Over at U-Know! someone posted a link to an article in The Guardian from last November (Mini nuclear plants to power 20,000 homes). The article discusses a technology under development by Hyperion Power Generation in Los Alamos, New Mexico. It’s essentially a small nuclear reactor capable of powering tens of thousands of homes and costing a relatively modest $25m.
A quick search on google news reveals an article on Reuters as recently as this week (Hyperion Has a $100M Valuation for Mini Nuclear Power) which includes the paragraph:
Now those two articles and a reading of Hyperion’s website (mostly marketing bumpf investor relations) are the extent of my knowledge on this subject, so I don’t know enough about the specifics of their solution to offer a considered critique of the actual technology. However there are some generic criticisms of this approach to energy production that I feel are valid and worth highlighting. All the same, I’m flagging this post in advance as a “first thoughts / first impressions” thing. OK?
And on that basis… yikes!
Small enough to be transported on a ship, truck or train, Hyperion power modules are about the size of a “hot tub” — approximately 1.5 meters wide. Out of sight and safe from nefarious threats, Hyperion power modules are buried far underground and guarded by a security detail. Like a power battery, Hyperion modules have no moving parts to wear down, and are delivered factory sealed. They are never opened on site. Even if one were compromised, the material inside would not be appropriate for proliferation purposes. Further, due to the unique, yet proven science upon which this new technology is based, it is impossible for the module to go supercritical, “melt down” or create any type of emergency situation. If opened, the very small amount of fuel that is enclosed would immediately cool. The waste produced after five years of operation is approximately the size of a softball and is a good candidate for fuel recycling.
Perfect for moderately-sized projects, Hyperion produces only 25 MWe — enough to provide electricity for about 20,000 average American sized homes or its industrial equivalent. Ganged or teamed together, the modules can produce even more consistent energy for larger projects.
The Hyperion team is committed to helping make the clean and safe benefits of nuclear power — benefits that could assist in solving the worst of our planet’s problems — available in even the most remote locations. We hope you will enjoy learning about Hyperion through our web site!
“Nefarious threats”? They make it sound like they’re securing the place against attack from Dr. Evil. Or that we live in a world where the worst thing that could happen is Terry-Thomas might show up and attempt to do something dastardly. Poor copywriting aside, I believe that passage from their website, coupled with some of the claims being made in the media, should raise some serious concerns.
Thousands of little nuclear reactors encased in concrete, scattered all over the world, maintained and secured by the lowest-cost local contractors? There’s a whole bunch of things wrong with that.
First of all, this commits us to a heavily industrialised future which I’m not sure is a sensible decision (i.e. one in which uranium mining and processing is done on a scale that rivals the modern oil industry — how this squares with the claim in the Reuters piece that “nuclear power […] doesn’t release greenhouse gases” is anybody’s guess). I’m not suggesting we abandon technology or automation or electrical energy; merely that we need to scale our usage of these things back dramatically if we wish to use them sustainably. Be far smarter and more selective in the technologies we adopt or continue to use.
Secondly, the waste management issues just give me the head-staggers. It’s one thing having a few secure, essentially semi-militarised, locations where the waste is produced and stored. Even that’s problematic in my view. But to handle a massively distributed network (“available in even the most remote locations”) with a reasonable guarantee that none of the stuff ever ends up in the local reservoirs? Significantly increasing the amount of highly toxic waste we produce when there are alternatives? Future history books will view such decisions as criminally negligent… beyond reprehensible and into pure evil. Always assuming there’s going to be history books chronicling our times and crimes.
Thirdly, I’m always worried when the person selling the technology creates a huge straw man regarding security. What’s he trying to distract us from?
I’m not too worried about someone weaponising this stuff. North Korea’s already done that, and depending upon how the next few years go in Pakistan, some seriously hardline Islamists may get their hands on that technology too. Also, I’m not so sure that we can rely upon Israel to pursue a rational, evidence-based foreign policy and even the countries we view as being a relatively safe pair of hands are more than capable of rationalising a pre-emptive strike one of these days. So the “scary people with nukes” cat is very much out of the bag.
What worries me isn’t a nation state getting hold of this stuff and weaponising it, but a less organised bunch of psychos getting hold of it and poisoning wells and water-tables for several generations. See, I’m not sure exactly what part of “stealing a barbecue with your bare hands” would have prevented the September 11th hijackers doing so if it was part of their mission. For me the security risk of these things is a dedicated group of nutters — some of whom, perhaps, work for a local concrete supply company? — who don’t care about getting their hands burnt, metaphorically speaking. Unfortunately it seems there are plenty of people who’d be willing to expose themselves to a lethal dose of radiation as they steal a bunch of uranium “softballs” from one of the more remote clusters of these things.
Even if powdering the stuff and dumping it into a handful of municipal reservoirs was demonstrated to only raise the risk of childhood leukemia by 0.5% in those areas, how soon before you’ve got a bunch of ghost-towns? Ghost-cities? Millions of families won’t make a level-headed and rational assessment of the risks when the headlines scream “Radioactive Reservoir! Al Qaeda dumps uranium in Dallas water supply!”
The whole thing is fraught with the kind of “What Ifs” that just don’t enter the equation when you recommend a combination of renewable energy and a reduction in consumption.
But I’d be interested in having those “What Ifs” answered and I’ll look out for more information on this over the coming months should it start to gain credibility. Maybe this is the magic space dust we’ve been waiting for.
