Yucca Mountain project container fabrication, closure and non-destructive evaluation development activities; Summary and viewgraphs
In this presentation, container fabrication, closure, and non-destructive evaluation (NDE) process development activities are described. All of these activities are interrelated, and will contribute to the metal barrier selection activity. The plan is to use a corrosion-resistant material in the form of a cylinder with a wall thickness of {approximately}1cm (2cm for pure copper.) The materials under consideration include the three austenitic alloys: stainless steel-304L, stainless steel-316L and alloy 825, as well as the three copper alloys: CDA 102, CDA 613, and CDA 715. This document reviews the recommended procedures and processes for fabricating, closing and evaluating each of the candidate materials. (KGD)

The Yucca Mountain Project drift scale test
The Yucca Mountain Project is currently evaluating the coupled thermal-mechanical-hydrological-chemical (TMHC) response of the potential repository host rock through an in situ thermal testing program. A drift scale test (DST) was constructed during 1997 and heaters were turned on in December 1997. The DST includes nine canister-sized containers with thirty operating heaters each located within the heated drift (HD) and fifty wing heaters located in boreholes in both ribs with a total power output of nominally 210kW. A total of 147 boreholes (combined length of 3.3 km) houses most of the over 3700 TMHC sensors connected with 201 km of cabling to a central data acquisition system. The DST is located in the Exploratory Studies Facility in a 5-m diameter drift approximately 50 m in length. Heating will last up to four years and cooling will last another four years. The rock mass surrounding the DST will experience a harsh thermal environment with rock surface temperatures expected to reach a maximum of about 200 C. This paper describes the process of designing the DST. The first 38 m of the 50-m long Heated Drift (HD) is dedicated to collection of data that will lead to a better understanding of the …

Yucca Mountain Site Characterization Project bibliography, 1992--1994. Supplement 4
Following a reorganization of the Office of Civilian Radioactive Waste Management in 1990, the Yucca Mountain Project was renamed Yucca Mountain Site Characterization Project. The title of this bibliography was also changed to Yucca Mountain Site Characterization Project Bibliography. Prior to August 5, 1988, this project was called the Nevada Nuclear Waste Storage Investigations. This bibliography contains information on this ongoing project that was added to the Department of Energy`s Energy Science and Technology Database from January 1, 1992, through December 31, 1993. The bibliography is categorized by principal project participating organization. Participant-sponsored subcontractor reports, papers, and articles are included in the sponsoring organization`s list. Another section contains information about publications on the Energy Science and Technology Database that were not sponsored by the project but have some relevance to it. Earlier information on this project can be found in the first bibliography DOE/TIC-3406, which covers 1977--1985, and its three supplements DOE/OSTI-3406(Suppl.1), DOE/OSTI-3406(Suppl.2), and DOE/OSTI-3406(Suppl.3), which cover information obtained during 1986--1987, 1988--1989, and 1990--1991, respectively. All entries in the bibliographies are searchable online on the NNW database file.

YUCCA MOUNTAIN SITE CHARACTERIZATION PROJECT EAST-WEST DRIFT SYSTEM SAFETY ANALYSIS
The purpose of this analysis is to systematically identify and evaluate hazards related to the design of the Yucca Mountain Project Exploratory Studies Facility (ESF) East-West Cross Drift. This analysis builds upon prior ESF System Safety Analyses and incorporates TS Main Drift scenarios, where applicable, into the East-West Drift scenarios. This System Safety Analysis (SSA) focuses on the personnel safety and health hazards associated with the engineered design of the East-West Drift. The analysis also evaluates other aspects of the East-West Drift, including purchased equipment (e.g., scientific mapping platform) or Systems/Structures/Components (SSCs) and out-of-tolerance conditions. In addition to recommending design mitigation features, the analysis identifies the potential need for procedures, training, or Job Safety Analyses (JSAs). The inclusion of this information in the SSA is intended to assist the organization(s) (e.g., constructor, Safety and Health, design) responsible for these aspects of the East-West Drift in evaluating personnel hazards and augment the information developed by these organizations. The SSA is an integral part of the systems engineering process, whereby safety is considered during planning, design, testing, and construction. A largely qualitative approach is used which incorporates operating experiences and recommendations from vendors, the constructor and the operating contractor. The risk assessment …

Z-Area Saltstone Disposal Facility groundwater monitoring report. First quarter 1995
The three monitoring wells at the Z-Area Saltstone Disposal Facility, ZBG 1, 1A, and 2, are sampled quarterly as part of the Savannah River Site Groundwater Monitoring Program and to comply with conditions of the facility`s Industrial Waste Permit IWP-217, issued by the South Carolina Department of Health and Environmental Control (SCDHEC). During first quarter 1995, samples from wells ZBG 1 and 2 were analyzed for selected inorganic constituents, volatile organic compounds, selected radionuclides, and other constituents. Well ZBG 1A was dry and could not be sampled. None of the wells contained constituents above SCDHEC proposed groundwater monitoring standards, final Primary Drinking Water Standards, or flagging criteria. In previous quarters, wells ZBG 1 and 2 contained slightly elevated levels of tritium, similar to the tritium levels detected before Z Area began radioactive operations.

Z-Pinch Generated X-Rays Demonstrate Indirect-Drive ICF Potential
Hohlraums (measuring 6-mm in diameter by 7-mm in height) have been heated by x-rays from a z-pinch. Over measured x-ray input powers P of 0.7 to 13 TW, the hohlraum radiation temperature T increases from {approximately}55 to {approximately}130 eV, and is in agreement with the Planckian relation P-T{sup 4}. The results suggest that indirect-drive ICF studies involving NIF relevant pulse shapes and <2-mm diameter capsules can he studied using this arrangement.

Z80 based voltage and temperature monitor for the Main Ring control crate: the CC48 card
Several years ago, there seemed to be a need to monitor the power supply voltages and temperatures in the three bay racks of the Main Ring service buildings. A few years ago, another engineer seemed to have done a preliminary design using analog voltage comparators. In late 1979, it was proposed to use a microprocessor instead of analog voltage comparators. It was dramatic that all the people at a meeting were excited about the idea and unanimously approved the project. The author can remember some of the reasons why they were so enthusiastic about the idea at the time, i.e., (1) it was new to have microprocessor based cards on the Main Ring control system, (2) programmable alarm limits were preferred to resistor dividers or potentiometers with analog voltage comparators, (3) it was the first to try the communication between a host computer and distributed intelligent cards. The author started the design on the CC48 in January, 1980 and completed in April, 1980. We had the prototype card working in July, 1980 and tested the card on the system in September, 1980. Seven CC48s of the pilot production were installed in July, 1981. We mass-produced 35 more cards and finished …

Zeolite Membranes for Gas Separations
Silicalite-1, a pure silica zeolite, was deposited on a tubular, asymmetric, {gamma}-alumina support. Single gas permeation experiments with N{sub 2}, CH{sub 4}, and CO{sub 2} were carried out on the membrane. Separation experiments for N{sub 2}/CH{sub 4} mixtures were also conducted. Single-gas permeation of H{sub 2} and separation of H{sub 2}/SF{sub 6} mixture were also carried out with the membrane. Composite membranes of silicalite and Ni-SAPO-34 were also fabricated, but no CO{sub 2}/H{sub 2} selectivity was found. It is proposed to use these membranes for methanol synthesis and separation, and for separating H{sub 2} from gasification products for use as fuel cell fuel, etc.

Zeolite thermodynamics and kinetics. Final report for June 15, 1996 to June 15, 2000 to the U.S. Department of Energy, Geosciences Research Program, Office of Basic Energy Sciences on Grant No. DE-FG02-96ER14634
This report summarizes results obtained on the thermodynamic and kinetic properties of zeolites. DOE funding supported the development of techniques of material preparation as well as experimental strategies and methods for measuring solubilities, hydration states, and rates of zeolite dissolution, precipitation, and nucleation. The hydrothermal experiments provided temperature-dependent solubility products, hydration states, and a set of standard free energies of formation for end-member Na-, K-, and Ca-clinoptilolite, mordenite, and analcime. Flow-through experimental methods were used to measure the rates of Na-clinoptilolite and analcime dissolution and precipitation as a function of reaction affinity to 250C. Finally, the experimental system was modified so that the clinoptilolite-to-analcime transformation was monitored, and its rates and mechanisms were evaluated.

D-Zero Calorimeter Multiplan
This short report explains the parameters, and their basis, of the D-Zero calorimeter multiplan spread sheet Macintosh Multiplan worksheets have been found to be a valuable asset to the D-Zero design effort. The spread sheet contains parameters (constants) and results that come from the parameters. The full effect of changes in D-Zero calorimeter parameters can be calculated quite easily with Multiplan. When a change in a parameter is made, any results that pertain to that parameter automatically change also. This report will explain how some of the unobvious results were obtained.

ZERO EMISSION POWER PLANTS USING SOLID OXIDE FUEL CELLS AND OXYGEN TRANSPORT MEMBRANES
Over 16,700 hours of operational experience was gained for the Oxygen Transport Membrane (OTM) elements of the proposed SOFC/OTM zero-emission power generation concept. It was repeatedly demonstrated that OTMs with no additional oxidation catalysts were able to completely oxidize the remaining depleted fuel in a simulated SOFC anode exhaust at an O{sub 2} flux that met initial targets. In such cases, neither residual CO nor H{sub 2} were detected to the limits of the gas chromatograph (<10 ppm). Dried OTM afterburner exhaust streams contained up to 99.5% CO{sub 2}. Oxygen flux through modified OTMs was double or even triple that of the standard OTMs used for the majority of testing purposes. Both the standard and modified membranes in laboratory-scale and demonstration-sized formats exhibited stable performance over extended periods (2300 to 3500 hours or 3 to 5 months). Reactor contaminants, were determined to negatively impact OTM performance stability. A method of preventing OTM performance degradation was developed and proven to be effective. Information concerning OTM and seal reliability over extended periods and through various chemical and thermal shocks and cycles was also obtained. These findings were used to develop several conceptual designs for pilot (10 kWe) and commercial-scale (250 kWe) SOFC/OTM …

Zero Energy Buildings: A Critical Look at the Definition; Preprint
A net zero-energy building (ZEB) is a residential or commercial building with greatly reduced energy needs through efficiency gains such that the balance of energy needs can be supplied with renewable technologies. Despite the excitement over the phrase ''zero energy'', we lack a common definition, or even a common understanding, of what it means. In this paper, we use a sample of current generation low-energy buildings to explore the concept of zero energy: what it means, why a clear and measurable definition is needed, and how we have progressed toward the ZEB goal.

Zero-Power Experiments With Boiling Core B-1, BORAX-V
Results are reported of the zero-power operation of the initial boiling core B-1 from room-temperature, atmosphenlc pressure conditions at 489 deg F and 600 psig. The core characteristics which were measured are critical mass, control rod calibrations, excess reactivity, shutdown reactivity margin, reactivity effects of various core components, reactivity effects of temperature and voids, neutron flux and power distributions, and cadmium ratios. Some development and calibration work was done on a rotating oscillator rod. It was estimated that the rated full power of 20 Mw(th) probably could not be achieved, and therefore core changes were started for core B-2, designed to achieve more available excess reactivity.

Zero-Valent Iron Permeable Reactive Barriers: A Review of Performance
This report briefly reviews issues regarding the implementation of the zero-valent iron permeable reactive barrier (PRB) technology at sites managed by the U.S. Department of Energy (DOE). Initially, the PRB technology, using zero-valent iron for the reactive media, was received with great enthusiasm, and DOE invested millions of dollars testing and implementing PRBs. Recently, a negative perception of the technology has been building. This perception is based on the failure of some deployments to satisfy goals for treatment and operating expenses. The purpose of this report, therefore, is to suggest reasons for the problems that have been encountered and to recommend whether DOE should invest in additional research and deployments. The principal conclusion of this review is that the most significant problems have been the result of insufficient characterization, which resulted in poor engineering implementation. Although there are legitimate concerns regarding the longevity of the reactive media, the ability of zero-valent iron to reduce certain chlorinated hydrocarbons and to immobilize certain metals and radionuclides is well documented. The primary problem encountered at some DOE full-scale deployments has been an inadequate assessment of site hydrology, which resulted in misapplication of the technology. The result is PRBs with higher than expected flow …

Zero Waste Machine Coolant Management Strategy at Los Alamos National Laboratory
Machine coolants are used in machining equipment including lathes, grinders, saws and drills. The purpose of coolants is to wash away machinery debris in the form of metal fines, lubricate, and disperse heat between the part and the machine tool. An effective coolant prolongs tool life and protects against part rejection, commonly due to scoring or scorching. Traditionally, coolants have a very short effective life in the machine, often times being disposed of as frequently as once per week. The cause of coolant degradation is primarily due to the effects of bacteria, which thrive in the organic rich coolant environment. Bacteria in this environment reproduce at a logarithmic rate, destroying the coolant desirable aspects and causing potential worker health risks associated with the use of biocides to control the bacteria. The strategy described in this paper has effectively controlled bacterial activity without the use of biocides, avoided disposal of a hazardous waste, and has extend ed coolant life indefinitely. The Machine Coolant Management Strategy employed a combination of filtration, heavy lubricating oil removal, and aeration, which maintained the coolant peak performance without the use of biocides. In FY96, the Laboratory generated and disposed of 19,880 kg of coolants from 9 …
