And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
The flashes at Anonymous' link are from TRIGA pulsed reactors - a control rod is blown out of the core using an air-driven piston. The reactor goes prompt critical (greater than a dollar of reactivity inserted) and power goes way up (the one I drove went from 100W to 500MW in a few milliseconds) Then the reactor immediately shuts-down due to fuel and matrix (Zr-H) temperature increase. Fun to watch people jump when it pulses. Total power generated small due to short duration. Lots of stories of course.... The main pics do not appear to be TRIGAs, and I'm not fully sure they are reactors - could be, maybe rotating control assemblies(?) and I'd like to know type. Maybe some mil stuff or ? The blue glow is Cherenkov radiation from particles going thru the water at speeds greater than the speed of light in that media - sort of like sonic boom. Continues after shutdown - hence the blue in used fuel storage pools. Not neutrinos - they are MUCH harder to detect.
Amazing how water works as a neutrino inhibitor/shielding. Need a couple pics showing some radiation glowing away.

Those look some of the reactors I saw at the Oak Ridge National labs when I was in hi skool. Those operating had Cerenkov radiation surrounding them.

ReplyDelete...you mean that wasn't the spa...?
