Turbine-generator set development for power generation
The goal of this effort was to design, develop, and demonstrate an integrated turbine genset suitable for the power generation requirements of a hybrid automotive propulsion system. The result of this effort would have been prototype generator hardware including controllers for testing and evaluation by Allison Engine Company. The generator would have been coupled to a suitably sized and configured gas turbine engine, which would operate on a laboratory load bank. This effort could lead to extensive knowledge and design capability in the most efficient generator design for hybrid electric vehicle power generation and potentially to commercialization of these advanced technologies. Through the use of the high-speed turbines as a power source for the hybrid-electric vehicles, a significant reduction in nitrous oxides emissions would be achieved when compared to those of conventional gas powered vehicles.

FY 1996 cost savings by program
In September 1994 the DOE Richland Operations Office (RL) approved the FY 1995 multi-year baseline that included a cost estimate of $1.9 billion for FY 1996. However, Congress only appropriated $1.3 billion for that year. The shortfall of $600 million resulted in a significant challenge to accomplish the required workscope. Therefore, RL initiated an aggressive cost savings program to eliminate the shortfall by deleting workscope that was unnecessary and performing the remaining workscope more efficiently. RL initiated baseline planning actions (including deletions, deferrals, transfers, and additions) during the FY 1996 multi-year baseline development process to match workscope and anticipated funding and identified $205 million of workscope deletions. CFR (Contract Finance and Review Division) then reviewed over 200 cost baseline change requests during FY 1996 and documented an additional $95 million of FY 1996 cost savings. This included $73 million of workscope deletions and $22 million of efficiencies. Total savings as a result of FY 1996 initiatives, including baseline planning actions and current year initiatives, were $300 million. This report contains tables which enumerate the savings realized within each program at Hanford.

FY 1996 cost savings report
Cost savings are an integral part of Hanford site operations. Congressional actions towards establishing a balanced budget have resulted in reductions to funding for all federal agencies, including the Department of Energy (DOE) Environmental Management (EM) cleanup mission. In September 1994 the DOE Richland Operations Office (RL) approved the FY 1995 multi-year baseline that included a cost estimate of $1.9 billion for FY 1996. However, Congress only appropriated $1.3 billion for that year. The shortfall of $600 million resulted in a significant challenge to accomplish the required workscope.

Along the Texas Forts Trail
Access:
Use of this item is restricted to the UNT Community
The task of providing military defense for the Texas Frontier was never an easy one because the territory was claimed by some of the greatest querrilla fighters of all times—the Comanches, Kiowas, Apaches, and Lipans. Protecting a line running from the Red River southwest to El Paso was an impossible task, but following the Mexican War the federal government attempted to do so by establishing a line of forts. During the Civil War the forts were virtually abandoned and the Indians once again ruled the area. Following the war when the military began to restore the old forts, they found that the Indians no longer fought with bows and arrows but shouldered the latest firearms. With their new weapons the Indians were able to inflict tremendous destruction, bringing demands from settlers for more protection. In the summer of 1866 a new line of forts appeared through central Texas under the leadership of General Philip H. Sheridan, commander of federal forces in Louisiana and Texas. Guardians of a raw young land and focal points of high adventure, the old forts were indispensable in their day of service and it is fitting that they be preserved. In and around the forts and …

Integrated monitoring and surveillance system demonstration project: Phase I accomplishments
The authors present the results of the Integrated Monitoring and Surveillance System (IMSS) demonstration project Phase I efforts. The rationale behind IMSS development is reviewed and progress in each of the 5 basic tasks is detailed. Significant results include decisions to use Echelon LonWorks networking protocol and Microsoft Access for the data system needs, a preliminary design for the plutonium canning system glovebox, identification of facilities and materials available for the demonstration, determination of possibly affected facility documentation, and a preliminary list of available sensor technologies. Recently imposed changes in the overall project schedule and scope are also discussed and budgetary requirements for competition of Phase II presented. The results show that the IMSS demonstration project team has met and in many cases exceeded the commitments made for Phase I deliverables.

The MINOS long-baseline experiment at Fermilab.
The MINOS long-baseline experiment will search for neutrino oscillations by measuring an intense {nu}{sub {mu}} beam at the end of a 730 km flight path. The 10,000 ton MINOS far detector will utilize magnetized steel plates interleaved with track chambers to reconstruct event topologies and to measure the energies of the muons, hadrons and electromagnetic showers produced by neutrino interactions. The experiment is designed to detect {nu}{sub {mu}} {r_arrow} {nu}{sub {tau}} and {nu}{sub {mu}} {r_arrow} {nu}{sub e} oscillations with {Delta}m{sup 2} {ge} 0.001 eV{sup 2} and sin{sup 2}(2{theta}) {ge} 0.01. Any oscillation signal observed can be verified and studied by several independent tests: a near/far rate comparison, the NC/CC event ratio, the CC and NC event energy spectra, and the identification of electrons and {tau} leptons. The neutrino beam can be operated in both wide-band and narrow-band configurations, allowing the detailed study oscillation phenomena. The experiment is scheduled to begin operation in 2001.

KINETICS OF Mn-BASED SORBENTS FOR HOT COAL GAS DESULFURIZATION
Mixed manganese oxide sorbents have been investigated for high-temperature removal of hydrogen sulfide (the primary sulfur bearing compound) from hot coal gases. The sorbents were screened by thermodynamic equilibrium considerations for sulfidation. Preliminary experimental work using thermogravimetric analysis (TGA) indicated titania to be a superior substrate than alumina. Four formulations showing superior reactivity in a TGA were then tested in an ambient pressure fixed-bed reactor to determine steady state H 2 S concentrations, breakthrough times and effectiveness of the sorbent when subjected to cyclic sulfidation and regeneration testing. Eight tests were conducted with each test consisting of five cycles of sulfidation and regeneration. Sulfidation occurred at 600 o C using a simulated coal gas at an empty-bed space velocity of approximately 12,000 per hour. Manganese-based sorbents with molar ratios > 1:1 Mn:Substrate were effective in reducing the H 2 S concentration in simulated coal gases to less than 100 ppmv over five cycles. Actual breakthrough time for formulation C6-2-1100 was as high as 73% of breakthrough time based on wt% Mn in sorbent at 600 o C. Regeneration tests determined that loaded pellets can be essentially completely regenerated in an air/steam mixture at 750 o C with minimal sulfate formation. …

Test report for run-in acceptance testing of hydrogen mitigation retrieval Pump-3
This report will provide the findings of the demonstration test conducted on the Double-Shell Tank (DST) 241-SY-101 HMR Pump-3 in accordance with WHC-SDWM-TP-434 ``Test plan for run-in acceptance testing of hydrogen mitigation/retrieval pump-3`` at the 400 Area Maintenance and Storage Facility (MASF) building from 7 June 1996 through 30 July 1996 per work package 4A-96-92/W. The DST 241-SY-101 hydrogen mitigation retrieval Pump-3 is a 200-HP submersible electric driven pump that has been modified for use in the DST 241-SY-101 containing mixed waste located in the 200W area. The pump has a motor driven rotation mechanism that allows the pump column to rotate through 355{degree}. Prior to operation, pre-operational checks were performed which included loop calibration grooming and alignment of instruments, learning how plumb HMR-3 assembly hung in a vertical position and bump test of the motor to determine rotation direction. The pump was tested in the MASF Large Diameter Cleaning Vessel (LDCV) with process water at controlled temperatures and levels. In addition, the water temperature of the cooling water to the motor oil heat exchanger was recorded during testing. A 480-volt source powered a Variable Frequency Drive (VFD). The VFD powered the pump at various frequencies and voltages to control …

Project Hanford management contract quality assurance program implementation plan for nuclear facilities
During transition from the Westinghouse Hanford Company (WHC) Management and Operations (M and O) contract to the Fluor Daniel Hanford (FDH) Management and Integration (M and I) contract, existing WHC policies, procedures, and manuals were reviewed to determine which to adopt on an interim basis. Both WHC-SP-1131,Hanford Quality Assurance Program and Implementation Plan, and WHC-CM-4-2, Quality Assurance Manual, were adopted; however, it was recognized that revisions were required to address the functions and responsibilities of the Project Hanford Management Contract (PHMC). This Quality Assurance Program Implementation Plan for Nuclear Facilities (HNF-SP-1228) supersedes the implementation portion of WHC-SP-1 13 1, Rev. 1. The revised Quality Assurance (QA) Program is documented in the Project Hanford Quality Assurance Program Description (QAPD), HNF-MP-599. That document replaces the QA Program in WHC-SP-1131, Rev. 1. The scope of this document is limited to documenting the nuclear facilities managed by FDH and its Major Subcontractors (MSCS) and the status of the implementation of 10 CFR 830.120, Quality Assurance Requirements, at those facilities. Since the QA Program for the nuclear facilities is now documented in the QAPD, future updates of the information provided in this plan will be by letter. The layout of this plan is similar to …

Development and implementation of sensitivity coefficient equations for heat conduction problems
Three different methods are discussed for computing the sensitivity of the temperature field to changes in material properties and initial-boundary condition parameters for heat conduction problems. The most general method is to derive sensitivity equations by differentiating the energy equation with respect to the parameter of interest and numerically solving the resulting sensitivity equations. An example problem in which there are twelve parameters of interest is presented and the resulting sensitivity equations are derived. Numerical results are presented for thermal conductivity and volumetric heat capacity sensitivity coefficients for heat conduction in a 2-D orthotropic body. The numerical results are compared with the analytical solution to demonstrate that the numerical method is second order accurate as the mesh is refined spatially.

HIGH SO2 REMOVAL EFFICIENCY TESTING
This final report describes the results of performance tests at six full-scale wet lime- and limestone-reagent flue gas desulfurization (FGD) systems. The objective of these tests was to evaluate the effectiveness of low capital cost sulfur dioxide (SO{sub 2}) removal upgrades for existing FGD systems as an option for complying with the provisions of the Clean Air Act Amendments of 1990. The upgrade options tested at the limestone-reagent systems included the use of organic acid additives (dibasic acid (DBA) and/or sodium formate) as well as increased reagent ratio (higher excess limestone levels in the recirculating slurry solids) and absorber liquid-to-gas ratio. One system also tested operating at higher flue gas velocities to allow the existing FGD system to treat flue gas from an adjacent, unscrubbed unit. Upgrade options for the one lime-based system tested included increased absorber venturi pressure drop and increased sulfite concentration in the recirculating slurry liquor.
