    there is also the "pebble reactor" design, though i'm not sure why the german stopped their research on that concept, does anyone know?

    generating electricity from nuclear sources can be done, look a the german record, or french, british... the question is, what level of safety can be afforded, for extreme situations? ideally the reactor vessel would sit inside another vessel and another...but, the expense of building the ultimately safe reactor prohibits its construction. example, here in the midwest, the original specification for the wall of the containment building was to withstand a telephone pole impact driven at 200 mph, in case of tornado. the expense of building such a structure was so high, the spec' was dropped to a 2x4 driven at 25 mph...

    You can see the two prototype "aircraft" nuclear engines in the parking lot at EBR 1, near Arco Idaho. And scratch your head at how they were going to fit inside an airplane.

    Actually, for those who enjoy old nerdy things, a stop at EBR 1 ("The Worlds First Nuclear Power Plant") is pretty cool, if you're driving through that part of the world. It's one of those "self-guided" tours where you can wander all around with little or nothing "off limits." You can play with the waldos in the hot cell, and poke around in the control room and the reactor room. (The reactor is filled with concrete.)

    The big problem seems to be maintaining the eutectic point as the fuel decays. I think this type reactor with todays technology is something well worth considering as control systems are more than capable of handing the required doping and bleed to maintain a mixture to support the eutectic point.

    I'm actaully a big FBR (Fast Breeder) fan. Back in the days when we were building power plants we knew we would never be able to permit an FBR in America. Ho hum.
