The objective of this calculation is to determine the structural response of a 21-Pressurized Water Reactor (PWR) spent nuclear fuel waste package impacting an unyielding surface. A range of initial velocities and initial angles between the waste package and the unyielding surface is studied. The scope of this calculation is limited to estimating the area of the outer shell (OS) where the residual stress exceeds a given limit (hereafter ''damaged area''). The stress limit is defined as a fraction of the yield strength of the OS material, Alloy 22 (SB-575 N06022), at the appropriate temperature. The design of the 21-PWR waste package used in this calculation is that defined in Reference 8. However, a value of 4 mm was used for the gap between the inner shell and the OS, and the thickness of the OS was reduced by 2 mm. The sketch in Attachment I provides additional information not included in Reference 8. All obtained results are valid for this design only. This calculation is associated with the waste package design and was performed by the Specialty Analyses and Waste Package Design Section. The waste package (i.e. uncanistered spent nuclear fuel disposal container) is classified as Quality Level 1.

Automatika, Inc. was contracted by the Department of Energy (DOE) and with co-funding from the New York Gas Group (NYGAS), to develop an in-pipe natural gas prototype measurement and wireless communications system for assessing and monitoring distribution networks. A prototype system was built for low-pressure cast-iron mains and tested in a spider- and serial-network configuration in a live network in Long Island with the support of Keyspan Energy, Inc. The prototype unit combined sensors capable of monitoring pressure, flow, humidity, temperature and vibration, which were sampled and combined in data-packages in an in-pipe master-slave architecture to collect data from a distributed spider-arrangement, and in a master-repeater-slave configuration in serial or ladder-network arrangements. It was found that the system was capable of performing all data-sampling and collection as expected, yielding interesting results as to flow-dynamics and vibration-detection. Wireless in-pipe communications were shown to be feasible and valuable data was collected in order to determine how to improve on range and data-quality in the future.

The project was highlighted by continued fabrication of drill bit inserts and testing them: (1) The inserts were subjected to hammer tests to determine brittleness. Selected inserts experienced multiple blows from a 16 pound sledge hammer. The resulting damage was minimal. (2) Three inserts were placed on three different 16.5 inch diameter rotary drill bits, and the bits drilled taconite rock until the entire bit failed. (3) The inserts had somewhat less wear resistance than current art, and exhibited no brittle failures. (4) More work is needed to produce the inserts at near net shape. The test inserts required too much machining. The project next turned to manufacturing 6.5 inch diameter disc cutters. The cutters will feature a core of tungsten carbide (TC) in a disc body composed of H13 tool steel. The TC inserts are in manufacture and the dies for the disc are being designed. The plan for next quarter: (1) Investigate materials and manufacturing changes for the fibrous monolith drill bit inserts that will increase their wear life. (2) Begin manufacturing disc cutters.

The overall goal of this project was to develop reliable cost effective sensors for application in the down-hole environment. The physical parameters measured by these sensors were temperature, pressure, flow and acoustic signals. Sensor head configurations for each of the physical measurands were optimized to increase the sensitivity to the particular measurand of interest while decreasing the cross-sensitivity to the other physical measurands and to environmental influences. In addition, the optical signal demodulation electronics was designed to be insensitive to environmental influences while maintaining the required resolution, precision and accuracy of the parameter being sensed. The influence of potentially detrimental agents such as water in the down-hole environment was investigated as well as methods to protect both the optical fiber and the sensor from these detrimental effects.

Naturally occurring 222-radon in ground water can potentially be used as an in situ partitioning tracer to characterize dense nonaqueous phase liquid (DNAPL) saturations. The static method involves comparing radon concentrations in water samples from DNAPL-contaminated and non-contaminated portions of an aquifer. During a push-pull test, a known volume of test solution (radon-free water containing a conservation tracer) is first injected (''pushed'') into a well; flow is then reversed and the test solution/groundwater mixture is extracted (''pulled'') from the same well. In the presence of NAPL radon transport is retarded relative to the conservative tracer. Assuming linear equilibrium partitioning, retardation factors for radon can be used to estimate NAPL saturations.The utility of this methodology was evaluated in laboratory and field settings.

A letter report issued by the General Accounting Office with an abstract that begins "Employers with defined benefit plans have expressed concern that low interest rates were affecting the reasonableness of their pension calculations used to determine funding requirements under the Employee Retirement and Income Security Act of 1974 (ERISA). ERISA requires employers to use a variation of the 30-year Treasury bond rate for these calculations; however, in 2001 Treasury stopped issuing the 30-year bond. This report provides information on (1) what characteristics of an interest rate make it suitable for determining current liability and lump-sum amounts; (2) what alternatives to the current rate might be considered; and (3) how using an alternative rate might affect plan participants, employers, and the Pension Benefit Guaranty Corporation (PBGC)."

Appropriations are one part of a complex federal budget process that includes budget resolutions, appropriations (regular, supplemental, and continuing) bills, rescissions, and budget reconciliation bills. This report is a guide to one of the 13 regular appropriations bills that Congress passes each year. It is designed to supplement the information provided by the House and Senate Appropriations Subcommittees on Energy and Water.

Most Elementary and Secondary Education Act (ESEA) programs, including the 21st Century Community Learning Centers (21st CCLC) program, expired at the end of FY2000.1 Included in the No Child Left Behind Act is the reauthorization of the 21st CCLC, with, a new location (Title IV, Part B, 21st Century Schools), and several substantive changes. On December 13 and 18, 2001, respectively, the House and Senate adopted the conference version of H.R. 1, The No Child Left Behind Act. The President signed H.R. 1 into law (P.L. 107-110) on January 8, 2002. This report summarizes the major provisions of the reauthorized 21st CCLC program. The reauthorized program is structured as a formula grant program to states, in response to concerns that a program as large as the 21st CCLC could no longer be equitably administered as a competitive grant program. In addition, the reauthorized program formally endorses a focus for the 21st CCLC on after-school hours activities for children and youth.

Financial distress is most common among lower-income families, but its incidence has grown in all income brackets. This trend suggests that explanations for the rise in consumer bankruptcy filings are more likely to be found in micro-analysis of individuals and groups of debtors than in macroeconomic indicators. This report presents statistics on bankruptcy filings, household debt, and households in financial distress.

This report presents an overview of the Armenia-Azerbaijan conflict. This is a clash between the principles of territorial integrity and self-determination that is occurring in the Caucasus, creating the longest inter-ethnic dispute in the former Soviet Union. The report includes the background and analysis of history, warfare and peace process in the region. The report discusses the Armenian and Azerbaijani perspective, the role and views of others (Iran, Turkey, Russia), as well as the U.S. policy regarding the conflict.
