NRC Uranium Conversion

Uranium Conversion After the uranium ore concentrate is produced at the mill (where it becomes uranium oxide or yellow cake) it is packaged in 55 gallon drums and sent to the uranium conversion plant At the conversion facility the yellow cake is processed and is then reacted with fluorine to create uranium hexafluoride (UF 6) Get Price

How to Calculate the Coal Quantity Used in a Power Plant

After considering the conversion efficiency in a power plant we require an heat input of (3600 / 33 44% ) 10765 kJ/ kw hr Coal Quantity Since coal has a heat value of 20 000 kJ/kg for producing one kw hr we require (10765 / 20000) 0 538 kg of coal This translates to (0 538 x 100 x 1 000) 53800 kg/hr (53 8 T/hr) of coal for an output of 100 MW Get Price
