With current commercial solarcell efficiency (about 10%) it would make for around 300 km^2 of solarcells to cover the need here in Denmark so that would be around 10 times more for UK. Any house roof could be used for local supply too.

You still need to dispose of thousands of tons of reactor core etc that is radioactive when the reactor is burned out. At least it shouldnt be highly radioactive but still needs to be contained for many years.

There are some advanced Fission reactor designs being tested and one is using Thorium for fuel which is very good as there is not that much Uranium to cover all our needs for very long, while there are loads of Thorium just waiting to be used. If we wanted to move away from fossil fuels quickly then that is certainly a way.
