What are the potential challenges to the UK's supply of nuclear fuel?

Raw uranium ore

The UK imports the uranium it needs to fuel its nuclear power stations. As with any imported fuel, this makes supply subject to any price fluctuations in the global market and exposed to geopolitical disturbances in the countries from which the UK imports. However uranium is sourced from a range of countries, including many which are not major suppliers of other fuels such as oil and gas. These include Canada and Australia which account for about half the world's known reserves of useable uranium.

In addition, while the price of uranium can fluctuate, fuel accounts for a relatively low proportion of the cost of electricity generated by nuclear power. As a result fluctuations in the price of uranium do not lead to major volatility in the cost of electricity generated by the power stations.
