Assessing the Feasibility of Renewable Energy Development and Energy Efficiency Deployment on Tribal Lands

The Keweenaw Bay Indian Community (KBIC) is committed to preserving our natural environment and reducing the amount of fossil fuels consumed while developing "green" business manufacturing jobs on tribal lands. The Tribe's Comprehensive Strategic Plan seeks to diversify the Tribal Economy through the creation of alternative energy businesses, such as wind, solar and bio-mass facilities while protecting the waters of Lake Superior, tribal inland lakes and streams. In addition, the Community desired to utilize clean/green energy resources to promote the self-sufficiency of the Tribal Nation. The objective of the study is to preserve our environment and maintain our cultural goals of using the resources of the land wisely. To reduce our consumption of fossil fuels, mercury and carbon dioxide emissions, which harm our water and land; we have decided to evaluate the opportunities of utilizing wind power. Preliminary projections show that we may eliminate pollution from our land in a cost effective manner. This study will evaluate wind capacity and our current energy consumption while projecting the feasibility of converting to wind power for operations at our major facilities. This project will study the feasibility of wind power at two locations for the purpose of reducing the Tribe's reliance upon …

Determination Of Reportable Radionuclides For DWPF Sludge Batch 7B (Macrobatch 9) (open access)

Determination Of Reportable Radionuclides For DWPF Sludge Batch 7B (Macrobatch 9)

The DWPF is receiving radioactive sludge slurry from HLW Tank 40. The radioactive sludge slurry in Tank 40 is a blend of the heel from Sludge Batch 7a (SB7a) and Sludge Batch 7b (SB7b) that was transferred to Tank 40 from Tank 51. The blend of sludge in Tank 40 is also referred to as Macrobatch 9 (MB9). This report develops the list of reportable radionuclides and associated activities as a function of time. Twenty-seven radionuclides have been identified as reportable for DWPF SB7b. Each of these radionuclides has a half-life greater than ten years and contributes more than 0.01% of the radioactivity on a Curie basis at some point from production through the 1100 year period between 2015 and 3115. For SB7b, all of the radionuclides in the Design Basis glass are reportable except for three radionuclides: Pd-107, Cs-135, and Th-230. At no time during the 1100- year period between 2015 and 3115 did any of these three radionuclides contribute to more than 0.01% of the radioactivity on a Curie basis. The radionuclide measurements made for SB7b are the most extensive conducted to date. Some method development/refinement occurred during the conduct of these measurements, leading to lower detection limits …

Ecosystem-Atmosphere Exchange of Carbon, Water and Energy over a Mixed Deciduous Forest in the Midwest (open access)

Ecosystem-Atmosphere Exchange of Carbon, Water and Energy over a Mixed Deciduous Forest in the Midwest

During the project period we continued to conduct long-term (multi-year) measurements, analysis, and modeling of energy and mass exchange in and over a deciduous forest in the Midwestern United States, to enhance the understanding of soil-vegetation-atmosphere exchange of carbon. At the time when this report was prepared, results from nine years of measurements (1998 - 2006) of above canopy CO2 and energy fluxes at the AmeriFlux site in the Morgan-Monroe State Forest, Indiana, USA (see Table 1), were available on the Fluxnet database, and the hourly CO2 fluxes for 2007 are presented here (see Figure 1). The annual sequestration of atmospheric carbon by the forest is determined to be between 240 and 420 g C m-2 a-1 for the first ten years. These estimates are based on eddy covariance measurements above the forest, with a gap-filling scheme based on soil temperature and photosynthetically active radiation. Data gaps result from missing data or measurements that were rejected in qua)lity control (e.g., during calm nights). Complementary measurements of ecological variables (i.e. inventory method), provided an alternative method to quantify net carbon uptake by the forest, partition carbon allocation in each ecosystem components, and reduce uncertainty on annual net ecosystem productivity (NEP). Biometric …

Increase Jc by Improving the Array of Nb3Sn strands for Fusion Application (open access)

Increase Jc by Improving the Array of Nb3Sn strands for Fusion Application

During Phase I, our efforts were focusing on improving the array of subelement in the tube type strands by hardening the Sn core and the subelement matrix to effectively increase the Jc of the strands. Below is a summary of the results. 1) We were unsuccessful in improving the array using a Cu-Sn matrix approach. 2) We slightly improved the array using Sn with 1.5at%Ti doped core, and a 217-subelement restacked strand was made and drawn down without any breakage. 3) We greatly improved the array using the Glidcop Al-15 to replace the pure Cu sheath in the subelement, and a 217-subelement restacked strand was made and drawn down. Both strands have very good drawability and the array showed good improvement. 4) We also improved the array using improved wire drawing techniques using Hyper Tech’s new caterpillar wire drawing machines to enable straight wire drawing for the entire wire drawing process. 5) The 919-subelement restack strand shows its non-Cu Jc over 2100 A/mm2 at 12 T/4.2 K and AC loss of 508 mJ/cm3.

Increasing the Jc of Tube-Type Nb3Sn Strands (open access)

Increasing the Jc of Tube-Type Nb3Sn Strands

In this Phase I, we successfully made strands with better Cu/Sn ratio to reduce the coarse Nb3Sn grain region, thereby providing the potential of increasing the non-Cu Jc in the Phase II and scaling up to 2” billets with 331 subelements. In order to improve the strand’s high field properties, we successfully doped low amount of Ti in the subelements and made a 217-subelement wire which has been drawn down to 0.7 mm without any breakage. This strand gave subelement size of 35 µm. We will scale up the Ti-doped billet to 271-subelement in 1.5” billet in this proposed Phase II. The hexagonal shaped subelements with round Nb-Sn have been developed for a 61-subelement restack. Thus the results indicated that for 217-subelement restack in a 2” billet we have the potential to draw down this type of construction without problems while maintaining a good array to react more Nb to get higher non-Cu Jc in the Phase II.

Integrated Genome-Based Studies of Shewanella Ecophysiology (open access)

Integrated Genome-Based Studies of Shewanella Ecophysiology

Integration of bioinformatics and experimental techniques was applied to mapping and characterization of the key components (pathways, enzymes, transporters, regulators) of the core metabolic machinery in Shewanella oneidensis and related species with main focus was on metabolic and regulatory pathways involved in utilization of various carbon and energy sources. Among the main accomplishments reflected in ten joint publications with other participants of Shewanella Federation are: (i) A systems-level reconstruction of carbohydrate utilization pathways in the genus of Shewanella (19 species). This analysis yielded reconstruction of 18 sugar utilization pathways including 10 novel pathway variants and prediction of > 60 novel protein families of enzymes, transporters and regulators involved in these pathways. Selected functional predictions were verified by focused biochemical and genetic experiments. Observed growth phenotypes were consistent with bioinformatic predictions providing strong validation of the technology and (ii) Global genomic reconstruction of transcriptional regulons in 16 Shewanella genomes. The inferred regulatory network includes 82 transcription factors, 8 riboswitches and 6 translational attenuators. Of those, 45 regulons were inferred directly from the genome context analysis, whereas others were propagated from previously characterized regulons in other species. Selected regulatory predictions were experimentally tested. Integration of this analysis with microarray data revealed overall …

Reduce Nb3Sn Strand Deformation when Fabricating High Jc Rutherford Cables (open access)

Reduce Nb3Sn Strand Deformation when Fabricating High Jc Rutherford Cables

During Phase I, our efforts were to reduce subelements deformation when fabricating Nb3Sn Rutherford cables. Our first focus is on 217-sublement tube type strand. We successfully made a few billets in ¾” OD tube with different Cu spacing between subelements, and supplied the strands to Fermi Lab for cabling. Through the rolling test characterization, these types of strands did not have enough bonding between subelements to withstand the deformation. We saw copper cracking between subelements in the deformed strands. We scaled up the billet from ¾” OD to 1.5” OD, and made two billets. This greatly improves the bonding. There is no copper cracking in the deformed strands when we scaled up the diameter of the billets. Fermi Lab successfully made cables using one of this improved strands. In their cables, no Cu cracking and no filament bridging occurred. We also successfully made a couple of billets with hex OD and round ID subelements for 61-subelement restack. Due to the lack of bonding, we could not judge its cabling property properly. But we know through this experiment, we could keep the Nb round, once we select the proper Cu spacing.

Transition metal complexes of oxazolinylboranes and cyclopentadienyl-bis(oxazolinyl)borates: Catalysts for asymmetric olefin hydroamination and acceptorless alcohol decarbonylation (open access)

Transition metal complexes of oxazolinylboranes and cyclopentadienyl-bis(oxazolinyl)borates: Catalysts for asymmetric olefin hydroamination and acceptorless alcohol decarbonylation

The research presented and discussed in this dissertation involves the synthesis of transition metal complexes of oxazolinylboranes and cyclopentadienyl-bis(oxazolinyl)borates, and their application in catalytic enantioselective olefin hydroamination and acceptorless alcohol decarbonylation. Neutral oxazolinylboranes are excellent synthetic intermediates for preparing new borate ligands and also developing organometallic complexes. Achiral and optically active bis(oxazolinyl)phenylboranes are synthesized by reaction of 2-lithio-2-oxazolide and 0.50 equiv of dichlorophenylborane. These bis(oxazolinyl)phenylboranes are oligomeric species in solid state resulting from the coordination of an oxazoline to the boron center of another borane monomer. The treatment of chiral bis(oxazolinyl)phenylboranes with sodium cyclopentadienide provide optically active cyclopentadienyl-bis(oxazolinyl)borates H[PhB(C{sub 5}H{sub 5})(Ox{sup R}){sub 2}] [Ox{sup R} = Ox{sup 4S-iPr,Me2}, Ox{sup 4R-iPr,Me2}, Ox{sup 4S-tBu]}. These optically active proligands react with an equivalent of M(NMe{sub 2}){sub 4} (M = Ti, Zr, Hf) to afford corresponding cyclopentadienyl-bis(oxazolinyl)borato group 4 complexes {PhB(C{sub 5}H{sub 4})(Ox{sup R}){sub 2}}M(NMe{sub 2}){sub 2} in high yields. These group 4 compounds catalyze cyclization of aminoalkenes at room temperature or below, providing pyrrolidine, piperidine, and azepane with enantiomeric excesses up to 99%. Our mechanistic investigations suggest a non-insertive mechanism involving concerted C−N/C−H bond formation in the turnover limiting step of the catalytic cycle. Among cyclopentadienyl-bis(oxazolinyl)borato group 4 catalysts, the zirconium complex {PhB(C{sub …
