ABSTRACT
Earlier, the processes involved when different fuels are employed in a large part determine the economic selection of the fuel. These include costs incurred from the initial handling to the disposal of residue which may include smoke, radiation, etc. Often a more expensive fuel is chosen because of its greater acceptability by the community. Typically, oil is chosen over coal, and some oils producing less smoke and sulfur compounds are often specified or legislated. Indeed, this consideration was one of the reasons for the choice of nuclear fuel.
