24 Hour pumping test of production well 905-120P (open access)

24 Hour pumping test of production well 905-120P

As part of the Savannah River Site (SRS) Aquifer Characterization Program, the Environmental Sciences Section (ESS) of the Savannah River Laboratory (SRL) is attempting to determine the water transmitting characteristics of the different aquifer units underlying the SRS by conducting single well pumping tests on wells installed as part of the SRS Baseline Hydrogeologic Investigation. In April 1990, while performing the single well pumping test, an opportunity became available to collect data on aquifer properties utilizing a production well and observation wells. At this time the US Army Corps of Engineers (COE) was completing a new production well (well 905-120P) in P-Area. This well, located in close proximity to well cluster P-24, was to undergo a 24-hour performance test by the COE. ESS arranged with the subcontractor working on the Single Well pumping Test project. Dames Moore, to instrument the appropriate observation wells and to coordinate data collection with the COE.

1988 Hanford riverbank springs characterization report (open access)

1988 Hanford riverbank springs characterization report

This reports presents the results of a special study undertaken to characterize the riverbank springs (i.e., ground-water seepage) entering the Columbia River along the Hanford Site. Radiological and nonradiological analyses were performed. River water samples were also analyzed from upstream and downstream of the Site as well as from the immediate vicinity of the springs. In addition, irrigation return water and spring water entering the river along the shoreline opposite Hanford were analyzed. Hanford-origin contaminants were detected in spring water entering the Columbia River along the Hanford Site. The type and concentrations of contaminants in the spring water were similar to those known to exist in the ground water near the river. The location and extent of the contaminated discharges compared favorably with recent ground-water reports and predictions. Spring discharge volumes remain very small relative to the flow of the Columbia. Downstream river sampling demonstrates the impact of ground-water discharges to be minimal, and negligible in most cases. Radionuclide concentrations were below US Department of Energy Derived Concentration Guides (DCGs) with the exception {sup 90}Sr near the 100-N Area. Tritium, while below the DCG, was detected at concentrations above the US Environmental Protection Agency drinking water standards in several springs. …

1990 update for the applications guide to pedestrian SNM (special nuclear material) monitors (open access)

1990 update for the applications guide to pedestrian SNM (special nuclear material) monitors

The physical principles of special nuclear material (SNM) monitoring have not changed in the five years since the writing of the Los Alamos report, An Applications Guide to Pedestrian SNM Monitors (AL-10633-MS).'' However, during those years, there has been evidence for the start of significant change in the practice of SNM monitoring. Recently revised Department of Energy orders allow flexibility in selecting material-control measures by addressing both abrupt and protracted theft or diversion of SNM and by grading the material according to its attractiveness. Other new guideline on how to apply, test, and maintain SNM monitors and metal detectors are becoming available from the American Society for Testing and Materials. But perhaps the most noticeable change to the Applications Guide is in Part 3, the catalog of commercial pedestrian SNM monitors, where many obsolete entries have been replaced by new monitors. This update for the Applications Guide catalogs new pedestrian SNM monitors and discusses what is new and what is changing in the practice of SNM monitoring. 31 refs., 11 figs.

A 2D electrostatic PIC code for the Mark III Hypercube (open access)

A 2D electrostatic PIC code for the Mark III Hypercube

We have implemented a 2D electrostastic plasma particle in cell (PIC) simulation code on the Caltech/JPL Mark IIIfp Hypercube. The code simulates plasma effects by evolving in time the trajectories of thousands to millions of charged particles subject to their self-consistent fields. Each particle`s position and velocity is advanced in time using a leap frog method for integrating Newton`s equations of motion in electric and magnetic fields. The electric field due to these moving charged particles is calculated on a spatial grid at each time by solving Poisson`s equation in Fourier space. These two tasks represent the largest part of the computation. To obtain efficient operation on a distributed memory parallel computer, we are using the General Concurrent PIC (GCPIC) algorithm previously developed for a 1D parallel PIC code.

Access and Use of Information Resources in Assessing Health Risks From Chemical Exposure: Proceedings (open access)

Access and Use of Information Resources in Assessing Health Risks From Chemical Exposure: Proceedings

Health risk assessment is based on access to comprehensive information about potentially hazardous agents in question. Relevant information is scattered throughout the literature, and often is not readily accessible. To be useful in assessment efforts, emerging scientific findings, risk assess parameters, and associated data must be compiled and evaluated systemically. The US Environmental Protection Agency (EPA) and Oak Ridge National Laboratory (ORNL) are among the federal agencies heavily involved in this effort. This symposium was a direct response by EPA and ORNL to the expressed needs of individuals involved in assessing risks from chemical exposure. In an effort to examine the state of the risk assessment process, the availability of toxicological information, and the future development and transfer of this information, the symposium provided an excellent cadre of speakers and participants from state and federal agencies, academia and research laboratories to address these topics. This stimulating and productive gathering discussed concerns associated with (1) environmental contamination by chemicals; (2) laws regulating chemicals; (3) information needs and resources; (4) applications; (5) challenges and priorities; and (6)future issues. Individual reports are processed separately for the data bases.

[The Activation and Decomposition of Alkanes on Group VIII Transition Metal Surfaces: Dynamics, Kinetics and Spectroscopy]. Progress Report

Significant progress has been achieved in a number of areas with the support of this Department of Energy grant which began on July 1, 1989. We have quantified experimentally the kinetics of the initial (low-coverage) alkane activation reaction, i.e., alkane {yields} alkyl + hydrogen adatom, for the following systems: (1) C{sub 2}H{sub 6} on Ir(110)-(1{times}2), and (2) CH{sub 4}, CD{sub 4}, C{sub 2}H{sub 6} and C{sub 2}D{sub 6} on Pt(110)-(1{times}2). In addition, we have employed dynamic Monte Carlo simulations to study two important aspects of surface reactivity, namely, reactant segregation during a steady-state surface reaction, and the compensation effect in a transient surface reaction. Experimentally determined values of the initial adsorption probability of ethane on Ir(110)(1{times}2) were employed to probe the dynamics of the interaction. Experimentally determined values of the initial trapping probability {zeta}{sub 0} of ethane into a physically adsorbed state at T{sub s} = 77 K as a function of E{sub i} and {Theta}{sub i} and experimentally determined values of the initial probability of dissociative chemisorption P{sub r} as a function of E{sub i}, {Theta}{sub i} and T{sub s} were obtained.

Adaptation of the IBM ECR (electric cantilever robot) robot to plutonium processing applications (open access)

Adaptation of the IBM ECR (electric cantilever robot) robot to plutonium processing applications

The changing regulatory climate in the US is adding increasing incentive to reduce operator dose and TRU waste for DOE plutonium processing operations. To help achieve that goal the authors have begun adapting a small commercial overhead gantry robot, the IBM electric cantilever robot (ECR), to plutonium processing applications. Steps are being taken to harden this robot to withstand the dry, often abrasive, environment within a plutonium glove box and to protect the electronic components against alpha radiation. A mock-up processing system for the reduction of the oxide to a metal was prepared and successfully demonstrated. Design of a working prototype is now underway using the results of this mock-up study. 7 figs., 4 tabs.

Adapting an x-ray/debris shield to the cascade ICF power plant: Neutronics issues (open access)

Adapting an x-ray/debris shield to the cascade ICF power plant: Neutronics issues

A neutronics analysis has been carried out to determine the effects on the Cascade ICF reactor concept of adding a solid-lithium x-ray and debris shield to each ICF capsule. Results indicate that tritium breeding in LiAlO{sub 2} is possible with a modest isotopic enhancement in {sup 6}Li (to 15%). The shallow-burial index is greater than 1 (indicating that deep burial may be required) if the blanket is kept in the reactor for more than 2.5 yr. Nine percent of the total thermal power is unrecoverable. Parts of the chamber wall may require replacement once during the reactor life due to radiation damage. Part of the SiC chamber end cap must be replaced annually. The reactor may not require any nuclear-grade construction. 20 refs., 4 figs., 3 tabs.

Advanced combustion system for industrial boilers. Phase 2, Quarterly technical progress report, April--June 1990 (open access)

Advanced combustion system for industrial boilers. Phase 2, Quarterly technical progress report, April--June 1990

(1) A ZrO{sub 2} oxygen sensor was calibrated successfully over the concentration range from 0 to 21 percent O{sub 2} at temperatures from ambient to 400{degrees}F. This inexpensive automotive sensor provides 8 signal which will be used to monitor and automatically control combustion conditions to maintain consistently high combustion efficiency combined with low NO{sub x} emissions; (2) An improved burner was designed and fabricated with an initial ``stage`` which functions as a coal-eductor/coal-air mixer. Now coal can be transported in dense phase to the burner without pressurizing the coal-storage hopper which had approximately a four-hour capacity. This permits refilling the hopper during periods of continuous operation of the boiler as required for commercial use; (3) The improved burner produced the highest boiler efficiency to date. Carbon burnout improved to 98.9 Percent, compared to about 97 percent during Phase I testing for the same Upper Elkhorn No. 3 coal with 2.7% ash. We expect to exceed 99% Combustion efficiency with all of the test coals during more optimized future testing; and (4) Although the new burner proved to be very efficient, emissions of NO{sub x} were higher than those observed during Phase I testing. The new-burner design was modified. Capability for …
