UTSI/CFFF MHD PROGRAM COMPLETION AND RELATED ACTIVITY

Description: The Discharge Monitoring Reports (DMRs) for July, August and September, 2003, were prepared and submitted to the Tennessee Department of Environment and Conservation (TDEC). Discussions were held during July with our environmental consulting firm (TVG Environmental) and the Tennessee Department of Environment and Conservation (TDEC) about the groundwater testing program for the CFFF. Both TVG and TDEC advised that we continue with the semiannual sampling schedule for at least the next 6 months to a year. A relatively new category titled Site-Specific Impaired Classification is being considered for the CFFF, but the documentation requirements are expected to be extensive and expensive. The next sampling event will be contracted for in November 2003. In addition to regular monthly report to TDEC, a regional inspector from TDEC came by to inspect the CFFF for compliance with the water discharge permit. He took a short tour of the facility and subsequently issued a statement that the CFFF was in compliance with the permit. TVG Environmental, Inc. of Nashville was requested to provide a cost quote to perform the next scheduled groundwater sampling event for the CFFF. They quoted the same per-event cost as the two previous sampling events. TVG was awarded the contract and the next scheduled semiannual sampling event will occur in mid-November.

UTSI/CFFF MHD PROGRAM COMPLETION AND RELATED ACTIVITY

Description: The Discharge Monitoring Reports (DMRs) for October, November and December, 2003, were prepared and submitted to the Tennessee Department of Environment and Conservation (TDEC). TVG Environmental, Inc. carried out the scheduled groundwater well sampling on November 17, 2003. The CFFF is currently on a semi-annual testing program required by the Tennessee Department of Environment and Conservation. TVG Environmental conducted this semi-annual sampling event for five groundwater wells adjacent to the CFFF. The semi-annual Groundwater Monitoring Report (dated December 17, 2003) from TVG Environmental was received in late December, 2003. The report was noted to have a couple of typographical errors and therefore, it was returned to TVG for correction. The corrected report will be forwarded to DOE in January 2004, as soon as it is received.

UTSI/CFFF MHD PROGRAM COMPLETION AND RELATED ACTIVITY

Description: The Discharge Monitoring Reports (DMRs) for the CFFF for December 2003, January 2004 and February 2004 were prepared and submitted to the Tennessee Department of Environment and Conservation. In March 2004, the TDEC issued a revised Discharge Permit for the CFFF that will allow yearly rather than monthly DMRs. The new permit goes into effect on April 1, 2004. Groundwater testing and reporting to TDEC is required on a semi-annual basis. A sampling event took place in November 2003 and the report submitted in December. Due to typographical errors in the report it was reissued in January 2004. Reportable amounts of controlled water pollutants continue to be found in the groundwater well samples. For the last two years groundwater sampling has been conducted by TVG Environmental, Inc. of Nashville, TN. Quantum Environmental and Engineering Services of Knoxville, TN was recently awarded the state contract for environmental services, and they were contacted about providing this service for the CFFF for calendar year 2004. A purchase order was placed with Quantum in March, but was later canceled due to a pricing conflict. The May sampling event will be conducted by TVG Environmental, and bids will be solicited for future environmental services.

Parameters affecting nitrogen oxides in a Coal-Fired Flow Facility system

Description: The unusually high temperature in the primary combustor of the Coal-Fired Magnetohydrodynamics (MHD) power generation system causes much higher nitrogen oxides (NO{sub x}) to be produced than in a conventional coal fired generation system. In order to lower the NO{sub x} concentration to an acceptable level, it is important to know how parameters of the MM power generation system affect the NO{sub x} concentration. This thesis investigates those effects in the Coal-Fired Flow Facility (CFFF) at the University of Tennessee Space Institute under the contract of US Department Of Energy (DOE). With thermodynamic and kinetic computer codes, the theoretical studies were carried out on the parameters of the CFFF system. The results gathered from the computer codes were analyzed and compared with the experimental data collected during the LMF5J test. The thermodynamic and kinetic codes together modeled the NO.{sub x} behavior with reasonable accuracy while some inconsistencies happened at the secondary combustor inlet.

High performance materials in coal conversion utilization. Final report, October 1, 1993--September 30, 1996

Description: This report describes the research conducted at the University of Tennessee Space Institute on high performance materials for use in corrosive environments. The work was supported by a US Department of Energy University Coal Research grant. Particular attention was given to the silicon carbide particulate reinforced alumina matrix ceramic composite manufactured by Lanxide Corporation as a potential tubular component in a coal-fired recuperative high-temperature air heater. Extensive testing was performed to determine the high temperature corrosion effects on the strength of the material. A computer modeling of the corrosion process was attempted but the problem proved to be too complex and was not successful. To simplify the situation, a computer model was successfully produced showing the corrosion thermodynamics involved on a monolithic ceramic under the High Performance Power System (HIPPS) conditions (see Appendix A). To seal the material surface and thus protect the silicon carbide particulate from corrosive attack, a dense non porous alumina coating was applied to the material surface. The coating was induced by a defocused carbon dioxide laser beam. High temperature corrosion and strength tests proved the effectiveness of the coating. The carbon dioxide laser was also used to successfully join two pieces of the Lanxide material, however, resources did not allow for the testing of the resulting joint.

Environmental remediation preservation of the facility continued. Government property has been transferred to UTSI as owner which frees up many items for proper disposal. Actions are underway to dispose of other wastes, and control pests and water at the DOE CFFF. Only one high temperature superconductivity project is active under Task 6. Under the particular Subtask 6.02, samples of nickel obtained from Plastronics, Inc. were coated with the LAO precursor solution. These coated samples have been characterized using the x-ray diffraction unit, and the results from the x-ray diffraction characterizations were further analyzed using a statistical program to develop multi-regression coefficients. Based on these regression coefficients, the variables that have significant effect on the coating of LAO over nickel substrate have been identified. A Master of Science thesis was prepared describing these findings and it will be defended in front of the committee members during July, 2000.
