A laser scanning system for metrology and viewing in ITER

Description: The construction and operation of a next-generation fusion reactor will require metrology to achieve and verify precise alignment of plasma-facing components and inspection in the reactor vessel. The system must be compatible with the vessel environment of high gamma radiation (10{sup 4} Gy/h), ultra-high-vacuum (10{sup {minus}8} torr), and elevated temperature (200 C). The high radiation requires that the system be remotely deployed. A coherent frequency modulated laser radar-based system will… more

Thermomechanical processing of tungsten-copper composites

Description: A tungsten-40 wt% Cu composite was consolidated by liquid-phase sintering and further processed to full density by a number of deformation methods. Fully dense materials were obtained by hot extrusion or cold rolling of the W-Cu composite. Subsequent processing by cold rolling, cold swaging, or hot swaging did not produce large changes in the aspect ratio of the W particles. The materials develop high hardness with small grain sizes of 5 {mu}m or less. The work-hardening, recrystallization, and… more

Advanced byproduct recovery: Direct catalytic reduction of sulfur dioxide to elemental sulfur. Second quarterly technical progress report, January--March 1996

Description: In the more than 170 wet scrubber systems in 72,000 MW of US, coal-fired, utility boilers, the SO{sub 2} removed from the boiler flue gas is sorbed, and the sulfated sorbent must be disposed of. The use of regenerable sorbents has the potential to reduce this disposal problem. The team of Arthur D. Little, Tufts Univ., and Engelhard Corp. are conducting Phase I of a 4.5-year, two-phase effort to develop and scale-up a direct, single-stage, catalytic process for converting SO{sub 2} to S. This c… more

Solar central receiver technology: the Solar Two Project

Description: Solar Two will be the world`s largest operating solar central receiver power plant. It is expected to begin operating in April 1996; it is currently undergoing start-up and checkout. The plant will use sunlight reflected from 1926 sun-tracking mirrors to heat molten nitrate salt flowing in a heat exchanger (receiver) that sits atop a 200 foot tower. The heated salt will be stored in a tank for use, when needed, to generate superheated steam for producing electricity with a conventional Rankine-… more

Demonstration of close-coupled barriers for subsurface containment of buried waste

Description: A close-coupled barrier is produced by first installing a conventional cement grout curtain followed by a thin inner lining of a polymer grout. The resultant barrier is a cement polymer composite that has economic benefits derived from the cement and performance benefits from the durable and resistant polymer layer. Close-coupled barrier technology is applicable for final, interim, or emergency containment of subsurface waste forms. Consequently, when considering the diversity of technology app… more

Office of Inspector General report on audit of Department of Energy management and operating contractor available fees

Description: The Office of Procurement and Assistance Management has proposed changes to the method used to annually calculate and negotiate ``for profit`` management and operating contractor available fees. This proposal will increase contractor fees in exchange for the contractor`s purported assumption of additional risk. In 1991, the Department, through the Accountability Rule, increased contractor fees as an incentive to improve contractor performance and accountability. Despite the lack of measurable b… more

High-resolution spectroscopy using synchrotron radiation for surface structure determination and the study of correlated electron systems

Description: The surface structure of three molecular adsorbate systems on transition metal surfaces, ({radical}3 x {radical}3)R30{degrees} and (1.5 x 1.5)R18{degrees} CO adsorbed on Cu(111), and c(2x2) N2/Ni(100), have been determined using Angle-Resolved Photoemission Extended Fine Structure (ARPEFS). The adsorption site and bond lengths are reported for the adsorbate-metal bond and the first two substrate layers. The ARPEFS diffraction pattern of the shake-up peak for c(2x2) N2/Ni(100) is also discussed.… more

Surface water drainage system. Environmental assessment and finding of no significant impact

Description: This Environmental Assessment (EA) is written pursuant to the National Environmental Policy Act (NEPA). The document identifies and evaluates the action proposed to correct deficiencies in, and then to maintain, the surface water drainage system serving the Department of Energy`s Rocky Flats Environmental Technology Site (Site), located north of Golden, Colorado. Many of the activities proposed would not normally be subject to this level of NEPA documentation. However, in many cases, maintenanc… more

A survey of commercially available manipulators, end-effectors, and delivery systems for reactor decommissioning activities

Description: Numerous nuclear facilities owned by the U.S. Department of Energy (DOE) are under consideration for decommissioning. Currently, there are no standardized, automated, remote systems designed to dismantle and thereby reduce the size of activated reactor components and vessels so that they can be packaged and shipped to disposal sites. Existing dismantling systems usually consist of customized, facility-specific tooling that has been developed to dismantle a specific reactor system. Such systems … more

Effects of oxygen cover gas and NaOH dilution on gas generation in tank 241-SY-101 waste

Description: Laboratory studies are reported of gas generation in heated waste from tank 241-SY-101. The rates of gas generation and the compositions of product gas were measured. Three types of tests are compared. The tests use: undiluted waste, waste diluted by a 54% addition of 2.5 M NaOH, and undiluted waste with a reactive cover gas of 30% Oxygen in He. The gas generation rate is reduced by dilution, increased by higher temperatures (which determines activation energies), and increased by reactions of … more

An Investigation of the Value of Color in Hard Copy Output

Description: The objectives of this research were to: (1) augment existing research regarding the impact of information retention resulting from the application of redundant color codes; and (2) determine whether the application of color in hard-copy documents has a positive influence in business reports by non-color deficient subjects. This research was an extension of work done by Lamberski and Dwyer (1983) and Moore and Dwyer (1991). Both studies were hard copy based and focused on the impact of informat… more

Effects of thermal aging on fracture toughness and Charpy-impact strength of stainless steel pipe welds

Description: Degradation of fracture toughness, tensile, and Charpy-impact properties of Type 304 and 304/308 SS pipe welds due to thermal aging was studied at room temperature and 290 C. Thermal aging of SS welds results in moderate decreases in charpy-impact strength and fracture toughness. Upper-shelf energy decreased by 50-80 J/cm{sup 2}. Decrease in fracture toughness J-R curve or J{sub IC} is relatively small. Thermal aging had no or little effect on tensile strength of the welds. Fracture properties … more

Research and development of a phosphoric acid fuel cell/battery power source integrated in a test-bed bus. Final report

Description: This project, the research and development of a phosphoric acid fuel cell/battery power source integrated into test-bed buses, began as a multi-phase U.S. Department of Energy (DOE) project in 1989. Phase I had a goal of developing two competing half-scale (25 kW) brassboard phosphoric acid fuel cell systems. An air-cooled and a liquid-cooled fuel cell system were developed and tested to verify the concept of using a fuel cell and a battery in a hybrid configuration wherein the fuel cell suppli… more
