Detailed descriptions of the practical aspects of atomizer performance, plant design, and operation for powder productionthrough atomization of liquid metals have been given by Yule and Dunkley... 

Note that at this level of description, a detailed plant design is not needed. It will eventually follow from the specific application for which the plant may be needed. 

Often, however, the information available is so indefinite that the search is hopeless from the beginning. The folklore that rheumatism can be cured by infusion of rheumatism root or rheumatism weed suggests the identification of this herb with a view to further investigation. Clute (3) has listed all such vernacular descriptive plant designations. Rheumatism root may be Chelone glabra (Scrophulariaceae), Chimaphila maculata (Ericaceae), Apocynum canna-binum (Apocynaceae), Jeffersonia diphylla (Berberidaoeae), or e en Dioscorea... 

Plant design is an active part of the total lifetime of all chemical processes. The birth to death sequence of a chemical plant is characterized by the level of detail of the plant description required at each design step. Early death of a proposed process can occur at any step before it has been built and produces a product. Only a small fraction of the initial proposals survive beyond the second step. Design continues as the process is modified to keep the product profitable in the face of all competition. The stages of a process proposal can be described as follows ... 

The major source of radioactive waste is likely to be the separation plants designed to treat solid fuel elements and to separate and purify uranium and plutonium from the fission products. Detailed descriptions of such plants are given in reference (Rl). 

The design description is focused on the Nuclear Island portion of the plant with the interfaces with the remainder of the plant (hereafter referred to as the Energy Conversion Area) and a standard site identified. The Nuclear Island is considered to be that portion of the plant that has within its boundaries the standard reactor modules and "safety-related" (as defined in Section 3.2) buildings, structures, systems and components dedicated to assuring reactor... 

Reactive distillation occurs in multiphase fluid systems, with an important role of the interfacial transport phenomena. It is an inherently multicomponent process with much more complexity than similar binary processes. Multi-component thermodynamic and diffusional coupling in the phases and at the interface is accompanied by complex hydrodynamics and chemical reactions [4, 42, 43]. As a consequence, an adequate process description has to be based on specially developed mathematical models. However, sophisticated RD models are hardly applicable for plant design, model-based control and online process optimization. For such cases, a reasonable model reduction should be applied [44],...

The chapter begins with a description of reference processes that are currently used industrially for hydrogen production and power generation from natural gas and coal. Alternative plant designs that employ membranes are discussed next. Only oxygen and hydrogen separation membranes are... 

An aspect of plant design and operation that is apparent from the above description is that the atmospheric leach section of the EPAL configuration can be used as a JAL plant, simply by piping limonite to feed the Pre-leach and adding saprolite directly to the atmospheric leach tanks. 

Design, materials of construction, fabrication methods, inspection requirements, shipment and installation, operating conditions, and inservice surveillance are all components of a program to assure reactor vessel integrity for the plant design lifetime. A complete description of the reactor vessel design is given in CESSAR-DC, Section 5.3. 

The System 80+ Standard Design incorporates pressurizer equipment that is different from current operating plant designs. For example, the Safety Depressurization System (SDS) performs rapid venting and depressurization of the Reactor Coolant System (RCS) when the Auxiliary Spray System is not available (see CESSAR-DC, Section 6.7.1.1 for a description of the SDS). Reliable pressurizer level indication is provided in the Nuplex 80+ Advanced Control Complex consistent with the guidance given in NUREG-0737.
