So, the Plans are Afoot to build a new reactor at Hinkley Point.  Reactor C would be an EPR, a new design which is, apparently, "an evolution of the PWR" and there's tons of bumf at the wiki.  The Finnish and French early adopters are having problems: some of these are to do with safety-control systems (which I'd say are non-negotiable!) and some to do with workmanship (is this a "big project tendering for the lowest bidder" problem, because it seems common?).  Would a Westinghouse AP-1000 be any better? 

I'm of the reluctant opinion that nuclear power is a necessary stopgap in our decarbonisation of energy; it's just a scale thing, really, and very much a lesser evil: I want to see the inherently-safe Generation IV designs in play until the Energy Revolution is completed (and we all have fleets of replicating windmills and space solar and fusion anna Gwendoline), and then mothballed with a "thank feck that's over," like some sort of horrid mecha we no longer need (too much Evangelion before bed) but the evolution of this kit isn't like versions of mobile phone OS.  It takes time, and a gigawatt or two of nuke power is a gigawatt or two that can be not-coal power.  Fundamentally I want to see the death of Drax and something clean to feed these leccy cars.  Scale, see.

Given that opinion, what do the great and good think?  Is Hinkley C a smart step -- safer cleaner and all that -- or just another dangerous boondoggle in a chain of boondoggles?  Would a Westinghouse AP-1000 be any better? 

Do I need to get a badger suit?  ;)

The Hyperion pocket nuclear power plant -- a sealed reactor delivered on a flatbed and buried underground -- looks to be more than hype.  I'm as surprised as anyone at that. 

"They will cost approximately $25m [£13m] each. For a community with 10,000 households, that is a very affordable $250 per home.'

[the head honcho] claims to have more than 100 firm orders, largely from the oil and electricity industries, but says the company is also targeting developing countries and isolated communities. 'It's leapfrog technology,' he said.

The company plans to set up three factories to produce 4,000 plants between 2013 and 2023. 'We already have a pipeline for 100 reactors, and we are taking our time to tool up to mass-produce this reactor."

The powers that be seem committed to nuclear power as part of the post-carbon energy mix, and this looks like an interesting contender.  The leapfrog aspect is interesting too - like mobile phones "leapfrogging" wired phones in the developing world, a neighbourhood powerplant that Just Runs without any need to lay in a national grid or a nuclear power programme is a serious deal-changer.  Sealed, unscrewupable and with no weapons-grade goodies, it looks like it might address most of the in-life objections to nukes (clearly the fuel production and processing issues remain, though I've come to the opinion that they're less bad than massive climate change; your mileage may differ).
