Supporting Analysis for Thermal Suitability of Fuel Elements for SM-1A Core I Loading
A recommended SM-1A Core I loading chart was derived from available, metallurgically acceptable elements at the SM-1A and SM-1 sites. The derivation was based on local thermal and hydraulic considerations of minimum elementto- element coolant channel clearances. These clearances were determined from field inspection measurements of outer fuel plate spacing, as modified by analytical calculations of plate ripple growth during exposure to reactor operating thermal stresses.

RLPORINC: the RELAP4/MOD5 interface to ORINC
The Oak Ridge Inverse code, ORINC, calculates the temperature distribution in an electric core pin from internal temperatures and the conditions in the surrounding environment. While the internal temperatures can be obtained from thermocouples in the Thermal Hydraulic Test Facility, the needed environmental conditions cannot be determined as directly from experimental data. However, this information can be determined from a modified version of the Reactor Linearized Analysis Program, RELAP. In particular, the IBM form of RELAP/MOD5 UPDATE2, as released by the Idaho National Engineering Laboratory, was modified to save the proper information in a convenient format. This document describes this RELAP-to-ORINC interface version of RELAP4 which has been named RLPORINC.

Heavy recycle solvent studies in two-stage coal liquefaction. Final technical report, September 1, 1982-December 30, 1983
The objective of this program has been to study the chemistry of the components with high boiling points in a direct coal liquefaction recycle solvent and to identify those components which lead to higher overall yields and improved product stability in the initial coal dissolution step of direct coal liquefaction processes. The major conclusions are: -454 C recycle solvent is primarily aromatic hydrocarbons (73%) and contains almost no asphaltenes; +454 C recycle solvent is primarily asphaltenes and aromatic hydrocarbons; recycle solvent also contains aliphatic hydrocarbons, N-containing aromatics and O-containing aromatics; heteroatoms in coal derived materials seem to be grouped by type, i.e. acidic O and basic N and sulfur occur together; under helium a small net amount of hydrogen and more CO and CO/sub 2/ are produced than under hydrogen; under hydrogen the amounts of H/sub 2/S and hydrocarbon gases are increased and a small amount of hydrogen gas is usually consumed; overall coal conversions to THF solubles are improved by adding more -454 C solvent but decreased by adding +454 C solvent; for added fractions of -454 C solvent the pecent conversion to THF solubles increases in the order aromatic hydrocarbons (+7.2) > aliphatic hydrocarbons (+0.8) > no added …

Numerical Analysis of Neutron Resonances
Neutron resonances are analyzed numerically by determining the resonant energies, the total widths, and the neutron widths of the resonances. It was assumed that the total cross section can be represented by the sum of single- level Breit-Wigner formulas, with interference between resonance and potential scattering but no interference between resonances; that the Doppler broadening is represented by a Gaussian function; and that the instrument resolution is represented by a Gaussian function. Gauss' method was used to reduce the nonlinear problem to one in which linear methods can be applied. Some unusual techniques were used for evaluating the integrals in the function for calculating the transmission. Two programs for analyzing transmission data to obtain the parameters of the resonances were written for the IBM 7090 computer. The first program is a shape analysis for determining the resonant energies, the total widths, and the neutron widths of the resonances. This program analyzes the transmission data for as many as six resonances at once. The second program is an area analysis for determining the neutron widths of the resonances for assumed total widths. This program analyzes transmission data containing as many as 20 resonances at once. (auth)

Preparation of a computer-compatible data base on an operating total energy system. Final report. [Indian Creek Village, Overland Park, Johnson Co. , Kansas]
This report documents the development of a computerized data base on the long-term performance of the Indian Creek Total Energy System, and it is intended to be a user's manual for the data base and the accompanying energy-balance computer program. The data base may be used as a standard of comparison for the performance predicted by energy-system-simulation software. The TES became operational in 1972 to meet the projected electrical, space conditioning, and domestic hot water needs for the garden-type apartment complex. The dual-fuel engine are provided with both gas and No. 2 oil connections. Heat from the exhaust flues is extracted in the heat recovery units. Following the introductory chapter, Chapter II provides a description and background history on the highly instrumented and efficiently operated Indian Creek Total Energy System. Also included in Chapter II is a discussion of the instrumentation used to monitor the performance of the total energy system. Chapter III provides a detailed description of the data base, including the methodology used to supply missing data. Chapter IV develops the energy balance equations and relates them to the computer program and the data base. Chapter V presents the results of exercising the energy balance computer model driven …

A Bench-Scale Natural-Recirculation Dissolver
A natural-recirculation dissolver closely approaching a stirred-tank reactor in behavior was developed, and its feasibility was demonstrated in the mercury-catalyzed dissolution of aluminum in nitric acid, It was designed to utilize the heat of reaction and evolution of gaseous reaction products for recirculation and mixing. The dissolvent was 5-molar nitric acid, containing mercury in concentrations from 10/sup -4/ to 10/sup -3/ molar as a catalyst. Dissolution rates for 1/7 scale, simulated MTR fuel elements of 2-S aluminum ranged from 0.25 to 4.0 mg/(cm/sup 2/)(rain), depending on the catalyst concentration in the dissolvent and the dissolvent flow rate. For comparable catalyst and acid feed concentrations, dissolution rates, based on unit net superficial velocities, were nearly 25 times those for dissolution of randomly- packed flat plates in a pilot plant, continuous, flooded dissolver.

Army Networks: Size and Scope of Modernization Investment Merit Increased Oversight
A letter report issued by the Government Accountability Office with an abstract that begins "The Army has taken a number of steps to begin executing its network strategy and agile process, including establishing a baseline network architecture for Army communications. The Army's agile process involves seven phases and three decision points to allow officials to quickly evaluate emerging networking technologies to determine if they address capability gaps and can be deployed to the field. However, the network strategy is still evolving and the Army has not yet executed one full cycle of the agile process. The Army's strategy addresses some aspects of cost, technology maturity, security, and readiness, but as implementation is still under way, data for assessing progress are not available at this time. Nevertheless, the Army is beginning to spend billions of dollars netting together dozens of disparate systems to form a network that is intended to enhance warfighter effectiveness and survivability. Specifically, the Army has identified that over $3 billion will be needed each year on an indefinite basis for investments in networking capabilities, potentially making it one of the Army's most costly investments. To help determine that technologies meet prescribed levels of technical maturity, the Army …

Farm Service Agency: Updated Status of the Multibillion-Dollar Farm Loan Portfolio
A letter report issued by the General Accounting Office with an abstract that begins "The Farm Service Agency (FSA) within the Department of Agriculture provides financial assistance to farmers and ranchers who are unable to obtain commercial credit at reasonable rates and terms. FSA provides direct government-funded loans and repayment guarantees on farm loans made by commercial lenders. During the 1990s, GAO issued a series of reports highlighting the substantial financial risk associated with FSA's farm loan programs and multibillion-dollar portfolio. GAO recently reviewed FSA's farm loan programs to determine the outstanding principal owed on direct and guaranteed farm loans at the end of fiscal year 2000 and the losses incurred by FSA on direct and guaranteed farm loans in the same year. GAO found that FSA had more than $16.6 billion in outstanding farm loans as of September 2000. Farm loan losses incurred by FSA during fiscal year 2000 totalled about $486 million. Both figures represent a significant decrease when compared to figures for earlier years."

Health Information Technology: Early Efforts Initiated but Comprehensive Privacy Approach Needed for National Strategy
A letter report issued by the Government Accountability Office with an abstract that begins "The expanding implementation of health information technology (IT) and electronic health information exchange networks raises concerns regarding the extent to which the privacy of individuals' electronic health information is protected. In April 2004, President Bush called for the Department of Health and Human Services (HHS) to develop and implement a strategic plan to guide the nationwide implementation of health IT. The plan is to recommend methods to ensure the privacy of electronic health information. GAO was asked to describe HHS's efforts to ensure privacy as part of its national strategy and to identify challenges associated with protecting electronic personal health information. To do this, GAO assessed relevant HHS privacy-related initiatives and analyzed information from health information organizations."

U.S.-China Trade: Eliminating Nonmarket Economy Methodology Would Lower Antidumping Duties for Some Chinese Companies
A letter report issued by the Government Accountability Office with an abstract that begins "U.S. companies adversely affected by unfair imports may seek a number of relief measures, including antidumping (AD) duties. The Department of Commerce (Commerce) classifies China as a nonmarket economy (NME) and uses a special methodology that is commonly believed to produce AD duty rates that are higher than those applied to market economies. Commerce may stop applying its NME methodology if it finds that China warrants designation as a market economy. In light of increased concern about China's trade practices, the conference report on fiscal year 2004 appropriations requested that GAO review efforts by U.S. government agencies responsible for ensuring free and fair trade with that country. In this report, the last in a series, GAO (1) explains the NME methodology, (2) analyzes AD duties applied to China and compares them with duties applied to market economies, and (3) explains circumstances in which the United States would stop applying its NME methodology to China and evaluates the potential impact of such a step. Commerce agreed with our findings, commenting that our report provides timely and helpful information on the NME methodology and its application to China."

Tax Administration: Electronic Filing's Past and Future Impact on Processing Costs Dependent on Several Factors
A letter report issued by the General Accounting Office with an abstract that begins "From fiscal years 1997 through 2000, the number of individual and business tax returns filed electronically increased from 23 million to 41 million. During the same period, the Internal Revenue Service's (IRS) expenditures for submission processing grew from $795 million to $924 million, an increase of 16 percent. Because it costs less to process an electronic return than a paper return, a growth in processing costs seemed improbable. Interviews with IRS officials and an analysis of relevant documentation identified several factors that limited the impact of electronic filing. Specifically, (1) the overall number of individual and business tax returns filed increased, and the resources needed to process that increase partially offset the resources saved by processing more electronic returns; (2) the number of the most costly to process individual income tax returns filed on paper essentially stayed the same; and (3) the number of individual income tax returns filed on paper and received during the peak filing period stayed relatively the same, and peak processing needs drive the resources needed to process individual paper returns. Although electronic filing increased, so did the demands placed on paper …

Aviation Safety: Undeclared Air Shipments of Dangerous Goods and DOT's Enforcement Approach
A letter report issued by the General Accounting Office with an abstract that begins "When shipments of dangerous goods (hazardous chemical substances that could endanger public safety or the environment, such as flammable liquids or radioactive materials) are not properly packaged and labeled for air transport, they can pose significant threats because there is little room for error when something goes wrong in flight. To better understand the risks posed by improper ("undeclared") air shipments, we assessed what is known about their nature and frequency, what key mechanisms are in place to prevent their occurrence, and what the Department of Transportation (DOT) and the Postal Service do to enforce federal regulations for shipping dangerous goods by air."

Federal Employees' Health Benefits: Effects of Using Pharmacy Benefit Managers on Health Plans, Enrollees, and Pharmacies
A letter report issued by the General Accounting Office with an abstract that begins "Rising prescription drug costs have contributed to rising employer health plans premiums in recent years. Most federal employees, retirees, and their dependents participating in the Federal Employees Health Benefits Program (FEHBP), administered by the Office of Personnel Management (OPM), are enrolled in plans that contract with pharmacy benefit managers (PBM) to administer their prescription drug benefits. GAO was asked to examine how pharmacy benefits managers participating in the federal program affect health plans, enrollees, and pharmacies. GAO examined the use of PBMs by three plans representing about 55 percent of the 8.3 million people covered by FEHBP plans. For example, GAO surveyed 36 retail pharmacies on prices that a customer without third party coverage would pay for 18 high-volume or high-expenditure drugs and compared these prices to prices paid by the plans and PBMs."

Medicare: Payment for Blood Clotting Factor Exceeds Providers' Acquisition Cost
A letter report issued by the General Accounting Office with an abstract that begins "In 2001, Medicare's outpatient expenditures for blood clotting factor used to treat the estimated 1,100 beneficiaries with hemophilia totaled about $105 million, or more than 2 percent of total Medicare spending on outpatient drugs. Earlier work by GAO indicated that Medicare's payment for certain outpatient drugs is substantially higher than providers' acquisition costs. Concerns have been raised about Medicare's payment for blood clotting factor. GAO was asked to compare provider costs of purchasing clotting factor with Medicare's payment for it and to identify costs to providers associated with delivering clotting factor."
