Peak Uranium? Our nuclear future might be shorter than we thought

Billet of highly-enriched uraniumWe’ve all heard of Peak Oil (even if there’s some doubt about whether we’ve heard the truth over when it’s going to actually kick in), but there’s no need to worry – nuclear power will step in to fill the gap, right? [image courtesy Wikimedia Commons]

Well, not for long, perhaps, at least according to Dr Michael Dittmar and his new analysis of the global nuclear industry:

the most worrying problem is the misconception that uranium is plentiful. The world’s nuclear plants today eat through some 65,000 tons of uranium each year. Of this, the mining industry supplies about 40,000 tons. The rest comes from secondary sources such as civilian and military stockpiles, reprocessed fuel and re-enriched uranium. “But without access to the military stocks, the civilian western uranium stocks will be exhausted by 2013, concludes Dittmar.

It’s not clear how the shortfall can be made up since nobody seems to know where the mining industry can look for more.

That means countries that rely on uranium imports such as Japan and many western countries will face uranium shortages, possibly as soon as 2013. Far from being the secure source of energy that many governments are basing their future energy needs on, nuclear power looks decidedly rickety.

But what of new technologies such as fission breeder reactors which generate fuel and nuclear fusion? Dittmar is pessimistic about fission breeders. “Their huge construction costs, their poor safety records and their inefficient performance give little reason to believe that they will ever become commercially significant,” he says.

The upswing of Dittmar’s research is that it provides a good reason for the nuclear powers of the world to continue using their military weapons-grade stock for civilian purposes… I can’t find the link, but I read somewhere recently that something like 10% of the US energy grid is powered by decommissioned warhead material already. Swords to ploughshares, indeed.

Of course, as with any matter pertaining to energy generation these days, there are disagreements as to the validity of Dittmar’s research; a commenter at the Technology review piece linked above points to this response in the Wall Street Journal:

Worries about long-term uranium supplies surface every so often; talk of a global nuclear revival fans the flames. So what’s the score?

The International Atomic Energy Agency and Nuclear Energy Agency figure there’s enough uranium to power existing plants for 100 years. Granted, there are some supply-side issues. About 40% of current uranium supplies come from stockpiles and old weapons—not from uranium mines—so new sources need to be developed soon to avoid “uranium supply shortfalls,” they say.

Nuclear power’s growth will nearly double the world’s appetite for uranium by 2030, says the IAEA/NEA “Red Book,” but there should be enough in the ground to go around…

So, once again, the problem for a layman like myself (in the absence of access to the evidence, plus the time and expertise to do the research) is deciding whose version to believe. I rather suspect this issue will increase in visibility in the coming years, so I’m going to withhold any judgement for now… though I will note that both Peak Oil and Peak Uranium are being downplayed by those non-governmental organisations whose power and influence will wane and disappear in sympathy with the availability of the resource which they manage. Cui bono, and all that.

Solar system looking more resource-rich by the day

There’s water on Mars, and there’s water on the Moon. And now there’s water out in the asteroid belt, too – if spectral analysis of the rock known as 24 Themis is to believed, that is [via SlashDot]:

Analyses of the sunlight reflected off the asteroid also show that organic compounds are widespread on the surface, he added, including polycyclic aromatic hydrocarbons, CH2 and CH3.

The new finding corroborates earlier observations of the same asteroid by astronomers Andrew S. Rivkin and Joshua Emery who also used the Infrared Telescope Facility. Over several years, Rivkin and Emery had found evidence of frozen water in single spots on 24 Themis but had not studied the asteroid as it made one entire rotation. Together, the two teams’ findings reveal that the asteroid’s entire surface is coated with frozen water, Campins says.

[…]

The scientists say these new findings support the theory that asteroids brought both water and organic compounds to the early Earth, helping lay the foundation for life on the planet.

Well, maybe, but it also supports another theory: the asteroid belt is actually the broken remains of Earth’s twin planet which was destroyed by Xenu in a fit of pique OMFG!!!1

Ahem.

The destructive rage of entirely fictional deities aside, it’s becoming clear that the necessities of life – if not life itself – are more abundant out beyond the gravity well than we thought. So maybe we should lend more credence to speculative work like that of planetary scientist Richard Greenfield Greenberg, who theorizes that not only is Europa’s ocean comprised of water, but that it may be more oxygen-rich than those of Earth, meaning there could be all sorts of weird multicellular lifeforms lurking out there waiting to be discovered.

Isn’t it high time we went out and looked?

The map is not the territory – the Arctic Circle and the cartography of conflict to come

Arctic Circle claims mapThings are heating up in the Arctic Circle – and not just because of climate change. The prospect of as-yet untapped natural resources lurking at the crown of the globe may cause a resurgence in territorial disputes, as various nations attempt to stake their claims to jurisdiction over the area.

In an effort to inform policy-makers, researchers in the UK have used specialist geographical software to create a map that lays out the potentially disputable regions in detail. Whether the map becomes a focal point for reasoned discussion or a template for military operations rooms remains to be seen.

Space video about near earth asteroid missions

Asteroids - a key step in our development of space?Last week here on Futurismic there were some great comments over the future of space seen from a resource rather than an expedition point of view. I mentioned in my post my hope that asteroids may in future be a good source of precious metals such as platinum. Today I stumbled across an example of how that may be done. Aside from the cheesy music and voiceover, this video from Space.Com shows Nasa planning of how to utilise the new Orion Moon landers to travel to Asteroids passing near to Earth’s orbit. By combining this style of approach with a few unmanned surveys of the composition of the NEO (near earth object), it may be possible to start harvesting precious metals that even a few tons would greatly increase current levels.

Is space the third option?

Out here, noone can here you scream for more resourcesIn a move that will excite many science fiction fans, a political scientist from Norway has suggested there may be a third way to solve the coming environmental problems of the21st century: Space. He posits that there are two theories for sustainable development. One, Ecologism, aims for a post industrial era of lessened use of carbon and requires a change in the way our current political and social climate works. The other is Environmentalism which aims to keep life much as it is, only using funds to develop, repair and nurture the environment. However, he thinks that by tapping into the resources offplanet, it may be able to solve the Earth’s issues. Reading the brief it seems like very much a political rather than scientific hypothesis but there’s definitely a place for space in the coming time when resources become scarce – we just have to know where to look.
