As soon as the first mill motor is started and bypassed to the line, the drive is available to start the second mill. The same process is repeated to make the drive available for starting the third mill. All three mills can operate directly across the line, or one can remain connected to the drive for variable frequency operation if required.

Environmental Impact. One advantage uranium mining has over production methods used to retrieve fossil fuels is that plants need much less uranium to create electricity than is required if using coal, natural gas or oil. One kilogram of uranium provides the same amount of energy as about 100,000 kilos of oil or nearly 220,000 kilos of coal.
