Compilation of Requirements for Safe Handling of Fluorine and Fluorine-Containing Products of Uranium Hexafluoride Conversion

Public Law (PL) 105-204 requires the U.S. Department of Energy to develop a plan for inclusion in the fiscal year 2000 budget for conversion of the Department's stockpile of depleted uranium hexafluoride (DUF{sub 6}) to a more stable form over an extended period. The conversion process into a more stable form will produce fluorine compounds (e.g., elemental fluorine or hydrofluoric acid) that need to be handled safely. This document compiles the requirements necessary to handle these materials … more

Plant Design for the Production of DUAGG

The cost of producing DUAGG is an important consideration for any interested private firm in determining whether DUCRETE is economically viable as a material of construction in next-generation spent nuclear fuel casks. This study analyzed this project as if it was a stand-alone project. The capital cost includes engineering design, equipment costs and installation, start up, and management; the study is not intended to be a life-cycle cost analysis. The costs estimated by this study are shown i… more

Development of a waste minimization expert system prototype

The overall objective of this project is the development of a generalized advanced waste minimization applicable to waste on any site, but oriented to DOE operations. The framework for the methodology is a PC-based expert system that leads the user through a waste minimization process that will tailor the general program to their specific circumstances through interactions with the experts at their facility and the expert knowledge embodied in the shell. Under this framework, the expert system … more

Glass material oxidation and dissolution system: Converting miscellaneous fissile materials to glass

The cold war and the development of nuclear energy have resulted in significant inventories of miscellaneous fissile materials (MFMs). MFMs include (1) plutonium scrap and residue, (2) miscellaneous spent nuclear fuel (SNF), (3) certain hot cell wastes, and (4) many one-of-a-kind materials. Major concerns associated with the long-term management of these materials include: safeguards and nonproliferation issues; health, environment, and safety concerns. waste management requirements; and high s… more

Feasibility study--computerized application of the hazardous material regulations

The feasibility of developing a full expert system for transportation and packaging of hazardous and radioactive materials was initiated within the framework of three subtasks: (1) analysis of commercial packages related to regulation scanning, (2) analysis of computer languages to develop the expert system, and (3) development of expert system prototypes. The strategy to develop the latter subtask was to first,develop modules to capture the knowledge of different areas of transportation and pa… more

Expert systems for the transportation of hazardous and radioactive materials

Under the supervision of the Transportation Technologies Group which is in the Chemical Technology Division at Oak Ridge National Laboratory, an expert system prototype for the transportation and packaging of hazardous and radioactive materials has been designed and developed. The development of the expert system prototype focused on using the combination of hypermedia elements and the Visual Basic{trademark} programming language. Hypermedia technology uses software that allows the user to inte… more

Hazardous Materials Transportation Expert System (HaMTES)

The Hazardous Materials Transportation Expert System (HaMTES) was developed to provide straightforward and error-free application of hazardous materials transportation regulations. The interactive system is designed to give users access to knowledge and skills that previously could be obtained only from a highly trained and experienced expert in the hazardous materials shipping regulations. The HaMTES, Version 1.0, was based on the 1995 regulations. HaMTES, Version 2.0, includes the US regulato… more

Modeling a novel glass immobilization waste treatment process using flow

One option for control and disposal of surplus fissile materials is the Glass Material Oxidation and Dissolution System (GMODS), a process developed at ORNL for directly converting Pu-bearing material into a durable high-quality glass waste form. This paper presents a preliminary assessment of the GMODS process flowsheet using FLOW, a chemical process simulator. The simulation showed that the glass chemistry postulated ion the models has acceptable levels of risks.

Using systems analysis to improve decision making in solving mixed waste problems at the Oak Ridge National Laboratory

Systems analysis methods and tools have been developed and applied to the problem of selecting treatment technologies for mixed wastes. The approach, which is based on decision analysis, process modeling, and process simulation with a tool developed in-house, provides a one-of-a-kind resource for waste treatment alternatives evaluation and has played a key role in developing mandated treatment plans for Oak Ridge Reservation mixed waste.

Using systems analysis to improve decision making in solving mixed waste problems at the Oak Ridge National Laboratory (ORNL)

ORNL has accumulated considerable quantitites of mixed wastes, many containing hazardous and radioactive components. Finding a suitable technique for treating mixed wastes is a challenging task. The Federal Facilities Compliance Act requires ODE to provide on-site treatment plans. A method of analysis was needed for quick, easy trade-off studies and alternatives evaluations. Evaluation of ORO management of mixed waste indicated that a systems analysis, including development of automated analysi… more

Conversion of plutonium scrap and residue to boroilicate glass using the GMODS process

Plutonium scrap and residue represent major national and international concerns because (1) significant environmental, safety, and health (ES&H) problems have been identified with their storage; (2) all plutonium recovered from the black market in Europe has been from this category; (3) storage costs are high; and (4) safeguards are difficult. It is proposed to address these problems by conversion of plutonium scrap and residue to a CRACHIP (CRiticality, Aerosol, and CHemically Inert Plutonium)… more
