Question 21

The energy released per kilogram of nuclear fuel in a fission reaction is $GJ540\ 000\text{ GJ}$ .

The energy released per kilogram of fuel in burning wood biomass is $GJ0.018\text{ GJ}$ .

Calculate the ratio of the energy released in fission compared with the energy released in burning wood biomass.

Use the equation:

\text{ratio} = \frac{\text{energy released from fission}}{\text{energy released by burning wood biomass}}
