Absolute calibration in vivo measurement systems

Description: Lawrence Livermore National Laboratory (LLNL) is currently investigating a new method for obtaining absolute calibration factors for radiation measurement systems used to measure internally deposited radionuclides in vivo. Absolute calibration of in vivo measurement systems will eliminate the need to generate a series of human surrogate structures (i.e., phantoms) for calibrating in vivo measurement systems. The absolute calibration of in vivo measurement systems utilizes magnetic resonance ima… more

Acid measurements via near-infrared spectroscopy

Description: We were able to predict acid concentration to {plus_minus}0.08M HNO{sub 3}. In the presence of Al{sup 3} interference, the prediction dropped to {plus_minus}0.29 mols/liter over the range 0 to 9M HNO{sub 3}. Temperature affects the prediction of acid adversely and would have to be modelled out or the sample cell thermostated prior to using this method. 10 refs, 12 figs.(DLC)

Acrylic mechanical bond tests

Description: The tensile strength of bonded acrylic is tested as a function of bond joint thickness. 0.125 in. thick bond joints were found to posses the maximum strength while the acceptable range of joints varied from 0.063 in. to almost 0.25 in. Such joints are used in the Sudbury Neutrino Observatory.

Assessment of impacts at the advanced test reactor as a result of chemical releases at the Idaho Chemical Processing Plant

Description: This report provides an assessment of potential impacts at the Advanced Test Reactor Facility (ATR) resulting from accidental chemical spill at the Idaho Chemical Processing Plant (ICPP). Spills postulated to occur at the Lincoln Blvd turnoff to ICPP were also evaluated. Peak and time weighted average concentrations were calculated for receptors at the ATR facility and the Test Reactor Area guard station at a height above ground level of 1.0 m. Calculated concentrations were then compared to th… more

An Asymmetric B Factory Based on PEP

Description: In this report we describe a design for a high-luminosity Asymmetric B Factory to be built in the PEP tunnel on the SLAC site. This proposal, a collaborative effort SLAC, LBL, and LLNL, is the culmination of more than two years of effort aimed at the design and construction of an asymmetric e{sup +}e{sup {minus}} collider capable of achieving a luminosity of L = 3 {times} 10{sup 33} cm{sup {minus}2} s{sup {minus}1}. The configuration adopted utilizes two storage rings, and electron ring operati… more

Beam to Shell Temperature Differencees for the CC Cryostat

Description: This note documents the calculation of stresses resulting from temperature differences between the CC cryostat shell and the module array support beams, and the calculation of corresponding maximum allowable temperature differences to be monitored during the cooldown of the cryostat. A finite element model of a portion of the inner vessel shell was analyzed for a uniform temperature change. The shell was assumed to be completely restrained by the support beams. A maximum allowable temperature d… more

Bevalac operations update

Description: The Bevalac passed the recent Tiger Team assessment with flying colors, thanks to the unremitting effort of countless people over the last several months, pulling miles of cables, sending tons of valuable'' junk to salvage, painting, pushing brooms, writing operating procedures. It is time to look ahead now and plan for doing science again; however, it is not business as usual. The Bevalac survived, but not without changes. There are more procedures to be followed, safety appraisals to be made,… more

Biotechnology and Genetic Optimization of Fast-Growing Hardwoods

Description: A biotechnology research program was initiated to develop new clones of fast-growing Populus clones resistant to the herbicide glyphosate and resistant to the leaf-spot and canker disease caused by the fungus Septoria musiva. Glyphosate-resistant callus was selected from stem segments cultured in vitro on media supplemented with the herbicide. Plants were regenerated from the glyphosate-resistant callus tissue. A portion of plants reverted to a glyphosate susceptible phenotype during organogene… more

Bond Strength of Cementitious Borehole Plugs in Welded Tuff

Description: Axial loads on plugs or seals in an underground repository due to gas, water pressures and temperature changes induced subsequent to waste and plug emplacement lead to shear stresses at the plug/rock contact. Therefore, the bond between the plug and rock is a critical element for the design and effectiveness of plugs in boreholes, shafts or tunnels. This study includes a systematic investigation of the bond strength of cementitious borehole plugs in welded tuff. Analytical and numerical analysi… more

Can non-Gaussian fluctuations for structure formation arise from inflation

Description: Non-Guassian fluctuation for structure formation may be generated during the inflationary epoch from the nonlinear interaction of two scalar fields with gravity. Semi-analytical calculations are given describing nonlinear long wavelength evolution in 3 + 1 dimensions. Long wavelength fields are governed by a single equation, the separated Hamilton-Jacobi equation (SHJE). I discuss complete analytic solutions of the SHJE for two scalar fields with a potential whose logarithm 1n V ({phi}{sub j}) … more

(Centralized reliability data organization for liquid metal reactor components)

Description: The Centralized Reliability Data Organization is a data bank and data analysis center, focusing on reliability, availability, and maintainability (RAM) data for components (e.g., valves, pumps, etc.) operating in liquid metal reactors and test facilities. PNC staff are using the CREDO data base as a resource for their development of a probabilistic safety assessment (PSA) for the MONJU fast breeder reactor now under construction. The meeting was held to discuss: (a) progress in FY 1989, (b) res… more

Changing by Degrees: Steps To Reduce Greenhouse Gases

Description: This report discusses the actions necessary to effect a major reduction of United States. carbon dioxide emissions. The U.S. is the world’s leading industrial society and largest single emitter of carbon dioxide. Climate change therefore presents a unique challenge to this Nation. It is a threat that will require major prudent political actions even before all the scientific certainties are resolved. The analysis, prevention, and remediation of global warming will require unprecedented internat… more

Characterization of the WRI entrained-flow reactor

Description: The ultimate goal of the current research has been to obtain kinetic and stoichiometric data on the high-heating-rate pyrolysis of a western oil shale. To accomplish this, a reactor system had to be chosen that could attain the high heating rates observed in fluid beds, but avoid some of their limitations. one of the most favorable high-heating-rate systems for accurate reaction research is an entrained-flow reactor. With proper design, heating rates can equal and surpass those observed in flui… more

Chemical and physical processes in Tank 241-SY-101: A preliminary report

Description: Since 1942, chemical and radioactive waste have been stored in underground tanks at the Hanford Site. In March 1981 one of the double shell tanks, 241-SY-101 (called 101-SY), began venting large quantities of gas, primarily hydrogen and nitrous oxide. Because of the potential for explosion Westinghouse Hanford Company and the US Department of Energy realized the need for knowledge about the processes occurring in this tank that lead to generation of the gases. In June 1990, the Pacific Northwes… more
