decay, continuous flow in a single chamber; and continuous flow in a multichamber enclosure. Problems associated with the use of nitrous oxide as a tracer gas are described.

Barstow isolation and meteorological data base

Description: A data base containing insolation and meteorological parameters at 15 minute intervals for the entire year of 1976 at Barstow, California has been prepared on computer compatible magnetic tape. The observed insolation values obtained by the Southern California Edison Company and meteorological values obtained by the Federal Aviation Agency which form the data base have been carefully checked for internal consistency. The data tape is written in a modified form of the SOLMET format and is availa… more

Blanket design for the mirror fusion/fission hybrid reactor

Description: The evolution of this particular blanket concept is described. The geometry of the mirror reactor blanket and the replacement methods that are employed are described. The sub-module design and its thermal-hydraulic considerations, the nuclear model geometry and compositions, and the nuclear calculational method are described. A brief reference is made to calculational vs. experimental results.

Building and community systems resource-allocation model. Final report

Description: The paper discusses development of a resource allocation methodology for the BCS group to determine which energy conservation projects to fund if it is not possible to support all candidate programs and to determine how many projects to fund in one area to maintain minimal duplication. The current status of the methodology is presented. Section II deals with the technique used to evaluate a single portfolio. Section III describes the algorithm used to select the portfolios for evaluation. The s… more

Characterization of operating conditions for gas/water heat recovery steam generators

Description: The possible operating points of air/water and helium/water steam generators are parametrically presented. Calculation procedures and a sample computer program listing are provided. Multiple saturated steam conditions are shown to be attainable with the same gas inlet and exit temperatures. Design considerations of heat transfer surface area and pumping requirements are also discussed.

Clinch River Breeder Reactor Plant steam generator: FEW tube test model post test examination

Description: The Steam Generator Few Tube Test (FTT) is part of an extensive testing program being carried out in support of the Clinch River Breeder Reactor Plant (CRBRP) steam generator design. The testing of full-length seven-tube evaporator and three-tube superheater models of the CRBRP design was conducted to provide steady-state thermal/hydraulic performance data to full power per tube and to verify the absence of multi-year endurance problems. The problems encountered with the mechanical features of … more
