Fort McDowell Indian Community Water Settlement (Yavapai Nation)

Settlement: Fort McDowell Indian Community Water Settlement (Jan. 15, 1993) Parties: Fort McDowell Indian Community, Yavapai Nation, Arizona, US, Salt River Valley Water Users Association, Salt River Project Agricultural Improvement and Power District, Roosevelt Water Conservation District, Chandler, Glendale, Mesa, Phoenix, Scottsdale, Tempe, Gilbert, and Central AZ Water Conservation District. Overall plan is to find enough water to irrigate 4,000 acres with a duty of 4.5 a/f/y and support 18,350 acres with a duty of 1 a/f/y. of urban development. With an exception for the Verde River Spill Water, total diversion (all from above Granite Reef Dam) is limited to 36,350 a/f/y. Diversions by Phoenix will not count against this total. 7,060 a/f/y will be controlled by the Kent, 6,730 a/f/y (delivered at 50 percent normal cost and phased in over five years) by the Salt River Project Agricultural Improvement and Power District, 3,200 a/f/y by the Roosevelt Water Conservation District, 4,300 a/f/y from the Central AZ Project, and 13,933 a/f/y from the Harquahala Irrigation District. In times of shortage, water will be released from Verde River reservoirs to first satisfy the Kent, and then those rights of the Tribe and Phoenix. The Tribe\u27s maximum diversion right is slightly greater than its entitlement to agreed-upon returns. Tribe shall file its water usage report annually with the Gila River Adjudication. Tribe receives 3,000 a/f of storage space behind Bartlett and Horseshoe dams for more effective use of Kent waters. 6,730 a/f of Salt River Project stored water is available for a specific area. Tribe waives all other water within and without boundaries of reservation. Tribe shall lease 4,300 a/f to Phoenix for 99 years starting Jan. 1, 2001. It\u27s estimated that USA will pay $36M, AZ$2M, Phoenix $5M and the Tribe$1M.

Damage to Macor glass-ceramic from high-dose 14 MeV neutrons

Macor machinable glass-ceramic was irradiated to fluences up to 1 {times} 10{sup 23} 14 MeV n/m{sup 2} at room temperature. Post-irradiation measurements were carried out to determine changes in high-frequency electrical conductivity, hardness, and density. It was found that neutron damage caused slight increases in conductivity and hardness. The major changes noted was in density, where a fluence of 4 {times} 10{sup 22} n/m{sup 2} caused swelling of 1.55 vol % while a dose of 1 {times} 10{sup 23} n/m{sup 2} resulted in a lower swelling value (0.82 vol %). This unusual behavior is explained by a model involving expansion of the mica phase of Macor and contraction of the glassy phase. Implications of the present results for engineering performance of Macor at these and higher fluences are discussed. 11 refs., 5 figs

Transportation of a 451 ton generator stator and a 234 ton generator rotor from Hartsville, TN, to Los Alamos, NM

A 1430 MVA steam turbine generator was acquired from a cancelled nuclear power plant in Tennessee to be used as the pulsed power and energy storage unit for the Confinement Physics Research Facility being built at Los Alamos, NM. The transportation from Hartsville, near Nashville, TN, to Los Alamos, NM, of the two largest single pieces of the generator, a 451 t stator and a 234 t rotor presented a special challenge. Details of the move, by barge from Hartsville to Catoosa, near Tulsa, OK, by rail from Catoosa to Lamy, near Santa Fe, NM, and by road from Lamy to Los Alamos are described. The greatest difficulty of the successful move was the crossing of the Rio Grande river on an existing reinforced concrete bridge. The two-lane wide road transporters for the stator and rotor were fitted with outriggers to provide a four-lane wide vehicle, thus spreading the load over the entire bridge width and meeting acceptable load distribution and bridge safety factors. 2 refs., 6 figs

SGW-35753-FP Revision 0 Treatability Test for Removing Technetium-99 from 200-ZP-1 Groundwater, Hanford Site FLUOR" Approved for Public Release; Further Dissemination UnlL'TIited Treatability Test for Removing Technetium-99 from 200-ZP-1 Groundwater, Hanf

ABSTRACT The 200-ZP-I Groundwater Operable Unit (OU) is one of two groundwater OUs located within the 200 West groundwater aggregate area of the Hanford Site. The primary risk-driving contaminants within the 200-ZP-I OU include carbon tetrachloride and technetium-99 (Tc-99). A pump-and-treat system for this OU was initially installed in 1995 to control the 0.002 kg 1m 3 (2000 IlgIL) contour of the carbon tetrachloride plume. Carbon tetrachloride is removed from groundwater with the assistance of an air-stripping tower. Ten extraction wells and three injection wells operate at a combined rate of approximately 0.017m 3/s (17.03 Lis). In 2005, groundwater from two of the extraction wells (299-WI5-765 and 299-WI5-44) began to show concentrations greater than twice the maximum contaminant level (MCL) ofTc-99 (33,309 beq/nr' or 900 pCi/L). The Tc-99 groundwater concentrations from all ten of the extraction wells when mixed were more than one-half of the MCL and were slowly increasing. If concentrations continued to rise and the water remained untreated for Tc-99, there was concern that the water re-injected into the aquifer could exceed the MCL standard. Multiple treatment technologies were reviewed for selectively removing Tc-99 from the groundwater. Of the treatment technologies, only ion exchange was determined to be highly selective, commercially available, and relatively low in cost. Through research funded by the U.S. Department of Energy, the ion-exchange resin Purolite® A-530E 1 was found to successfully removeTc-99 from groundwater, even in the presence of competing anions. For this and other reasons, Purolite® A-530E ion exchange resin was selected for treatability testing. The treatability test required installing resin columns on the discharge lines from extraction wells 299-W15-765 and 299-WI 5-44. Preliminary test results have concluded that the Purolite" A-530E' resin is effective at removing Tc-99 from groundwater to below detection limits even in the presence of competing anions (e.g., nitrate and sulfate) at concentrations five to six magnitudes higher than Tc-99.

Untersuchung der Auswirkungen erhoehter atmosphaerischer CO_2-Konzentrationen auf Weizenbestaende des Free-Air Carbondioxid Enrichment (FACE)-Experimentes Maricopa (USA) Abschlussbericht

A version of the demeter model was developed which describes both the quantitative and qualitative effects of elevated atmospheric CO_2 on a wheat crop under conditions of limited water and/or nitrogen supply. In the model's photosynthesis and energy balance modules, first versions of components were developed which it should be possible to apply in further ecosystem models (starting with the cereals models of the demeter family). Experimental data from the Maricopa FACE wheat experiments 1992-1996, in which scientists from PIK were involved, were used for the development and testing of the model. Model solutions obtained were applied for the first time of central European climatic and site conditions as part of a regional yield study for the Federal State of Brandenburg.
