Ship-produced cloud line of 13 July 1991

Description: Steaming ships can produce long linear cloud lines in regions of fog and broken stratus as well as in marine stratus layers. The lines are not always detected in 0.63 [mu]m satellite images, but are often detected in the corresponding 3.7 [mu]m images because the lines contain smaller and more numerous droplets than the stratus in which they are embedded as deduced by Coakley, et al. and measured by Radke, et al. They postulate cloud condensation nuclei (CCN) from steaming ships produced the mo… more

A two-dimensional simulation of tritium transport in the vadose zone at the Nevada Test site

Description: The site of a 0.75-kiloton underground nuclear explosion, the Cambric event, was selected for the study of radionuclide transport in the hydrologic environment. Water samples from RNM-2S, a well located 91 m from Cambric, have been analyzed for tritium and other radionuclides since the initiation of pumping. Water from RNM-2S flows to Frenchman Lake via an unlined canal. Flume data indicate canal transmission losses of approximately 2m{sup 3}/day/meter of canal. To determine if infiltrating can… more

Origin of elevated water levels encountered in Pahute Mesa emplacement boreholes: Preliminary investigations

Description: The presence of standing water well above the predicted water table in emplacement boreholes on Pahute Mesa has been a recurring phenomenon at the Nevada Test Site (NTS). If these levels represent naturally perched aquifers, they may indicate a radionuclide migration hazard. In any case, they can pose engineering problems in the performance of underground nuclear tests. The origin of these elevated waters is uncertain. Large volumes of water are introduced during emplacement drilling, providing… more

The origin of elevated water levels in emplacement boreholes, Pahute Mesa, Nevada Test Site: A numerical study

Description: The origin of elevated water levels in emplacement boreholes at Pahute Mesa, Nevada Test Site, is uncertain. If the water is from naturally perched aquifers, then presumed ``above water table`` weapons tests may directly impact the groundwater quality. The purpose of this study is to determine the probable source of the elevated water in boreholes by comparing modeled seepage of infiltrated drilling fluids, and the seepage from a simulated naturally perched aquifer with the observed water level… more

Groundwater flow near the Shoal Site, Sand Springs Range, Nevada: Impact of density-driven flow

Description: The nature of flow from a highland recharge area in a mountain range in north-central Nevada to discharge areas on either side of the range is evaluated to refine a conceptual model of contaminant transport from an underground nuclear test conducted beneath the range. The test, known as the Shoal event, was conducted in 1963 in granitic rocks of the Sand Springs Range. Sparse hydraulic head measurements from the early 1960s suggest flow from the shot location to the east to Fairview Valley, whi… more

Development of the town data base: Estimates of exposure rates and times of fallout arrival near the Nevada Test Site

Description: As part of the U.S. Department of Energy`s Off-Site Radiation Exposure Review Project, the time of fallout arrival and the H+12 exposure rate were estimated for populated locations in Arizona, California, Nevada, and Utah that were affected by fallout from one or more nuclear tests at the Nevada Test Site. Estimates of exposure rate were derived from measured values recorded before and after each test by fallout monitors in the field. The estimate for a given location was obtained by retrieving… more

Annotated bibliography of literature relating to wind transport of plutonium-contaminated soils at the Nevada Test Site

Description: During the period from 1954 through 1963, a number of tests were conducted on the Nevada Test Site (NTS) and Tonopah Test Range (TTR) to determine the safety of nuclear devices with respect to storage, handling, transport, and accidents. These tests were referred to as ``safety shots.`` ``Safety`` in this context meant ``safety against fission reaction.`` The safety tests were comprised of chemical high explosive detonations with components of nuclear devices. The conduct of these tests resulte… more

Some statistical aspects of characterizing the distribution of radionuclides in the environment

Description: A radiological characterization was performed at the former Kellex site, the first pilot uranium-diffusion plant, in Jersey City, New Jersey to determine if there were any contaminated regions containing 40 pCi/g or more of /sup 238/U in the top 20 cm of soil over a 400 m/sup 2/ area. As a result of this radiological survey, final decisions would be made about the need for remedial action (cleanup) and the suitability for unrestricted use of the site. This paper describes the development and th… more

Thermodynanmic relations between selected parameters describing unsaturated flow

Description: The first law of thermodynamics is applied to unsaturated flow by replacing the usual PdV term (P is pressure and V is volume) for chemical system which appears there by psi d theta/sub s/ (phi is matric suction and theta/sub s/ is the degree of saturation). If the assumption is made that hysteretic behavior of the moisture characteristic can be ignored, all the usual thermodynamic relations can be derived in which P is replaced by phi and V is replaced by theta/sub s/ and the various thermodyn… more
