Evaluations of alternatives for management of INEL transuranic waste

Description: The results of studies to identify and evaluate alternatives for long-term management of transuranic-contaminated waste at the Idaho National Engineering Laboratory are discussed. Three processing approaches have been studied: incineration; compaction and immobilization; and repackaging only. Four locations and four methods have been identified for possible onsite disposal of retrieved waste.

Risk evaluations of transuranic waste at the Idaho National Engineering Laboratory

Description: Approximately 75% of the defense low-level transuranic (TRU) waste stored in the United States and 25% of the buried TRU waste is located at the Idaho National Engineering Laboratory (INEL). Studies have been performed to identify and evaluate technical alternatives for the long-term management of this waste. (The alternatives range from leaving the waste in place as is to reviewing, processing, and shipping it to an offsite geological repository.) Among the evalations that have been performed … more

Time rate collision matrix

Description: The collision integral terms in Boltzmann equation are reformulated numerically leading to the substitution of the multiple integrals with a multiplicative matrix of the two colliding species velocity distribution functions which varies with the differential collision cross section. A matrix of lower rank may be constructed when one of the distribution functions is specified, in which case the matrix elements represent kinetic transition probabilities in the velocity space and the multiplicatio… more

Effect of neutral particles on anomalous skin current in tokamaks

Description: The anomalously rapid skin current relaxation observed in some experiments may be explained by any mechanism which cools the electrons thus increases the resistivity and limits the current increase in the plasma boundary, such as enhanced ion conduction, loss of high energy tail electrons or influx of cold neutrals. The current penetration into the plasma and the evolution of the electron temperature from hollow to central peaked radial profile are evaluated for a PLT (Princeton Large Torus) ex… more

MEASUREMENT OF SURFACE AREA OF URANIUM DIOXIDE POWDER AND SINTERED PELLETS

Description: The surface areas of sintered uranium dioxide pellets (individual pellets ranging from 50 to 2000 cm/sup 2/) were measured with a precision of 1.3% and a reproducibility of about 4% with a BET adsorption apparatus, using krypton as the adsorbate. Powder samples (10 to 50 mg) of uranium dioxide, anatase, zirconia, and ceria were measured with a precision of 0.5% and a reproducibility of about 3%. An excellent correlation was found between the surface area and the average particle diameter, as me… more

Vector network analyzer techniques to measure WR340 waveguide windows.

Description: In its fundamental form, network analysis involves the measurement of incident, reflected, and transmitted waves that travel along transmission lines. Measuring both magnitude and phase of components is important for several reasons. First, both measurements are required to fully characterize a linear network and ensure distortion-free transmission. To design effective matching networks, complex impedances must be measured. In the development of computer-aided-design (CAD) circuit simulation pr… more

Community relations for the transport of TMI-2 core debris

Description: This paper describes community relations for the transport of Three Mile Island Unit 2 core debris, before and during the first two years of the campaign. The author defines community relations as interactions with groups or individuals to influence public perception. Members of Congress, state and local officials, news media, special interest groups, and private citizens are included in the definition of community. The paper discusses issues of concern to the community, level of interest gener… more

Mode identification and cavity stretching for the prototype storage ring cavity

Description: The Advanced Photon Source (APS) storage ring uses single cell cavities. As described in the paper ``Coupled Bunch Instabilities in the APS Ring`` by L. Emery, several of the higher order modes (HOM) in these cavities cause instability thresholds below the desired operating level. In order to clearly identify these modes, an experimental method of measuring the fields is necessary. A well- known technique is measurement with probes or loops extending in from the walls, but this cannot be used i… more

Stress, seismicity and structure of shallow oil reservoirs of Clinton County, Kentucky. Final report

Description: Between 1993 and 1995 geophysicists of the Los Alamos National Laboratory, in a project funded by the US Department of Energy, conducted extensive microseismic monitoring of oil production in the recently discovered High Bridge pools of Clinton County and were able to acquire abundant, high-quality data in the northern of the two pools. This investigation provided both three-dimensional spatial and kinetic data relating to the High Bridge fracture system that previously had not been available. … more

Labeling of blood cells with /sup 99m/Tc

Description: Erythrocytes, leukocytes, and tumor cells were labeled with /sup 99m/Tc to take advantage of the ideal physical properties of /sup 99m/Tc. Clinical studies indicate that labeled erythrocytes can be used to obtain improved vascular and splenic imaging as well as reliable red cell volumes. The erythrocytes have been labeled with and without the use of an added reducing agent. Two methods of adding the reducing agent stannous chloride have been proposed which differ in the order of addition of the… more

The Advanced Photon Source linac modulators PSpice simulation and upgrade.

Description: The APS linac modulators provide DC pulses to Thales 35/45-MW klystrons. The modulators are pulse forming network (PFN)-type pulsers with EMI 40-kV switch-mode charging supplies. The PFN consists of two 8-cell lines connected in parallel. EEV CX1836A thyratrons are used as discharge switches. The PSpice simulation of the modulators using OrCAD release 9.1 made it possible to find appropriate parameters of RC circuits that reduce high-frequency ringing of the pulse transformer primary voltage.

Theoretical analysis of ARC constriction

Description: The physics of the thermionic converter is governed by strong electrode-plasma interactions (emissions surface scattering, charge exchange) and weak interactions (diffusion, radiation) at the maximum interelectrode plasma radius. The physical processes are thus mostly convective in thin sheaths in front of the electrodes and mostly diffusive and radiative in the plasma bulk. The physical boundaries are open boundaries to particle transfer (electrons emitted or absorbed by the electrodes, all pa… more

Working with the states to transport TMI-2 core debris

Description: Close communications with state officials has been a key factor in success of the Three Mile Island Unit 2 core debris shipments. The US Department of Energy made extensive efforts to provide state officials with schedule information, answer technical questions, and satisfy concerns. Communications started before the campaign and continued during shipments and at intervals between shipments. Those efforts led to good working relationships with the states, kept governors and other state official… more

Feasibility of using hydrothermal resources in Malaysian prawn aquaculture. Final report

Description: The potential application of geothermal resources in South Carolina for freshwater prawn aquaculture was examined. In coastal S.C. 23 existing geothermal well sites were identified which encompassed an area which ranged from Georgetown to Beaufort. Depth averaged approx. 615 m while temperature averaged approx. 37/sup 0/C. Artesian flow rates varied from 190 to 2650 1/min. Detailed water quality analyses were conducted at 12 sites. In general, major differences from surface waters were in chlor… more

Fiber optic temperature sensor using a Y{sub 2}O{sub 2}S:Eu thermographic phosphor

Description: This report details the development and testing of a thermographic-phosphor-based fiber-optic temperature sensor. The sensor is constructed by removing a region of the fiber jacket and cladding, then coating the exposed core with yttrium oxysulfide doped with a europium activator (Y{sub 2}O{sub 2}S:Eu). When photoexcited, the europium in the host lattice emits a sharp-line fluorescence spectrum that is characteristic of the temperature of the host crystal lattice. By measuring fluorescence life… more
