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

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.
