Private equity attempting to capture profits. Much harder to do with renewables.

I don't think anyone would ever describe nuclear energy as cheap nor quick

There is currently an absolutely massive buildout of offshore wind atm, (dogger bank a/b , Sofia, east Anglia 3, inch cape, hornsea 3) and solar to a lessor degree. Its just the right media like nuclear as a solution so its talked about more than action taken

China has long term planning so they were happy to give the UK cheap loan deals to build nuclear plants to create work for the Chinese nuclear industry. Then the US started doing an Iron Curtain against China, so to suck up to both the US and China the UK had to buy out all the planned Chinese-partnered nuclear plants. To avoid looking like losers UK politicians insist on trying to go through with building them without China at crippling expense while trying to pretend like it's not a disaster.

You get a lot more energy for little resources, ignoring the upfront cost. Also the other comment

You use these things called "power lines" which make it easy to send electrical energy to different places
