Nuclear bomb blast videos redux!

Tobias Buckell’s brief 2007 post of a video snippet showing a Russian weapons test described as the world’s biggest ever nuclear blast has long been the most popular post on this site for search engine traffic. And rather than kvetch about people not coming here for more high-brow entertainment (!), I’m gonna make like a Roman emperor and give out more bread and circuses… pageviews is pageviews, AMIRITE? 😉

So thanks to Wired for rounding up a bunch of video clips from assorted atomic weapons tests; there’s eight over there, if you include the rather harrowing one about the Hiroshima after-effects (which you should surely watch, if only to balance any OMGZ-awesome-big-explosionz!! vibe you get from the others). These two are my personal favourites, though – this one because the mushroom cloud formation is rather beautiful (albeit in a horrifying way):

And this one because it takes you right inside the physical brutality of the blast (not to mention reminding me of a movie about the atomic test programs that I watched as a teenager, the name and basic plot of which is long gone, but the imagery of which haunts me to this day – a Futurismic big-helper gold star to anyone who can point me in the right direction):

Aren’t you glad the prospect of nuclear war is a thing of the past? Oh, wait…

How to dismantle a nuclear bomb (before it dismantles you)

old Russian nuclear bombNo, it’s not a U2 reference; in the wake of the proposed nuclear reduction initiatives between the US and Russia, those helpful folk at the BBC have an article on how nuclear weapons are decommissioned – only the procedure they witnessed was a simulation.

The dismantlement experiment is a joint exercise between the UK and Norway – the first of its kind – and was held a few miles from Oslo.

The five-day exercise has been keenly anticipated internationally as a way of building trust between nuclear weapons states and non-nuclear weapons states.

It is designed to see if one country can verify the disarmament of another country’s nuclear weapon, but without any sensitive information about national security and weapon design being compromised.

This is one of the things that has always baffled me about these sorts of agreements: everyone saying “oh yes, we should be mutually disarming!” but then tacitly acknowledging that “actually, we’d best be keeping the technology secret, because we don’t really trust you not to build more – and if you do we’ll want to have better ones”. So much for building trust, eh?

Still, the descriptions of the procedure are kind of interesting – not so much from a technical standpoint (you don’t get a list of the wrench sizes you’ll need) but as a physical manifestation of nation-state psychology:

From the start inspectors watch, photograph, seal and tag key items. They cover entry and exit points to the disarmament chamber, sweeping all those going in and out to ensure no radioactive material is smuggled away.

“It is a very choreographed process, almost like a ballet,” says Mr Persbo. “Timings are very precise.”

The amount of fissile material in a nuclear bomb is itself classified, so a number of techniques have to be employed by the inspectors to ensure nothing is diverted when they are not able to measure it in detail themselves.

Each country’s scientists have separately designed and built their own prototype devices known as “information barriers”, which can confirm that an agreed amount of radioactive material is present in any container.

If nothing else, you’ve got the switcheroo-loophole plot mechanics for a fissile re-run of The Italian Job right there. That should make for a cheery movie… but if you want some real nuclear angst to set you up for the weekend, you can read this (PDF) report from the International Commission on Nuclear Non-proliferation and Disarmament that looks at the possibility of the old and flaky nuclear command and control infrastructures of the superpowers being hacked by terrorists in order to kick off a modern-day Ragnarok.
