Radiological dose assessment of Department of Energy Pinellas Plant waste proposed for disposal at Laidlaw Environmental Services of South Carolina, Inc.

Abstract ARIES (Autonomous Robotic Inspection Experimental System) is a program for the Department of Energy (DOE) that was charged with the mission of surveying and inspecting drums containing low-level radioactive waste stored in warehouses at DOE facilities. This paper reports on the final development of the ARIES project, and focuses on the mechanical design and analysis of three mechanisms that position a camera and sensor package that sits atop a Cybermotion K3A mobile robotic platform. The ARIES project was executed through a joint effort of three parties: University of South Carolina (USC), Clemson University, and Cybermotion, Inc., of Salem, Virginia. The goal of the project was to develop an autonomous mobile robot that positions a data acquisition package (DAP) which surveys drums containing hazardous materials in Department of Energy (DOE) warehouses. The unique mechanical design of the positioning system is comprised of three distinct components: a lift mechanism, a fourbar mechanism, and a camera panning mechanism. The components are integrated in a manner that allows the DAP to be positioned from 0 to 16 feet off the ground while the robot maneuvers through aisles of drums in a warehouse. The three mechanisms, and the integration thereof, are reported in this paper.

This paper describes the current pressure protection program at Savannah River Site (SRS), a Department of Energy chemical processing and nuclear material handling facility in Aiken, South Carolina. It gives a brief description of the design requirements based on ASME, API, CGA, and ASHRAE Codes. Equipment and systems requiring pressure protection at SRS are primarily pressure vessels, steam stations, process chemical systems, refrigerant and cryogenic systems and other air or gas systems. It is understood that any pressure protection program is built on five fundamental areas of responsibility: procurement, verification, registration, inspection, and repair. This paper focuses on the existing process of facility pressure protection evaluation for code compliance followed by identification of failure scenarios and system design requirements, valve selection and sizing, and verification record generation. Improvements to this process are recognized and discussed. They include the development of a computer program to perform pressure protection evaluation and generate verification records. The software would process all applicable pressure protection calculations using improved methodologies. All relevant data required would be accessible within the program. Pressure safety relief device attributes and system parameters would be displayed. The computer program would enhance design consistency, improve quality and plant safety, and make the pressure protection verification process more efficient and cost effective.

AbstractAs part of the Superfund Innovative Technology Evaluation program, the U.S. Environmental Protection Agency evaluated the High Voltage jEnvironmental Applications, Inc. (HVEA), electron beam (E-beam) technology at the U.S. Department of Energy Savannah River Site (SRS) in Aiken, South Carolina. This technology irradiates water with a beam of high-energy electrons, causing the formation of three primary transient reactive species: aqueous electrons, hydroxyl radicals, and hydrogen radicals. Target organic compounds are either mineralized or broken down into low molecular weight organic compounds, primarily by these species. The E-beam system used for the evaluation is housed in an 8- by 48-foot trailer and is rated for a maximum flow rate of 50 gpm. During two different periods totaling 3 weeks in September and November 1994, about 70,000 gallons of SRS M-area groundwater contaminated with volatile organic compounds (VOCs) was treated with the E-beam system. E-beam treatment increased groundwater acute toxicity for fathead minnows but not for water fleas. Although several VOCs were removed, lack of decrease in toxicity appears to be due to formation of toxic by-products, including haloacetic acids and aldehydes, during E-beam treatment of groundwater. An increase in inorganic carbon and chloride concentrations was observed, in the treated groundwater indicating that some VOCs were mineralized during E-beam treatment. Formation of CO
