The Law of Church and State: Public Aid to Sectarian Schools (open access)

The Law of Church and State: Public Aid to Sectarian Schools

One of the most difficult issues of constitutional law concerns the extent to which the establishment of religion clause of the First Amendment imposes constraints on the provision of public aid to private sectarian schools. This report gives a brief overview of the evolution of the Court’s interpretation of the establishment clause in this area and itemizes the categories of aid that have been addressed by the Court and held to be constitutionally permissible or impermissible, both at the elementary and secondary school level and at the college level.

The Design of a Novel Survey for Small Objects in the Solar System (open access)

The Design of a Novel Survey for Small Objects in the Solar System

We evaluated several concepts for a new survey for small objects in the Solar System. We designed a highly novel survey for comets in the outer region of the Solar System, which exploits the occultations of relatively bright stars to infer the presence of otherwise extremely faint objects. The populations and distributions of these objects are not known; the uncertainties span orders of magnitude! These objects are important scientifically as probes of the primordial solar system, and programmatically now that major investments may be made in the possible mitigation of the hazard of asteroid or comet collisions with the Earth.

Advanced Industrial Materials (AIM) Program Compilation of Project Summaries and Significant Accomplishments FY 1999

For the past 10 years the Advanced Industrial Materials (AIM) has supported development of new and improved materials to enable U.S. industry to improve energy efficiency, increase productivity, and reduce waste. It has been a National Laboratory based program, with work currently under way at Oak Ridge National Laboratory, Los Alamos National Laboratory, and Sandia National Laboratories, in collaboration with industrial and university partners. With the advent of the Industries of the Future (IOF) strategy within the Office of Industrial Technologies (OIT) and the scheduled completion of the Continuous Fiber Ceramic Composites (CFCC) Program in FY 2002, an integrated materials program is being developed in OIT. So this represents the last summary of AIM research and development. The new program, Industrial Materials for the Future (IMF), will be competitive in operation, with solicitations for proposals for development of materials in accordance with the IOF Technology Roadmaps, followed by merit review and funding of the best proposals. Industry will take the lead in ''industry-specific'' research and development, in cooperation with National Laboratories, as needed. National Laboratories and universities will take the lead in maintaining a base technology program, for the purpose of maintaining a continuing flow of new materials technologies. The …

Protocol for development of authorized release limits for concrete at U.S. Department of Energy sites (open access)

Protocol for development of authorized release limits for concrete at U.S. Department of Energy sites

The purpose of this protocol is to assist US Department of Energy (DOE) sites in releasing concrete for reuse. Current regulations allow the sites to release surface-contaminated materials if their radioactivity falls below certain levels and to possibly release materials with volumetric contamination or higher levels of surface contamination on a case-by-case basis. In all cases, an ALARA (as low as reasonably achievable) analysis that evaluates the risks of releasing volumetrically contaminated concrete or concrete with higher levels of surface contamination is required as a basis for proposing and setting new release limits that allow for reuse of the concrete material. To evaluate the dose impacts of reusing radioactively contaminated material, the measured radiation levels (pCi/g or disintegrations per minute [dpm]/100 cm{sup 2}) must be converted to the estimated dose (mrem/yr) that would be received by affected individuals. The dose depends on the amounts and types of isotopes present and the time, distance, and method of exposure (e.g., inhalation or external exposure). For each disposition alternative, the protocol provides a systematic method to evaluate the impact of the dose on the affected individuals. The cost impacts of reusing concrete also need to be evaluated. They too depend on the disposition …

Enabling Computational Technologies for Terascale Scientific Simulations (open access)

Enabling Computational Technologies for Terascale Scientific Simulations

We develop scalable algorithms and object-oriented code frameworks for terascale scientific simulations on massively parallel processors (MPPs). Our research in multigrid-based linear solvers and adaptive mesh refinement enables Laboratory programs to use MPPs to explore important physical phenomena. For example, our research aids stockpile stewardship by making practical detailed 3D simulations of radiation transport. The need to solve large linear systems arises in many applications, including radiation transport, structural dynamics, combustion, and flow in porous media. These systems result from discretizations of partial differential equations on computational meshes. Our first research objective is to develop multigrid preconditioned iterative methods for such problems and to demonstrate their scalability on MPPs. Scalability describes how total computational work grows with problem size; it measures how effectively additional resources can help solve increasingly larger problems. Many factors contribute to scalability: computer architecture, parallel implementation, and choice of algorithm. Scalable algorithms have been shown to decrease simulation times by several orders of magnitude.

Chemical Conversion of TNT: Production of 2,4,6-Trinitrobenzoic Acid (open access)

Chemical Conversion of TNT: Production of 2,4,6-Trinitrobenzoic Acid

Oxidation of 2,4,6-trinitrotoluene (TNT) by aqueous nitric acid at high temperature and pressure gives 2,4,6-trinitrobenzoic acid (TNBA) and other valuable products, such as 1,3,5-trinitrobenzene (TNB). Optimization of the kinetics proved to be critical for the selective oxidation of the methyl group. High yield of a desired product can be obtained only under a narrow range of conditions. Thus, the best yield (70 to 75%) of TNBA was achieved at a 35 to 45% conversion of TNT (80% nitric acid, 194 C, 20 min), whereas the decarboxylation product (TNB) was the major component of the reaction mixture after a 50-min reaction. Subsequent separation of TNBA was achieved by selective extraction with aqueous bicarbonate. Practical technology development steps for a continuous mode of operation leading to the chief products are also discussed. This technology can use commercial raw trotyl and trotyl from discharged ammunition as the starting material. The latter could be of particular importance for the conversion program aimed at the utilization of ammunition supplies.

PFP Commercial Grade Food Pack Cans for Plutonium Handling and Storage Critical Characteristics (open access)

PFP Commercial Grade Food Pack Cans for Plutonium Handling and Storage Critical Characteristics

This screening addresses the critical characteristics for food industry type cans and containers used for handling and storage of special nuclear materials at the Plutonium Finishing Plant (PFP). HNF-5460, Revision 0 specified a minimum tin plate of 0.50 Ib./base box. Since the food pack cans currently used and that have been tested have a listed tin plate of 0.20 lbs. per base box, Revision 1 reduced the tin plate to {ge} 0.20 Ib./base box (i.e., No. 20 tinned commercial steel or heavier). This revision lists Critical Characteristics for two (2) large filtered containers, and associated shielding over-packs. These new containers are called ''Nuclear Material Containers'' (NMCs). They are supplied in various sizes, which can be nested, one inside another. The PFP will use NMCs with volumes up to 8-quarts as needed to over-pack largely bulged containers.

Yield strength anomaly and the environmental effect in FeAl. Final report for the period September 1, 1996 - August 31, 2000 (open access)

Yield strength anomaly and the environmental effect in FeAl. Final report for the period September 1, 1996 - August 31, 2000

The aim of the work here was to understand both the yield anomaly in FeAl, which was first noted by the P.I. and collaborators, and the effect of environment on the fracture of FeAl. The progress in these areas is outlined below. A model for the yield anomaly developed as part of this work served as the basis for a successful proposal to NSF to study the yield anomaly in other B2 compounds. The effects of vacancies and of boron on flow and fracture at room temperature were also addressed. Recrystallization and grain growth were studied In both FeAl and Ni{sub 3}Al. Strain-induced ferromagnetism was studied in FeAl and a model for the paramagnetic-to-ferromagnetic transition was developed based on antiphase boundary tubes. A successful proposal was also submitted to NSF on this topic. Finally, in addition to a number of papers and Presentations on our experimental work, several invited presentations and published reviews, including a major review in International Material Reviews, on the mechanical properties of either FeAl or B2 compounds were made.
