Plant succession on disturbed sites in four plant associations in the Northern Mojave Desert( )

2 editions published in 1993 in English and held by 8 WorldCat member libraries worldwide

The US Department of Energy (DOE) is characterizing Yucca Mountain Nevada, as a potential site for long-term underground storage of high-level nuclear waste. DOE is committed to reclaim all lands disturbed by the project, and return them to a stable ecological state, with a composition and productivity similar to predisturbance conditions. A study was implemented to assess plant species which naturally invade disturbed sites in the Yucca Mountain Project Area. In 1991 and 1992 study plots were established on disturbed sites. Sites were characterized by disturbance type (i.e., road, drill pad, etc.), disturbance severity, vegetation association, time since abandonment, and topographic placement. Density of all perennial plant species was measured on disturbed and undisturbed plots. The species with the highest density in disturbed sites was Chrysothamnus teretifolia. This species was not a major contributor in undisturbed sites. In the undisturbed sites Ambrosia dumosa had the highest density of perennial plant species but was also high in density in the disturbance sites. Total species density was higher in undisturbed sites compared to disturbed sites. Plant species density analysis compared disturbed and undisturbed vegetation associations. Results will be used to design reclamation field trails and to finalize the Yucca Mountain Project Reclamation Implementation Plan
U-Series Disequilibra in Soils, Pena Blanca Natural Analog, Chihuahua, Mexico( )

1 edition published in 2006 in English and held by 5 WorldCat member libraries worldwide

The Nopal I uranium deposit located in the Sierra Pena Blanca, Mexico. The deposit was mined in the early 1980s, and ore was stockpiled close by. This stockpile area was cleared and is now referred to as the Prior High Grade Stockpile (PHGS). Some of the high-grade boulders from the site rolled downhill when it was cleared in the 1990s. For this study soil samples were collected from the alluvium surrounding and underlying one of these boulders. A bulk sample of the boulder was also collected. Because the Prior High Grade Stockpile had no ore prior to the 1980s a maximum residence time for the boulder is about 25 years, this also means that the soil was at background as well. The purpose of this study is to characterize the transport of uranium series radionuclides from ore to the soil. Transport is characterized by determining the activities of individual radionuclides and daughter to parent ratios. Isotopes of the uranium series decay chain detected include {sup 210}Pb, {sup 234}U, {sup 230}Th, {sup 226}Ra, {sup 214}Pb, and {sup 214}Bi. Peak areas for each isotope are determined using gamma-ray spectroscopy with a Canberra Ge (Li) detector and GENIE 2000 software. The boulder sample is close to secular equilibrium when compared to the standard BL-5 (Beaver Lodge Uraninite from Canada). Results for the soils, however, indicate that some daughter/parent pairs are in secular disequilibrium. These daughter/parent (D/P) ratios include {sup 230}Th/{sup 234}U, which is greater than unity, {sup 226}Ra/{sup 230}Th, which is also greater than unity, and {sup 210}Pb/{sup 214}Bi, which is less than unity. The gamma-ray spectrum for organic material lacks {sup 230}Th peaks, but contains {sup 234}U and {sup 226}Ra, indicating that plants preferentially incorporate {sup 226}Ra. Our results, combined with previous studies require multistage history of mobilization of the uranium series radionuclides. Earlier studies at the ore zone could limit the time span for mobilization only to a few thousand years. The contribution of this study is that the short residence time of the ore at the Prior High Grade Stockpile requires a time span for mobilization of 20-30 years
Effects of seedbed preparation, irrigation, and water harvesting on seedling emergence at the Nevada Test Site( )

1 edition published in 1993 in English and held by 4 WorldCat member libraries worldwide

Approximately 800 hectares on the US Department of Energy Nevada Test Site and vicinity are contaminated with plutonium. As part of a cleanup effort, both the indigenous vegetation and the top 5--10 cm of soil may be removed, and the soil may or may not be replaced. Technologies must be developed to stabilize and revegetate these lands. A study was developed to determine adaptable plant species, methods to prepare seedbeds for direct seeding and water harvesting, and proper irrigation rates. Plots were cleared of indigenous vegetation, and then prepared with various seedbed/water harvesting treatments including, pitting, land imprinting, and mulching. Other plots were treated with large water harvesting structures. Three irrigation treatments were superimposed over the seedbed/water harvesting treatments. Seedling emergence data was collected, and the treatment combinations compared. Supporting meteorological and soil data were collected with an automatic data-logger. Specific data included soil water data from all treatment combinations, precipitation, and air temperature. Irrigation did extend the period of available water approximately two to three weeks, but in a year of above average precipitation, this extension did not generally aid germination and emergence of seeded species, and only slightly increased densities of species from the native seedbank. With the exception of increased shrub seedling densities in desert strips, there were no strong seedbed preparation/water harvesting treatment effects. In years of above-average rainfall, mulching and water harvesting treatments, and irrigation may not be necessary to insure adequate germination and emergence of adapted perennial grasses, forbs, and shrubs in the Mojave/Great Basin Transition Desert
Corrective Action Investigation Plan : Roller Coaster Lagoons and North Disposal Trench, Tonopah Test Range, Revision 1( )

1.1 Purpose The purpose of this investigation is to collect data to confirm the presence or absence of contamination, evaluate the potential for contaminant migration, and select appropriate closure methods for these sites. The potential closure methods for these sites involve either clean closure, closure in place, or no further action. 1.2 Scope The scope of this investigation includes collecting surface and subsurface soil samples at the Roller Coaster Lagoons; and collecting surface soil samples at the North Disposal Trench and the small spill area associated with the Voluntary Cotiective Action (VCA) that was conducted in 1995
An aerial radiological survey of the neutron products company and surrounding area( )

1 edition published in 1994 in English and held by 4 WorldCat member libraries worldwide

An aerial radiological survey was conducted from November 1-10, 1993, over the Neutron Products Company and neighboring areas. The company, located in Dickerson, Maryland, has two major operations involving the radioisotope cobalt-60 (⁶°Co)-the manufacture of commercial ⁶°Co sources and the sterilization of medical products by exposure to radiation. The sterilization facility consists of two ⁶°Co sources with activities of approximately 500,000 and 1,500,000 Ci, respectively. The purpose of the aerial survey was to detect and document any anomalous gamma-emitting radionuclides in the environment which may have resulted from operations of the Neutron Products Company. The survey covered two areas: the first was a 6.5- by 6.5-kilometer area centered over the Neutron Products facility; the second area was a 2- by 2.5-kilometer region surrounding a waste pumping station on Muddy Branch in Gaithersburg, Maryland. This site is approximately fifteen kilometers southeast of the Neutron Products facility and was included because sanitary and other liquid waste materials from the plant site are being disposed of at the pumping station. Contour maps showing gamma radiation exposure rates at 1 meter above ground level, overlaid on an aerial photo of the area, were constructed from the data measured during the flights. The exposure rates measured within the survey regions were generally uniform and typical of rates resulting from natural background radiation. Only one area showed an enhanced exposure rate not attributable to natural background. This area, located directly over the Neutron Products facility, was analyzed and identified as ⁶°Co, the radioisotope used in the irradiation and source production operations conducted at the Neutron Products Company. The measurements over the Muddy Branch area in Gaithersburg were typical of natural background radiation and showed no evidence of ⁶°Co or any other man-made radionuclide

1 edition published in 1993 in English and held by 4 WorldCat member libraries worldwide

An aerial radiological survey of the Oak Ridge Reservation (ORR) and surrounding area in Oak Ridge, Tennessee, was conducted during the period March 30 to April 14,1992. The purpose of the survey was to measure and document the terrestrial radiological environment of the Oak Ridge Reservation for use in environmental management programs and emergency response planning. The aerial survey was flown at an altitude of 150 feet (46 meters) along a series of parallel lines 250 feet (76 meters) apart and included X-10 (Oak Ridge National Laboratory), K-25 (former Gaseous Diffusion Plant), Y-12 (Weapons Production Plant), the Freels Bend Area and Oak Ridge Institute for Science and Education, the East Fork Poplar Creek (100-year floodplain extending from K-25 to Y-12), Elza Gate (former uranium ore storage site located in the city of Oak Ridge), Parcel A, the Clinch River (river banks extending from Melton Hill Dam to the city of Kingston), and the CSX Railroad Tracks (extending from Y-12 to the city of Oak Ridge). The survey encompassed approximately 55 square miles (1 41 square kilometers) of the Oak Ridge Reservation and surrounding area
Yucca Mountain Biological Resources Monitoring Program. Progress report, January 1994--December 1994( )

1 edition published in 1995 in English and held by 4 WorldCat member libraries worldwide

The US Department of Energy (DOE) is required by the Nuclear Waste Policy Act of 1982 (as amended in 1987) to study and characterize the suitability of Yucca Mountain as a potential geological repository for high-level nuclear waste. During site characterization, the DOE will conduct a variety of geotechnical, geochemical, geological, and hydrological studies to determine the suitability of Yucca Mountain as a potential repository. To ensure that site characterization activities do not adversely affect the environment at Yucca Mountain, a program has been implemented to monitor and mitigate potential impacts and ensure activities comply with applicable environmental regulations. This report describes the activities and accomplishments of EG and G Energy Measurements, Inc. (EG and G/EM) from January 1994 through December 1994 for six program areas within the Terrestrial Ecosystem component of the environmental program for the Yucca Mountain Site Characterization Project (YMP): Site Characterization Effects, Desert Tortoises (Gopherus agassizii), Habitat Reclamation, Monitoring and Mitigation, Radiological Monitoring, and Biological Support
The influence of annual species composition and density on perennial seedling density in four plant communities in the Northern Mojave Desert( )

1 edition published in 1993 in English and held by 4 WorldCat member libraries worldwide

According to the Nuclear Waste Policy Act of 1982 (as amended in 1987), the US Department of Energy (DOE) must study and characterize Yucca Mountain as a potential site for long-term underground storage of high-level nuclear waste. Part of the overall site characterization program is to monitor potential impacts on the biological resources at Yucca Mountain. A part of the biological monitoring program, assessed vegetation parameters included density of annual and perennial seedlings. This data was used to evaluate: (1) seed germination and seed survival; and (2) if annual plant species density and cover influence perennial seedling survival. Twelve permanent 200 x 200-m, study plots were established in each of four vegetation associations present in the Yucca Mountain Project area. During the spring of 1992, 20 to 60, 1-m² randomly-located quadrats per study plot were measured for perennial seedling density, annual species density, and annual species composition. Perennial seedlings found in 1992 were relocated in the spring of 1993, and survival determined. Cover was measure in the spring of 1992. Annual plant density and cover was greatest in the Larrea-Lycium-Grayia vegetation association, and lowest in the Larrea-Ambrosia vegetation association. Annual seedling density had a negative exponential relationship with perennial seedling density in 1992. However, non-linear regression analysis indicated that 1992 annual seedling density had a greater impact on survival of pernnial seedlings from 1992 to 1993

Federal Radiological Monitoring and Assessment Center (FRMAC) overview of FRMAC operations( )

1 edition published in 1996 in English and held by 4 WorldCat member libraries worldwide

In the event of a major radiological emergency, 17 federal agencies with various statutory responsibilities have agreed to coordinate their efforts at the emergency scene under the umbrella of the Federal Radiological Emergency Response plan (FRERP). This cooperative effort will assure the designated Lead Federal Agency (LFA) and the state(s) that all federal radiological assistance fully supports their efforts to protect the public. The mandated federal cooperation ensures that each agency can obtain the data critical to its specific responsibilities. This Overview of the Federal Radiological Monitoring and Assessment Center (FRMAC) Operations describes the FRMAC response activities to a major radiological emergency. It also describes the federal assets and subsequent operational activities which provide federal radiological monitoring and assessment of the off-site areas. These off-site areas may include one or more affected states
Application of a geographic information system for radiologic emergency response( )

1 edition published in 1995 in English and held by 4 WorldCat member libraries worldwide

A geographic information system (GIS) is a multifunctional analytical tool that can be used to compile available data and derive information. A GIS is a computerized database management system for the capture, storage, retrieval, analysis, and display of spatial data. Maps are the most common type of spatial data, but any type of data that can be referenced by an x-y location or geographic coordinate can be used in a GIS. In a radiological emergency, it is critical that data of all types be rapidly compiled into a common format in order to make accurate observations and informed decisions. Developing a baseline GIS for nuclear facilities would offer a significant incentive for all organizations to contribute to and utilize this powerful data management tool. The system being developed could integrate all elements of emergency planning, from the initial protective actions based on models through the emergency monitoring phase, and finally ending with the complex reentry and recovery phase. Within the Federal Radiological Monitoring and Assessment Center (FRMAC), there is a continuing effort to improve the data management and communication process. To demonstrate the potential of GIS for emergency response, the system has been utilized in interagency FRMAC exercises. An interactive GIS system has been deployed and used to analyze the available spatial data to help determine the impact of a hypothetical radiological release and to develop mitigation plans. For this application, both hardcopy and real-time spatial displays were generated with the GIS. Composite maps with different sizes, scales, and themes were produced to support the exercises
CORRECTIVE ACTION DECISION DOCUMENT FOR AREA 9 UXO LANDFILL, TONOPAH TEST RNGE, CAU 453, REVISION 0, MARCH 1998( )

1 edition published in 1998 in English and held by 4 WorldCat member libraries worldwide

This Corrective Action Decision Document (CADD) has been prepared for the Area 9 Unexploded Ordnance (UXO) Landfill (Corrective Action Unit [CAU] 453) in accordance with the Federal Facility Agreement and Consent Order (FFACO) of 1996. Corrective Action Unit 453 is located at the Tonopah Test Range (TTR), Nevada, and is comprised of three individual landfill cells located northwest of Area 9. The cells are listed as one Corrective Action Site (CAS) 09-55-001-0952. The landfill cells have been designated as: Cell A9-1 Cell A9-2 Cell A9-3 The purpose of this CADD is to identify and provide a rationale for the selection of a recommended corrective action alternative for CAU 453. The scope of this CADD consists of the following tasks: Develop corrective action objectives. Identify corrective action alternative screening criteria. Develop corrective action alternatives. Perform detailed and comparative evaluations of the corrective action alternatives in relation to the corrective action objectives and screening criteria. Recommend and justify a preferred corrective action alternative for the CAU. In June and July 1997, a corrective action investigation was performed that consisted of activities set forth in the Corrective Action Investigation Plan (CAIP) (DOE/NV, 1997). Subsurface investigation of the soils surrounding the cells revealed no contaminants of concern (COCs) above preliminary action levels. The cell contents were not investigated due to the potential for live UXO. Details concerning the analytical and investigation results can be found in Appendix A of this CADD. Based on the potential exposure pathways, the following corrective action objectives have been identified for CAU 453: Prevent or mitigate human exposure to subsurface soils containing COCs, solid waste, and/or UXO. Prevent adverse impacts to groundwater quality. Based on the review of existing data, future land use, and current operations at the TTR, the following alternatives have been developed for consideration at the Area 9 UXO Landfill CAU: Alternative 1 - No Further Action Alternative 2 - Closure in Place by Administrative Controls Alternative 3 - Closure in Place by Capping Alternative 4 - Clean Closure by Removal The corrective action alternatives were evaluated based on four general corrective action standards and five remedy selection decision factors. Based on the results of this evaluation, Alternative 2, Closure in Place by Administrative Controls, was selected as the preferred corrective action alternative. The preferred corrective action alternative was evaluated on its technical merits, focusing on performance, reliability, feasibility, and safety. The alternative was judged to meet all requirements for the technical components evaluated and to represent the most cost-effective corrective action. The alternative meets all applicable state and federal regulations for closure of the site and will reduce potential future exposure pathways to the contents of the landfill. During corrective action implementation, this alternative will present minimal potential threat to site workers. However, appropriate health and safety procedures will be developed and implemented
An aerial radiological survey of the southwest drainage basin area of the Savannah River Site( )

1 edition published in 1994 in English and held by 4 WorldCat member libraries worldwide

An aerial radiological survey was conducted over a 106-square-mile area of the Savannah River Site (SRS), formerly the Savannah River Plant. The survey was conducted from August 24 through September 8, 1988, to collect baseline radiological data over the area. Both natural and man-made gamma emitting radionuclides were detected in the area. The detected man-made sources were confined to creeks, branches, and SRS facilities in the surveyed area and were a result of SRS operations. Naturally-occurring radiation levels were consistent with those levels detected in adjacent areas during previous surveys. The annual dose levels were within the range of levels found throughout the United States
Thermographic-phosphor temperature measurements : Commercial and defense-related applications( )

1 edition published in 1994 in English and held by 4 WorldCat member libraries worldwide

This paper is a review of a diverse set of applications of the thermographic-phosphor (TP) method for measuring temperatures remotely. The TP method is useful in hostile and/or inaccessible environments where no other known method works. It is highly accurate, nonintrusive, durable, conceptually simple, covers an unprecedented temperature range (0 K to>1200 K), can measure temperature at a single point or over an entire surface, and can make static, steady-state, or very high speed dynamic measurements. The TP method can also be used to make leadless, remotely interrogated heat-flux gauges that can nonintrusively measure spatial distributions of heat flux over arbitrarily large areas with high resolution. The applications described include measurements in gas centrifuges, motors, variable-area ejectors, rotors and stators in gas turbines, and others. The authors also briefly discuss heat-flux gauges and their applications

The Federal Radiological Monitoring and Assessment Center (FRMAC) conducted a three day training drill May 17 through May 19, 1994 at the Nevada Test Site (NTS). The drill was designed to provide training to field monitors and data assessors who would respond to a major radiological emergency. The drill was named ''HANDSHAKE ONE'' to symbolize the strong FRMAC relationship between the federal and state radiological agencies
X-Ray Shawdowgraph Camera Design( )

1 edition published in 1999 in English and held by 4 WorldCat member libraries worldwide

An imagining camera that is used with X-Ray radiography systems in high explosive experiments has been built and fielded. The camera uses a 40mm diameter Micro-Channel Plate Itensifier (MCPI) for optical gain and photographic film for image recording. In the normal location of the X-ray film pack, a scintillating screen is placed instead. The camera system views the screen and records the image. The sensitivity of the MCPI to light makes the camera design sensitive to small details that a film pack does not need to consider. The X-ray image recording system was designed and bulit for situations where the film pack of the X-ray shadowgraph is not retrievable after the experiment. The system has been used in a number of experiments
