The diagram below shows how uranium is used in the production of nuclear power. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. You should write at least 150 words.

The diagram presented displays the different steps covered in order to produce nuclear power from

uranium

. At first glance, it can be observed that the process involves primarily 6 steps, where one of them can be considered cyclical. On the whole, it is not a cycle in which

uranium

is re-used as a

fuel

all over again to produce

this

energy. The process can be divided into two different stages, production and post-usage.

Firstly

,

uranium

is extracted from the earth. After that, it needs to be processed in order to obtain U-235

fuel

pellets, which are, basically,

uranium

converted and enriched.

Subsequently

is used as a

fuel

so that electricity is obtained from U-235. After a period of over 4 years, the

uranium

is spent and it is either re-processed and re-used or stored. In the first option, it is used to generate electricity again,

while

in the other option, the spent

fuel

is stored and buried in containers.
