Potential of pyroprocessing for partitioning purex wastes (open access)

Potential of pyroprocessing for partitioning purex wastes

The processes are extremely compact. The process reagents are highly resistant to radiation damage and, therefore, can be used to handle short-cooled, highly concentrated waste with negligible degradation. Most reagents can be recycled back through the process many times, thereby minimizing the generation of waste products, and also reducing the process cost. Fission-product wastes are discharged from the process as concentrated, solid wastes, typically in a metal matrix suitable for permanent disposal. Long cooling periods are not needed prior to conversion to a suitable waste form. The recovered actinides are obtained as metals and cen be easily stored or shipped. Pyrochemical processing of nuclear fuels should be considered as a second generation technology.

Liquid fuels production from biomass. Progress report No. 8, April 1-June 30, 1979 (open access)

Liquid fuels production from biomass. Progress report No. 8, April 1-June 30, 1979

The current program to convert biomass into liquid hydrocarbon fuels is an extension of the previous program to ferment marine algae to acetic acid. In that study, it was found that marine algae could be converted to higher aliphatic organic acids and that these acids could be readily removed from the fermentation both by membrane or liquid-liquid extraction. It was then proposed to convert these higher organic acids to aliphatic hydrocarbons via Kolbe Electrolysis, which may be used as a diesel fuel. The accompishments in this program for the first year of work are as follows: a coenzyme M anologue, 2-bromoethanesulfonic acid has been shown to be an effective suppressor of methane in nonsterile anaerobic fermentation of cellulosic substrates; a tapered auger device has been designed and built which has been demonstrated on the bench to be effective for adding substrate and removing residue in a continuous manner from a fixed packed bed fermenter; a solvent extracter system using kerosene as the nonaqueous phase has been constructed and is currently in operation in series with the 300 liter fixed packed bed fermenter; although additional work is required to optimize the electrolysis process the electrolytic oxidation of organic acids produced in …

Dispersive effects of transverse displacements of SLC Arc magnets (open access)

Dispersive effects of transverse displacements of SLC Arc magnets

The SLC Arc magnets are subject to random displacements and field errors resulting in unpredictable transverse displacement of the central trajectory from that of the design. The chosen method of correcting this perturbed trajectory in the SLC Arcs utilizes mechanical movement of the combined function magnets which compose the Arc transport lines. Here we present the results of a recent investigation substantiating the earlier results which led to the adoption of this method.

Fiber-tile optical studies at Argonne (open access)

Fiber-tile optical studies at Argonne

In support of a fiber-tile calorimeter for SDC, we have done studies on a number of topics. The most basic problems were light output and uniformity of response. Using a small electron beam, we have studied fiber placement, tile preparation, wrapping and masking, fiber splicing, fiber routing, phototube response, and some degradation factors. We found two configurations which produced more light output than the others and reasonably uniform response. We have chosen one of these to go into production for the EM test module on the basis of fiber routing for ease of assembly of the calorimeter. We have also applied some of the tools we developed to CDF end plug tile uniformity, shower max testing and development for a couple of detectors, and development of better techniques for radiation damage studies. 18 figs.

Securities And Exchange Commission: Review of Fiscal Year 2003 and 2004 Budget Allocations

A letter report issued by the Government Accountability Office with an abstract that begins "This report responds to a statement in the Conference Report on the Securities and Exchange Commission's (SEC) fiscal year 2004 appropriations directing GAO to study SEC's allocation of its increased funding for fiscal years 2003 and 2004. Historically, SEC has faced high staff turnover rates, long stretches of unfilled staff positions, and growing resource needs. Additionally, the agency has faced significant needs in its information technology area. In response to these trends and several high-profile corporate failures and financial scandals, Congress approved significant increases in SEC's appropriations to help improve oversight and increase public confidence in financial markets. This report builds on several reports GAO has issued on these issues. GAO was asked to review SEC's (1) allocation of its fiscal year 2003 and 2004 funds and (2) use of its information technology funding in fiscal year 2003 and its plan for 2004."

A letter report issued by the Government Accountability Office with an abstract that begins "As part of international efforts to ensure maritime safety and security--and to carry out its mandates under the Maritime Transportation Security Act of 2002--the U.S. Coast Guard is developing an automatic identification system (AIS) that should enable it to monitor ships traveling to and through U.S. waters. For AIS to operate nationwide, ships need equipment to transmit and receive AIS signals, and the Coast Guard needs shore stations and designated radio frequencies to keep track of the ships' identities and movements. Yet unresolved frequency issues between the Coast Guard and a private company, MariTEL, have come before the Federal Communications Commission (FCC). GAO reviewed federal agencies' progress in developing AIS nationwide and identified certain challenges and opportunities in completing the work."

World Health Organization: Reform Agenda Developed, but U.S. Actions to Monitor Progress Could be Enhanced

A letter report issued by the Government Accountability Office with an abstract that begins "In May 2012, 194 member states approved components of the World Health Organization's (WHO) reform agenda, encompassing three broad areas--priority-setting, governance, and management reforms--that generally address the challenges identified by stakeholders. According to WHO officials, member state representatives, and other stakeholders, some of the challenges facing WHO include its (1) lack of clear organizational priorities; (2) lack of predictable and flexible financing; and (3) highly decentralized organizational structure. In developing its reform agenda, WHO consulted with member states, employees, and other parties to gather their views and feedback. In addition, WHO has commissioned three ongoing evaluations to provide input into the reform process. The first stage of one of the planned evaluations was conducted by WHO's External Auditor, which concluded in March 2012 that WHO's reform proposals are comprehensive in addressing challenges faced by the organization. WHO continues to consult with member states on priority-setting and governance proposals, which generally require extensive deliberation and consensus from member states. In November 2011, the WHO Executive Board approved WHO's management reform proposals in several areas, and requested further development of proposals in other areas. In May 2012, WHO …
