Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed its recent reports concerning the export controls for high performance computers, focusing on how the executive branch: (1) assesses the national security risks associated with the export of high performance computers going to countries of concern; and (2) determines when the exports of computers at existing performance levels can no longer be controlled."

Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed the data that the Environmental Protection Agency (EPA) and the states have for making critical water quality decisions required by the Clean Water Act, focusing on: (1) the adequacy of the data for identifying waters for states' 303(d) lists; (2) the adequacy of data for developing total maximum daily loads (TMDL) for those waters; and (3) key factors that affect the states' abilities to develop TMDLs."

Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed the substantial gainful activity (SGA) level established for blind beneficiaries of Social Security Disability Insurance (DI), focusing on the: (1) differences in employment circumstances affecting people with blindness compared with those affecting people with other disabilities; and (2) potential impact of changes in SGA levels on the DI program and on the Social Security trust funds."

Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed the effectiveness of the Health Resources and Services Administration's (HRSA) two safety-net programs--the Community and Migrant Health Center program and the National Health Service Corps--to improve access to medically underserved populations."

This is a summary of the results of my calculations compared to Elisabeth Wolfrum's data on the Vulcan imprint experiments. The material strength makes essentially no difference to the growth of perturbations seeded by the laser imprint. For the low-intensity case (30 J laser energy, beam intensity of 0.5 x 10{sup 12} W/cm{sup 2}) the thin (2 microns) Al foil melts quickly from the front (driven) surface and decompresses quickly from the back surface, so there is actually only a fraction of the foil that is solid and compressed, and then for only a short time. And this solid fraction is not accelerating much during this short time. In particular, the shock (which is at about 250 kbar when it is about half way through the foil) travels entirely through the foil in about 0.25 ns. At 0.3 ns the ablation front is 0.6 {micro}m in from the original position of the front surface, the next 0.6 {micro}m is melted, so only the back 0.8 {micro}m is solid and compressed. This solid portion, though, is not moving much; the place where the imprinted perturbations are growing is back at the ablation front, where the perturbations are clearly growing fluid-like. By …

Fueled clads for radioisotope power systems are produced by encapsulating {sup 238}PuO{sub 2} in iridium alloy cups, which are joined at their equators by gas tungsten arc welding. Cracking problems at the girth weld tie-in area during production of the Galileo/Ulysses GPHS capsules led to the development of a first-generation ultrasonic test for girth weld inspection at the Savannah River Plant. A second-generation test and equipment with significantly improved sensitivity and accuracy were jointly developed by the Oak Ridge Y-12 Plant and Westinghouse Savannah River Company for use during the production of Cassini GPHS capsules by the Los Alamos National Laboratory. The test consisted of Lamb wave ultrasonic scanning of the entire girth weld from each end of the capsule combined with a time-of-flight evaluation to aid in characterizing nonrelevant indications. Tangential radiography was also used as a supplementary test for further evaluation of reflector geometry. Each of the 317 fueled GPHS capsules, which were girth welded for the Cassini Program, was subjected to a series of nondestructive tests that included visual, dimensional, helium leak rate, and ultrasonic testing. Thirty-three capsules were rejected prior to ultrasonic testing. Of the 44 capsules rejected by the standard ultrasonic test, 22 were upgraded …

This report interprets information about the tank answering a series of six questions covering areas such as information drivers, tank history, tank comparisons, disposal implications, data quality and quantity, and unique aspects of the tank.

This document identifies the means to determine NPSHa for Hanford waste tanks. It presents the values of vapor pressure and density of Hanford double-shell tank waste as they relate to temperature.

A approach for quantifying meteorological uncertainty is via development of an ensemble of forecasts from slightly perturbed initial conditions (Sivillo et al., 1997) to predict the time evolution of the probability density function of atmospheric variables (Mullen and Baurnhefner, 1994). We create an ensemble of forecasts by varying the initial (and boundary) conditions for the COAMPS meteorological model. The variations in the initial conditions must be consistent with analysis error. Optimally, the range of initial conditions would encompass the ''true'' atmospheric state, but which is never actually known. Our method for creating varying initial conditions is to use different global data sets to derive the necessary data. We use two models from the National Weather Service (the AVN and ETA models) and one from the Navy (the NOGAPS model). In addition to those data sets we perturb the data from those models, using a normally distributed random number at each grid point in the COAMPS model. We perturb the (u,v) wind components, the temperature and the moisture. The size of the perturbation is determined by the variability within that variable field. The forecasts are run for 48 hours. We then use the output from the COAMPS model to drive a …

Geophysical methods have been used for characterization of hydrogeologic conditions and/or contaminant distributions at the Hanford site since at least the mid- to late-1940s. A review of these geophysical methods is presented in two parts: 1) shallow surface-based geophysical methods and 2) borehole geophysical-logging methods.
