Integrating Volume Reduction and Packaging Alternatives to Achieve Cost Savings for Low Level Waste Disposal at the Rocky Flats Environmental Technology Site
In order to reduce costs and achieve schedules for Closure of the Rocky Flats Environmental Technology Site (RFETS), the Waste Requirements Group has implemented a number of cost saving initiatives aimed at integrating waste volume reduction with the selection of compliant waste packaging methods for the disposal of RFETS low level radioactive waste (LLW). Waste Guidance Inventory and Shipping Forecasts indicate that over 200,000 m3 of low level waste will be shipped offsite between FY2002 and FY2006. Current projections indicate that the majority of this waste will be shipped offsite in an estimated 40,000 55-gallon drums, 10,000 metal and plywood boxes, and 5000 cargo containers. Currently, the projected cost for packaging, shipment, and disposal adds up to $80 million. With these waste volume and cost projections, the need for more efficient and cost effective packaging and transportation options were apparent in order to reduce costs and achieve future Site packaging a nd transportation needs. This paper presents some of the cost saving initiatives being implemented for waste packaging at the Rocky Flats Environmental Technology Site (the Site). There are many options for either volume reduction or alternative packaging. Each building and/or project may indicate different preferences and/or combinations of options.

Development of an Environmental Response Handbook for BNFL Sites
The BNFL Group of Companies owns and operates a number of nuclear licensed sites in the UK, Europe, and US. These cover fuel manufacture and reactor services; power reactors; spent fuel management; and nuclear decommissioning and clean up. To implement its environmental policy, BNFL needs to have tools and techniques that allow it to: (a) Respond appropriately to Environmental Trigger Events (ETEs), and to (b) Provide assurance that BNFL is able to manage contaminated land in the short to medium term (prior to site closure). As a consequence, over the past five years, BNFL has developed the Environmental Response Handbook (ERH). ETEs on a nuclear licensed site cover a number of scenarios: proactive action to remediate known contamination; change in behavior or location of known contamination (e.g. mobility increase); revision of permitted environmental limits on contaminants; other changes in regulatory regime; precedent set by a third party; and discovery of previously unknown contamination or new contaminating event. The main themes of the ERH are: global considerations for remediation on an operational site; detailed consideration of the application of remediation to the current ETE(s); a maintained ''toolkit'' of favored remediation techniques; and case studies and action plans In this paper the …

Controlled Containment, Radioactive Waste Management in the Netherlands
All radioactive waste produced in The Netherlands is managed by COVRA, the central organization for radioactive waste. The Netherlands forms a good example of a country with a small nuclear power program which will end in the near future. However, radioisotope production, nuclear research and other industrial activities will continue to produce radioactive waste. For the small volume, but broad spectrum of radioactive waste, including TENORM, The Netherlands has developed a management system based on the principles to isolate, to control and to monitor the waste. Long term storage is an essential element of the management system and forms a necessary step in the strategy of controlled containment that will ultimately result in final removal of the waste. Since the waste will remain retrievable for long time new technologies and new disposal options can be applied when available and feasible.

Planning for the Management and Disposition of Newly Generated TRU Waste from REDC
This paper describes the waste characteristics of newly generated transuranic waste from the Radiochemical Engineering and Development Center at the Oak Ridge National Laboratory and the basic certification structure that will be proposed by the University of Tennessee-Battelle and Bechtel Jacobs Company LLC to the Waste Isolation Pilot Plant for this waste stream. The characterization approach uses information derived from the active production operations as acceptable knowledge for the Radiochemical Engineering and Development Center transuranic waste. The characterization approach includes smear data taken from processing and waste staging hot cells, as well as analytical data on product and liquid waste streams going to liquid waste disposal. Bechtel Jacobs Company and University of Tennessee-Battelle are currently developing the elements of a Waste Isolation Pilot Plant-compliant program with a plan to be certified by the Waste Isolation Pilot Plant for shipment of newly generated transuranic waste in the next few years. The current activities include developing interface plans, program documents, and waste stream specific procedures.

The Large Synoptic Survey Telescope and Foundations for Data Exploitation of Petabyte Data Sets
The next generation of imaging surveys in astronomy, such as the Large Synoptic Survey Telescope (LSST), will require multigigapixel cameras that can process enormous amounts of data read out every few seconds. This huge increase in data throughput (compared to megapixel cameras and minute- to hour-long integrations of today's instruments) calls for a new paradigm for extracting the knowledge content. We have developed foundations for this new approach. In this project, we have studied the necessary processes for extracting information from large time-domain databases systematics. In the process, we have produced significant scientific breakthroughs by developing new methods to probe both the elusive time and spatial variations in astrophysics data sets from the SuperMACHO (Massive Compact Halo Objects) survey, the Lowell Observatory Near-Earth Object Search (LONEOS), and the Taiwanese American Occultation Survey (TAOS). This project continues to contribute to the development of the scientific foundations for future wide-field, time-domain surveys. Our algorithm and pipeline development has provided the building blocks for the development of the LSST science software system. Our database design and performance measures have helped to size and constrain LSST database design. LLNL made significant contributions to the foundations of the LSST, which has applications for large-scale imaging …

Rare kaon decays
The subject of rare and ultra-rare kaons decays is very active at this time with 8 experiments from 4 labs reporting new results recently and 6 new experiments recently approved. The physics topics under study include flavor changing neutral currents (FCNC), measurements of direct and indirect CP violation and searches for lepton flavor violation (LFV). These measurements are all characterized by very high sensitivities, studying modes with branching ratios in the 10{sup -7}--10{sup -12} range with single event sensitivities approaching 10{sup -12}. This is a region of sensitivity beyond the reach of charm and B experiment, at least for now. The development of beams with fluxes well above 1MHz of kaon decays enable these experiments. In this paper the author covers some of the important new results and the goals for the new experiments.

Development of Nuclear Magnetic Resonance Pulse Sequences and Probes to Study Biomacromolecules
The determination of the three dimensional structures at high resolution of biomolecules, such as proteins and nucleic acids, enables us to understand their function at the molecular level. At the present time, there are only two methods available for determining such structures, nuclear magnetic resonance (NMR) spectroscopy and X-ray diffraction. Compared to well-established X-ray diffraction techniques, NMR methodology is relatively new and has many areas in which improvement can still be attained. In this project, we focused on the development of new NMR probes and pulse sequences that were tailored to tackle specific problems that are not adequately addressed by current technology. Probes are the hardware that contain the radio frequency (RF) circuitry used to both excite and detect the NMR signals. Pulse sequences are composed of a series of RF pulses and delays, which are applied to the sample held within the magnetic field by the probe, so as to manipulate the nuclear spins. Typically, a probe is developed for a specific set of nuclei and types of experiments and the pulse sequences are then written to use the probe in an optimal manner. In addition, the inter-development of instrumentation and methods are determined by the specific biological question …

Technology Successes in Hanford Tank Waste Storage and Retrieval
The U. S. Department of Energy (DOE), Office of River Protection (ORP) is leading the River Protection Project (RPP), which is responsible for dispositioning approximately 204,000 cubic meters (54 million gallons) of high-level radioactive waste that has accumulated in 177 large underground tanks at the Hanford Site since 1944. The RPP is comprised of five major elements: storage of the waste, retrieval of the waste from the tanks, treatment of the waste, disposal of treated waste, and closure of the tank facilities. Approximately 3785 cubic meters (1 million gallons) of waste have leaked from the older ''single-shell tanks.'' Sixty-seven of the 147 single shell tanks are known or assumed ''leakers.'' These leaks have resulted in contaminant plumes that extend from the tank to the groundwater in a number of tank farms. Retrieval and closure of the leaking tanks complicates the ORP technical challenge because cleanup decisions must consider the impacts of past leaks along with a strategy for retrieving the waste in the tanks. Completing the RPP mission as currently planned and with currently available technologies will take several decades and tens of billions of dollars. RPP continue to pursue the benefits from deploying technologies that reduce risk to human …

''Talk To Me!'' - Lessons Learned In Communicating Risks To Tenants And Others Involved In The Department Of Energy's Reindustrialization Program
Communicating risk information is more difficult than assessing it. The latter relies on data, formulas, theorems and mathematical relationships that, with some effort, can be logically explained to another person; it's objective. Communicating risks, however, is subjective and relies on personalities, perceptions and predisposition, as well as emotions. Most notably the emotion is fear--fear of the unknown, fear of the message, the messenger, or the impact of the information on something of value to the person asking the questions. The Department of Energy's Oak Ridge Operations Office is engaged in a Reindustrialization program to lease (and most recently, to transfer) formerly used facilities to private sector entities. The facilities are located at the East Tennessee Technology Park, originally a gaseous diffusion plant operated to enrich uranium for World War II efforts and later for use as fuel in civilian nuclear reactors.

The Murmansk Initiative - RF: Acceptance Testing
The Murmansk Initiative-RF (MI) was conceived to provide the Russian Federation (RF) with the capacity to manage low-level liquid radioactive waste (LLRW) and comply with the requirements of the London Convention that prohibit ocean dumping. The trilateral project among Norway, the RF, and the United States of America (U.S.) began in 1994 and was the first to utilize exclusively Russian subcontractors to upgrade and expand an existing LLRW treatment plant on the premises of RTP Atomflot in Murmansk, Russia. The project moved quickly through the design phase. Progress during the construction phase was somewhat slower because of difficulties with acquisition of hardware, inexperience with automated instrumentation and control equipment, and unexpected design changes in the cementation unit. The project advanced into the test-operation phase, which is currently underway, in June 2001. Initial runs with liquid waste have revealed that procedures for unloading spent ion-exchange sorbents could be improved and that sludges formed during removal of alkaline-earth metals should be compacted in order for the facility to operate at its full potential. Resolution of these issues is expected within the next few months.

Linkage of Operational Needs for Spent Nuclear Fuel Disposition to Technology Development Maps
The Department of Energy is preparing spent nuclear fuel (SNF) for interim storage at the major SNF sites. At the same time, work is proceeding to analyze the requirements for disposal of the SNF in a geologic repository, currently proposed to be located at Yucca Mountain in Nevada. To assist with the placement of SNF in either interim storage or the repository, certain technologies must be developed and implemented to assure that the storage can be safely and efficiently achieved. Technology development funding is diffused through a variety of resources within the DOE complex. A tool is required to show the integration of technology development activities with each of the funding sources, show the entities performing the development work, and demonstrate how the technology development assists with the interim storage and final disposition of SNF. A series of requirements for this tool were defined and a tool developed to assist with showing the required information. The tool has taken the form of Technology Development Maps that link development information, funding sources, entities performing development activities, and the material disposition path for each SNF type. These maps will be maintained as living documents to assist with integrating development activities for the …

San Juan single-well seismic data analysis and modeling study
The authors analyze single-well seismic data from the San Juan basin in Northwest New Mexico. The consistently observable events are tube-waves: direct, reflected and multiple tube-waves can be explained by the formation properties and survey geometry except for an anomalous zone with low velocity, high amplitude and horizontal polarization. To aid the data analysis, forward modeling using a variable-grid finite-difference parallel code is performed. The numerical result confirms the identified events in the field observations.

Systematic Approach for Decommissioning Planning and Estimating
Nuclear facility decommissioning, satisfactorily completed at the lowest cost, relies on a systematic approach to the planning, estimating, and documenting the work. High quality information is needed to properly perform the planning and estimating. A systematic approach to collecting and maintaining the needed information is recommended using a knowledgebase system for information management. A systematic approach is also recommended to develop the decommissioning plan, cost estimate and schedule. A probabilistic project cost and schedule risk analysis is included as part of the planning process. The entire effort is performed by a experienced team of decommissioning planners, cost estimators, schedulers, and facility knowledgeable owner representatives. The plant data, work plans, cost and schedule are entered into a knowledgebase. This systematic approach has been used successfully for decommissioning planning and cost estimating for a commercial nuclear power plant. Elements of this approach have been used for numerous cost estimates and estimate reviews. The plan and estimate in the knowledgebase should be a living document, updated periodically, to support decommissioning fund provisioning, with the plan ready for use when the need arises.
