There is a push in the UK to design small nuclear power reactors to build in addition to a few misguided large ones. Here is an article that grasps at straws to justify the plan.

It may be faster to build 24GW of nuclear generation using small reactors than using big reactors, but it will still be slower than the renewable alternatives.

Many smaller nuclear power reactors might be cheaper to build than a few large ones, but probably not cheaper than solar or wind.

Also, they do not cure the other problems of nuclear power.

These include the pollution from the mining and refining of uranium. the problems from the waste, and the danger of having a pre-exploded nuclear weapon inside a building on your territory.

Is the real issue that the UK doesn't build its own wind turbines? I am sure it would be cheaper and easier to change that, than to build any sort of nuclear reactors.
