Activity Based Startup Plan for Prototype Vertical Denitration Calciner

Description: Testing activities on the Prototype Vertical Denitration Calciner at PFP were suspended in January 1997 due to the hold on fissile material handling in the facility. The restart of testing activities will require a review through an activity based startup process based upon Integrated Safety Management (ISM) principles to verify readiness. The Activity Based Startup Plan has been developed for this process.

AISI/DOE Advanced Process Control Program Vol. 5 of 6: Phase Measurement of Galvanneal

Description: Augmentation of the internal software of a commercial X-ray fluorescence gauge is shown to enable the instrument to extend its continuous on-line real-time measurements of a galvanneal coating's total elemental content to encompass similar measurements of the relative thickness of the coating's three principal metallurgical phases. The mathematical structure of this software augmentation is derived from the theory of neural networks. The performance of the augmented gauge is validated by compar… more

Analytical studies of top-up safety at the Advanced Photon Source.

Description: The Advanced Photon source (APS) is a 7 GeV, third-generation synchrotron radiation source. To provide more stable beam for users, they are pursuing a new operating mode called top-up. In this mode, the beam current is not allowed to decay as it normally would, but instead is maintained at a high level through frequent injection. A safety question with top-up mode is, during injection with photon shutters open, can injected beam ever exit a photon beamline? This might happen, for example, due t… more

Application of statistical methods for analyzing the relationship between casting distortion, mold filling, and interfacial heat transfer in sand molds

Description: This report presents a statistical method of evaluating geometric tolerances of casting products using point cloud data generated by coordinate measuring machine (CMM) process. The focus of this report is to present a statistical-based approach to evaluate the differences in dimensional and form variations or tolerances of casting products as affected by casting gating system, molding material, casting thickness, and casting orientation at the mold-metal interface. Form parameters such as flatn… more

Automated Sample collection and Analysis unit

Description: Autoramp is an atmospheric radionuclide collection and analysis unit designed for unattended operation. A large volume of air passes through one of 31 filter cartridges which is then moved from a sampling chamber and past a bar code reader, to a shielded enclosure. The collected dust-borne radionuclides are counted with a high resolution germanium gamma-ray detector. An analysis is made and the results are transmitted to a central station that can also remotely control the unit.

Automation and integration of multiplexed on-line sample preparation with capillary electrophoresis for DNA sequencing

Description: The purpose of this research is to develop a multiplexed sample processing system in conjunction with multiplexed capillary electrophoresis for high-throughput DNA sequencing. The concept from DNA template to called bases was first demonstrated with a manually operated single capillary system. Later, an automated microfluidic system with 8 channels based on the same principle was successfully constructed. The instrument automatically processes 8 templates through reaction, purification, denatur… more

A benthic carbon budget for the continental slope off Cape Hatteras, N.C.

Description: The continental slope off Cape Hatteras, N.C. from approximately 36{degree} 00 minutes N to 35{degree} 20 minutes N is a region of relatively rapid sediment accumulation, organic matter deposition and subsequent remineralization. The measured fluxes are the highest reported for the slope off the eastern US Sediment accumulation rates range from 40 to 140 cm ky{sup -1}. Organic carbon deposition rates range from 3.5 to 7.4 moles C m{sup -2} yr{sup -1}. The areal coverage of this ''depocenter'' i… more

Bubbleless gas transfer technology for the in situ remediation of chlorinated hydrocarbons

Description: The primary objective of this project is to demonstrate the ability of hydrogen to supply reducing equivalents for the reductive dehalogenation of perchloroethylene (PCE). This objective will be accomplished by two types of activities. First, laboratory experiments will compare the kinetics of hydrogen-mediated dehalogenation with natural routes of loss (hydrolysis and natural attenuation). Secondly, bench-scale column experiments will be performed to demonstrate hydrogen-mediated reductive deh… more
