Preliminary characterization of the F-Area Railroad Crosstie Pile at the Savannah River Site. Revision 1
Historical information about the F-Area Railroad Crosstie Pile is limited. The unit is believed to have been a borrow area for earth fill that began receiving railroad crossties during the 1960s. The number of crossties at the unit began to increase significantly in 1984 when major repair of the SRS rail system was initiated. An estimated 100,000 used railroad crossties have accumulated at the unit since 1984. In an effort to determine the impact of the railroad crossties on the environment a total of 28 soil samples were collected from four test borings in March of 1991. Sample depths ranged from ground surface to 21.5 feet. Three of the borings were extended to the water table and groundwater samples were collected, one in an upgradient ``background`` area, and two downgradient from the unit. Few analytes were reported above detection limits. Test results are summarized in Section 4.0 and analytes not detected are summarized in Appendix A to this report. In three soil samples collected from depths between 10 and 21.5 feet, copper occurred at levels slightly above background. These copper values were detected in the sidegradient test boring and in the two downgradient test borings. Three organic analytes, acetone, pyridine, …

Preliminary performance assessment strategy for single-shell tank waste disposal
The disposal of the waste stored in single-shell tanks at the Hanford Site is recognized as a major environmental concern. A comprehensive program has been initiated to evaluate the various alternatives available for disposal of these wastes. Theses wastes will be disposed of in a manner consistent with applicable laws and regulations. Long-term waste isolation is one measure of performance that will be used for purposes of selection. The performance of each disposal alternative will be simulated using numerical models. Contained herein is a discussion of the strategy that has and continues to evolve to establish a general analytical framework to evaluate this performance. This general framework will be used to construct individual models of each waste disposal alternative selected for purposes of evaluation. 30 refs., 3 figs.

Present status of computational tools for maglev development
High-speed vehicles that employ magnetic levitation (maglev) have received great attention worldwide as a means of relieving both highway and air-traffic congestion. At this time, Japan and Germany are leading the development of maglev. After fifteen years of inactivity that is attributed to technical policy decisions, the federal government of the United States has reconsidered the possibility of using maglev in the United States. The National Maglev Initiative (NMI) was established in May 1990 to assess the potential of maglev in the United States. One of the tasks of the NMI, which is also the objective of this report, is to determine the status of existing computer software that can be applied to maglev-related problems. The computational problems involved in maglev assessment, research, and development can be classified into two categories: electromagnetic and mechanical. Because most maglev problems are complicated and difficult to solve analytically, proper numerical methods are needed to find solutions. To determine the status of maglev-related software, developers and users of computer codes were surveyed. The results of the survey are described in this report. 25 refs.

Problems in mechanistic theoretical models for cell transformation by ionizing radiation
A mechanistic model based on yields of double strand breaks has been developed to determine the dose response curves for cell transformation frequencies. At its present stage the model is applicable to immortal cell lines and to various qualities (X-rays, Neon and Iron) of ionizing radiation. Presently, we have considered four types of processes which can lead to activation phenomena: (1) point mutation events on a regulatory segment of selected oncogenes, (2) inactivation of suppressor genes, through point mutation, (3) deletion of a suppressor gene by a single track, and (4) deletion of a suppressor gene by two tracks.

Procedure development study: Low strain rate and creep experiments; Yucca Mountain Site Characterization Project
Licensing of the potential nuclear-waste repository at Yucca Mountain by the Nuclear Regulatory Commission would require, among other things, demonstrations of the long term usability of the underground facilities. Such a demonstration involves analysis of the mechanical response of the rock to the presence of underground openings and heat-producing waste, which in turn requires data on the mechanical properties of the rock. This document describes the experimental results from a scoping study which led to the development of procedures for performing quality-affecting rock-mechanics experiments on intact rock. The future experiments performed with these procedures will produce information on the time-dependent deformation of welded tuff and represent one aspect of the overall effort to characterize the rheology of the rock mass. 3 refs., 42 figs., 6 tabs.

Proceedings of the third conference on radiation protection and dosimetry
The Third Conference on Radiation Protection and Dosimetry was held during October 21--24, 1991, at the Sheraton Plaza Hotel in Orlando, Florida. This meeting was designed with the objectives of promoting communication among applied, research, regulatory, and standards personnel involved in radiation protection, and providing them with sufficient information to evaluate their programs. To meet these objectives, a technical program consisting of more than 75 invited and contributed oral presentations encompassing all aspects of radiation protection was prepared. General topics considered in the technical session included external dosimetry, internal dosimetry, instruments, accident dosimetry, regulations and standards, research advances, and applied program experience. In addition, special sessions were held to afford attendees the opportunity to make short presentations of recent work or to discuss topics of general interest. Individual reports are processed separately on the database.

Processing and properties of superconductor wires
Variables in fabrication of superconductor wires by extrusion and by powder-in-tube processing are discussed. Decomposition of plastically extruded YBCO is minimized by firing at reduced total pressure. Extruded wires of YBCO were densified with fine-grained microstructures by sintering at an oxygen partial pressure of 10{sup {minus}3} MPa. A reduction in average grain size from 23 to 4 {mu}m increased strength from 83 to 191 MPa. Addition of 15 vol. % Ag particles further increased the strength to 220 MPa, with the increase resulting from compressive stresses in YBCO matrix due to the Ag. In powder-in-tube processing, primary considerations are the mechanical-working and heating schedules. The best properties in Ag-clad Bi-based superconductors were obtained with many small reductions during working and by use of liquid-phase formation during sintering to promote grain growth. 12 refs., 3 figs., 1 tab.

Product assurance planning in an environment of increased need for accountability
Projects producing data are too often providing a product that is neither defensible nor usable. Instead of planning for data of known and required quality, managers are too often asking for (and getting) the wrong thing. The problem is a lack of correct planning strategy. A planning strategy to produce usable, defensible data requires communication from the customer to top-level management and from top-level management to the project leader, who must then communicate with the technical experts who will run the project. EPA requires that data quality objectives (DQOs) be derived for RI/FS projects. The DQO process is a top-down planning process that requires two-way communication; some organizations do not have structures suited for implementing DQOs as mandated by EPA. This paper discusses specific tools for imposing structure that will make the DQO process easier to follow for many organizations. The tools include a steering committee, a test design team, and Quality Function Deployment (QFD) matrices. The steering committee is a strong technical forum that can develop technical issues systematically and break down technical issues into manageable pieces that can be stated as test objectives. The test design team plans each test, systematically designs the test matrix, and guides the …

The production and use of radioactive nuclear beams at the Bevalac
Using the fragmentation process, radioactive nuclear beams (RNB) are routinely produced at the Lawrence Berkeley Laboratory's Bevalac. Three beam lines are operational for production and transport of RNB: (1) a line for use in the radiotherapy treatment program (A {congruent} 20 amu), (2) a line for low mass (A {congruent} 20 amu) nuclear science studies and (3) a line for medium mass (A {congruent} 50 amu) nuclear science studies. A fourth beam line is under construction that will allow higher mass RNB (A {congruent} 100 amu) to be transmitted to the Bevalac's Heavy Ion Superconducting Spectrometer. Characteristics of RNB production and transport efficiency are described along with the RNB experimental program at the Bevalac.

Progress in evaluating the corrosion of candidate HLW container metals in irradiated air-steam mixtures
The Yucca Mountain Site Characterization Project is evaluating Yucca Mountain in Nye County, Nevada, as a site for a potential high-level nuclear waste repository. Lawrence Livermore National Laboratory is concerned with the development and performance modeling of waste packages for the potential repository. Argonne National Laboratory has performed experimental studies in support of the waste package effort. This effort is currently guided by the Waste Package Plan, which calls for a systems engineering approach to waste package development. Part of this approach involves formulating an approved set of selection criteria to choose the materials to be used in fabricating the waste packages. Technical issues related to the performance of metals in the air/water vapor environment expected in the potential Yucca Mountain repository are discussed. Preliminary experiments, focused on the atmospheric corrosion of copper-based materials, are summarized. These experiments were performed over a broad range of conditions: temperatures between 90 and 150{degrees}C; relative humidities of 0, 15, 40, and 100%; and gamma dose rates between 0.01 and 0.3 Mrad/hr. In irradiated moist air, copper-based materials form cooper oxides and nitrate phases depending on the dose rate, humidity and temperature. The rates of general corrosion increase with temperature, humidity, and dose rate. …

Progress in evaluation and improvement in nondestructive examination reliability for inservice inspection of Light Water Reactors (LWRs) and characterize fabrication flaws in reactor pressure vessels
This paper is a review of the work conducted under two programs. One (NDE Reliability Program) is a multi-year program addressing the reliability of nondestructive evaluation (NDE) for the inservice inspection (ISI) of light water reactor components. This program examines the reliability of current NDE, the effectiveness of evolving technologies, and provides assessments and recommendations to ensure that the NDE is applied at the right time, in the right place with sufficient effectiveness that defects of importance to structural integrity will be reliably detected and accurately characterized. The second program (Characterizing Fabrication Flaws in Reactor Pressure Vessels) is assembling a data base to quantify the distribution of fabrication flaws that exist in US nuclear reactor pressure vessels with respect to density, size, type, and location. These programs will be discussed as two separate sections in this report. 4 refs., 7 figs.
