Available in PDF, EPUB and Kindle. Book excerpt: Dynamic models to simulate the performance of off-gas treatment and control systems for the High Level Waste (HLW) and Low Activity Waste (LAW) melters in the proposed Waste Treatment Plant at the Hanford Site have been developed using Aspen Custom Modeler(TM). The models are designed to give accurate pressure drops through the off-gas equipment and to show the dynamic behavior of gas pressure and flow during startup, normal operation, steam surges, and off-normal operation such as fan failures, and to evaluate the performance of proposed control strategies. This paper describes these models and presents some simulation results.

This book was released on 1996 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several key operating variables affecting off-gas flammability in a slurry-fed radioactive waste glass melter are discussed, and the methods used to prevent potential off-gas flammability are presented. Two models have played a central role in developing such methods. The first model attempts to describe the chemical events occurring during the calcining and melting steps using a multistage thermodynamic equilibrium approach, and it calculates the compositions of glass and calcine gases. Volatile feed components and calcine gases are fed to the second model which then predicts the process dynamics of the entire melter off-gas system including off-gas flammability under both steady state and various transient operating conditions. Results of recent simulation runs are also compared with available data.

Book excerpt: The objective of this work was to develop predictive models to assess offgas flammability for a low activity radioactive waste melter. The models had to be comprehensive enough to explicitly describe the effects of key melter operating variables such as total organic carbon in the feed, melter air purge and vapor space temperature. Once validated against pilot melter data, these models were used to simulate a series of safety scenarios involving over-batching of sugar, used as a reducing agent, and off-gas surges. The overall scope of the work was broken down into two parts, each focusing on a physically distinct region in the melter.

This book was released on 1995 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Idaho National Engineering Laboratory Advanced Mixed Waste Treatment Project sponsored a plasma are melter technical design review meeting to evaluate high-temperature melter system configurations for processing heterogeneous alpha-contaminated low-level radioactive waste (ALLW). Thermal processing experts representing Department of Energy contractors, the Environmental Protection Agency, and private sector companies participated in the review. The participants discussed issues and evaluated alternative configurations for three areas of the melter system design: plasma torch melters and graphite arc melters, offgas treatment options, and overall system configuration considerations. The Technical Advisory Committee for the review concluded that graphite arc melters are preferred over plasma torch melters for processing ALLW. Initiating involvement of stakeholders was considered essential at this stage of the design. For the offgas treatment system, the advisory committee raised the question whether to a use wet-dry or a dry-wet system. The committee recommended that the waste stream characterization, feed preparation, and the control system are essential design tasks for the high-temperature melter treatment system. The participants strongly recommended that a complete melter treatment system be assembled to conduct tests with nonradioactive surrogate waste material. A nonradioactive test bed would allow for inexpensive design and operational changes prior to assembling a system for radioactive waste treatment operations.
