Los Alamos Transuranic Waste Size Reduction Facility (open access)

Los Alamos Transuranic Waste Size Reduction Facility

The Los Alamos Transuranic (TRU) Waste Size Reduction Facility (SRF) is a production oriented prototype. The facility is operated to remotely cut and repackage TRU contaminated metallic wastes (e.g., glove boxes, ducting and pipes) for eventual disposal at the Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico. The resulting flat sections are packaged into a tested Department of Transportation Type 7A metal container. To date, the facility has successfully processed stainless steel glove boxes (with and without lead shielding construction) and retention tanks. We have found that used glove boxes generate more cutting fumes than do unused glove boxes or metal plates - possibly due to deeply embedded chemical residues from years of service. Water used as a secondary fluid with the plasma arc cutting system significantly reduces visible fume generation during the cutting of used glove boxes and lead-lined glove boxes. 2 figs., 1 tab.

An analysis of loss of offsite power with a PWR at shutdown (open access)

An analysis of loss of offsite power with a PWR at shutdown

In many Probabilistic Risk Assessments (PRAs), loss of offsite power (LOOP) when a nuclear power plant is operating was found to be a significant contributor to core damage. The purpose of this study is to provide an analysis of a loss of offsite power event that occurs while a PWR is shut down. The importance of such an analysis was recognized as part of a study to evaluate the core damage frequency due to a loss of decay heat removal capability during an outage. 5 refs., 1 fig.

Analysis of pressure, enthalpy and CO/sub 2/ transients in well BR21, Ohaaki, New Zealand (open access)

Analysis of pressure, enthalpy and CO/sub 2/ transients in well BR21, Ohaaki, New Zealand

Numerical studies are undertaken, which incorporate both double porosity and noncondensible gas effects, to determine the characteristics of the reservoir near well BR21 of Ohaaki geothermal field, New Zealand. It is shown that the application of numerical techniques to analyze two-phase well data can provide valuable information that may not otherwise be obtained. Numerical techniques allow more of the true reservoir complexities to be included, further constraining the results. The model developed adequately matches observed pressure, enthalpy and flowing CO/sub 2/ mass fraction while providing estimates of important reservoir parameters.

Analysis of surface contaminants on beryllium and aluminum windows (open access)

Analysis of surface contaminants on beryllium and aluminum windows

An effort has been made to document the types of contamination which form on beryllium window surfaces due to interaction with a synchrotron radiation beam. Beryllium windows contaminated in a variety of ways (exposure to water and air) exhibited surface powders, gels, crystals and liquid droplets. These contaminants were analyzed by electron diffraction, electron energy loss spectroscopy, energy dispersive x-ray spectroscopy and wet chemical methods. Materials found on window surfaces include beryllium oxide, amorphous carbon, cuprous oxide, metallic copper and nitric acid. Aluminum window surface contaminants were also examined.

Application of a two fluid theoretical plasma transport model on current tokamak reactor designs. [TIBER II Engineering Test Reactor]

In this work, the new theoretical transport models to TIBER II design calculations are described and the results are compared with recent experimental data in large tokamaks (TFTR, JET). Tang's method is extended to a two-fluid model treating ions and electrons separately. This allows for different ion and electron temperatures, as in recent low-density experiments in TFTR, and in the TIBER II design itself. The discussion is divided into two parts: (1) Development of the theoretical transport model and (2) calibration against experiments and application to TIBER II.

Approaches to the assessment of injuries to soil arising from discharges of hazardous substances and oil: Type B, Technical information document

Methods for determining the nature and magnitude of injury to the following natural resources are described for: soil chemical characteristics (acidity or pH, cation exchange capacity, percent base saturation, salinity); soil physical characteristics (porosity, water holding capacity, aggregate stability); biological characteristics (microbial activities, invertebrate activities, vegetation); and contaminant transport potential (leaching, food chain). In addition, this document explains how injuries to the soil resource can be translated into a reduction in service provided by that soil and how to determine soil recovery potential. That portion of 43 CFR Part 11 that pertains to the soils portion of the geologic resource is explained.

Assessment of pulverized-coal-fired combustion performance: Final report for the period September 1980--September 1983

The purpose of this program was to evaluate an engineering analysis procedure which could be used to assess the impact on thermal performance of converting gas and oil fired equipment to coal. The program consisted of four major tasks: (1) Engineering Analysis. The objective was to evaluate currently available models which could be used to predict combustor performance and to define a procedure which could be used to assess the impact of a coal firing in a boiler or furnace; (2) Reactor Studies. The purpose was to evaluate, under controlled conditions, the radiative properties of fly ash clouds; (3) Pilot Scale Experiments. This involved a combustion trial with gas and coals which were burned at 0.7 /times/ 10/sup 6/ Btu/hr in a pilot-scale combustor. The purpose was to verify and supplement the results of the small-scale reactor studies on the radiant properties of coal flames at larger scale; (4) Reporting. Engineering analysis procedures were used to identify those fuels related properties which had a major impact on the thermal performance of furnaces. The major result of the study is that thermal performance of coal-fired furnaces is dominated by the formation of fly ash deposits on the heat transfer surfaces. The …

Assumptions, uncertainties, and limitations in the predictive capabilities of models for sensitization in 304 stainless steels (open access)

Assumptions, uncertainties, and limitations in the predictive capabilities of models for sensitization in 304 stainless steels

A review of literature on sensitization in 304 stainless steels has been made from what we believe would be the regulatory framework evaluating the claim that there is reasonable assurance that predicts the absence of sensitization for the times (300 to 1000 years) and temperatures (below about 200{sup 0}C) associated with a high-level waste (HLW) repository at Yucca Mountain. We conclude that such a claim would be indefensible. 17 refs.

Asymptotic stability boundaries of ballooning modes in circular tokamaks (open access)

Asymptotic stability boundaries of ballooning modes in circular tokamaks

The model ballooning mode equation of Connor, Hastie, and Taylor for large-aspect-ratio circular tokamaks is analyzed in the limit of large pressure gradient, and corresponding expressions for stability boundaries are derived. In particular, it is found that for a fixed radial wave number, there exists an infinite sequence of unstable bands, and that minimizing over the radial wave numbers leads to asymptotic merging between the neighboring bands.

Beam dynamics in the SLC final focus system (open access)

Beam dynamics in the SLC final focus system

The SLC luminosity is reached by colliding beams focused to about 2 ..mu..m transverse sizes. The Final Focus System (FFS) must enable, beyond its basic optical design, the detection and correction of errors accumulated in the system. In this paper, after summarizing the design, we review the sensitivity to such errors and the ability to correct them. The overall tuning strategy involves three phases: single beam spot minimization, steering the beams in collision and luminosity optimization with beam-beam effects.

Beamline considerations for a compact, high current, high power linear RF electron accelerator (open access)

Beamline considerations for a compact, high current, high power linear RF electron accelerator

A design for a compact, high current, high power linear electron accelerator using an rf power source is investigated. It consists of adjacent cavities into which rf power is injected and through which electron pulses pass. The source is assumed to be capable of delivering sufficient rf power to the desired location at the proper phase. Beamline issues such as cavity loading, energy extraction, longitudinal and transverse pulse focusing, and beam breakup are considered. A device which, given the required source, can deliver beam parameters comparable to existing induction accelerators but which is more than an order of magnitude smaller appears feasible.

Calculation of MCPR (minimum critical power ratio) for BWR transients using the BNL plant analyzer (open access)

Calculation of MCPR (minimum critical power ratio) for BWR transients using the BNL plant analyzer

The critical power ratio (CPR) is used for determining the thermal limits of boiling water reactors. In this study, critical power ratios for a series of transients run on the Brookhaven Plant Analyzer (BPA) (1) have been calculated. The transients include nominal base case simulations, simulations with variations in relief valve setpoints and the number of failed feedwater heaters, simulations at the 100% power, 75% flow point on the extended load line of the MEOD, and a simulation with partial feedwater heating. The plant represented with the BPA is a BWR/4 rated at 3293 MW with a 6.38 m (251'') vessel. Data were obtained by the Plant Analyzer Development Group at BNL from a variety of sources describing the Browns Ferry Plant.

CAVEAT calculations of shock interactions (open access)

CAVEAT calculations of shock interactions

CAVEAT is a computer code for calculating the time-varying fluid dynamics of several adjacent materials in two or three space dimensions. Using an extended Godunov technique and adaptive meshing, the code allows for large slippage at material interfaces. To exhibit the capability for calculating strong distortions we have performed a variety of calculations describing the interaction of shocks with rigid wedges, cylinders, and spheres and deformable cylindrical, spherical, and conical shells in two space dimensions. Comparison of the results with experimental data and analytical solutions demonstrates the considerable accuracy that can be expected from calculations with this code.
