Mercury in shallow Savannah River Plant soil

Description: Soil concentrations of adsorbed mercury at 999 sites at the Savannah River Plant (SRP) were determined by Microseeps Limited of Indianola, PA. The sites were in and around the 643-C Burial Ground, at the Savannah River Swamp adjacent to TNX Area, and at a background area. The Burial Ground was chosen as a test site because of a history of disposal of radioactive mercury there prior to 1968. Extremely low traces of mercury have been detected in the water table beneath the Burial Ground. Although… more

Mathematical modeling and economic analysis of membrane separation of hydrogen from gasifier synthesis gas. Mathematical modeling topical report

Description: Investigators are studying hydrogen purification by membrane technology as a means to make the coal-to-hydrogen route economically attractive. To allow prediction of membrane performance and to facilitate comparisons between membrane and other technologies (cryogenic distillation, pressure swing adsorption), they developed a mathematical model to describe the permeation process inside a membrane module. The results of this model were compared with available experimental data (separation of CO{s… more

Community emergency response to nuclear power plant accidents: A selected and partially annotated bibliography

Description: The role of responding to emergencies at nuclear power plants is often considered the responsibility of the personnel onsite. This is true for most, if not all, of the incidents that may happen during the course of the plant`s operating lifetime. There is however, the possibility of a major accident occurring at anytime. Major nuclear accidents at Chernobyl and Three Mile Island have taught their respective countries and communities a significant lesson in local emergency preparedness and respo… more

Development of a retrofit coal combustor for industrial applications, (Phase 1-A). Technical progress report, July--September 1988

Description: During this past quarter, two tandem-fired pulse combustors were designed to fire at a nominal rate of 3.5 to 5.5 MMBtu/hr under continuation of Phase I work on DOE project DE-AC22-87PC79654. In prior work, MTCI demonstrated the operation of a 1--2 MMBtu/h coal-fired tandem pulse combustor that is intended for small industrial applications. These component tests emphasized verification of key design issues such as combustor coupling, slag rejection, and staged air addition. The current work, wh… more

Sorption properties of carbon-14 on Savannah River Plant soil

Description: Batch experiments performed using {sup 14}C, Savannah River Plant (SRP) soil, and SRP burial ground groundwater indicate that the distribution coefficient, or K{sub d}, for {sup 14}C in the form of carbonates is typically 2 ml/g after 7 hours of equilibration and 55 ml/g after 72 hours. These results were obtained for samples containing {sup 14}C concentrations ranging from 4.2 nCi/ml up to 40.9 nCi/ml. For comparison the concentration of {sup 14}C in the sump leachate of the defense waste lysi… more

Impact of Redd Loss at Vernita Bar on Hanford Reach Chinook Salmon Production: Final Report 1988.

Description: This report describes the effect on chinook salmon production within the Hanford Reach of redd loss at Vernita Bar. The current target escapement of 40,000 chinook past McNary dam has no real biological justification because the wrong data were used in the analysis and the methods used are now known to be very unreliable for the type of data available. The escapement that maximizes MSY may be lower than 40,000, or much higher, and reliable estimates of optimum escapement are unlikely to be avai… more

Reentry response of the light weight radioisotope heater unit resulting from a Venus-Earth-Earth Gravity Assist maneuver accident

Description: Reentry analyses consisting of ablation response, thermal response and thermal stress response have been conducted on the Light Weight Radioisotope Heater Unit for Galileo/VEEGA reentry conditions. Sequential ablation analyses of the LWRHU aeroshell, the fuel clad, and the fuel pellet have been conducted in reentry regimes where the aeroshell has been deemed to fail. The failure criterion for ablation is assumed to be recession corresponding to 50% of the wall thickness (the design criterion re… more

Preliminary studies of an infrared free-electron laser oscillator at the ATF(BNL)

Description: In this report, I present results of a theoretical 1-D model discussed by G. Dattoli, A. Reniere and myself. The validity of a steady-state analysis is discussed and some estimates are given of the effects introduced by the ''lethargy'' of the laser pulse due to the finite length of the e/sup /minus// pulse. Also, I present analytical expressions for the laser pulse in terms of supermodes (wave-packets of cavity modes), their evolution, physical width as well as the associated frequency spectru… more

3-D numerical analysis of a high-gain free-electron laser

Description: We present a novel approach to the 3-dimensional high-gain free- electron laser amplifier problem. The method allows us to write the laser field as an integral equation which can be efficiently and accurately evaluated on a small computer. The model is general enough to allow the inclusion of various initial electron beam distributions to study the gain reduction mechanism and its dependence on the physical parameters. 16 refs., 8 figs., 1 tab.
