This final report includes details on the research accomplished by the grant entitled 'Exploitation of Parallelism in Climate Models' to the University of Maryland. The purpose of the grant was to shed light on (a) how to reconfigure the atmospheric prediction equations such that the time iteration process could be compressed by use of MPP architecture; (b) how to develop local subgrid scale models which can provide time and space dependent parameterization for a state-of-the-art climate model to minimize the scale resolution necessary for a climate model, and to utilize MPP capability to simultaneously integrate those subgrid models and their statistics; and (c) how to capitalize on the MPP architecture to study the inherent ensemble nature of the climate problem. In the process of addressing these issues, we created parallel algorithms with spectral accuracy; we developed a process for concurrent climate simulations; we established suitable model reconstructions to speed up computation; we identified and tested optimum realization statistics; we undertook a number of parameterization studies to better understand model physics; and we studied the impact of subgrid scale motions and their parameterization in atmospheric models.

A major milestone was reached in Fiscal Year (FY) 2000--the completion of the Chicago Pile-5 (CP-5) D and D Project. CP-5, the first reactor built on the Argonne National Laboratory-East (ANL-E) site, was a 5-megawatt, heavy water-moderated, enriched uranium-fueled reactor. It was the principal reactor on the Argonne site used to produce neutrons for scientific research from 1954 to 1979. The reactor was shut down and defueled in 1979, and placed in a lay-up condition. In 1990, funding was provided to begin the decontamination and decommissioning (D and D) of this facility, and work began in June 1991. D and D tasks were performed by both ANL-E personnel and subcontractor personnel from Duke Engineering and Services, Marlborough MA, under the management of ANL-E D and D Program personnel. In July 2000, the final project report was presented to the Department of Energy, and the facility was formally decommissioned and transferred to the landlord. Total project duration was 97 months, and total project cost was $29.5M. Also, in FY 2000, work began on the 60 Cyclotron D and D Project. An accelerator used for basic research, this facility produced beams of deuterons, helium ions, singly charged hydrogen molecules, and neutrons of …

The purpose of this Analysis/Model Report (AMR) is to document the Near-Field Environment (NFE) and Unsaturated Zone (UZ) models used to evaluate the potential effects of coupled thermal-hydrologic-chemical (THC) processes on unsaturated zone flow and transport. This is in accordance with the ''Technical Work Plan (TWP) for Unsaturated Zone Flow and Transport Process Model Report'', Addendum D, Attachment D-4 (Civilian Radioactive Waste Management System (CRWMS) Management and Operating Contractor (M and O) 2000 [153447]) and ''Technical Work Plan for Nearfield Environment Thermal Analyses and Testing'' (CRWMS M and O 2000 [153309]). These models include the Drift Scale Test (DST) THC Model and several THC seepage models. These models provide the framework to evaluate THC coupled processes at the drift scale, predict flow and transport behavior for specified thermal loading conditions, and predict the chemistry of waters and gases entering potential waste-emplacement drifts. The intended use of this AMR is to provide input for the following: (1) Performance Assessment (PA); (2) Abstraction of Drift-Scale Coupled Processes AMR (ANL-NBS-HS-000029); (3) UZ Flow and Transport Process Model Report (PMR); and (4) Near-Field Environment (NFE) PMR. The work scope for this activity is presented in the TWPs cited above, and summarized as follows: continue …

Nicolet Biomedical Inc. (NBI) is collaborating with Oak Ridge National Laboratory (ORNL) under a Cooperative Research and Development Agreement (CRADA) to convert ORNL.s patented technology for forewarning of epileptic seizures to a clinical prototype. This technical report describes the highlights of the first year.s effort. The software requirements for the clinical device were specified from which the hardware specifications were obtained. ORNL's research-class FORTRAN was converted to run under a graphical user interface (GUI) that was custom-built for this application by NBI. The resulting software package was cloned to desktop computers that are being tested in five different clinical sites. Two hundred electroencephalogram (EEG) datasets from those clinical sites were provided to ORNL for detailed analysis and improvement of the forewarning methodology. Effort under this CRADA is continuing into the second year as planned.

We have investigated the use of a synchrotron as a source for infrared photoacoustic spectroscopy. A synchrotron has an intrinsically high radiance, which is beneficial when photoacoustic spectroscopy is applied to small samples, especially at long wavelengths.

The immobilization of plutonium-containing wastes into stable solid compositions is one of the problems to be solved in the disposal of radioactive wastes. Research efforts on the selection, preparation with the use of the cold crucible induction melter (CCIM) technology, and investigation of materials that are most suitable for immobilizing plutonium-containing wastes of different origin have been carried out at the All-Russian Scientific Research Institute of Inorganic Materials (VNIINM) and the Institute of the Geology of Ore Deposits, Petrography, Mineralogy, and Geochemistry (IGEM), Russian Academy of Sciences within the framework of agreements with Lawrence Livermore National Laboratory (LLNL, USA) regarding material and technical support. This paper presents the data on the synthesis of cerium-, uranium-, and plutonium-containing materials based on borobasalt, pyroxene, and andradite compositions in the muffle furnace and by the CCIM method. Compositions containing up to 15-18 wt% cerium oxide, 8-11 wt% uranium oxide, and 4.6-5.7 wt% plutonium oxide were obtained in laboratory facilities installed in glove boxes. Comparison studies of the materials synthesized in the muffle furnace and CCIM demonstrate the advantages of using the CCIM method. The distribution of components in the materials.

This note will outline the sensitivity to emittance blowup of antiproton transfers due to quadrupole focussing and quadrupole steering errors in the 8 GeV AP3-P1 transfer line. It will be shown that these tolerances are much larger than the dipole steering tolerances discussed in PBAR Note 649. This note will use the lattice discussed in PBAR Note 648.

The Weather Research and Forecast (WRF) project is a multi-institutional effort to develop an advanced mesoscale forecast and data assimilation system that is accurate, efficient, and scalable across a range of scales and over a host of computer platforms. The first release, WRF 1.0, was November 30, 2000, with operational deployment targeted for the 2004-05 time frame. This paper provides an overview of the project and current status of the WRF development effort in the areas of numerics and physics, software and data architecture, and single-source parallelism and performance portability.

Calibration of seismic nuclear test monitoring stations relies on a diverse reference-event database. The reference-event covariance structure must be characterized and the covariance propagated to subsequent processes and calibration products. In seismic location one of the first steps in the calibration process is declustering, in which closely spaced epicenters are combined to reduce redundant data and random observational errors. We formulate a new declustering procedure that accounts for correlated and uncorrelated components of reference-event error, producing a declustered data set that tracks raw reference-event uncertainties. Declustering behavior is demonstrated using example data sets.

The principal task of our studies is to provide a rational interpretation of the thermodynamic and fluid dynamic events taking place in a closed vessel upon detonation of an explosive charge and subsequent turbulent combustion of its products, acting as fuel for an exothermic reaction with air. Under such circumstances, the latter has been compressed by a reverberating shock front of the blast wave generated by the explosion. The paper presents the chemical and thermodynamic background and its numerical results, deduced for this purpose from mass spectroscopic data and pressure records, acquired upon explosion of a 0.8 kg charge of TNT in a 17 m{sup 3} chamber filled with air--a diagnostic analysis identified by the title. The evolution of the flow field and its structure are presented in a companion paper.

This change enabled the retention of a De Minimus level of emissions for the manufacturing plant, …

A facility for measurement of rare Kr-81 and Kr-85 isotope concentration in hydrogeologic samples, and isotopic composition of minute quantities of krypton and xenon from extraterrestrial samples, was established, requiring refinement of an emerging mass spectrometric-based analytical technique and securing of laboratory space and equipment. The analytical process consists of (1) collecting a groundwater sample, (2) degassing the water, (3) separating Kr from the recovered gases, (4&5) two isotopic enrichments to reduce interfering isotopes by E9, and (6) detecting the rare krypton isotope in a unique time-of-flight mass spectrometer detecting as few as 100 Kr atoms. All equipment is installed and operating, with only some additional adjustment and testing of the last step (6, above) remaining to be completed. Collaborations have been established with a number of researchers and organizations world wide, and both groundwater and extraterrestrial samples have been collected. Completion of analyses awaits full operation of step 6.
