reliability of coal

Coal fired Plants: Pros and Cons

One of the greatest advantages of coal fired plants is reliability. Coal's ability to supply power during peak power demand either as base power or as offpeak power is greatly valued as a power plant fuel. It is with this fact that advanced pulverized coal fired power plants are designed to support the grid system in avoiding blackouts....

The Reliability of Uranium235

Unparalleled Reliability. The plants are so reliable because of the energyintensive nature of uranium. A uranium pellet's size is equivalent to the size of an eraser, but it boasts the same energy as 1,780 pounds of coal, 149 gallons of oil, or 17,000 cubic feet of natural gas. [2] Therefore, nuclear power plants only need to be refueled every 1824......
