Studies of nuclear-waste migration in geologic media. Annual report, November 1976--October 1977

Description: The confinement of nuclear wastes in geologic formations is being considered as a method of permanently disposing of the waste. Laboratory experiments (column infiltration, static absorption, and batch partitioning experiments) were performed with nuclides of Cs, Pu, Np, and Am to examine the migratory characteristics of long-lived radionuclides that could be mobilized by groundwaters infiltrating a nuclear waste repository and the surrounding geologic body. In column infiltration experiments, … more

LIMB Demonstration Project Extension

Description: The basic goal of the Limestone Injection Multistage Burner (LIMB) demonstration is to extend LIMB technology development to a full- scale application on a representative wall-fired utility boiler. The successful retrofit of LIMB to an existing boiler is expected to demonstrate that (a) reductions of 50 percent or greater in SO{sub x} and NO{sub x} emissions can be achieved at a fraction of the cost of add-on FGD systems, (b) boiler reliability, operability, and steam production can be maintain… more

Water release from heated concretes

Description: Water release from three concretes as a function of temperature has been determined experimentally. Limestone concrete releases more water at a moderate temperature than do magnetite or basalt concretes. The amount of water in the concretes is 6.2%, 6.3%, and 5% by weight for limestone, basalt and magnitite concretes, respectively. All of the concretes show three distinct weight losses as a function of temperature. By 450K, 52 to 75 percent of the water is lost - all of the water is lost by 750… more

Microstructural interactions of geologic media with waste radionuclides

Description: A preliminary investigation of the microstructure of four geologic media was taken to examine the interaction of Cs, Sr, Gd and U with those media. Since K/sub D/ measurements often vary by more than an order of magnitude on rocks of the same strata separated by several feet, it was probable that minor rock components play an important role in radionuclide sorption. A qualitative analysis of the rock surfaces after equilibration with solutions of Cs/sup +/, Sr/sup + +/, Gd/sup + + +/ and UO/sub… more

Formation of calcium aluminates in the lime sinter process. [Extraction of alumina from fly ash]

Description: A study of the formation of several calcium aluminates from pure components in the lime sinter process was undertaken to determine the kinetics of formation and subsequent leaching using a dilute sodium carbonate solution. The composition CaO 61.98%, SiO/sub 2/ 26.67%, and Al/sub 2/O/sub 3/ 11.53% was used. Isothermal sintering runs of 0.2 to 10.0 h were carried out at 1200, 1250, 1300, and 1350/sup 0/C. When the sintering temperature was below the eutectic temperature (1335/sup 0/C), the terna… more

Compression wave studies in Oakhall limestone

Description: A series of 15 large amplitude (0-4.0 GPa) compression wave experiments have been performed on Oakhall limestone using impact techniques. Time-resolved particle velocity profiles were determined with window laser interferometry. Three experiments were performed at each impact velocity on samples of different thickness and stress-strain behavior was determined through Lagrangian analysis of the measured wave profiles. Two shock-induced phase transformations are observed within the range of the d… more

The use of wet limestone systems for combined removal of SO sub 2 and NO sub x from flue gas

Description: A new approach by utilizing yellow phosphorus in conventional wet limestone systems for high efficiency control of SO{sub 2} and NO{sub x} emissions from power plants has been developed. The addition of yellow phosphorus in the system induces the production of O{sub 3} which subsequently oxidizes NO to NO{sub 2}. The resulting NO{sub 2} dissolves readily and can be reduced to form ammonium ions by dissolved SO{sub 2} under appropriate conditions. Yellow phosphorus is oxidized to yield P{sub 2}O… more

Rivesville multicell fluidized bed boiler

Description: One objective of the experimental MFB at Rivesville, WV, was the evaluation of alternate feed systems for injecting coal and limestone into a fluidized bed. A continuous, uniform feed flow to the fluid bed is essential in order to maintain stable operations. The feed system originally installed on the MFB was a gravity feed system with an air assist to help overcome the back pressure created by the fluid bed. The system contained belt, vibrating, and rotary feeders which have been proven adequa… more

In situ vitrification of Oak Ridge National Laboratory soil and limestone

Description: Process feasibility studies were successfully performed on two different developmental scales to determine the technical application of in situ vitrification (ISV) to Oak Ridge National Laboratory (ORNL) intermediate-level waste. In the laboratory, testing was performed on crucibles containing quantities of 50% ORNL soil and 50% ORNL limestone. In the engineering-scale testing, a 1/12-scaled simulation of ORNL Trench 7 was constructed and vitrified, resulting in waste product soil and limestone… more

Stable Isotope Variations in Banded Iron Formations

Description: In spite of the significant amount of work already reported in the scientific literature, many aspects of the origin of Banded Iron Formations (BIF) remain enigmatic. The authors demonstrate that mineralogic microbanding in BIF is accompanied by autocorrelated isotopic microbanding of organic carbon and carbonate carbon and oxygen. They propose that these isotopic patterns formed as a result of episodic mixing of waters in the depositional environment of BIF.

Use of ``rock-typing`` to characterize carbonate reservoir heterogeneity. Final report

Description: The objective of the project was to apply techniques of ``rock-typing`` and quantitative formation evaluation to borehole measurements in order to identify reservoir and non-reservoir rock-types and their properties within the ``C`` zone of the Ordovician Red River carbonates in the northeast Montana and northwest North Dakota areas of the Williston Basin. Rock-typing discriminates rock units according to their pore-size distribution. Formation evaluation estimates porosities and pore fluid sat… more

Preparing to Submit a License Application for Yucca Mountain

Description: In 1982, the U.S. Congress passed the Nuclear Waste Policy Act, a Federal law that established U.S. policy for the permanent disposal of spent nuclear fuel and high-level radioactive waste. Congress amended the Act in 1987, directing the Department of Energy to study only Yucca Mountain, Nevada as the site for a permanent geologic repository. As the law mandated, the Department evaluated Yucca Mountain to determine its suitability as the site for a permanent geologic repository. Decades of scie… more

Groundwater chemistry at the Nevada Test Site: Data and preliminary interpretations

Description: The interpretation of chemical analyses of groundwater collected at and near the Nevada Test Site (NTS) has been vital in developing conceptual models of groundwater flow in the area. These conceptual models are tested using recent chemical data generated by the Desert Research Institute, as well as historic analyses from the US Geological Survey. A total of 81 wells are represented by analyses from 1957 to 1990, with generally excellent agreement between repeat samples from the same location. … more
