Experimental and computer modeling studies of isotopically selective two-step laser photodissociation of small molecules

Description: The approach to laser isotope separation taken in this study is based on isotopically selective, two-step, laser photodissociation of small molecules. A primary goal of this study is the measurement of fundamental molecular processes which control the two-step, photodissociative isotope enrichment process. This objective has led to experimental measurements of uv photodissociation cross sections for vibrationally excited states of several small molecules, including the first cross section repor… more

Liquid centrifugation for nuclear waste partitioning

Description: The performance of liquid centrifugation for nuclear waste partitioning is examined for the Accelerator Transmutation of Waste Program currently under study at the Los Alamos National Laboratory.

An overview of copper-laser development for isotope separation

Description: We have developed a copper-laser pumped dye-laser system that addresses all of the requirements for atomic vapor laser isotope separation. The requirement for high average power for the laser system has led to the development of copper-laser chains with injection-locked oscillators and multihundred-watt amplifiers. By continuously operating the Laser Demonstration Facility, we gain valuable data for further upgrade and optimization.

Photo-induced cataphoretic isotope separation. Final report, June 15, 1976-June 15, 1981

Description: The original studies were undertaken to study the feasibility of radiation-induced cataphoretic separation. This part of the work is concerned with laser-induced cataphoretic separation in neon using a He-Ne 6328A laser. The basic concept of radiation-induced caphoretic isotope separation is based on the preferential excitation of one isotope with the result that one isotope is more readily ionized, and relatively more of its ions move toward the cathode in the dc discharge. For the later part … more

One-dimensional model for coaxial flowing streams with condensation. [Developed for application to laser isotope separation]

Description: An analytical model was developed to identify the basic phenomena present in the high temperature flow (2700/sup 0/K) of two gaseous coaxial streams. The one-dimensional model potentially has application for design of hardware and test conditions for conducting a laser isotope separation feasibility experiment. The processes of interest are those of coupled flow dynamics, liquid condensation of metal vapors, and gaseous diffusion. The stream tubes may initially consist of pure or combinations o… more

Laser isotope separation by selective excited state photochemistry. Annual progress report, March 31, 1976--February 28, 1977

Description: Experimental results are presented providing insight into the mechanisms of photochemical separation of Cd isotopes by selective excitation of ICl in the presence of halogenated olefins. The types of scrambling reactions that can be expected in isotope separation by scavenging are discussed along with strategies for minimizing such reactions. The experimental results are summarized and the reaction mechanisms are represented by graphic equations. (JRD)

D. C. electric field behavior of high lying states in atomic uranium

Description: The effects of D. C. electric fields on high lying Rydberg and valence states in atomic uranium have been studied. Results of measurements of Stark shifts, lifetime lengthening via l-mixing, critical fields for ionization, barrier tunneling, and the appearance of zero-field parity forbidden transitions are presented for atomic uranium along with the observation of field induced autoionization of valence states. 3 figs.

Calculation of multicomponent flows in the aerodynamic separation of uranium isotopes

Description: Equations governing gas flow containing uranium hexafluoride and an inert carrier have been developed for mixtures typical of those used in aerodynamic isotope separation. In this report these equations are solved for a simple separation device (two-dimensional channel with external force). The numerical solutions are compared with the results obtained from direct simulation.

NMIS with Imaging and Gamma Ray Spectrometry for Pu, HEU, HE and Other Materials

Description: The Nuclear Material Identification System (NMIS) has been under development at ORNL and the National Nuclear Security Administration (NNSA) Y-12 National Security Complex since 1984. In the mid-1990s, what is now the US Department of Energy (DOE) Office of Nuclear Verification (ONV) realized that it was a useful technology for future arms control treaty applications and supported further development of the system. In 2004, fast-neutron imaging was incorporated into the system. In 2007, the ONV… more

The Theory of Uranium Enrichment by the Gas Centrifuge

Description: Onsager's analysis of the hydrodynamics of fluid circulation in the boundary layer on the rotor wall of a gas centrifuge is reviewed. The description of the flow in the boundary layers on the top and bottom end caps due to Carrier and Maslen is summarized. The method developed by Wood and Morton of coupling the flow models in the rotor wall and end cap boundary layers to complete the hydrodynamic analysis of the centrifuge is presented. Mechanical and thermal methods of driving the internal gas… more

NDA SYSTEM RESPONSE MODELING AND ITS APPLICATION

Description: The Portsmouth gaseous diffusion plant (PORTS) is a uranium enrichment facility that was historically used to enrich uranium to levels that range from 2% to greater than 97%. The feed material for PORTS was obtained from the Paducah Gaseous Diffusion Plant (PGDP) that produced uranium in the form of UF6 that was enriched to about 1 to 2%. The enrichment process involves a multistage process by which gaseous UF{sub 6} passed through a diffusion barrier in each stage. The porous diffusion barrier… more

Characterization of Post-Cleaning Solids Samples from the 2H Evaporator Pot

Description: Samples retrieved from the 2H Evaporator Pot in October of 2003 were of a similar nature as previous materials. The bulk of the sample was comprised of a sodium aluminosilicate phase, cancrinite. The concentration of uranium in the evaporator solids,however, was very low:less than 0.1 percentage weight. The uranium enrichment was depleted as expected and measured 0.6 percent. These data agree with uranium contents generated during experimental testing. Additionally, the overall specific radionu… more

Supercritical Carbon Dioxide Ligands for Extracting Actinide Metal Ions from Porous Solids

Description: Numerous types of actinide-bearing waste materials are found throughout the DOE complex. Most of these wastes consist of large volumes of non-hazardous materials contaminated with relatively small quantities of actinide elements. Separation of these wastes into their inert and radioactive components would dramatically reduce the costs of stabilization and disposal. For example, the DOE is responsible for decontaminating concrete within 7000 surplus contaminated buildings. The best technology no… more
