Good question, scale could be the problem. Pulling a few tens of megawatts from the enviroment for a wind farm sized liquid air plant isn't too difficult. Pulling a couple of gigawatts for a nuke is another matter.
I guess you could offset having to take the heat from the enviroment by pumping the heat generated (when you compress the air) into the ground and drawing it back later. That techonology exists as interseasonal heat stores.
Many would question that statement as pumps are often inside the boiler casing these days.
So what do you classify as the boiler? Just the actual heat exchanger?
Even so you're not comparing like for like. And a modern condensing boiler must have saved you a fortune in gas bills over a back boiler type - which was about the most inefficient around.

I would have thought that there would be more than enough waste heat from a nuclear power plant.
It's as much part of the boiler as a starter motor is part of a car engine.
I removed the back boiler immediately on moving in and I did say earlier that I deliberately didn't choose a condensing boiler. They are more expensive to buy and are notorious for having a much shorter life.

True as it'll be going full chat 24/7 ... So not only do you have 2 GW base load you also have 2 GW dispatchable. Why is that ringing a thermodynamic alarm bell?
Looking at the Wiki link Chris Hogg has given, a pilot plant is only achieving 15% efficiency, with a possible, maybe, sometime in the future, 60% efficiency, so I don't think we have invented perpetual motion yet.
Interesting that they have to extract CO2, to prevent it freezing in storage. In the long term, it might even extract more CO2 from the atmosphere than the concrete for the power station created.
Reporting in Lefty News, as well.
You'll have to define what you consider part of the boiler, then. And car engine, come to that.
But use less gas? You need to consider the overall costs of the system for a like for like performance.
Nope.Cheaper than nuclear too.
You've been taken in by all the hype. Have a read of this:
Unless of course you have a subsidy deal that means you can always sell at the peak market price whenever you have capacity available, and the grid is compelled to just suck it up by pushing other generators off.
;-)
However if the pump is in the same case as the boiler (e.g. system / combi) then what people used to call a fault with the pump or the heating system they now think of as a boiler fault.
Years ago perhaps - can't see why a modern condensor should be any less reliable than a similarly integrated and controlled conventional boiler.
I *like* Lefty News. I just apply the same sceptic filter that I do to the Mail or Torygraph.
From the article you provided a link to:
'Nuclear power, offshore wind and solar energy are all comparably inexpensive generators, at roughly ?125 per MW/h.'
And Harry keeps telling us how expensive nuclear power is!
