A Review of Criticality Accidents

A Review of Criticality Accidents (3.7 MB pdf) Do you like reading comp.risks, or CVR transcripts from famous plane crashes? Then you may enjoy this technical analysis of 60 accidents where improper handling of fissile materials led to unexpected critical mass. All the famous names are here - Oak Ridge, Los Alamos, the Argonne National Lab - as well as the famous players: the Demon Core that claimed two lives in separate accidents, and later became the heart of the Bikini atoll ABLE nuclear test; Harry Dahglian; Louis Slotin; and even a cameo by Richard Feynman, who comments on the Dragon experiment in a footnote. Watch for the telltale signs of prompt critical - the blue glow, the flash of light, the wave of heat - and look up Roentgen Equivalent Man, and tuballoy in the comprehensive glossary at the end. I can't be the only one who likes this stuff, can I? (Via AskMe.)

Nuclear waste UK rail hazard?

A timetable of UK trains carrying nuclear waste. (PDF file). The related Greenpeace UK article. UK nuclear waste train route graphic. Mirror tabloid hack plants fake bomb on nuclear waste train. "The gate was open, there were no security guards. I walked up to the train and planted my bomb". The Guardian's take on the story.

No Accidents in Over 30,000 Years!

Pro-forma nuclear safety is harder than ever to sell. There's ass-kissing to the sci-fi community (.pdf, download it), the instructional video (warning, boring .wmv, > 12 mins long). But... The design lifetimes of Yucca Mountain and the Waste Isolation Pilot Plant won't protect future generations from groundwater absorbing transuranic waste (Pu239 and like toxins, deadly when ingested for 240,000 years). Do you have this stuff in your back yard today, and how will it get there safely? On top of that, the capacity problem, which looks intractable as long as we keep relicensing plants. If I didn't know better, I assume the only way the government could succeed in getting this done would be to hoodwink us.

Live near one of these 10 nuclear power plants? They either have cracks in their control rod nozzles or are particularly "vulnerable" to cracking. An inspection at Ohio's Davis-Besse plant led to the completely unexpected discovery of "the most extensive corrosion ever found on top of an American nuclear plant reactor". Radioactive boric acid leaked out of the cracks and came within a half-inch of burning a hole through the steel containment dome. NRC officials say this kind of corrosion "was never considered a credible type of concern," but nuclear safety groups have been warning for years that NRC inaction on this issue was endangering the public.

Of the three ways in which the A-Bomb can hurt you, RADIATION IS THE LEAST HARMFUL. An earlier post reminded me of this pamphlet from the Massachusetts Civil Defense Agency. Not as much fun as Duck & Cover, to be sure, but terribly earnest. Remember: Stay down for at least one minute.
