Nuclear plants are essentially identical levels of ugly to coal: from the outside both are concrete cuboids with cooling towers.

Aesthetics are not a reason either way, or the UK wouldn't have had brutalism.

Actual reason is that nuclear is expensive, while wind is much cheaper even after adding costs for storage etc.

Also that the UK can't cross-subsidise the power plants from the military because they no longer have a big enough military to justify the nuclear weapons they already have, let alone a big enough militarily to justify the capability to breed more plutonium.
