1991 Environmental Monitoring Report Sandia National Laboratories, Albuquerque, New Mexico
This 1991 report contains monitoring data from routine radiological and nonradiological environmental surveillance activities. Summaries of significant environmental compliance programs in progress such as National Environmental Policy Act (NEPA) documentation, environmental permits, environmental restoration (ER), and various waste management programs for Sandia National Laboratories in Albuquerque (SNL, Albuquerque) are included. The maximum offsite dose impact was calculated to be 1.3 {times} 10{sup {minus}3} mrem. The total population within a 50-mile radius of SNL, Albuquerque, received a collective dose of 0.53 person-rem during 1991 from SNL, Albuquerque, operations. As in the previous year, the 1991 operations at SNL, Albuquerque, had no discernible impact on the general public or on the environment.

Absorption of undulator radiation in media
Detailed thermal stress analyses of beamline and optical components subject to high heat loads require an Accurate determination of the absorbed power profile for accurate prediction of the temperature profile and structural parameters. This is particularly important for high power beams from wigglers and undulators at the third generation synchrotron sources because components must, in general, be designed and maintained with strict mechanical tolerances. The spatial distribution of the power density of an undulator is a rapidly varying function of the energy of the photons suggesting that approximative methods based on a smooth spectral variation may not be valid. In this paper, a fast code for calculating undulator spectra is developed and compared with a wiggler code for approximation of the same spectra. Results from numerical simulations, including the emittance of the stored particle beam, are presented for the absorbed power density in a beryllium window. We find markedly different results for the two models for far off-axis radiation indicating the inadequacy of the wiggler model applied to an undulator spectrum in this case. The wiggler model overestimates the total absorbed power by as much as 82% for the beryllium window.

Active Sites Environmental Monitoring Program: FY 1991 report
This report summarizes the activities of the Active Sites Environmental Monitoring Program (ASEMP) from April 1991 through September 1991. The ASEMP was established in 1989 by Solid Waste Operations (SWO) and the Environmental Sciences Division, both of Oak Ridge National Laboratory, to provide early detection and performance monitoring at active low-level (radioactive) waste (LLW) disposal sites in Solid Waste Storage Area (SWSA) 6 and transuranic (TRU) waste storage sites in SWSA 5 as required by chapters II and III of US Department of Energy Order 5820.2A. A new set of action levels was developed on the basis of a statistical analysis of background contamination. These new action levels have been used to evaluate results in this report. Results of ASEMP monitoring continue to demonstrate that no LLW (except [sup 3]H) is being leached from the storage vaults on the tumulus pads. Loading of vaults on Tumulus II, which began in early FY 1991, was >90% complete at the end of September 1991. Results of sampling of groundwater and surface waters is presented.

Adapting to sea-level rise in the US Southeast: The influence of built infrastructure and biophysical factors on the inundation of coastal areas
The earth' s global mean surface air temperature has increased by 0.5[degrees]C over the past 100 years. This warming trend has occurred concurrently with increases in the concentration and number of greenhouse gases in the atmosphere. These gases may cause this trend to accelerate in the future and result in a net increase in the earth's global mean surface air temperature of 1.5 to 4.5[degrees]C by the year 2100. An increase of this magnitude could cause sea surface temperatures to increase would cause sea levels to rise -from thermal expansion of the sea, and the addition of melt waters from alpine glaciers and continental ice sheets. To allow for the cost-effective analysis of the impacts that sea-level rise may have on the US Southeast, a method is needed that will allow sites that are potentially at risk to be identified for study. Previously, no objective method was available to identify such sites. This project addresses this problem by using a geographic data base with information on both physical and climatological factors to identify coastal areas of the US Southeast that are at risk to inundation or accelerated erosion due to sea-level rise. The following six areas were selected for further …

Advanced alternate planar geometry solid oxide fuel cells
The potential of high temperature Solid Oxide Fuel Cells as high performance, high efficiency energy conversion device is well known. Investigation of several cell designs have been undertaken by various researchers to derive the maximum performance benefit from the device while maintaining a lower cost of production to meet the commercialization cost target. The present investigation focused on the planar SOFC design which allows for the use of mature low cost production processes to be employed. A novel design concept was investigated which allows for improvements in performance through increased interface stability, and lowering of cost through enhanced structural integrity and the use of low cost metal interconnects. The new cell design consisted of a co-sintered porous/dense/porous zirconia layer with the electrode material infiltrated into the porous layers. The two year program conducted by a team involving Ceramatec and the Institute of Gas Technology, culminated in a multi-cell stack test that exhibited high performance. Considerable progress was achieved in the selection of cell components, and establishing and optimizing the cell and stack fabrication parameters. It was shown that the stack components exhibited high conductivities and low creep at the operating temperature. The inter-cell resistive losses were shown to be small …

Advanced insulations for refrigerator/freezers: The potential for new shell designs incorporating polymer barrier construction
The impending phase-out of chlorofluorocarbons (CFCs) used to expand foam insulation, combined with requirements for increased energy efficiency, make the use of non-CFC-based high performance insulation technologies increasingly attractive. The majority of current efforts are directed at using advanced insulations in the form of thin, flat low-conductivity gas-filled or evacuated orthogonal panels, which we refer to as Advanced Insulation Panels (AIPs). AIPs can be used in composite with blown polymer foams to improve insulation performance in refrigerator/freezers (R/Fs) of conventional design and manufacture. This AIP/foam composite approach is appealing because it appears to be a feasible, near-term method for incorporating advanced insulations into R/Fs without substantial redesign or retooling. However, the requirements for adequate flow of foam during the foam-in-place operation impose limitations on the allowable thickness and coverage area of AIPs. This report examines design alternatives which may offer a greater increase in overall thermal resistance than is possible with the use of AIP/foam composites in current R/F design. These design alternatives generally involve a basic redesign of the R/F taking into account the unique requirements of advanced insulations and the importance of minimizing thermal bridging with high thermal resistance insulations. The focus here is on R/F doors because …

Advanced lightweight ceramic candle filter module
To determine the economic effect of light weight ceramics, several sizes of filters were cost estimated for operation at 217.5 psi (15 bar) based on the use of all light weight ceramics (Fibro/Fibro) vs. the use of cooled alloy (RA300) tubesheets and silicon carbide candles (Alloy/SiC). A jet pulse delivery system was included in both estimates. The Fibro/Fibro system was estimated with the plenum design while the Alloy/SiC system was based on header/nozzle design. Battery limits were the filters and jet pulse delivery systems, Ex-works, with no main valves or dust removal systems. It was found that the cost of Fibro/Fibro components were consistently lower than the cost of the Alloy/SiC components; this comparison is illustrated in Figure 8.

Advanced Methods for the Computation of Particle Beam Transport and the Computation of Electromagnetic Fields and Beam-Cavity Interactions. Final Report
The University of Maryland Dynamical Systems and Accelerator Theory Group carries out research in two broad areas: the computation of charged particle beam transport using Lie algebraic methods and advanced methods for the computation of electromagnetic fields and beam-cavity interactions. Important improvements in the state of the art are believed to be possible in both of these areas. In addition, applications of these methods are made to problems of current interest in accelerator physics including the theoretical performance of present and proposed high energy machines. The Lie algebraic method of computing and analyzing beam transport handles both linear and nonlinear beam elements. Tests show this method to be superior to the earlier matrix or numerical integration methods. It has wide application to many areas including accelerator physics, intense particle beams, ion microprobes, high resolution electron microscopy, and light optics. With regard to the area of electromagnetic fields and beam cavity interactions, work is carried out on the theory of beam breakup in single pulses. Work is also done on the analysis of the high frequency behavior of longitudinal and transverse coupling impedances, including the examination of methods which may be used to measure these impedances. Finally, work is performed on …

Analysis of Iodine-129 in aqueous samples by inductively coupled plasma-mass spectrometry
An inductively coupled plasma - mass spectrometry (ICP-MS) method was developed to determine the {sup 129}I content in aqueous environmental samples. Due to interference from xenon, direct measurement of {sup 129}I could not be made on the ICP-MS. An ion-exchange technique is used to concentrate the Iodine from one liter samples to 30 mL. The 30 mL eluant from the anion-exchange column is then introduced to the ICP-MS. The detection limit of the procedure is {le}O.5 pCi/L. Several samples from the Savannah River near the Savannah River Site (SRS) have been analyzed for {sup 129}I by this procedure. Concentrations of {sup 129}I in the Savannah River ranged from 0.05{plus_minus}0.12 to 0.21{plus_minus}0.49 pCi/L (95% CL). Below a seepage basin, in Four Mile Creek on the Savannah River Site, {sup 129}I concentrations were as high as 2.31{plus_minus}1.22 pCi/L. Before exiting the SRS the {sup 129}I concentration had decreased to 0.30{plus_minus}0.16 pCi/L by dilution in Four Mile Creek.

Analysis of soil and water for TATB content
A reverse-phase liquid chromatography (HPLC) method was developed for the analysis of TATB in soil samples. The soil samples were extracted with dimethylformamide (DMF). The extract was analyzed to determine the TATB content in the soil. The detection limit using this procedure was 2 parts/million (ppm) for TATB in the soil. An organic free sample of water was saturated with TATB. The water was filtered through a 0.2-{mu} filter, then injected into both a reverse-phase and normal-phase liquid chromatograph system. No peaks were detected. Therefore, the solubility of TATB in water is less than the detection limits of the chromatograph methods.

An analysis of the CDF monojet data
An analysis is presented of events with a single jet and significant missing transverse energy selected from 4.7 pb[sup [minus]1] of p[bar p] data at [radical]s = 1800 GeV. The goal is to identify events of the type p[bar p] [yields] Z[sup 0] + jet; Z[sup 0] [yields] [nu][bar [nu]]. Event selection backgrounds are discussed. The number of observed monojet events is compared to the number of observed Z[sup 0] [yields] e[sup +]e[sup [minus]] events in which the Z[sup 0] is accompanied by a jet. We measure the number of light neutrino species to be N[sub v] = 2.2 [plus minus] 1.5 and we place an upper limit on the cross section for new physics of 8.3 pb (95% C.L.)
