Development of improved TRISO-P fuel particle P-PyC coating

Description: Low defect fuels are required for the MHTGR to meet tighter fuel performance for this reactor design (Ref. 1). Exposed heavy metal (HM) contamination levels must be reduced to {le} 1E-5 fraction. Particle coating breakage during the fuel compact fabrication process has been shown to be a major source of HM contamination in the final fuel compacts. Excessive forces are experienced by the coated fuel particles during matrix injection, which leads to coating failure. Adding a sacrificial, low Youn… more

Advanced three-dimensional thermal modeling of a baseline spent fuel repository

Description: A three-dimensional thermal analysis using finite difference techniques was performed to determine the near-field response of a baseline spent fuel repository in a deep geologic salt medium. A baseline design incorporates previous thermal modeling experience and OWI recommendations for areal thermal loading in specifying the waste form properties, package details, and emplacement configuration. The base case in this thermal analysis considers one 10-year old PWR spent fuel assembly emplaced to … more

Exact matched-beam envelopes for undepressed transport in a quadrupole lattice with unequal drift lengths and arbitrary field strength

Description: In 1958, Courant and Snyder analyzed the problem of alternating-gradient beam transport and treated a model without focusing gaps or space charge. Recently we revisited their work and found the exactsolution for matched-beam envelopes in a linear quadrupole lattice [O.A. Anderson and L.L. LoDestro, Phys. Rev. ST Accel. Beams, 2009]. We extend that work here to include the effect of gaps. We derive the exact envelopes and show results for various field strengths, occupancies eta,and gap-length r… more

Particle Distribution From a Unit Source - Part A

Description: Thus we see that the derivation of elementary age theory is based on replacing the probability of collision governed by the Milne kernel by a Gaussian probability having the same zeroth and second moments. It is apparent that the age theory distribution will fail close to the source and at many free paths from the source.

Overview of the geothermal energy development program at the Lawrence Livermore Laboratory

Description: The program consists generally of development of advanced conversion systems, with strong emphasis on a systems approach to find solutions of the problems of scale formation, corrosion/erosion of materials, spent brine disposal and solids handling, and development of reliable, efficient energy conversion systems with strong emphasis on development of the total flow concept. The status of the various parts of this program is reviewed briefly. (MHR)

Does Price Transparency Improve Market Efficiency? Implications of Empirical Evidence in Other Markets for the Health Sector

Description: This report reviews the empirical studies of the effect of changes in price transparency on prices and quality of goods in a variety of industries; addresses the extent to which this evidence might be applicable to the health care market and certain special characteristics of the health care market which may reduce the importance of prices as signals; examines how prices are actually set by hospitals and the evidence that exists on price dispersion both across hospitals and across patient categ… more

Productivity and Injectivity of Horizontal Wells

Description: A general wellbore flow model is presented to incorporate not only frictional, accelerational and gravitational pressure drops, but also the pressure drop caused by inflow. Influence of inflow or outflow on the wellbore pressure drop is analyzed. New friction factor correlations accounting for both inflow and outflow are also developed. The greatest source of uncertainty is reservoir description and how it is used in simulators. Integration of data through geostatistical techniques leads to mul… more

Production Test IP-550-I, Supplement A routine monitoring for moderator oxidation rates

Description: The objective of this supplement to Production Test IP-550-I is to include the K reactors in the program for routinely monitoring graphite oxidation rates. This supplement does not initiate a new program; it continues one which has been in existence for some time. Oxidation of the reactor graphite weakens its structural capacity. At some degree of oxidation, sufficient loss of strength will occur to significantly affect the ability to maintain and operate the reactors. For this reason it is nec… more

PRODUCTION IMPROVEMENT FROM INCREASED PERMEABILITY USING ENGINEERED BIOCHEMICAL SECONDARY RECOVERY METHODOLOGY IN MARGINAL WELLS OF THE EAST TEXAS FIELD

Description: A combination of a regenerating biochemical mixture and an organic surfactant has been applied to wells in the East Texas Field with the goal of restoring permeability, reversing formation damage, mobilizing hydrocarbons, and ultimately increasing production. Initial work in task 1 was designed to open the perforations and remove blockages of scale, asphaltene, and other corrosion debris. This was accomplished on three wells that produce from the Woodbine, and was necessary to prepare the wells… more

Metal-Organic Frameworks: Literature Survey and Recommendation of Potential Sorbent Materials

Description: Metal-organic frameworks (MOFs) are a special type of porous material with a number of unique properties, including exceptionally high surface areas, large internal pore volumes (void space) and tunable pore sizes. These materials are prepared through the assembly of molecular building blocks into ordered three-dimensional structures. The bulk properties of the MOF are determined by the nature of the building blocks and, as such, these materials can be designed with special characteristics that… more
