Ambient air pollution exposure and the incidence of related health effects among racial/ethnic minorities
Differences among racial and ethnic groups in morbidity and mortality rates for diseases, including diseases with environmental causes, have been extensively documented. However, documenting the linkages between environmental contaminants, individual exposures, and disease incidence has been hindered by difficulties in measuring exposure for the population in general and for minority populations in particular. After briefly discussing research findings on associations of common air pollutants with disease incidence, the authors summarize recent studies of radial/ethnic subgroup differences in incidence of these diseases in the US. They then present evidence of both historic and current patterns of disproportionate minority group exposure to air pollution as measured by residence in areas where ambient air quality standards are violated. The current indications of disproportionate potential exposures of minority and low-income populations to air pollutants represent the continuation of a historical trend. The evidence of linkage between disproportionate exposure to air pollution of racial/ethnic minorities and low-income groups and their higher rates of some air pollution-related diseases is largely circumstantial. Differences in disease incidence and mortality rates among racial/ethnic groups are discussed for respiratory diseases, cancers, and lead poisoning. Pollutants of concern include CO, Pb, SO{sub 2}, O{sub 3}, and particulates.

Analysis of fluid-structural instability in water
Recent flow testing of stainless steel hardware in a high pressure/high temperature water environment produced an apparent fluid-structural instability. The source of instability was investigated by studying textbook theory and by performing NASTRAN finite element analyses. The modal analyses identified the mode that was being excited, but the flutter instability analysis showed that the design is stable if minimal structural damping is present. Therefore, it was suspected that the test hardware was the root cause of the instability. Further testing confirmed this suspicion.

Analysis of Sr{Sub 5{Minus}X}Ba{Sub X}(Po{Sub 4}){Sub 3}F:Yb{Sup 3+} Crystals for Improved Laser Performance With Diode-Pumping
Crystals of Yb{sup 3+}:Sr{sub 1-x}Ba{sub x}(PO{sub 4}){sub 3}F (0 < x < 5) have been investigated as a means to obtain broader absorption bands than are currently available with Yb{sup 3+}:S-FAP [Yb{sup 3+}: Sr{sub 5}(PO{sub 4}){sub 3}F], thereby improving diode-pumping efficiency for high peak power applications. Large diode-arrays have a FWHM pump band of >5 nm while the FWHM of the 900 nm absorption band for Yb:S-FAP is 5.5 nm; therefore, a significant amount of pump power can be wasted due to the nonideal overlap. Spectroscopic analysis of Yb:Sr{sub 5-x}Ba{sub x}-FAP crystals indicates that adding barium to the lattice increases the pump band to 13-16 run which more than compensates for the diode-array pump source without a detrimental reduction in absorption cross section. However, the emission cross section decreases by approximately half with relatively no effect on the emission lifetime. The small signal gain has also been measured and compared to the parent material Yb:S-FAP and emission cross sections have been determined by the method of reciprocity, the Filchtbauer-Ladenburg method, and small signal gain. Overall, Yb{sup 3+}:Sr{sub 5-x}Ba{sub x}(PO{sub 4}){sub 3}F crystals appear to achieve the goal of nearly matching the favorable thermal and laser performance properties of Yb:S-FAP while …

Analytical chemistry of aluminum salt cake
Component phases of Al salt cake or products from processing salt cake, resist dissolution, a key first step in most analysis procedures. In this work (analysis support to a study of conversion of salt cake fines to value-added oxide products), analysis methods were adapted or devised for determining leachable salt, total halides (Cl and F), Al metal, and elemental composition. Leaching of salt cake fines was by ultrasonic agitation with deionized water. The leachate was analyzed for anions by ion chromatography and for cations by ICP-atomic emission spectroscopy. Only chloride could be measured in the anions, and charge balances between cations and chloride were near unity, indicating that all major dissolved species were chloride salts. For total halides, the chloride and fluorides components were first decomposed by KOH fusion, and the dissolved chloride and fluoride were measured by ion chromatography. Al metal in the fines was determined by a hydrogen evolution procedure adapted for submilligram quantities of metallic Al: the Al was reacted with HCl in a closed system containing a measured amount of high-purity He. After reaction, the H/He ratio was measured by mass spectroscopy. Recoveries of Al metal standards (about 30mg) averaged 93%. Comparison of the acid evolution …

Analyzing the rod drop accident in a BWR with high burnup fuel
The response of fuel in a boiling water reactor to the rod drop accident (RDA) was studied using the RAMONA-4B computer code. Calculations of this design-basis event has been done conservatively because there was margin to the fuel failure criterion of 170 cal/g. Because high burnup fuel may fail at much lower fuel enthalpies, the best-estimate of the enthalpy and the uncertainty is of interest. In part of this study, calculations assessed the sensitivity to reactor conditions such as control rod pattern, inlet subcooling, and fuel burnup. It was shown that fuel enthalpy at any location in the region surrounding the dropped rod depends on the rod worth, the distance from the dropped rod, and the burnup of the fuel. The study also calculated the sensitivity to parameters whose modeling introduces significant uncertainty which may increase with burnup. These parameters are the control rod worth, Doppler reactivity coefficient, delayed neutron precursor fraction, and fuel specific heat. The results of the sensitivity studies were used in a model to determine the random uncertainty in the fuel enthalpy. The standard deviation for the calculated fuel enthalpy was estimated to be 37%. Therefore, the limiting bundle fuel enthalpy might be 75% higher than …

Analyzing the rod drop accident in a BWR with high burnup fuel. Revised
The response of fuel in a boiling water reactor to the rod drop accident (RDA) was studied using the RAMONA-4B computer code. In this study, a fit of RAMONA-4B bundle powers was used to estimate the local power peaking. It was determined that the peaking factor could be 25% higher than the factor usually assumed for RDA analysis. Combining this error with the 2 sigma random error means that for this analysis the actual fuel rod enthalpy could be 100% larger than calculated by RAMONA-4B. This is much larger than the uncertainty in most parameters that are calculated with best-estimate methods for other design-basis events.

Anisotropic porous metals production by melt processing
The collapse of the Soviet Union has left many of its scientific institutes and technical universities without their traditional backbone of financial support. In an effort to stem the export of science to nations advocating nuclear proliferation, and to acquire potentially useful technology, several US government-sponsored programs have arise to mine the best of former USSR scientific advances. In the field of metallurgy, the earliest institutes to be investigated by Sandia National Laboratories are located in Ukraine. In particular, scientists at the State Metallurgical Academy have developed unique porous metals, resembling what could be described as gas-solid ``eutectic``. While porous metals are available in the US and other western countries, none have the remarkable structure and properties of these materials. Sandia began a collaborative program with the Ukrainian scientists to bring this technology to the US, verify the claims regarding these materials, and begin production of the so-called Gasars. This paper will describe the casting process technology and metallurgy associated with the production of Gasars, and will review the progress of the collaborative project.
