The fuel type for UK nuclear electricity generation is Uranium.

Total simultaneous maximum load (total peak demand) met in 2013 was 51,811 MW in Great Britain – (Northern Ireland is excluded because their network is attached to the Irish Grid). [1]

Table 1 shows the current operating plants alongside their percentage of the total peak GB demand mentioned above. We do not have any mothballed UK-based nuclear generation.
