Only company wanting to build nuclear in the UK is EDF - all the rest pulled out so the projects got cancelled. Give it 5 years and the uk will have 3 nuclear power stations left working (Hinkney Point B, Heysham 1 and Hartlepool all due to close before 2025)
Example of short-sighted approach to energy security was the Brown/Labour sell-off of native nuclear energy capability in the late noughties.
