Development of ultrafiltration and inorganic adsorbents for reducing volumes of low-level and intermediate-level liquid waste: January--March 1978
The exposure of noncellulosic ultrafiltration membranes to a radioactive environment simulating up to 24 months of exposure to a beta dose of 10 ..mu..Ci/cm/sup 3/ and a gamma dose of 10/sup -5/ ..mu..Ci/cm/sup 3/ did not show any conclusive evidence of membrane degradation. Viscosity measurements for control membranes and irradiated membranes indicate no changes in polymer molecular weight were caused by the radiation exposure. This, in turn, suggests no physical or mechanical degradation took place. A continuous run on the ultrafiltration pilot plant was completed. The run lasted 33.5 hr; during this period, the flux declined from 4 gal/min to 0.8 gal/min while rejection of alpha activity increased slightly. A total of 20,000 gal were processed through the ultrafiltration system. The small laboratory column tests were continued with uranium-233 and americium-241. Several new resins were being evaluated along with the same type of resin as used before with uranium-233 and plutonium-238. Tests were continued with the 2-in. Engineering Columns using ultrafiltration product spiked with uranium-233.

Nuclear Analysis of Various Spert-III Critical Experiments
Editor please delete 26456.<><DSN>16:026457<ABS>Work done in the P122 reactor control actuator area is summarized. Actuators were required to radially position the absorber blades in the core of the reactor. The P122C1 was a subsonic power plant and temperatures were low enough to permit the use of hydraulics in the actuator area. The program was reoriented and the power plant designated P122C3 which was a supersonic version of the folded flow power plant. The ambient temperature at maximum power was high enough to require pneumatic actuation of the control blades. The program was reoriented after two design iterations of the subsonic power plant. A test model of the actuating equipment and the entire linkage assembly was on hand and completed when the program was cancelled. The linkage was being redesigned for the supersonic application and special bearings were ordered for fabrication into the lower temperature rig. The actual mechanical concepts of the pneumatic actuator were under study when the program was cancelled. (auth)

Fundamental mechanisms in flue gas conditioning
This project is divided into four tasks. The Management Plan was developed in task 1. Task 2, Evaluation of Mechanisms in FGD Sorbent and Ash Interactions, focuses on the characteristics of binary mixtures of these distinct powders. Task 3, Evaluation of Mechanisms in Conditioning Agents and Ash, is designed to examine the effects of various conditioning agents on fine ash particles to determine the mechanisms by which these agents alter the physical properties of the ash. Tasks 2 and 3 began with an extensive literature search and the assembly of existing theories. This phase of the project is now complete. During the past quarter, initial preparations of laboratory equipment for laboratory testing have been made. A plan for initial laboratory tests has been submitted to the Project Manager for review. Laboratory testing will commence once these laboratory plans have been formally approved. The results of the work performed under task 2 and 3 will be included in a Flue Gas Conditioning Model that will be issued under task 4. The Final Report for the project will also be prepared under task 4.

Applications of Micellar Enzymology to Clean Coal Technology. [Laccase]
This project is designed to develop methods for pre-combustion coal remediation by implementing recent advances in enzyme biochemistry. The novel approach of this study is incorporation of hydrophilic oxidative enzymes in reverse micelles in an organic solvent. Enzymes from commercial sources or microbial extracts are being investigated for their capacity to remove organic sulfur from coal by oxidation of the sulfur groups, splitting of C-S bonds and loss of sulfur as sulfuric acid. Dibenzothiophene (DBT) and ethylphenylsulfide (EPS) are serving as models of organic sulfur-containing components of coal in initial studies.

Veterans Benefits Administration: Progress Made in Long-Term Effort to Replace Benefits Payment System, but Challenges Persist
A letter report issued by the Government Accountability Office with an abstract that begins "Since 1996, the Veterans Benefit Administration (VBA) has been working on an initiative to replace its aging system for paying compensation and pension benefits. In 2005, concerned about the slow pace of development, VBA contracted with the Software Engineering Institute (SEI) for an independent evaluation of the project, known as the Veterans Service Network (VETSNET). SEI advised VBA to continue working on the project at a reduced pace while addressing management and organization weaknesses that it determined had hampered the project's progress. GAO was requested to determine to what extent the VETSNET project has followed the course of action recommended by SEI and describe the project's current status. To perform its review, GAO analyzed project documentation, conducted site visits, and interviewed key program officials."

Internal Revenue Service: Assessment of the Interim Results of the 2006 Filing Season and Fiscal Year 2007 Budget Request
Testimony issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) filing season performance affects tens of millions of taxpayers who expect timely refunds and accurate answers to their tax questions. IRS's budget request is a planning tool showing how it intends to provide taxpayer service and enforce the tax laws in 2007. It is also the first in a series of annual steps that will determine whether IRS meets its new long-term goals of increasing tax compliance and reducing taxpayers' acceptance of cheating on their taxes. Tax law enforcement remains on GAO's list of high-risk federal programs, in part, because of the persistence of a large tax gap. IRS recently estimated the gross tax gap, the difference between what taxpayers owe and what they voluntarily pay, to be $345 billion for 2001. GAO assessed (1) IRS's interim 2006 filing season performance; (2) the budget request; and (3) how the budget helps IRS achieve its longterm goals. GAO compared performance and the requested budget to previous years."

Troubled Asset Relief Program: Update of Government Assistance Provided to AIG
A letter report issued by the Government Accountability Office with an abstract that begins "Assistance provided by the Department of the Treasury (Treasury) under the Troubled Asset Relief Program (TARP) and the Board of Governors of the Federal Reserve System (Federal Reserve) to American International Group, Inc. (AIG)--a holding company that, through its subsidiaries, is engaged in a broad range of insurance and insurance-related activities in the United States and abroad--represents one of the federal government's largest investments in a private sector institution since the financial crisis began in 2008. Treasury and the Federal Reserve provided assistance to AIG in September 2008 that was restructured in November 2008 and March 2009. As part of GAO's statutorily mandated oversight of TARP, this report updates the risk and repayment indicators GAO originally reported in September 2009 (GAO-09-975). Specifically in this report, GAO discusses (1) trends in AIG's financial condition, (2) trends in the unwinding of AIG Financial Products (AIGFP), (3) the financial condition of AIG's insurance companies, and (4) the status of AIG's repayment of its federal assistance.

Forest Service: Better Data and Clear Priorities Are Needed to Address Increasing Reforestation and Timber Stand Improvement Needs
Testimony issued by the Government Accountability Office with an abstract that begins "In 2004, the Forest Service reported to the Congress that it had a backlog of nearly 900,000 acres of land needing reforestation--the planting and natural regeneration of trees. Reforestation and subsequent timber stand improvement treatments, such as thinning trees and removing competing vegetation, are critical to restoring and improving the health of our national forests after timber harvests or natural disturbances such as wildland fires. GAO was asked to (1) examine the reported trends in federal lands needing reforestation and timber stand improvement, (2) identify the factors that have contributed to these trends, and (3) describe any potential effects of these trends that Forest Service officials have identified. This testimony is based on GAO's report Forest Service: Better Data Are Needed to Identify and Prioritize Reforestation and Timber Stand Improvement Needs (GAO-05-374), being released today."

Gas Pipeline Safety: Preliminary Observations on the Implementation of the Integrity Management Program
Testimony issued by the Government Accountability Office with an abstract that begins "About a dozen people are killed or injured in natural gas transmission pipeline incidents each year. In an effort to improve upon this safety record, the Pipeline Safety Improvement Act of 2002 requires that operators assess pipeline segments in about 20,000 miles of highly populated or frequented areas for safety risks, such as corrosion, welding defects, or incorrect operation. Half of these baseline assessments must be done by December 2007, and the remainder by December 2012. Operators must then repair or replace any defective pipelines, and reassess these pipeline segments for corrosion damage at least every 7 years. The Pipeline and Hazardous Materials Safety Administration (PHMSA) administers this program, called gas integrity management. This testimony is based on ongoing work for this Subcommittee and for other committees, as required by the 2002 act. The testimony provides preliminary results on the safety effects of (1) PHMSA's gas integrity management program and (2) the requirement that operators reassess their natural gas pipelines at least every 7 years. It also discusses how PHMSA has acted to strengthen its enforcement program in response to recommendations GAO made in 2004. GAO expects to …

Environmental Satellites: Strategy Needed to Sustain Critical Climate and Space Weather Measurements
A letter report issued by the Government Accountability Office with an abstract that begins "Environmental satellites provide data on the earth and its space environment that are used for forecasting the weather, measuring variations in climate over time, and predicting space weather. In planning for the next generation of these satellites, federal agencies originally sought to fulfill weather, climate, and space weather requirements. However, in 2006, federal agencies restructured two key satellite acquisitions, the National Polar-orbiting Operational Environmental Satellite System (NPOESS) and the Geostationary Operational Environmental Satellite-R series (GOES-R). This involved removing key climate and space weather instruments. GAO was asked to (1) assess plans for restoring the capabilities that were removed from the two key satellite acquisitions, (2) evaluate federal efforts to establish a strategy for the long-term provision of satellite-provided climate data, and (3) evaluate federal efforts to establish a strategy for the longterm provision of satellite-provided space weather data. To do so, GAO analyzed agency plans and reports."

Defense Inventory: Opportunities Exist to Save Billions by Reducing Air Force's Unneeded Spare Parts Inventory
A letter report issued by the Government Accountability Office with an abstract that begins "At a time when U.S. military forces and their equipment are in high demand, effective management of the Department of Defense's (DOD) inventory is critical to ensure that the warfighter has the right items at the right time. The Air Force is the largest contributor to DOD's total on-hand inventory on the basis of inventory value. Under the statutory authority of the Comptroller General to conduct evaluations on his own initiative, GAO determined the extent to which (1) the Air Force's on-order and on-hand inventory reflect the amount of inventory needed to support required inventory levels from fiscal years 2002 through 2005, and (2) the Air Force had shortages in its inventory needed to support required levels during this period. To address these objectives GAO analyzed Air Force secondary inventory data (spare parts such as engines and guided missiles) from fiscal years 2002 through 2005."

Polar-Orbiting Operational Environmental Satellites: Restructuring Is Under Way, but Technical Challenges and Risks Remain
A letter report issued by the Government Accountability Office with an abstract that begins "The National Polar-orbiting Operational Environmental Satellite System (NPOESS) is a tri-agency acquisition--managed by the Departments of Commerce and Defense and the National Aeronautics and Space Administration--which experienced escalating costs, schedule delays, and technical difficulties. These factors led to a June 2006 decision to restructure the program thereby decreasing the program's complexity, increasing its estimated cost to $12.5 billion, and delaying the first two satellites by 3 to 5 years. GAO was asked to (1) assess progress in restructuring the acquisition, (2) evaluate progress in establishing an effective management structure, (3) assess the reliability of the cost and schedule estimate, and (4) identify the status and key risks facing the program's major segments. To do so, GAO analyzed program and contractor data, attended program reviews, and interviewed program officials"
