Multiphase reactors are basically mass transfer reactors. Students have been introduced to these reactors in courses on separation processes, but in those courses they were called separation units rather than chemical reactors. Thus essentially all the reactors listed have been described and their mass balances have been derived in courses on mass transfer and separations. We now simply add chemical reactions to these separation units to describe multiphase reactors.

A good reactor to use for laboratory experiments is a batch reactor with a qiescent interface. This is particularly useful in obtaining rate data under different controlled conditions of mass transfer. A simple way of varying the mass transfer. A simple way of varying the mass transfer effect is to float various sizes of plastic balls at the liquid-liquid interface, thus controlling the area of mass transfer. Reactors in which droplets of one liquid are introduced into the other can also be used. 

Ihe function of CLEM is to transfer reactor core components and test assemblies (which may be up to 40 ft long) between the various FFTF refueling stations. The SNF is always transferred in CCPs to assure cooling of the SNF and avoid overheating the SNF. CCPs may or may not be used for other components.

The AHTR has the potential to provide a highly robust safety case because of various inherent and passive safety characteristics. Inherent safety characteristics include a low-core-power density, high-heat-capacity core, and high-temperature-margin fuel. Other inherent safety characteristics of the AHTR include atmospheric pressure operation and efficient liquid-coolant heat transfer. Reactor physics for the AHTR are similar to other graphite based, coated-particle fuel systems (GT-MHR) where negative feedback comes from the high-temperature Doppler effect within the fuel. 

In Chapter 1 it was shown which aspects of a chemical process have to be studied when it is to be developed from a laboratory synthesis to an industrial process. These include reaction rates, selectivities, mixing and mass transfer, heat evolution and heat transfer, reactor safety, waste purification, etc,. To this list we have to add scaling up. The scale-up factor from a laboratory reactor to a plant reactor is usually on the order of 10 - 10, That means that all the aspects mentioned above have to be considered as a function of the scale of operation, and that extrapolations have to be made to predict the behaviour of a process on a larger scale.
