The Savannah River Site (SRS), a 803 km² U.S. Department of Energy (DOE) facility in south-western South Carolina, incorporates pollution prevention as a fundamental component of its Environmental Management System. A comprehensive pollution prevention program was implemented as part of an overall business strategy to reduce waste generation and pollution releases, minimize environmental impacts, and to reduce future waste management and pollution control costs. In fiscal years 1995 through 1997, the Site focused on implementing specific waste reduction initiatives identified while benchmarking industry best practices. These efforts resulted in greater than $25 million in documented cost avoidance. While these results have been dramatic to date, the Site is further challenged to maximize resource utilization and deploy new technologies and practices to achieve further waste reductions. The Site has elected to target a site-wide reduction of contaminated work spaces in fiscal year 1998 as the primary source reduction initiative. Over 120,900 m² of radiologically contaminated work areas (approximately 600 separate inside areas) exist at SRS. Reduction of these areas reduces future waste generation, minimizes worker exposure, and reduces surveillance and maintenance costs. This is a major focus of the Site's As Low As Reasonably Achievable (ALARA) program by reducing sources of worker exposure. The basis for this approach was demonstrated during 1997 as part of a successful Enhanced Work Planning pilot conducted at several specific contamination areas at SRS. An economic-based prioritization process was utilized to develop a model for prioritizing areas to reclaim. In the H-Canyon Separation facility, over 3,900 m² of potentially contaminated area was rolled back to a Radiation Buffer Area. The facility estimated nearly 420 m³ of low level radioactive waste will be avoided each year, and overall cost savings and productivity gains will reach approximately $1 million annually as a result of this effort. During fiscal year 1998, SRS will intensify the reclamation of contaminated work areas through implementation of the Site Rollback Plan. The economic based model was utilized to prioritize areas for reclamation based on achieving a return on investment of over 2:1. Generators have been challenged to exceed planned rollbacks through a DOE imposed Performance Based Incentive with the Site Operator. In the first quarter, over 1,580 m² of contaminated areas have been reclaimed with approximately 7,720 m² remaining to be done before the end of the fiscal year

Waste Vitrification Projects Throughout the US Initiated by SRS( )

6 editions published in 1998 in English and held by 18 WorldCat member libraries worldwide

Technologies are being developed by the U.S. Department of Energy's (DOE) Nuclear Facility sites to convert high-level, low-level, and mixed wastes to a solid stabilized waste form for permanent disposal. Vitrification is one of the most important and environmentally safest technologies being developed. The Environmental Protection Agency (EPA) has declared vitrification the best demonstrated available technology for high-level radioactive waste and produced a Handbook of Vitrification Technologies for Treatment of Hazardous and Radioactive Waste. The Defense Waste Processing Facility being tested at will soon start vitrifying the high-level waste at. The DOE Office of Technology Development has taken the position that mixed waste needs to be stabilized to the highest level reasonably possible to ensure that the resulting waste forms will meet both current and future regulatory specifications. Vitrification produces durable waste forms at volume reductions up to 97%. Large reductions in volume minimize long-term storage costs making vitrification cost effective on a life cycle basis

Isotopes of americium (Am) and curium (Cm) were produced in the past at the Savannah River Site (SRS) for research, medical, and radiological applications. These highly radioactive and valuable isotopes have been stored in an SRS reprocessing facility for a number of years. Vitrification of this solution will allow the material to be more safely stored until it is transported to the DOE Oak Ridge Reservation for use in research and medical applications. A previous paper described operation results from the Am-Cm Melter 2A pilot system, a full-scale non-radioactive pilot facility. This paper presents the results from continued testing in the Pilot Facility and also describes efforts taken to look at alternative vitrification process operations and flowsheets designed to address the problems observed during melter 2A pilot testing

The Savannah River Site (SRS) has a 40-plus year history of producing and processing tritium primarily for use in nuclear weapons. This gas is stored at high pressures in reservoirs that are manufactured and sealed through the use of special resistance welding processes. There is an interest in maintaining the quality and consistency of these welds to avoid leaks in the reservoirs. The reasons for this are the limited supply and high cost of producing tritium, the necessity of assuring nuclear safety and to promote weapon system reliability. Precisely machined 304-L and 316 stainless steel components are the materials used in the fabrication of the reservoir. This presentation will include a survey of sensors for use in resistance welding processes. The results of the application of the analog laser position sensor will be presented along with data indicating how the displacement parameter defines the weld process. Opportunities to close the control loop by taking sensor data into the weld controller will be discussed
Superconducting thermoelectric generator( )

3 editions published between 1992 and 1996 in English and held by 12 WorldCat member libraries worldwide

This invention is comprised of an apparatus and method for producing electricity from heat. The present invention is a thermoelectric generator that uses materials with substantially no electrical resistance, often called superconductors, to efficiently convert heat into electrical energy without resistive losses. Preferably, an array of superconducting elements is encased within a second material with a higher thermal conductivity than that of the superconducting material. The second material is preferably a semiconductor. Alternatively, the superconducting material can be doped on a base semiconducting material, or the superconducting material and the semiconducting material can exist as alternating, interleaved layers of waferlike materials. A temperature gradient imposed across the boundary of the two materials, establishes an electrical potential related to the magnitude of the temperature gradient. The superconducting material carries the resulting electrical current at zero resistivity, thereby eliminating resistive losses. The elimination of resistive losses significantly increases the conversion efficiency of the thermoelectric device

While the use of platinum and platinum alloys for melting glass has a history dating back hundreds of years, its use for vitrification of radioactive materials has developed only within the last few years. Platinum-rhodium alloy has recently been utilized for both the containment and heating of small quantities of actinide materials during the vitrification process. Small, platinum alloy, melter systems are planned for use at the Savannah River Site (SRS) to vitrify residual actinide materials. The primary example is the SRS program to vitrify the contents of F-canyon Tank 17.1. This tank contains the majority of americium (Am) and curium (Cm) in the DOE complex. Other actinides by be verified in the future and include uranium (U) and plutonium (Pu)

Data banks for risk assessment at the Savannah River Site( )

3 editions published between 1990 and 1992 in English and held by 11 WorldCat member libraries worldwide

One of the lessons learned from many years of risk assessment experience is that mistakes of the past are soon forgotten if no method is available to retrieve and review these events. Savannah River Site has maintained a computerized data bank system for recording, retrieving and reviewing its incident history. The system is based on a series of compilations developed primarily for risk assessment but has been found to be invaluable for many other uses such as equipment reliability, project justification, and incident investigations
