Building public trust and confidence through openness is a goal of the DOE Carlsbad Field Office for the Waste Isolation Pilot Plant (WIPP). The objective of the virtual document described in this paper is to give the public an overview of the waste characterization steps, an understanding of how waste characterization instrumentation works, and the type and amount of data generated from a batch of drums. The document is intended to be published on a web page and/or distributed at public meetings on CDs. Users may gain as much information as they desire regarding the transuranic (TRU) waste characterization program, starting at the highest level requirements (drivers) and progressing to more and more detail regarding how the requirements are met. Included are links to: drivers (which include laws, permits and DOE Orders); various characterization steps required for transportation and disposal under WIPP's Hazardous Waste Facility Permit; physical/chemical basis for each characterization method; types of data produced; and quality assurance process that accompanies each measurement. Examples of each type of characterization method in use across the DOE complex are included. The original skeleton of the document was constructed in a PowerPoint presentation and included descriptions of each section of the waste …

This report describes the monitoring activities conducted and presents the results of groundwater sampling and water-level measurements from October 2000 to September 2001. Groundwater samples were initially collected from 41 wells from the Idaho Nuclear Technology and Engineering Center and the Central Facilities Area and analyzed for iodine- 129, strontium-90, tritium, gross alpha, gross beta, technetium-99, uranium isotopes, plutonium isotopes, neptunium-237, gamma spectrometry, and mercury. Samples from 41 wells were collected in April and May 2001. Additional sampling was conducted in August 2001 and included in two CFA production wells, the CFA point of compliance for the production wells, one well was previously sampled and five additional monitoring wells. Water-level measurements were taken from in the Idaho Nuclear Technology and Engineering Center, Central Facilities Area, and the area south of Central Facilities Area to evaluate groundwater flow directions. Water-level measurements indicated groundwater flow to the south-southwest from the Idaho Nuclear Technology and Engineering Center.

The management of the Spent Nuclear Fuel (SNF) project at the Hanford K-Basin in the 100 N Area has successfully restructured the preventive maintenance, spare parts inventory requirements, and the operator rounds data requirements. In this investigation, they continue to examine the different facets of the operations and maintenance (O&M) of the K-Basin cleanup project in search of additional reliability and cost savings. This report focuses on the initial findings of a team of PNNL engineers engaged to identify potential opportunities for reducing the cost of O&M through the application of advanced diagnostics (fault determination) and prognostics (residual life/reliability determination). The objective is to introduce predictive technologies to eliminate or reduce high impact equipment failures. The PNNL team in conjunction with the SNF engineers found the following major opportunities for cost reduction and/or enhancing reliability: (1) Provide data routing and automated analysis from existing detection systems to a display center that will engage the operations and engineering team. This display will be operator intuitive with system alarms and integrated diagnostic capability. (2) Change operating methods to reduce major transients induced in critical equipment. This would reduce stress levels on critical equipment. (3) Install a limited sensor set on failure prone …

Automatic measurement of radioactivity is necessary for considering cost effectiveness in final radiological survey of building structures in decommissioning nuclear facilities. The RAPID (radiation measuring pilot device for surface contamination) was developed to be applied to automatic measurement of low level contamination on concrete surfaces. The RAPID has a capability to measure contamination with detection limit of 0.14 Bq/cm2 for 60Co in 30 seconds of measurement time and its efficiency is evaluated to be 5 m2/h in a normal measurement option. It was confirmed that low level contamination on concrete surfaces could be surveyed by the RAPID efficiently compared with direct measurement by workers through its actual application.

A destructive examination of a B-25 waste storage container that was buried in a shallow non-radiological land burial facility for approximately 8 years showed that pitting was the most prevalent form of corrosion and suggested that continued burial would result in through-wall pits after 30 years. This result suggests that through wall pits will provide a path for water flow into and out of similar B-25 containers after approximately 30 years of burial. Pitting was the most severe on the exterior of the lid. However, the lid had collapsed into the container, probably because the soil loading exceeded the support capacity of the lid. This observation demonstrates that lid strength is a significant factor when assessing structural integrity of the B-25 containers. The lid had collapse had allowed the container to fill with soil and water. A review of procurement specifications for the B-25 containers suggest that the container examined in this work was purchased from an earlier ve rsion of the B-25 container procurement specification.

Argentina will require new sites for the location of radioactive waste final disposal systems. It is currently mandatory to have social and political consensus to obtain the corresponding agreements. The experience obtained with the cancellation of the project ''Feasibility Study and Engineering Project--Repository for High Level Radioactive Waste'', reinforces even more the necessity to count with the acceptance of the public to carry out projects of this kind. The first phase of the former was developed in the 80's: geological, geophysical and hydrogeological studies were performed in a compact granitic rock located in Sierra del Medio, Chubut province. This project had to be called off in the early 90's due to strong social rejection. This decision was closely related to the poor attention given to social communication issues. The governmental decision-makers in charge underwent a lot of pressure from social groups claiming for the cancellation of the project due to the lack of information and the fear it triggered. Thus, the lesson learnt: ''social communication activities must be carefully undertaken in order to achieve the appropriate management of the radioactive waste produced in our country.'' The same as in other countries, the specific National Law demands the formulation of a …

A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the Internal Revenue Service's (IRS) fifth expenditure plan requesting $391 million from its Business Systems Modernization (BSM) fund. Although IRS's November 2001 expenditure plan satisfied the conditions specified in the appropriations act, IRS must still fully implement the controls and capabilities described in the plan. Since GAO's June 2001 report, IRS has made important progress in implementing modernization management controls and capabilities and addressing GAO's past recommendations. However, IRS's modernization management capacity is still not where it needs to be. Examples of modernization management controls and capabilities that are not yet fully implemented include software acquisition management, configuration management, quality assurance, risk management, enterprise architecture implementation, human capital management, integrated program scheduling, and cost and schedule estimating. The increased risk of IRS's proceeding without these controls and capabilities has contributed to project cost, schedule, and performance shortfalls. IRS acknowledges that it needs to strengthen its modernization management controls. IRS recognizes that these controls become more critical as the size and complexity of the BSM program continue to increase. Although IRS has actions underway to fully implement these controls, IRS plans to compensate for their …

This report describes the calculation method developed for the projection of future utility spent nuclear fuel (SNF) discharges in regard to their timing, quantity, burnup, and initial enrichment. This projection method complements the utility-supplied RW-859 data on historic discharges and short-term projections of SNF discharges by providing long-term projections that complete the total life cycle of discharges for each of the current U.S. nuclear power reactors. The method was initially developed in mid-1999 to update the SNF discharge projection associated with the 1995 RW-859 utility survey (CRWMS M&O 1996). and was further developed as described in Rev. 00 of this report (CRWMS M&O 2001a). Primary input to the projection of SNF discharges is the utility projection of the next five discharges from each nuclear unit, which is provided via the revised final version of the Energy Information Administration (EIA) 1998 RW-859 utility survey (EIA 2000a). The projection calculation method is implemented via a set of Excel 97 spreadsheets. These calculations provide the interface between receipt of the utility five-discharge projections that are provided in the RW-859 survey, and the delivery of projected life-cycle SNF discharge quantities and characteristics in the format requisite for performing logistics analysis to support design of …

This project is a feasibility study for a control system for existing backup generators in South Africa. The strategy is to install a system to enable backup generators (BGs) to be dispatched only when a large generator fails. Using BGs to provide ''ten minute reserve'' will save energy and reduce emissions of greenhouse gases by an estimated nearly 500,000 tons of carbon dioxide per year.

This paper describes efforts that were undertaken to characterize the stresses induced in resistance pinch welds used to contain high pressure gasses.

A key element in the Department of Energy (DOE) strategy for the stabilization, packaging and storage of plutonium-bearing materials involves closure welding of DOE-STD-3013 Outer Containers (3013 container). The 3013 container provides the primary barrier and pressure boundary preventing release of plutonium-bearing materials to the environment. The final closure (closure weld) of the 3013 container must be leaktight, structurally sound and meet DOE STD 3013 specified criteria. This paper focuses on the development, qualification and demonstration of the welding process for the closure welding of Hanford PFP 3013 outer containers.

We have produced single bursts of helicity from the source in the SSPX spheromak in order to study the efficiency of the simplest example of helicity injection. We find that the helicity injection rate can be written in terms of the injected current and an inductance, and that a simple circuit analogue demonstrates unambiguously the relationship of helicity to energy: helicity injection is the addition of inductive loops. While helicity balance points to the conservation of helicity, the electrical efficiency is around 15%. However, in the expulsion of the loop, electrical energy is converted to directional motion, which may be recoverable usefully as heat by collisions, thus the efficiency of the injection process is arguably quite high. Integral to this notion of helicity injection is the idea that reconnection is necessary: without disconnection from the source by a reconnection event, the spheromak fields are just proportional to the injected current. Sometimes the multiple bursts occur spontaneously and cause a step-wise increase in the field (and helicity). However, in all instances when the current remains above the ejection threshold for t > 50 {micro}s, the n=l mode initiates and builds field, although with much reduced efficiency, and to a level which …

Predator removal is one of the oldest management tools in existence, with evidence that ancient Greeks used a bounty reward for wolves over 3,000 years ago (Anonymous 1964). Efforts to control predators on fish have been documented in scientific journals for at least 60 years (Eschmeyer 1937; Lagler 1939; Foerster and Ricker 1941; Smith and Swingle 1941; Jeppson and Platts 1959), and has likely been attempted for much longer. Complete eradication of a target species from a body of water has rarely been the objective of predator removal programs, which instead have attempted to eliminate predators from specific areas, to reduce the density or standing stock of predators, or to kill the largest individuals in the population (Meronek et al. 1996). In evaluating management programs that remove only part of a predator population, the compensatory response(s) of the remaining predators must be considered. Some potential compensatory responses by remaining individuals include increased reproductive output, increased growth rate, or increased consumption of certain prey species (Jude et al. 1987). If compensation by predators that remain in the system following a removal effort occurs, it may reduce the effectiveness of the predator control program. Northern pike-minnow Ptychocheilus oregonensis (formerly called northern squawfish) …

This technical progress report describes work performed from June 20 through December 19, 2001, for the project, ''Conformance Improvement Using Gels''. Interest has increased in some new polymeric products that purport to substantially reduce permeability to water while causing minimum permeability reduction to oil. In view of this interest, we are currently studying BJ's Aqua Con. Results from six corefloods revealed that the Aqua Con gelant consistently reduced permeability to water more than that to oil. However, the magnitude of the disproportionate permeability reduction varied significantly for the various experiments. Thus, as with most materials tested to date, the issue of reproducibility and control of the disproportionate permeability remains to be resolved. Concern exists about the ability of gels to resist washout after placement in fractures. We examined whether a width constriction in the middle of a fracture would cause different gel washout behavior upstream versus downstream of the constriction. Tests were performed using a formed Cr(III)-acetate-HPAM gel in a 48-in.-long fracture with three sections of equal length, but with widths of 0.08-, 0.02-, and 0.08-in., respectively. The pressure gradients during gel extrusion (i.e., placement) were similar in the two 0.08-in.-wide fracture sections, even though they were separated by a …

A letter report issued by the General Accounting Office with an abstract that begins "The District of Columbia Courts (DC Courts) is acquiring the Integrated Justice Information System (IJIS) to replace many nonintegrated systems. This system is expected to address current deficiencies and provide the courts with necessary information critical to its mission. DC Courts has not yet implemented the disciplined processes necessary to reduce the risks associated with acquiring and managing the IJIS acquisition effort at acceptable levels within established resources and schedule. Most of the DC Courts' requirements, developed in the draft request for proposal, lacked the specificity needed to ensure that requirements had been reduced to acceptable levels and the system would meet users' needs. DC Courts officials want to use the acquisition process to identify the cost, schedule, and performance gaps associated with their effort. DC Courts officials acknowledge that this approach increases risk; however, they believe that accelerating the implementation of a badly needed system justifies those risks. As with any effort, alternative approaches need to be analyzed."

A letter report issued by the General Accounting Office with an abstract that begins "The Debt Collection Improvement Act of 1996 seeks to maximize the collection of billions of dollars of nontax delinquent debt owed to the federal government. The act requires agencies to refer eligible debts delinquent more than 180 days to the Department of the Treasury for payment offset and to Treasury or a Treasury-designated debt collection center for cross-servicing. The Treasury Offset Program, includes the offset of benefit payments, vendor payments, and tax refunds. Cross-servicing involves locating debtors, issuing demand letters, and referring debts to private collection agencies. The Rural Housing Service (RHS) has initiatives to ensure the timely referral of all delinquent debt. However, the agency's failure to make the act a priority has left key provisions of the legislation unimplemented and severely reduced collection opportunities. The agency had referred no direct single-family housing (SFH) loans to the Financial Management Service for cross-servicing. Three major factors delayed implementation. First, RHS's loan-servicing system had not incorporated key features necessary to implement the act's referral provisions. Second, RHS did not refer any debts for cross-servicing while pursuing an exemption from Treasury. Third, amounts reported as delinquent and eligible …

A letter report issued by the General Accounting Office with an abstract that begins "To improve federal debt collection, the Debt Collection Improvement Act of 1996 established a framework of debt collection tools, including administrative wage garnishment (AWG). This report discusses the extent to which nine agencies use or plan to use AWG to collect delinquent nontax federal debt and provides GAO's perspective on ways to make AWG more widespread and effective. GAO found that none of the nine agencies had yet implemented AWG. Although AWG is not mandatory, by failing to use this tool--more than five years after the act's enactment and more than three years after the Department of the Treasury issued implementing regulations--agencies have missed an opportunity to maximize collection of delinquent debt. Agencies identified various reasons for not yet implementing AWG or for deciding not to do so, including the need to focus their resources on implementing the act's mandatory provisions. Although some agencies or programs may have valid reasons for not implementing wage garnishment, all of the larger programs that deal with individuals and that have a demonstrated risk of financial loss resulting from unpaid debt should have AWG as a viable debt collection option. …

A letter report issued by the General Accounting Office with an abstract that begins "The armed services have significantly reduced their procurement of new weapons systems and are keeping their existing systems longer than originally anticipated. The Department of Defense (DOD) estimates that it is spending $59 billion a year on logistics support to operate and sustain weapons systems, but DOD believes that better logistics support practices could reduce these costs by as much as 20 percent. To cut costs and improve efficiency, the military services have begun implementing logistics support strategies that rely on the private sector. DOD Regulation 5000.2-R expresses a preference for using long-term contractor logistics support but requires that an analysis be done first to determine how logistics support work is to be allocated to public or private entities. It is impossible to determine whether initial cost-effectiveness estimates for proposed contractor-logistics-support approaches are being achieved because the Army and Navy lack the required data. Consequently, the services may be adopting support approaches without knowing whether expected readiness improvements and cost-reduction goals are being met, where adjustments are needed, or the conditions under which the various support approaches are likely to achieve the most cost-effective results. Comparisons …

This report details the results of a demonstration for disposal of the legacy solution containing americium and curium through the High Level Waste system.

A numerical model was developed in order to describe the electromigration of radioelements through contaminated concrete. The transport of several ionic species across a saturated sample of material, is described by the Nernst-Planck relation. The multi species approach provides a better understanding of the phenomena involved: it stresses the need to know, as precisely as possible, the material characteristics and the history of the contamination. The approach also sheds lights on the way the radionuclide (cesium 137) is carried away from a concrete sample during a decontamination simulation.

A hoisting rail system has been designed for lifting loads from the north sidewalk of the D0 collision hall into the collision hall pit. This engineering note documents the design. The hoisting system was conceived primarily to aid in getting heavy loads into the pit during short (less than a few days) accesses. The typical use for the hoist will be to lift a BLS power supply (120 lbs) and carrier (16 lbs) from a roll around cart on the sidewalk and onto a similar cart in the collision hall pit. The hoist system will alleviate the need for two persons to carry this heavy load up and down a narrow (24-inch) staircase. The hoisting system has a designed lift rating of 150 lbs. All members and components are well within a conservative safety factor when subjected to this loading at it's worst possible configuration, that is with it's boom cantilevered out 8 feet from the base rail. See the hoisting rail assembly sketch (in the hand calculations section) and the picture inserted below to get an orientation of the device. The hoisting system is designed using BLine 'unistrut' system components. The hoist consists of a 'base' rail that is …

The Pulp Process (PP) Treatment option was conceived as a replacement for the current Filter Leaching System (FLS). The FLS has operated at the Idaho Nuclear Technology and Engineering Center of the Idaho National Engineering and Environmental Laboratory since 1995 to treat radioactive, mixed waste HEPA filters. In recent years, the FLS has exhibited difficulty in removing mercury from the HEPA filters as the concentration of mercury in the spent HEPA filters has increased. The FLS leaches and washes the whole filter without any preparation or modification. The filter media and the trapped calcine particles are confined in a heavy filter housing that contributes to poor mixing zones around the edges of the filter, low media permeability, channeling of the liquid through cracks and tears in the filter media, and liquid retention between leach and rinse cycles. In the PP, the filter media and the trapped calcine particles are separated from the filter housing and treated as a pulp, taking advantage of improved contact with the leach solution that cannot be achieved when the media is still in the HEPA filter housing. In addition to removing the mercury more effectively, the PP generates less volume of liquid waste, requires a …

In 1997, the U.S. Environmental Protection Agency (EPA) established the ''Heat Island Reduction Initiative'' to quantify the potential benefits of Heat-Island Reduction (HIR) strategies (i.e., shade trees, reflective roofs, reflective pavements and urban vegetation) to reduce cooling-energy use in buildings, lower the ambient air temperature and improve urban air quality in cities, and reduce CO2 emissions from power plants. Under this initiative, the Urban Heat Island Pilot Project (UHIPP) was created with the objective of investigating the potential of HIR strategies in residential and commercial buildings in three initial UHIPP cities: Baton Rouge, LA; Sacramento, CA; and Salt Lake City, UT. Later two other cities, Chicago, IL and Houston, TX were added to the UHIPP. In an earlier report we summarized our efforts to calculate the annual energy savings, peak power avoidance, and annual CO2 reduction obtainable from the introduction of HIR strategies in the initial three cities. This report summarizes the results of our study for Chicago and Houston. In this analysis, we focused on three building types that offer the highest potential savings: single-family residence, office and retail store. Each building type was characterized in detail by vintage and system type (i.e., old and new building constructions, and …

Falling agricultural exports and declining commodity prices led farm groups and agribusiness firms to urge the 106th Congress to pass legislation exempting foods and agricultural commodities from U.S. economic sanctions against certain countries. In completing action on the FY2001 agriculture appropriations bill, Congress codified the lifting of unilateral sanctions on commercial sales of food, agricultural commodities, medicine, and medical products to Iran, Libya, North Korea, and Sudan, and extended this policy to apply to Cuba (Title IX of H.R. 5426, as enacted by P.L. 106-387; Trade Sanctions Reform and Export Enhancement Act of 2000). Related provisions place financing and licensing conditions on sales to these countries. Those that apply to Cuba, though, are permanent and more restrictive than for the other countries. Other provisions give Congress the authority in the future to veto a President's proposal to impose a sanction on the sale of agricultural or medical products.
