D0 Silicon Upgrade: Thermally Induced Stresses in the Components of a D0 Ladder in the Silicon Tracker

Description: During the operation of the silicon tracker, the ladders will be in direct thermal contact with a cooling channel. The expected operating temperature of the cooling channel is 0 C, maintained by a cooling fluid whose bulk temperature is below 0 C. The assembly temperature is assumed to be 22 C. Due to the mis-match of material expansion coefficients, thermal stresses will be induced in the epoxy, beryllium, and silicon of the ladders. Calculations are presented here as well as some thermal cycl… more

Description: The Next Generation Geothermal Power Plants (NGGPP) study provides the firm estimates - in the public domain - of the cost and performance of U.S. geothermal systems and their main components in the early 1990s. The study was funded by the U.S. Department of Energy Geothermal Research Program, managed for DOE by Evan Hughes of the Electric Power Research Institute, Palo Alto, CA, and conducted by John Brugman and others of the CE Holt Consulting Firm, Pasadena, CA. The printed NGGPP reports con… more

Hydrologic Properties of Aquifers in the Central Savannah River Area

Description: The hydrologic properties of selected aquifer systems underlying the Milhaven and Girard sites in Georgia were determined through a series of aquifer performance tests performed from October, 1994 to January, 1995. At the Milhaven site, the systems under investigation consisted of the upper, middle and lower components of the Upper Floridan, the lower Dublin, and the lower Midville aquifers. At the Dublin site, only the lower Dublin and lower Midville aquifers were tested. In addition, the hydr… more

The Line Item Veto Act: Procedural Issues

Description: At various times, Congress has given the President statutory authority not to spend appropriated funds. That authority was elaborated and made more systematic with the Impoundment Control Act of 1974, which permitted the President to delay the expenditure of funds (deferral authority) and to cancel funds (rescission authority). To rescind funds, the President needed the support of both houses within 45 days.

Industrial Competitiveness and Technological Advancement: Debate Over Government Policy

Description: Concern has been growing that the pace of U.S. technological advancement is declining, with negative consequences for U.S. economic growth, productivity, and international competitiveness. Because technology can contribute to economic growth and productivity increases, congressional interest has focused on how to augment private sector technological development. Legislative activity over the past decade has created a policy for technology development, albeit an ad hoc one. Because of the lack o… more

Cooperative R&D: Federal Efforts to Promote Industrial Competitiveness

Description: In response to the foreign challenge in the global marketplace, the United States Congress has explored ways to stimulate technological advancement in the private sector. The government has supported various efforts to promote cooperative research and development activities among industry, universities, and the federal R&D establishment designed to increase the competitiveness of American industry and to encourage the generation of new products, processes, and services. Among the issues before … more

Clean Air Act Issues

Description: The 104th Congress enacted four bills modifying provisions of the Clean Air Act (CAA) and held numerous oversight hearings, as EPA and the states continued to implement requirements of the Act's 1990 Amendments. The Amendments set deadlines for issuance of new regulations and attainment of air quality standards.

Double-shell tank remaining useful life estimates

Description: The existing 28 double-shell tanks (DSTS) at Hanford are currently planned to continue operation through the year 2028 when disposal schedules show removal of waste. This schedule will place the DSTs in a service life window of 4O to 60 years depending on tank construction date and actual retirement date. This paper examines corrosion- related life-limiting conditions of DSTs and reports the results of remaining useful life models developed for estimating remaining tank life. Three models based… more

Development of precipitated iron Fischer-Tropsch catalysts. Quarterly technical progress report, 1 April 1996--30 June 1996

Description: The overall contract objectives are to: (1) demonstrate repeatability of performance and preparation procedure of two high activity, high alpha iron Fischer-Tropsch catalysts synthesized at Texas A&M University (TAMU) during the DOE Contract DE-AC22-89PC89868; (2) seek potential improvements in the catalyst performance through variations in process conditions, pretreatment procedures and/or modifications in catalyst synthesis; (3) investigate performance of catalysts in a small scale bubble col… more

Test plan for evaluation of primary exhaust ventilation flow meters for double shell hydrogen watch list tanks

Description: This document is a plan for testing four different flow meters for use in the primary exhaust ventilation ducts of Double Shell Tanks on the hydrogen watch list that do not already have this capability. This currently includes tanks 241-AW-101, 241-AN-103, 241-AN-104, 241-AN-105, and 241-SY-103. The anticipated airflow velocity in these tanks range from 0.25 m/s(50 ft/min) to 1.78 m/s (350 ft/min). Past experiences at Hanford are forcing the evaluation and selection of instruments to be used at… more

Slurry phase iron catalysts for indirect coal liquefaction. Second semi-annual progress report, January 5, 1996--July 4, 1996

Description: During this period, work was continued on understanding the attrition of precipitated iron catalysts and work initiated on synthesizing catalysts containing silica binders. Use of a sedigraph particle size analyzer with an ultrasonic probe provides a simple method to test the strength of catalyst agglomerates, allowing the strength comparison of silica and hematite catalysts (the former is considerably stronger). Study of Fe/silica interactions was continued. Addition of a colloidal silica prec… more

Development of precipitated iron Fischer-Tropsch catalysts. Quarterly technical progress report for the period July 1, 1996--September 30, 1996

Description: Two slurry reactor tests were completed in continuation of our studies on the effect of pretreatment conditions on catalyst reactivity and selectivity. Exceptionally good performance was obtained in run SA-2186, using the new pretreatment developed at Texas A&M University. The work on catalyst characterization by temperature programmed and isothermal reduction on a variety of iron catalysts, with different amounts of promoters, has been continued. These studies are complementing our work on pre… more

A risk management approach to nuclear waste inventory versus storage capacity

Description: Nuclear waste is presently stored in 177 underground storage tanks at -the U. S. Department of Energy`s Hanford Site in Washington State. The storage tanks are of two construction types, 149 single-shell tanks (SSTS) and 28 double-shell tanks (DSTs). No waste has been added to the SSTs since 1980. However, the DSTs are configured to receive additional waste from site waste generators. The overall waste inventory is time dependent and strongly influenced by present and future tank farm operation… more
