Assessment of first wall damage from target x-ray emission and scattered laser light for the National Ignition Facility

Description: Predictions for NIF ICF target x-ray emission are presented. Validation experiments confirm the key features of the x-ray emissions and their effects on the NIF chamber B{sub 4}C first wall. Predictions of a possible first wall 0.35-{mu}m laser radiation compared to more experimental results conducted to determine B{sub 4}C response all suggest B{sub 4}C is an acceptable first wall material.

Co-firing high sulfur coal with refuse derived fuels. Technical progress report No. 6, January--March 1996

Description: The objectives for this quarter of study on the co-firing of high sulfur coals with refuse derived fuels were two-fold.

Computational modeling of ultra-short-pulse ablation of enamel

Description: A computational model for the ablation of tooth enamel by ultra-short laser pulses is presented. The role of simulations using this model in designing and understanding laser drilling systems is discussed. Pulses of duration 300 sec and intensity greater than 10{sup 12} W/cm{sup 2} are considered. Laser absorption proceeds via multi-photon initiated plasma mechanism. The hydrodynamic response is calculated with a finite difference method, using an equation of state constructed from thermodynami… more

Conference Committee and Related Procedures: An Introduction

Description: Conference committees generally are free to conduct their negotiations as they choose, but they are to address only the matters on which the House and Senate have disagreed. Moreover, they are to propose settlements that represent compromises between the positions of the two houses. When they have completed their work, they submit a conference report and joint explanatory statement, and the House and Senate vote on accepting the report without amendments. Sometimes conference reports are accomp… more

Description: The objective of this project was to characterize metallic emissions from representative coals and develop strategies for their control. A technique for flue gas desulfurization is the use of calcium based sorbents, and the degree of metals capture of these sorbents under different conditions will be researched. The objective of the first year of the study was to understand the evolution of metallic aerosol size distributions and the capture characteristics of various sorbents. Also, the metall… more

Demonstration of a vapor density monitoring system using UV radiation generated from quasi-phasematched SHG waveguide devices

Description: Many industrial applications require non-intrusive diagnostics for process monitoring and control. One example is the physical vapor deposition of titanium alloys. In this paper we present a system based on laser absorption spectroscopy for monitoring titanium vapor. Appropriate transitions for monitoring high rate vaporization of titanium require extension of available IR diode technology to the UV. The heart of this vapor density monitoring system is the 390nm radiation generated from quasi-p… more

Development of a video-based slurry sensor for on-line ash analysis. Fifth quarterly technical progress report, October 1, 1995--December 31, 1995

Description: Automatic control of fine coal cleaning circuits has traditionally been limited by the lack of sensors for on-line ash analysis. Although several nuclear-based analyzers are available, none have seen widespread acceptance. This is largely due to the fact that nuclear sensors are expensive and tend to be influenced by changes in seam type and pyrite content. Recently, researchers at VPI&SU have developed an optical sensor for phosphate analysis. The sensor uses image processing technology to ana… more

Differential processing to separate radionuclide and VOC from soil and ground water by air-sparged hydrocyclone technology. Final report

Description: There are a wide variety of radioactive, toxic, and heavy metal contaminants in the ground waters and soils at DOE facilities. Some of the most common are uranium, technetium, trichloroethylene, and polychlorinated biphenyls. The project is a challenging task based on several key factors. For the removal of radio nuclide or heavy metal particles, first, on a mass fraction basis there is only a small amount of radionuclide particles in either writer or soil. In this way, a successful separation … more

Description: This project attempts to demonstrate the effectiveness of exploiting thin-layered, low-energy deposits at the distal margin of a prograding turbidite complex through the use of hydraulically-fractured, horizontal or high-angle wells. The combination of a horizontal or high-angle well and hydraulic fracturing will allow greater pay exposure than can be achieved with conventional vertical wells while maintaining vertical communication between thin interbedded layers and the wellbore. A high-angle… more

Eliminating the possibility at Chernobyl 4 of recriticality with positive feedback

Description: We have recently published an article in which we discuss means by which plutonium and other fissile material stored underground could reach criticality with positive feedback and therefore explosive potential. The Chernobyl rubble involving hundreds of tons of material is similar in some respects to the systems analyzed in the paper, and the practices there to control criticality may well increase the probability of a second event at Chernobyl 4. This paper explores the Chernobyl situation and… more
