Weight Losses of Marble and Limestone Briquettes Exposed to Outdoor Environments in the Eastern United States

Description: Weight losses of marble and limestone samples exposed to outdoor environments at field sites in the eastern United States have been monitored in studies initiated in 1984. The procedures are described, and the results are tabulated and discussed. A rate of marble loss approximately equivalent to 16 micrometers of surface recession per year was found in North Carolina, and losses of this order were also observed in New Jersey, New York, and Washington, DC. Limestone weight losses were much highe… more

A comparison of atmospheric transport considerations in eastern and western oil shale operations

Description: Atmospheric transport represents one of the critically important pathways for the distribution of pollutants from any oil shale operation. Our experience in studying eastern and western shale resources and operation suggest many common features regarding the atmospheric domain, but also many significant differences. Any issue of atmospheric transport and dispersion can be broken down into major elements: source factors which include the spatial and temporal distribution of pollutant sources as … more

Measurement and modeling of external radiation during 1985 from LAMPF (Los Alamos Meson Physics Facility) emissions

Description: An array of three portable, pressurized ionization chambers (PICs) continued to measure external radiation levels during 1985 caused by radionuclides emitted from the Los Alamos Meson Physics Facility (LAMPF). A Gaussian-type atmospheric dispersion model, using onsite meteorological and stack release data, was tested during this study. A more complex finite model, which takes into account the contribution of radiation at a receptor from different locations of the passing plume, was also tested.… more

Variability of wind power near Oklahoma City and implications for siting of wind turbines

Description: Data from five sites near Oklahoma City were examined to assess wind power availability. Wind turbines of identical manufacture were operated at three of the sites, one of which was also equipped with anemometers on a 100-ft tower. Comprehensive anemometric data were available from the other two sites. The study indicates that the average wind speed varies substantially over Oklahoma's rolling plains, which have often been nominally regarded as flat for purposes of wind power generation. Averag… more

Protective action alternatives for accidents at nuclear power plants

Description: Protective action calculations have been performed for five different light water reactors (LWRs) and containment designs using high and low fission product releases for early and late containment failures for each plant. These fission product release estimates were obtained from studies performed for the recently published ''Reactor Risk Reference Document'' (NUREG-1150). Five protective actions were considered for the risks of exceeding various dose levels to the red marrow versus centerline … more

Wake effects in a Fayette 95-IIS wind turbine array

Description: A group of 35 wind turbines on the Castello Ranch in Altamont Pass, California, was investigated to quantify array wake effects (losses in energy production due to operation of upwind turbines) and the factors influencing them. Approximately 65 hours of field measurements were made in summer 1986, with turbine energy production and wind velocity data recorded for various scenarios of array operation. Customized software and hardware were developed and installed by Fayette to facilitate these me… more

User's manual for the convective cloud module version 1. 0. [RADM; RSM]

Description: This manual describes a convective cloud model and provide guidance for users. The convective cloud model is assumed to provide a time-averaged distribution of data from a population of precipitating, convective clouds in different stages of development. This model was designed to characterize a scavenging environment using meteorological conditions provided by a regional-scale meteorological code. This meteorological code explicitly simulates processes related to cloud microphysics. The cloud … more

Transport of breeder reactor-fire-generated sodium oxide aerosols for building-wake-dominated meteorology

Description: This report describes the methodology used and results obtained in efforts to estimate the sodium aerosol concentrations at air intake ports of a liquid-metal cooled, fast-breeder nuclear reactor. An earlier version of this methodology has been previously discussed (Fields and Miller, 1985). A range of wind speeds from 2 to 10 m/s is assumed, and an effort is made to include building wake effects which, in many cases, dominate the dispersal of aerosols near buildings. For relatively small relea… more

Update on the meso-microscale meteorological hierarchy

Description: SIGTRA is designed to define the height of the material layer and provide interpolated mass and energy fluxes to VARYME. It also provides interpolated winds, temperatures, and potential densities at levels within the material layer. VARTRA uses similarity theory surface energy budget considerations, and the VARYME solutions to perturb the SIGMET profiles. It is the principal vehicle for converting the VARYME solutions into wind and temperature profiles and for incorporating the effects of local… more

Environmental monitoring report for Calendar Year 1986

Description: The results of the 1986 environmental monitoring program for the Princeton Plasma Physics Laboratory (PPPL) are presented and discussed. Two of three large tokamak machines, the Princeton Large Torus (PLT) and the Tokamak Fusion Test Reactor (TFTR) were in operation during the year. The Princeton Beta Experiment (PBX) was shut down in December 1985 to undergo major modifications, and will recommence operations in 1987. PLT was shut down in December 1986. In addition, the S-1 Spheromak and the R… more

An analysis of evacuation options for nuclear accidents

Description: In this report we consider the threat posed by the accidental release of radionuclides from a nuclear power plant. The objective is to establish relationships between radiation dose and the cost of evacuation under a wide variety of conditions. The dose can almost always be reduced by evacuating the population from a larger area. However, extending the evacuation zone outward will cause evacuation costs to increase. The purpose of this analysis was to provide the Environmental Protection Agency… more

Description of the Mountain Cloud Chemistry Program version of the PLUVIUS MOD 5. 0 reactive storm simulation model

Description: Damage to forest ecosystems on mountains in the eastern United States has prompted a study conducted for the US Environmental Protection Agency's Mountain Cloud Chemistry Program (MCCP). This study has led to the development of a numerical model called MCCP PLUVIUS, which has been used to investigate the chemical transformations and cloud droplet deposition in shallow, nonprecipitating orographic clouds. The MCCP PLUVIUS model was developed as a specialized version of the existing PLUVIUS MOD 5… more

Hanford Meteorological Station computer codes: Volume 3, The TANK computer code

Description: At the end of each graveyard shift the Hanford Meteorological Station (HMS), operated by Pacific Northwest Laboratory, issues a forecast of eight hourly average wind speeds and wind gusts for the 50-ft level. The Hanford Waste Management crew uses this forecast, called the tank farm forecast, to schedule daily work loads. The forecast covers an 8-hour period (0800 to 1600 during Pacific Standard Time (PST) or 0700 to 1500 during Pacific Daylight Time (PDT)) and the day-shift forecaster may modi… more

Application and sensitivity studies of the orographic cloud model MCCP (Mountain Cloud Chemistry Program) PLUVIUS

Description: A special MCCP version of the PLUVIUS MOD 5.0 reactive storm model (MCCP PLUVIUS) was applied to conditions representative of Mt. Mitchell, North Carolina. Tests were also conducted to determine the sensitivity of the model to various meteorological and chemical parameters. Results of the modeling investigation indicate that aqueous concentrations and deposition fluxes of pollutants are location dependent. The greatest concentrations occur at the edges of the cloud, where the liquid water conte… more
