Shutdown of old nuke reactors just means you can rebuild a newer, higher efficiency one.
Unless... you can't tear down and build over a reactor due to fallout of the debris.
Anyone know?
The Brits can always buy juice from the French, too. The French love their nuke reactors.
I also don't think the Brits get much oil from the middle east. I bet most of their crude comes from the Baltic Sea platforms, and the rest from Russia. I think most middle east oil goes to Africa, Australia and Asia.
We get most of our foreign oil from Canada, Mexico and South America. Dragging it all the way from the middle east is an energy-expensive proposition.
It is a piece by piece dismantling and cleanup process (ex-Navy nuc here, and went through one submarine decommissioning). If the plant is shut down for good, the nuclear fuel has to be removed and taken away, and any high-level spent fuel waste has to be taken away too if there was some on site. In the US this is either/or kept in a swimming pool (blue glowing metal boxes in the water) and/or a concrete armored "dry cask".
Then, the low-level radioactive waste is taken apart and buried somewhere, that's stuff like piping and valves that carried radioactive materials, and a whole bunch of other stuff that doesn't have much radioactivity in it.
There's no technical reason why you couldn't put another nuclear power plant up on the same site, but I'm not aware of that ever being done anywhere. If nothing else the useful life of civilian power reactors is on the order of 30-40 years+, and the technology has improved so much since the retiring ones were built that it doesn't make much sense to keep re-using the same old equipment (I'm guessing) even if you could put another brand new reactor in the containment building where the old one used to be.
