The UK has a few nuclear projects in progress (mostly done by foreign companies, including the French state owned EDF and even a Chinese company at some point), and a domestic small modular reactor program in research.

There have been delays and budget overruns (nothing unexpected really) at Hinkley Point C (an EPR build by EDF; and where the cleanup and decomissioning costs are explicitly included in the overall costs of the project and the electricity price reflects that) and that had stirred some debate, but i don't think anyone is still complaining about it.
