Assessment of nuclear safety and nuclear criticality potential in the Defense Waste Processing Facility. Revision 1

Description: The S-Area Defense Waste Processing Facility (DWPF) will initially process Batch 1 sludge in the sludge-only processing mode, with simulated non-radioactive Precipitate Hydrolysis, Aqueous (PHA) product, without the risk of nuclear criticality. The dilute concentration of fissile material in the sludge combined with excess of neutron absorbers during normal operations make criticality throughout the whole process incredible. Subsequent batches of the DWPF involving radioactive precipitate slurr… more

Pressure induced metallization of the Mott Insulator VI{sub 2}

Description: Using diamond anvil cells, {sup 129}I Moessbauer spectroscopy (MS) and resistivity measurements were carried out in the layered antiferromagnet VI{sub 2} at 0-45 GPa and 4-300 K. MS to 15 GPa revealed an impressive increase in Neel temperature and a slight increase in transferred hyperfine field. Pressure behavior of R(P,T), in particular near the metal-insulator pressure P{sub c}=44 GPa, is described. Being the lightest transition metal (TM) in the isostructural (TM)I{sub 2} series, the V{sup … more

High pressure metallization of Mott Insulators: Magnetic, structural and electronic properties

Description: High pressure studies of the insulator-metal transition in the (TM)I{sub 2} (TM = V, Fe, Co and Ni) compounds are described. Those divalent transition-metal iodides are structurally isomorphous and classified as Mott Insulators. Resistivity, X-ray diffraction and Moessbauer Spectroscopy were employed to investigate the electronic, structural, and magnetic properties as a function of pressure both on the highly correlated and on the metallic regimes.

Next-Step scientific objectives, targets, and parameters for reversed-field-pinch (RFP) magnetic fusion energy (MFE) systems: Preliminary thoughts

Description: The purpose of this document is the quantitative definition of objectives, targets, and parameters of the Next-Step device to follow the present RFX experiment; this device is given the name RFXNS. Although developed over five years ago, much of the material distilled into the 1988 RFP tactical plan is useful in establishing the goals and parameters of RFXNS. This earlier plan established tentative parameters of an RFP next step based on: predictions of RFP ignition and commercial-reactor devic… more

Nuclear electric propulsion for future NASA space science missions

Description: This study has been made to assess the needs, potential benefits and the applicability of early (circa year 2000) Nuclear Electric Propulsion (NEP) technology in conducting NASA science missions. The study goals are: to obtain the performance characteristics of near term NEP technologies; to measure the performance potential of NEP for important OSSA missions; to compare NEP performance with that of conventional chemical propulsion; to identify key NEP system requirements; to clarify and depict… more

Robotic weld overlay coatings for erosion control. Quarterly technical progress report, April 1993--June 1993

Description: Twelve weld overlay hardfacing alloys have been selected for preliminary erosion testing based upon a literature review. Four of the selected coatings were deposited on a 1018 steel substrate using plasma arc welding process. During the past quarter, the remaining eight coatings were deposited in the same manner. Ten samples from each coatings were prepared for erosion testing. Microstructural characterization of each coating is in progress. This progress report describes coating deposition and… more
