Protective Action Evaluator for Chemical Emergencies: A user's manual (MS-DOS reg sign Version 1. 0) (open access)

Protective Action Evaluator for Chemical Emergencies: A user's manual (MS-DOS reg sign Version 1. 0)

The protective action evaluator for chemical emergencies (PAECE) is a package of computer programs developed to simulate an emergency response to airborne release of chemical agents. This user's manual documents the use of PAECE in the evaluation of chemical agent emergencies in areas potentially affected by the Chemical Stockpile Emergency Planning Program (CSEPP). This research documents the development and use of a method for the evaluation of protective action alternatives in conjunction with potential chemical agent emergencies. The user's manual highlights the development of the PAECE model, the selection of appropriate parameters to represent various scenarios, generate results and interpret them in the analysis of protective action alternatives during the planning and preparedness phases of the CSEPP. The PAECE model is designed to evaluate protective actions in the context of potential accidents, the emergency management systems required to implement protective actions, and the anticipated consequences for human receptors. The implications and uncertainties of the model are discussed to provide potential users with insight into the use, limitations, and uncertainties associated with evaluating the effectiveness of protective action alternatives. While PAECE represents a unique and powerful tool to evaluate protective actions, the user must exercise caution when interpreting the results to …

Quark mass difference and the origin of charge symmetry breaking (open access)

Quark mass difference and the origin of charge symmetry breaking

Evidence for charge symmetry breaking in nuclear and particle physics in presented and it is shown that all of the observed effects can be explained by the mass and electric charge difference between d and u quarks. While hadron masses depend on the sum of the quark masses, charge symmetry breaking effects depend on the difference between d and u quark masses providing a new quark mass relation. 25 refs., 3 tabs.

Radiative Properties of Ash and Slag. Final Report (open access)

Radiative Properties of Ash and Slag. Final Report

The objective of this program has been to make laboratory measurements of the radiative properties of ash and slag deposits that have been extracted from combustion devices. The program has resuited in measurements of radiative properlies of materials at high temperatures made by a technique employing a sample heatng deVice that is coupled to a FT-IR spectrometer to measure emission, directional-hemispherical transmission, and directional-hemispherical reflection of a sample. By this technique, the temperature at the measurement point and the spectral emittance (emissivity) of the surface are both obtained. These measurements are then related to the physical and chemical properties of the surface to determine what controls the radiative properlies. The measurements have shown that the physical state of a deposit (i.e. fused, sintered or packed particles) greatly influence the measured spectral emittance. The main accomplishments of the program are as follows: (1) Demonstration of measurement technique validation. (2) Measurements of spectral emittance for deposit samples as a function of temperature and morphology. (3) Accurate calculations of the optical properties of smooth and sintered surfaces based on the material`s complex Index of refraction and the surface morphology.

Radiological survey of the former Aeroprojects Facility, West Chester, Pennsylvania (open access)

Radiological survey of the former Aeroprojects Facility, West Chester, Pennsylvania

The former Aeroprojects, Incorporated, Facility is located at 200-T East Rosedale Avenue, West Chester, Pennsylvania. The facility was under contract to the Atomic Energy Commission (AEC) beginning in 1951 to investigate the use of ultrasonic energy in a variety of manufacturing procedures. An unknown quantity of alloys and compounds of aluminum, beryllium, mercury, thorium, and uranium were used on the site. In the mid-1960s, work for the AEC tapered off and Aeroprojects began doing R D under other government contracts. It is the policy of the US Department of Energy (DOE) to verify that radiological conditions at such sites or facilities comply with current DOE guidelines. Therefore, at the request of DOE, a radiological survey of this site was conducted in May 1988. The survey included a gamma scan of the interior of the building that had been used during the contract work and the area outdoors immediately adjacent to the building. The survey results show that all gamma exposure rates approximated typical background levels found in the southeastern Pennsylvania area and, furthermore, were well within the DOE guideline. However, recently discovered information suggests that small amounts of radioactive residuals may have been buried on site. The areas where these …

RCRA closure plan for underground storage tank 105-C (open access)

RCRA closure plan for underground storage tank 105-C

A Reactor Department program for repairing heat exchangers created a low level radioactive waste, which was held in underground storage tank (UST) 105-C, hereafter referred to as the tank. According to Procedures used at the facility, the waste`s pH was adjusted to the 8.0--12.0 range before shipping it to the SRS Waste Management Department. For this reason, area personnel did not anticipate that the waste which is currently contained in the tank would have corrosive hazardous characteristic. However, recent analysis indicates that waste contained in the tank has a pH of greater than 12.5, thereby constituting a hazardous waste. Because the Department of Energy-Savannah River Office (DOE-SR) could not prove that the hazardous waste had been stored in the tank for less than 90 days, the State of South Carolina Department of Health and Environmental Control (SCDHEC) alleged that DOE-SR was in violation of the 1976 Code of Laws of South Carolina. As agreed in Settlement Agreement 90-74-SW between the DOE and SCDHEC, this is the required closure plan for Tank 105-C. The purpose of this document is to present SCDHEC with an official plan for closing the underground storage tank. Upon approval by SCDHEC, the schedule for closure will …

A real-time digital control, data acquisition and analysis system for the DIII-D multipulse Thomson scattering diagnostic (open access)

A real-time digital control, data acquisition and analysis system for the DIII-D multipulse Thomson scattering diagnostic

A VME-based real-time computer systems for laser control, data acquisition and analysis for the DIII-D multipulse Thomson scattering diagnostic is described. The laser control task requires precise timing of up to 8 Nd:YAG lasers, each with an average firing rate of 20 Hz. A cpu module in real-time multiprocessing computer system will operate the lasers with evenly staggered laser pulses or in a burst mode'', where all available (fully charged) lasers can be fired at 50--100 {mu}sec intervals upon receipt of an external event trigger signal. One of more cpu modules, along with a LeCroy FERA (Fast Encoding and Readout ADC) system, will perform real-time data acquisition and analysis. Partial electron temperature and density profiles will be available for plasma feedback control within 1 msec following each laser pulse. The VME-based computer system consists of 2 or more target processor modules (25 MHz Motorola 68030) running the VMEexec real-time operating system connected to a Unix based host system (also a 68030). All real-time software is fully interrupt driven to maximize system efficiency. Operator interaction and (non real-time) data analysis takes place on a MicroVAX 3400 connected via DECnet. 17 refs., 1 fig.

Recent developments in heavy flavor theory (open access)

Recent developments in heavy flavor theory

Isgur and Wise consider the limit of QCD in the formal limit when the masses M{sub c}, M{sub b},{hor ellipsis}are taken to infinity with, say, the ratios held fixed. In such a limiting situation the theory still exists. The situation is similar to quantum electrodynamics of atoms when nuclear masses are set to infinity; nothing terrible happens. But in this limit theoretical predictions for weak matrix elements greatly simplify, and it is the feature which makes the approach potentially interesting. And it is important to stress that the limiting theory is not a nonrelativistic limit; relativistic effects can be and are included. This report discusses their work further.

Reductive mobilization of oxide-bound metals: The role of reductant capacity and reductant reactivity in determining mobilization rates in soils and sediments (open access)

Reductive mobilization of oxide-bound metals: The role of reductant capacity and reductant reactivity in determining mobilization rates in soils and sediments

We seek to identify environmental factors that exert a decisive influence on the mobilization of oxide-bound toxic metals in soils, sediments, and aquifers. Our objective is to examine how the complexant and reductant characteristics of organic compounds found in contaminated aquatic environments influence this mobilization process. Laboratory experiments begin by allowing toxic metals (Co, Ni, Pb, Cu) to adsorb onto host oxide phases (particulate MnO{sub 2} and FeOOH) for a period of 17 hours. Dissolved metal concentrations are then monitored after the addition of low molecular weight reference compounds (such as oxalate, malonate, and citrate) or natural organic matter. A variety of phenomena have been observed. Oxalate, for example, acts as a complexant at pH 6, solubilizing adsorbed Cu and Ni while leaving the MnO{sub 2} host phase intact. At pH 4, oxalate acts as both a complexant and reductant, causing solubilization of adsorbed Cu and Ni, and the MnO{sub 2} host phase. When toxic metals are equilibrated with NOM from the Great Dismal Swamp before MnO{sub 2} addition, the extent of adsorption is less than in NOM-free suspensions. As the host MnO{sub 2} phase is dissolved, the extent of toxic metal adsorption changes little. 4 refs., 8 figs., 1 …

Relativistic heavy ion fragmentation at HISS (Heavy Ion Spectrometer System) (open access)

Relativistic heavy ion fragmentation at HISS (Heavy Ion Spectrometer System)

An experiment was conducted at the Lawrence Berkeley Laboratory to measure projectile fragmentation of relativistic heavy ions. Charge identification was obtained by the use of a Cerenkov Hodoscope operating above the threshold for total internal reflection, while velocity measurement was performed by use of a second set of Cerenkov radiators operating at the threshold for total internal reflection. Charge and mass resolution for the system was {sigma}{sub Z} = 0.2 e and {sigma}{sub A} = 0.2 u. Measurements of the elemental and isotopic production cross sections for the fragmentation of {sup 40}Ar at 1.65{center dot}A GeV have been compared with an Abrasion-Ablation Model based on the evaporation computer code GEMINI. The model proves to be an accurate predictor of the cross sections for fragments between Chlorine and Boron. The measured cross section were reproduced using simple geometry with charge dispersions induced by zero-point vibrations of the giant dipole resonance for the prompt abrasion stage, and injecting an excitation energy spectrum based on a final state interaction with scaling factor E{sub fsi} = 38.8 MeV/c. Measurement of the longitudinal momentum distribution widths for projectile fragments are consistent with previous experiment and can be interpreted as reflecting the Fermi momentum distribution in …

Remote replacement of Materials Open-Test Assembly specimens at the FFTF IEM cell

The Fast Flux Test Facility (FFTF) Interim Examination and Maintenance (IEM) Cell is used for the remote disassembly of irradiated fuel and material experiments. Materials Open-Test Assemblies (MOTA) are brought to the IEM Cell where their outer ducts are removed, exposing the test train for material-specimen removal. The specimens are shipped to the materials laboratory for sorting. Some are selected for testing while the rest, along with new specimens, are loaded in new specimen holders and returned within ten days to the IEM Cell where they are placed in the test train of new MOTA vehicles. Installation of the outer ducts readies the MOTA's for further specimen irradiation. This presentation discusses remote equipment and techniques used in this process. 11 figs.

Repository relevant testing applied to the Yucca Mountain Project (open access)

Repository relevant testing applied to the Yucca Mountain Project

The tuff beds of Yucca Mountain, Nevada, are currently being investigated as a site for the disposal of high-level nuclear waste in an underground repository. If this site is found suitable, the repository would be located in the unsaturated zone above the water table, and a description of the site and the methodology of assessing the performance of the repository are described in the Site Characterization Plan (SCP). While many factors are accounted for during performance assessment, an important input parameter is the degradation behavior of the waste forms, which may be either spent fuel or reprocessed waste contained in a borosilicate glass matrix. To develop the necessary waste form degradation input, the waste package environment needs to be identified. This environment will change as the waste decays and also is a function of the repository design which has not yet been finalized. At the present time, an exact description of the waste package environment is not available. The SCP does provide an initial description of conditions that can be used to guide waste form evaluation. However, considerable uncertainty exists concerning the conditions under which waste form degradation and radionuclide release may occur after the waste package containment barriers are …

Research on stable, high-efficiency, large-area amorphous silicon based modules -- Task B (open access)

Research on stable, high-efficiency, large-area amorphous silicon based modules -- Task B

This report documents progress in developing a stable, high- efficiency, four-terminal hybrid tandem module. The module consists of a semi-transparent, thin-film silicon:hydrogen alloy (TFS) top circuit and a copper indium diselenide (CuInSe{sub 2}) bottom circuit. Film deposition and patterning processes were successfully extended to 0.4-m{sup 2} substrates. A 33.2-W (8.4% efficient) module with a 3970-cm{sup 2} aperture area and a white back reflector was demonstrated; without the back reflector, the module produced 30.2 W (7.6% efficient). Placing a laminated, 31.6-W, 8.1%-efficient CuInSe{sub 2} module underneath this TFS module, with an air gap between the two, produces 11.2 W (2.9% efficient) over a 3883-cm{sup 2} aperture area. Therefore, the four-terminal tandem power output is 41.4 W, translating to a 10.5% aperture-area efficiency. Subsequently, a 37.8-W (9.7% aperture-area efficiency) CuInSe{sub 2} module was demonstrated with a 3905-cm{sup 2} aperture area. Future performances of single-junction and tandem modules of this size were modeled, and predicted power outputs exceed 50 W (13% efficient) for CuInSe{sub 2} and 65 W (17% efficient) for TFS/CuInSe{sub 2} tandem modules.

The residual tune splitting in the presence of linear coupling (open access)

The residual tune splitting in the presence of linear coupling

The presence of random skew quadrupole field errors will couple the x and y motions. The x and y motions are then each given by the sum of 2 normal modes with the tunes {nu}{sub 1} and {nu}{sub 2}, which may differ appreciably from {nu}{sub x} and {nu}{sub y}, the unperturbed tunes. This is often called tune splitting. This tune splitting may be large in proton accelerators using superconducting magnets, because of the relatively large random skew quadrupole field errors that are expected in these magnets. This tune splitting has been studied in the RHIC accelerator. A correction system has been developed for correcting this large tune splitting which uses two families of skew quadrupole correctors. It has been found that this correction system corrects most of the large tune splitting, but a residual tune splitting remains that is still appreciable. RHIC has to operate within a box in tune space whose width is {Delta}{nu} = 33 {times} 10{sup {minus}3} in order to avoid all resonances which are tenth order or less. It appears desirable to correct the tune splitting to a level which is much smaller than 33 {times} 10{sup {minus}3}. The residual tune splitting that remained after correction …

Results of the DF-4 BWR (boiling water reactor) control blade-channel box test

The DF-4 in-pile fuel damage experiment investigated the behavior of boiling water reactor (BWR) fuel canisters and control blades in the high temperature environment of an unrecovered reactor accident. This experiment, which was carried out in the Annular Core Research Reactor (ACRR) at Sandia National Laboratories, was performed under the USNRC's internationally sponsored severe fuel damage (SFD) program. The DF-4 test is described herein and results from the experiment are presented. Important findings from the DF-4 test include the low temperature melting of the stainless steel control blade caused by reaction with the B{sub 4}C, and the subsequent low temperature attack of the Zr-4 channel box by the relocating molten blade components. Hydrogen generation was found to continue throughout the experiment, diminishing slightly following the relocation of molten oxidizing zircaloy to the lower extreme of the test bundle. A large blockage which was formed from this material continued to oxidize while steam was being fed into the the test bundle. The results of this test have provided information on the initial stages of core melt progression in BWR geometry involving the heatup and cladding oxidation stages of a severe accident and terminating at the point of melting and relocation of …

Results of the preliminary radiological survey at B and T Metals, 425 West Town Street, Columbus, Ohio (CO001)

As part of the Formerly Utilized Sites Remedial Action Program (FUSRAP), the US Department of Energy (DOE) is implementing a radiological survey program to determine the radiological conditions at sites that were formerly used by the department's predecessor agencies. The preliminary radiological survey discussed in this report for the B T Metals site in Columbus, Ohio, is part of the FUSRAP effort and was conducted at the request of DOE by members of the Measurement Applications and Development Group of Oak Ridge National Laboratory in 1988 and 1989. In the 1940s the B T Metals site was used to provide extrusion of uranium billets into rods in support of the Manhattan Engineer District (MED) operations. The preliminary radiological survey included a surface gamma scan, collection of dust, debris, and soil samples, measurement of direct and transferable alpha and beta-gamma activity, and air sampling. Results of this radiological assessment indicate that the property contains residual radioactivity from MED activities in concentrations that exceed remedial action guidelines. 8 refs., 8 figs., 6 tabs.
