1991 Annual performance report for environmental oversight and monitoring at Department of Energy Facilities in New Mexico
On October 22, 1990 an agreement was entered into between the US DOE and the State of New Mexico. The agreement was designed to assure the citizens of New Mexico that the environment is protected and that public health, as related to the environment is also protected. The Agreement reflects the understanding and commitments between the parties regarding environmental oversight, monitoring, remediation and emergency response at the following DOE facilities: the Inhalation Toxicology Research Institute (ITRI); Los Alamos National Laboratory (LANL); Sandia National Laboratory (SNL); and the Waste Isolation Pilot Plant (WIPP). These provision are ongoing through a vigorous program of independent monitoring and oversight; prioritization of clean-up and compliance activities; and new commitments by DOE. While the initial assessment of the quality and effectiveness of the facilities` environmental monitoring and surveillance programs is not yet complete, preliminary findings are presented regarding air quality monitoring, environmental monitoring, and groundwater monitoring.

2607-W6 sanitary drainfield replacement
The septic 2607-W6 which supports the 222-S complex is operating at 200% capacity. The septic tank has been inspected and found to be sound. Test hole excavations of the existing drainfield indicate that it is disposing of the current waste water effluent load as opposed to treating it. The system is over 40 years old and has not been approved by the Washington State Department of Health. Under the existing operating conditions it is subject to imminent failure. No additional tie-ins or increases in personnel are allowed which will increase the flow to the 2607-W6 system.

Accelerated hygrothermal stabilization of composite materials
Experimentation validated a simple moisture conditioning scheme to prepare Gr/Ep composite parts for precision applications by measuring dimensional changes over 90 days. It was shown that an elevated temperature moisture conditioning scheme produced a dimensionally stable part from which precision structures could be built/machined without significant moisture induced dimensional changes after fabrication. Conversely, that unconditioned Gr/Ep composite panels exhibited unacceptably large dimensional changes (i.e., greater than 125 ppM). It was also shown that time required to produce stable parts was shorter, by more than an order of magnitude, employing the conditioning scheme than using no conditioning scheme (46 days versus 1000+ days). Two final use environments were chosen for the experiments: 50% RH/21C and 0% RH/21C. Fiberite 3034K was chosen for its widespread use in aerospace applications. Two typical lay-ups were chosen, one with low sensitivity to hygrothermal distortions and the other high sensitivity: [0, {plus_minus} 45, 90]s, [0, {plus_minus} 15, 0]s. By employing an elevated temperature, constant humidity conditioning scheme, test panels achieved an equilibrium moisture content in less time, by more than an order of magnitude, than panels exposed to the same humidity environment and ambient temperature. Dimensional changes, over 90 days, were up to 4 times lower …

An accurate, efficient algorithm for calculation of quantum transport in extended structures
In device structures with dimensions comparable to carrier inelastic scattering lengths, the quantum nature of carriers will cause interference effects that cannot be modeled by conventional techniques. The basic equations that govern these ``quantum`` circuit elements present significant numerical challenges. The authors describe the block recursion method, an accurate, efficient method for solving the quantum circuit problem. They demonstrate this method by modeling dirty inversion layers.

Accurate restoration of DNA sequences. Progress report
The primary of this project are the development of (1) a general stochastic model for DNA sequencing errors (2) algorithms to restore the original DNA sequence and (3) statistical methods to assess the accuracy of this restoration. A secondary objective is to develop new algorithms for fragment assembly. Initially a stochastic model that assumes errors are independent and uniformly distributed will be developed. Generalizations of the basic model will be developed to account for (1) decay of accuracy along fragments, (2) variable error rates among fragments, (3) sequence dependent errors (e.g. homopolymeric, runs), and (4) strand--specific systematic errors (e.g. compressions). The emphasis of this project will be the development of a theoretical basis for determining sequence accuracy. However, new algorithms are proposed and these will be implemented as software (in the C programming language). This software will be tested using real and simulated data. It will be modular in design and will be made available for distribution to the scientific community.

Active sites environmental monitoring Program - Program Plan: Revision 2
The Active Sites Environmental Monitoring Program (ASEMP), initiated in 1989, provides early detection and performance monitoring of active low-level-waste (LLW) and transuranic (TRU) waste facilities at Oak Ridge National Laboratory (ORNL). Several changes have recently occurred in regard to the sites that are currently used for waste storage and disposal. These changes require a second set of revisions to the ASEMP program plan. This document incorporates those revisions. This program plan presents the organization and procedures for monitoring the active sites. The program plan also provides internal reporting levels to guide the evaluation of monitoring results.

The Administration of Auxiliary Services in Texas Public Universities: Analysis and Proposed Integrated Model
The problem of this study was to develop a model for the administration of auxiliary enterprises in Texas higher education as a cooperative effort of administrators and input from other sources. The purposes were to determine which administrators currently have the responsibility for the management of auxiliary services, to evaluate the correlation between the type of administrator and the concern for fiscal and student needs, to identify problems and opportunities for useful administration, and to develop a model integrating the strengths of each administrator and the implementation of new ideas to improve auxiliary enterprise management. A survey instrument consisting of three types of questions was mailed to both Vice Presidents of Fiscal Affairs and Student Affairs at all 26 four-year public institutions in Texas. Part I questions were informational, designed to determine who administers auxiliary services. Part II consisted of 20 questions on a Likert scale to obtain both opinions on the theories of the research, and specialized knowledge of the administrators. Part III was free response to solicit ideas from the administrators for the construction of the model. Paired t-tests were performed to determine knowledge strengths of the administrators. All other information was presented in frequency tables or narrative …

Advanced coal fueled industrial cogeneration gas turbine system. Final report, June 1986--April 1994
Demonstration of a direct coal-fueled gas turbine system that is environmentally, technically, and economically viable depends on the satisfactory resolution of several key issues. Solar Turbines, Incorporates technical approach to these issues was to advance a complete direct coal-fueled gas turbine system that incorporated near-term technology solutions to both historically demonstrated problem areas such as deposition, erosion, and hot end corrosion, and to the emergent environmental constraints based on NO{sub x}, SO{sub x}, and particulates. Solar`s program approach was keyed to the full commercialization of the coal-fueled cogeneration gas turbine which would occur after extended field verification demonstrations conducted by the private sector. The program was structured in three phases plus an optional fourth phase: Phase 1 -- system description; Phase 2 -- component development; Phase 3 -- prototype system verification; and Phase 4 -- field evaluation.

Advanced materials for the energy efficient production of aluminum. Final report
The Hall process has always suffered from important problems, among which is the use of consumable carbon anodes, hence, attempts had been made in the past to find an inert anode. A different approach was taken in the present research: a metal anode covered by a protective oxide film is operated so that the film is thick enough to prevent chemical attack of underlying metal, yet thin enough to allow electric current to pass without increase in cell voltage. Specimens of various candidate alloy compositions (Cu-Al, Ni-Al, Cr-Al, Fe-Cr-Al) were electrolyzed; results are promising. Areas for further research on nonconsumable anode for Hall cell are outlined.

Advances in nuclear data and all-particle transport for radiation oncology
Fast neutrons have been used to treat over 15,000 cancer patients worldwide and proton therapy is rapidly emerging as a treatment of choice for tumors around critical anatomical structures. Neutron therapy requires evaluated data to {approximately}70 MeV while proton therapy requires data to {approximately}250 MeV. Collaboration between Lawrence Livermore National Laboratory (LLNL) and the medical physics community has revealed limitations in nuclear cross section evaluations and radiation transport capabilities that have prevented neutron and proton radiation therapy centers from using Monte Carlo calculations to accurately predict dose in patients. These evaluations require energy- and angle-dependent cross sections for secondary neutrons, charged-particles and recoil nuclei. We are expanding the LLNL nuclear databases to higher energies for biologically important elements and have developed a three-dimensional, all-particle Monte Carlo radiation transport code that uses computer-assisted-tomography (CT) images as the input mesh. This code, called PEREGRINE calculates dose distributions in the human body and can be used as a tool to determine the dependence of dose on details of the evaluated nuclear data. In this paper, we will review the status of the nuclear data required for neutron and proton therapy, describe the capabilities of the PEREGRINE package, and show the effects of tissue …

An aerial radiological survey of the Fort Calhoun Nuclear Power Plant and surrounding area, Fort Calhoun, Nebraska
An aerial radiological survey was conducted over the Fort Calhoun Nuclear Power Plant in Fort Calhoun, Nebraska, during the period June 19 through June 28, 1993. The survey was conducted at an altitude of 150 feet (46 meters) over a 25-square-mile (65-square-kilometer) area centered on the power station. The purpose of the survey was to document the terrestrial gamma radiation environment of the Fort Calhoun Nuclear Power Plant and surrounding area. The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 6 and 12 microroentgens per hour and were attributed to naturally-occurring uranium, thorium, and potassium. The aerial data were compared to ground-based benchmark exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system. A previous survey was conducted on August 9 and 10, 1972, before the plant began operation. Exposure rates measured in both surveys were consistent with normal terrestrial background.

An aerial radiological survey of the Oyster Creek Nuclear Power Plant and surrounding area, Forked River, New Jersey. Date of survey: September 18--25, 1992
An aerial radiological survey was conducted over the Oyster Creek Nuclear Power Plant in Forked River, New Jersey, during the period September 18 through September 24, 1992. The survey was conducted at an altitude of 150 feet (46 meters) over a 26-square-mile (67-square-kilometer) area centered on the power station. The purpose of the survey was to document the terrestrial gamma radiation environment of the Oyster Creek Nuclear Power plant and surrounding area. The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 4 and 10 microroentgens per hour and were attributed to naturally-occurring uranium, thorium, and radioactive potassium gamma emitters. The aerial data were compared to ground-based benchmark exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system. A previous survey of the power plant was conducted in August 1969 during its initial startup phase. Exposure rates and radioactive isotopes revealed in both surveys were consistent and within normal terrestrial …

Age/Cohort Differences in Aspects of the Self-System
Age/cohort differences in several aspects of the self-system were investigated utilizing a sentence completion paradigm. Eighty-eight adults over age sixty and one hundred eight adults under age forty served as subjects. Subjects were asked to complete 30 self-referent sentence stems which were pre-structured to elicit information from the self-system. Responses were subjected to a content analysis utilizing a coding system which contained concepts used by subjects in their self-representations. Contents were coded for dimensions conceptually related to Physical Health, Autonomy, Self-Evaluation, Depression, Spirituality, and Altruism. Frequencies of codings were counted and subjected to statistical analysis for performing age group comparisons.
