Radioactive waste is scheduled to be retrieved from Hanford double-shell tanks AN-103, AN-104, AN-105 and AW-101 to the vitrification plant beginning about 2009. Retrieval may involve decanting the supernatant liquid and/or mixing the waste with jet pumps. In these four tanks, which contain relatively large volumes of retained gas, both of these operations are expected to induce buoyant displacement gas releases that can potentially raise the tank headspace hydrogen concentration to very near the lower flammability limit. This report describes the theory and detailed physical models for both the supernate decant and jet mixing processes and presents the results from applying the models to these operations in the four tanks. The technical bases for input parameter distributions are elucidated.

Correspondence issued by the General Accounting Office with an abstract that begins "GAO reviewed the Bureau of Prisons to determine whether it had made overpayments to contractors. During fiscal year 2001, the Bureau of Prisons had 24 open construction contracts that totaled about $1.9 billion. In addition to general disbursement controls, GAO found internal controls specific to construction contracts in which both the project representative and the contracting officer must approve each monthly progress payment invoice. GAO sampled 27 payments on five construction contracts to determine if construction contract payment controls were properly designed, in place, and operating to prevent or detect overpayments. GAO found that the internal controls were in place and operating and construction contract payment amounts were correct, or, if errors occurred, they were detected and corrected promptly as a normal part of the payment system. A few minor clerical errors were subsequently detected and corrected by the Bureau of Prisons through its own routine control procedures before GAO made its review. GAO concludes that the risk of undetected construction contractor overpayments at the Bureau of Prisons appears to be small."

We compare the Implicit Monte Carlo (IMC) technique to the Symbolic IMC (SIMC) technique, with and without weight vectors in frequency space, for time-dependent line transport in the presence of collisional pumping. We examine the efficiency and accuracy of the IMC and SIMC methods for examples involving the evolution of a collisionally pumped trapping problem to steady-state, the surface heating of cold media by a beam, and the diffusion of energy from a localized region that is collisionally pumped. The importance of spatial biasing and teleportation for problems involving high opacity is demonstrated. Our numerical solution, along with its associated teleportation error, is checked against theoretical calculations for the last example.

The Institute for Mathematics and its Applications (IMA) was awarded a grant by the Department of Energy that provided partial support for the IMA Career Workshop: Connecting Women in Mathematical Sciences to Industry. The workshop took place on September 8 to 10, 2000 at the IMA was co-sponsored by the Association for Women in Mathematics (AWM), and also received additional funding from Coastcom. This report highlights the activities and the accomplishments of the program.

The DOE is faced with a wide variety of waste treatment problems throughout the complex. The diversity in physical, chemical, and radiological characteristics of these waste streams will necessitate an array of treatment technologies since, at present, there exists no single solution. Thermal treatment technologies have an important, but by no means singular, role to play in addressing this problem since they generally offer the potential for significant volume reductions, leach resistant waste forms, considerable versatility, and are relatively well developed. In particular, DOE has made significant investments in the development and deployment of vitrification technologies for the treatment of high-level nuclear wastes and, more recently, for mixed wastes. The general area of materials of construction is especially important for thermal processes due to the inherently high-temperature and the often-corrosive environments involved. The performance of these materials directly impacts treatment costs since this determines maintenance downtime and the useful service life of the treatment unit.

Laboratory experiments on wave propagation through saturated and partially saturated porous media have often been conducted on porous cylinders that were initially fully saturated and then allowed to dry while continuing to acquire data on the wave behavior. Since it is known that drying typically progresses from the outside to the inside, a sensible physical model of this process is concentric cylinders having different saturation levels--the simplest example being a fully dry outer cylindrical shell together with a fully wet inner cylinder. We use this model to formulate the equations for wave dispersion in porous cylinders for patchy saturation (i.e., drainage) conditions. In addition to multiple modes of propagation obtained numerically from these dispersion relations, we find two distinct analytical expressions for torsional wave modes.

Testimony issued by the General Accounting Office with an abstract that begins "Financial management problems at the Department of Defense (DOD) are complex, long-standing, and deeply rooted throughout its business operations. DOD's financial management deficiencies represent the single largest obstacle to achieving an unqualified opinion on the U.S. government's consolidated financial statements. So far, none of the military services or major DOD components have passed the test of an independent financial audit because of pervasive weaknesses in financial management systems, operations, and controls. These problems go back decades, and earlier attempts at reform have been unsuccessful. DOD continues to rely on a far-flung, complex network of finance, logistics, personnel, acquisition, and other management information systems for financial data to support day-to-day management and decision-making. This network has evolved into an overly complex and error-prone operation with (1) little standardization across DOD components; (2) multiple systems performing the same tasks; (3) the same data stored in multiple systems; (4) manual data entry into multiple systems; and (5) a large number of data translations and interfaces, which combine to exacerbate problems with data integrity. Many of the elements that are crucial to financial management reform and business process transformation--particularly those that rely …

Millions of gallons of radioactive waste are stored in large underground tanks at DOE sites. The waste is made up of settled solids, in sludge form, at the bottom of the tank and a layer of supernatant liquid on top of it. It is necessary to mix the solids in the sludge layer with the supernatant liquid to facilitate their removal from the storage tanks for remediation. Our goal is to improve the mobilization of the settled solids by optimizing mixing with the supernatant liquid and preserving the mobility of the solids. This report investigates whether time-phase separation between pump head oscillations affects overall sludge mobilization. If a mixing jet from one pump happens to follow temporarily the path of the lead mixing jet, it may be possible to prevent or slow down the resettling of the heavy solid particles, maintaining them in suspension. If a retrieval pump were operating at the same time, it could facilitate removal of such particles. Preliminary experiments were carried out to observe whether time-phase separation has some influence on the overall mobilization. A brief account is presented of the successful mobilization and removal of most of the radioactive waste from Tank D8-2 at the …

Part of the U.S. Initiative on Joint Implementation with the Ukraine Inter-Ministerial Commission on Climate Change, financed by the US Department of Energy. The project was implemented by a team consisting of the US company SenTech, Inc. and the Ukrainian company Esco-West. The main objective of the effort was to assess available alternatives of Ivano-Frankivsk (I-F) District Heating repowering and provide information for I-F's investment decision process. This study provides information on positive and negative technical and economic aspects of available options. Three options were analyzed for technical merit and economic performance: 1. Installation of cogeneration system based on Gas Turbine (GT) and Heat Recovery Heat Exchanger with thermal capacity of 30 MW and electrical capacity of 13.5 MW. This Option assumes utilization of five existing boilers with total capacity of 221 MW. Existing boilers will be equipped with modern controls. Equipment in this Option was sized for longest operating hours, about 8000 based on the available summer baseload. 2. Installation of Gas Turbine Combined Cycle (GTCC) and Heat Recovery Steam Generator (HRSG) with thermal capacity 45 MW and electrical capacity of 58.7 MW. This Option assumes utilization of five existing boilers with total capacity of 221 MW. Existing boilers …

Testimony issued by the General Accounting Office with an abstract that begins "The Highway Trust Fund "guarantees" specific annual funding levels for most highway programs on the basis of projected receipts to the fund. It also makes annual adjustments to these funding levels on the basis of actual receipts and revised projections of trust fund revenue. These adjustments are called the Revenue Aligned Budget Authority (RABA). GAO concludes that the fiscal year 2003 RABA calculation appears reasonable. Although the RABA adjustment is clearly severe, it reflects the many ways in which an economic downturn affects the calculation. In late January 2002, the administration announced that the fiscal year 2003 RABA adjustment would be a negative $4.965 billion. Within a few days of the announcement, the administration reported that an error had been made and the correct amount was a negative $4.369 billion--a $600 million difference. Treasury is taking steps to improve its internal controls in order to prevent this type of error from reoccurring. The use of ethanol blended fuel instead of gasoline reduces Highway Trust Fund revenue because it is partially exempt from the standard excise tax on gasoline and 2.5 cents of the tax received on each gallon …
