Economics of Nuclear Power. (Updated August 2022) Nuclear power is cost-competitive with other forms of electricity generation, except where there is direct access to low-cost fossil fuels. Fuel costs for nuclear plants are a minor proportion of total generating costs, though capital costs are greater than those for coal-fired plants and much ...

1. Coal Washing Plant. (1). The excavator or loader feeds raw materials to the hopper of trommel scrubber; here trommel scrubber with 2-layer screen at the end. After washing off the clay, screen three outputs: above 50mm,20-50mm, and below 20mm. Above 50mm and 20-50mm, outputs are transported to another place by belt conveyors.

The capital cost of a cleaning plant is quite depen- dent on the coal, the mining method, and site specific factors. However, a lin- ear relationship can be developed for O&M costs versus cleaning plant feed rate. Most benefits of cleaning were quantified based on the results of a re- cent study of the Tennessee Valley Au- thority (TVA) system.

In the default case, the cost per ton of clean coal would increase by 4 cents (to $1.62 per ton) if a 15-percent return on investment were assumed on these funds. The cost of coal cleaning in the default case is $1.58 per ton of clean coal.
