60-inch annular pitch polisher for LASL's LASER-fusion effort

Description: The Antares laser will require that about 100 high-precision NaCl windows of 18-in. diameter be produced, maintained, and repaired. To aid the industry in achieving the required production rates, a polishing development program was undertaken by LASL's Laser Division in collaboration with the Air Force and International Laser Systems. The design and initial shakedown of the polishing machine is described. Preliminary results indicate the machine's design is sound, its operation is generally sim… more

BWR pool dynamics in a loss of coolant accident. Calculation of the air-venting phase

Description: The authors calculated the air-venting phase of a loss of coolant accident (LOCA) in a BWR pool using both compressible and incompressible finite difference schemes, and compared the results with experiments made at the University of California, Los Angeles and the Massachusetts Institute of Technology. The incompressible approach was found to be the most effective, because of the very low flow Mach numbers involved. Theory and experiment were in good agreement.

Cadmium sulfide/copper sulfide heterojunction cell research. Technical progress report No. 2, January 1--March 31, 1978

Description: Poor adhesion of CdS films to zinc-plated copper foil substrates has been eliminated by depositing somewhat thinner films than earlier and by using the mat (as opposed to the smooth) side of the electroformed copper foil for deposition. Particle spatter effects have been reduced and cells of 4 cm/sup 2/ area have been produced with average efficiency of 5.4%. Use of Zn--plated Cu, Mo, Zn--plated Mo and glass substrates appears to influence the etching behavior of CdS films in dilute chromic aci… more

Core Power and Decay Time Limits for a Disabled LOFT ECCS

Description: An analysis was done to determine at what LOFT total core power (nuclear plus decay power) the ECCS could be inoperable. The criteria used for the analysis was that the maximum fuel clad temperature should not exceed 1650/sup 0/F given a loss of coolant. Calculations for natural convection cooling of the fuel by air with an inlet temperature of 580/sup 0/F determined that the limiting core power is 25 kW (discounted by 15 percent to 20 percent for potential uncertainties). Shutdown times are li… more

Droplet phase characteristics in liquid-dominated steam--water nozzle flow

Description: An experimental study was undertaken to determine the droplet size distribution, the droplet spatial distribution and the mean droplet velocity in low-quality, steam-water flow from a rectangular cross-section, converging-diverging nozzle. A unique forward light scattering technique was developed for droplet size distribution measurements. Droplet spatial variations were investigated using light transmission measurements, and droplet velocities were measured with a laser-Doppler velocimeter (LD… more

Evaluation of alternate LOFT secondary heat removal systems

Description: The first system proposed for test in the LOFT facility is a pressurized water reactor system, designed to operate continuously for up to 1600 effective full power hours at 50 MWt. Because of the experimental nature of the plant and its relatively short life, utilization of the reactor heat for power generation is not practical. Consequently, it is necessary to provide a secondary heat removal system capable of continuously removing up to 170 x 10/sup 6/ Btu/hr (50 MWt) from the primary coolant… more

Evaluation of selected chemical processes for production of low-cost silocon. (Phases I and II. ) Final report, October 9, 1975--July 9, 1978. Silicon Material Task, Low-Cost Solar Array Project

Description: The zinc reduction of silicon tetrachloride in a fluidized bed of seed particles to yield a granular product was studied along with several modifications of the thermal decomposition or hydrogen reduction of silicon tetraiodide. Although all contenders were believed to be capable of meeting the quality requirements of the LSA Project, it was concluded that only the zinc reduction of the chloride could be made economically feasible at a cost below $10/kg silicon (1975 dollars). Accordingly, subs… more

Feasibility study for computerized automation of EPA Region II Technical Support Branch

Description: Three options are presented for automating the chemistry laboratories at the Surveillance and Analysis Division, Environmental Protection Agency , at Edison, New Jersey. The laboratory served New York State, New Jersey and Puerto Rico. Each option was found to be cost-effective. For two of the systems, existing EPA laboratory software would be used without (option 1) and with (option 2) data management. For the third system, laboratory and data functions would be implemented on a different comp… more

Human as a component of a nuclear material safeguard system

Description: Many human vigilance experiments are summarized and principles are extracted which should be useful in designing and evaluating a nuclear material safeguard system. A human is a poor observer and is not a dependable part of any man-machine system when required to function as an observer. There are a few techniques which improve his performance by providing feedback. A conceptual model is presented which is helpful in design and evaluation of systems. There is some slight experimental support fo… more

Material Control System Simulator

Description: Design and assessment of the material control aspect of nuclear safeguard systems requires consideration of three types of functional elements: (1) material handling or processing, (2) actions of adversaries in their attempt to divert nuclear materials from their normal containment, and (3) components of material control and accounting and physical security systems that detect and respond to stimuli generated by the adversary actions. This paper describes a Material Control System Simulator (MC… more
