Cooperative Research and Development Agreements (open access)

Cooperative Research and Development Agreements

A Cooperative Research and Development Agreement (CRADA) is a mechanism established by P.L. 99-602, the Federal Technology Transfer Act, to allow the transfer of technology, knowledge, and expertise from government laboratories to the private sector for further development and commercialization. The government provides support in the way of overhead for research and development performed in the federal laboratory and is prohibited from providing funding directly to the partner in the collaborative effort. Currently, more than 5,000 CRADAs have been signed. As the 105th Congress determines its approach to science and technology policies, the role of CRADAs continues to be debated within the context of federal support for R&D

The Au Pair Program (open access)

The Au Pair Program

Legislation passed late in the 103rd Congress granted the U.S. Information Agency (USIA) authority to design and implement more rigorous rules regulating the au pair program. In 1997, the au pair program received considerable media attention as a result of the Louise Woodward court case regarding possible involvement of an au pair in the death of a child in Massachusetts. The U.S. Information Agency amended existing federal regulations for the au pair program in September 1997 to underscore the cultural exchange aspect of the program and strengthen au pair recruiting and training.

The "Son of Sam" Case: Legislative Implications (open access)

The "Son of Sam" Case: Legislative Implications

In Simon & Schuster, Inc. v. Members of the new York State Crime Victims Board, the U.S. Supreme Court held that New York State's "Son of Sam" law was inconsistent with the First Amendment's guarantee of freedom of speech and press. This report examines the Supreme Court decision and then considers whether its rationale renders the federal law unconstitutional. Concluding that it likely does, the report considers whether it would be possible to enact a constitutional Son-of-Sam statute. Finally, the report takes note of some state Son-of-Sam statutes that have been enacted since the Supreme Court decision.

This Closure Report provides the documentation for closure of the Roller Coaster Sewage Lagoons and North Disposal Trench Comective Action Unit (CAU) 404. CAU 404 consists of the Roller Coaster Sewage Lagoons (Corrective Action Site [CAS] TA-03-O01-TA-RC) and the North Disposal Trench (CAS TA-21-001-TA-RC). The site is located on the Tonopah Test Range, approximately 225 kilometers (km) (140 miles [mi]) northwest ofLas Vegas, Nevada. . The sewage lagoons received ~quid sanitary waste horn the Operation Roller Coaster Man Camp in 1963 and debris from subsequent range and construction cleanup activities. The debris and ordnance was subsequently removed and properly dispos~, however, pesticides were detected in soil samples born the bottom of the lagoons above the U,S. Environmental Protection Agency Region IX Prelimimuy Remediation Goals (EPA 1996). . The North Disposal Trench was excavated in 1963. Debris from the man camp and subsequent range and construction cleanup activities was placed in the trench. Investigation results indicated that no constituents of concern were detected in soil samples collected from the trench. Remedial alternative proposed in the Comctive Action Decision Document (CADD) fm the site was “Covering” (DOE, 1997a). The Nevada Division of”Enviromnental Protection (NDEP)-approved Correction Action Plan (CAP) proposed the “Covering” niethodology …

Evaluation of near field rock treatment during constructions (LADSfeature #22) (open access)

Evaluation of near field rock treatment during constructions (LADSfeature #22)

The purpose of this report is to evaluate the effect of near-field rock treatment by injection of reactive material (calcite) above the drift for the purpose of decreasing postclosure drift seepage. The method used for the calculation was a coupled reaction-transport numerical model for gas-water-rock interaction. This includes the mass conservation of heat, liquid and gas for thermohydrological calculations, of aqueous and gaseous species for advective and diffusive transport, and the kinetics of mineral-water reactions.

Coupled modeling of non-isothermal multiphase flow, solutetransport and reactive chemistry in porous and fractured media: 1. ModelDevelopment and Validation (open access)

Coupled modeling of non-isothermal multiphase flow, solutetransport and reactive chemistry in porous and fractured media: 1. ModelDevelopment and Validation

Coupled modeling of subsurface multiphase fluid and heat flow, solute transport and chemical reactions can be used for the assessment of acid mine drainage remediation, mineral deposition, waste disposal sites, hydrothermal convection, contaminant transport, and groundwater quality. Here they present a numerical simulation model, TOUGHREACT, which considers non-isothermal multi-component chemical transport in both liquid and gas phases. A wide range of subsurface thermo-physical-chemical processes is considered. The model can be applied to one-, two- or three-dimensional porous and fractured media with physical and chemical heterogeneity. The model can accommodate any number of chemical species present in liquid, gas and solid phases. A variety of equilibrium chemical reactions is considered, such as aqueous complexation, gas dissolution/exsolution, cation exchange, and surface complexation. Mineral dissolution/precipitation can proceed either subject to local equilibrium or kinetic conditions. The coupled model employs a sequential iteration approach with reasonable computing efficiency. The development of the governing equations and numerical approach is presented along with the discussion of the model implementation and capabilities. The model is verified for a wide range of subsurface physical and chemical processes. The model is well suited for flow and reactive transport in variably saturated porous and fractured media.

Numerical analysis of thermal-hydrological conditions in thesingle heater test at Yucca Mountain (open access)

Numerical analysis of thermal-hydrological conditions in thesingle heater test at Yucca Mountain

The Single Heater Test (SHT) is one of two in-situ thermal tests included in the site characterization program for the potential underground nuclear waste repository at Yucca Mountain. The heating phase of the SHT started in August 1996, and was completed in May 1997 after 9 months of heating. The coupled processes in the unsaturated fractured rock mass around the heater were monitored by numerous sensors for thermal, hydrological, mechanical and chemical data. In addition to passive monitoring, active testing of the rock mass moisture content was performed using geophysical methods and air injection testing. The extensive data set available from this test gives a unique opportunity to improve the understanding of the thermal-hydrological situation in the natural setting of the repository rocks. The present paper focuses on the 3-D numerical simulation of the thermal-hydrological processes in the SHT using TOUGH2. In the comparative analysis, they are particularly interested in the accuracy of different fracture-matrix-interaction concepts such as the Effective Continuum (ECM), the Dual Continuum (DKM), and the Multiple Interacting Continua (MINC) method.

Structural Formation Studies of UV-Catalyzed Gels and Aerogels by Light Scattering (open access)

Structural Formation Studies of UV-Catalyzed Gels and Aerogels by Light Scattering

The skeletal structure of aerogel is determined before, during, and after the gel is formed. Supercritical drying of aerogel largely preserves the pore structure that is determined near the time of gelation. To better understand these gel formation mechanisms we carried out measurements of the time evolution of light scattering in a series of gels prepared without conventional acid or base catalysis. Instead, ultraviolet light was used to catalyze the formation of silica gels made from the hydrolysis of tetraethylorthosilicate and partly prehydrolyzed tetraethylorthosilicate in ethanol. Time evolution of light scattering provides information regarding the rate and geometrical nature of the assembly of the primary silica particles formed in the sol. UV-catalyzed gels show volumetric growth typical of acid-catalyzed gels, except when UV exposure is discontinued at the gel point, where gels then show linear chain formation typical of base-catalyzed gels. Long term UV exposure leads to coarsening of the pore network, a decrease in the clarity of the aerogel, and an increase in the surface area of the aerogel. Additionally, UV exposure up to the gel point leads to increased crystallinity in the final aerogel.
