324 and 325 Building hot cell cleanout program: Decontamination of C-Cell

Description: During FY 1989 the decontamination of C-Cell of Hanford's 324 Building was completed as part of the 324 and 325 Building Hot Cell Cleanout Program sponsored by the DOE Nuclear Energy's Surplus Facilities Management Program. The decontamination effort was completed using a series of remote and contact decontamination techniques. Initial radiation readings in C-Cell averaged 50 rad/hr and were reduced remotely to less than 200 mrad/hr using an alkaline foam cleaner followed by a 5000-psi water fl… more

The Active Personnel Dosimeter: Apfel Enterprises superheated drop detector

Description: The Active Personnel Dosimeter (APD) provides a digital readout of events caused by neutrons interacting with superheated liquid droplets. The droplets are suspended in a gel held in a replaceable cartridge. Upon neutron interaction, the superheated droplet vaporizes, forming a bubble. The sound produced in this process is recorded by transducers that sense the accompanying pressure pulse. The APD electronically discriminates against spurious noise and vibration. Studies with the production pro… more

Advanced spectroscopic analysis of coal surfaces during beneficiation

Description: Preliminary FTIR spectra are reported on coals undergoing flotation where enhanced recovery was achieved by ultrasonic or chemical treatments. The spectra of sonicated coals indicate that ultrasonic treatment (10 kHz Swen Sonic) reduces the surface oxidation of heavily oxidized coal. Spectra of chemically treated coal indicate that a higher mineral concentration is present on or near the surface of float coal suggesting that a slime might be present. Spectra are reported for coal-, mineral-, an… more

Ambiguities in the elastic scattering of 8 MeV neutrons from adjacent nuclei

Description: Ratios of the cross sections for elastic scattering of 8 MeV neutrons from adjacent nuclei are measured over the angular range {approx}20{degree} {minus} 160{degree} for the target pairs {sup 51}V/Cr, {sup 59}Co/{sup 58}Ni, Cu/Zn, {sup 89}Y/{sup 93}Nb, {sup 89}Y/Zr, {sup 93}Nb/Zr, In/Cd and {sup 209}Bi/Pb. The observed ratios vary from unity by as much as a factor of {approx}2 at some angles for the lighter target pairs. Approximately half the measured ratios are reasonably explained by a simpl… more

Analysis of the hydraulic data from the MI fracture zone at the Grimsel Rock Laboratory, Switzerland

Description: One of the major problems in analyzing flow and transport in fractured rock is that the flow may be largely confined to a poorly connected network of fractures. In order to overcome some of this problem, Lawrence Berkeley Laboratory (LBL) has been developing a new type of fracture hydrology model called an equivalent discontinuum model. In this model the authors represent the discontinuous nature of the problem through flow on a partially filled lattice. A key component in constructing an equiv… more

Analysis of tracer and thermal transients during reinjection

Description: This work studied tracer and thermal transients during reinjection in geothermal reserviors and developed a new technique which combines the results from interwell tracer tests and thermal injection-backflow tests to estimate the thermal breakthrough times. Tracer tests are essential to determine the degree of connectivity between the injection wells and the producing wells. To analyze the tracer return profiles quantitatively, we employed three mathematical models namely, the convection-disper… more

Aquifer Characterization at the General Motors Harrison Division Plant, Tuscaloosa, Alabama

Description: The General Motors corporation is studying the feasibility of aquifer thermal energy storage (ATES) for cooling purposes at its Harrison Division plant Tuscaloosa, Alabama. To determine the characteristics of the aquifer underlying the plant, the Pacific Northwest Laboratory (PNL) gathered information about the environment of the aquifer and conducted tests to determine the aquifer's transmissivity and flow. From these tests, calculated estimates of ground-water velocity and flow direction were… more

Aquifer Characterization at the Veterans Administration Hospital, Tuscaloosa, Alabama

Description: The Veterans Administration (VA) is studying the feasibility of aquifer thermal storage (ATES) at their Tuscaloosa, Alabama, facility. To determine the characteristics of the aquifer underlying the facility, the Pacific Northwest Laboratory gathered information about the environment of the aquifer and conducted tests to estimate the aquifer's transmissivity, ground-water flow direction, and velocity. Seven wells were drilled at the VA site. It was found that ground-water flow direction at the s… more

The ARIES tokamak reactor study

Description: The ARIES study is a community effort to develop several visions of tokamaks as fusion power reactors. The aims are to determine the potential economics, safety, and environmental features of a range of possible tokamak reactors, and to identify physics and technology areas with the highest leverage for achieving the best tokamak reactor. Three ARIES visions are planned, each having a different degree of extrapolation from the present data base in physics and technology. The ARIES-I design assu… more

B physics at the Z sup 0 pole

Description: The SLC has been running at SLAC since April, and more than 100 Z{sup 0} events have been reconstructed. Shortly the new European facility at CERN-LEP-will also turn on, and by the end of the year we anticipate that more than 10,000 Z{sup 0} events will have been registered by each of the four LEP detectors. Most of the experimental facilities at these two machines are equipped with excellent particle tracking and identification. Some have close-in tracking devices which will provide unparallel… more

The behavior of matter under nonequilibrium conditions: Fundamental aspects and applications

Description: As in the previous period, our work has been concerned with the study of the properties of nonequilibrium systems and especially with the mechanism of self-organization. As is well-known, the study of self-organization began with the investigation of hydrodynamical or chemical instabilities studied from the point of view of macroscopic physics. The main outcome is that nonequilibrium generates spatial correlations of macroscopic physics. The main outcome is that nonequilibrium generates spatial… more

Binary complex fragment emission and multifragmentation from very hot nuclei

Description: Complex fragments at low and intermediate energies originate mostly from the binary decay of a compound nucleus formed in either complete or incomplete fusion. With increasing bombarding energy incomplete fusion should terminate. Evidence of this occurrence is given. As the excitation energy increases, multifragment decay becomes prevalent. The sources of ternary and quaternary events, characterized in terms of their velocity and total charge, do not seem to differ from that of binary events. 9… more

The Breeding Blanket Interface (BBI) and the Tritium Systems Test Assembly (TSTA)

Description: The Tritium System Test Assembly (TSTA) project at Los Alamos National Laboratory is charged with developing and demonstrating the fusion fuel processing requirement for the magnetic fusion energy program. The key fusion fuel streams are the plasma exhaust and the blanket stream. At present, the technology under development at TSTA includes only the plasma exhaust. The blanket is a logical upgrade to TSTA. This possible upgrade is the subject of an ongoing study among LANL, JAERI, and Argonne N… more

Description: The Tritium Systems Test Assembly (TSTA) at Los Alamos is a full-scale facility dedicated to testing tritium processing for fusion reactors. We are involved in a study of adding a Breeder Blanket Interface (BBI) to the TSTA. The BBI is to test the processing required for the tritium output streams for the various fusion reactor breeder blankets. In the current phase of the study, we are evaluating the characteristics of the output from various breeding blankets types. Emphasis is placed on defi… more

A Broad View of Model Validation

Description: The safety assessment of a nuclear waste repository requires the use of models. Such models need to be validated to ensure, as much as possible, that they are a good representation of the actual processes occurring in the real system. In this paper we attempt to take a broad view by reviewing step by step the modeling process and bringing out the need to validating every step of this process. This model validation includes not only comparison of modeling results with data from selected experime… more
