Strong quake and tsunami hits Japan

Ord, you're talking about Pebble Bed Reactors, right? I'm pretty sure that the Fukushima reactors are all Boiling Water Reactors (a more advanced type of Light Water Reactor). Unless you mean they should using Pebble Beds instead, with which I whole-heartedly agree.

Is that what they're calling them the 3rd-4rth generation designs ? I remember it being discussed in the Chemical Engineering periodicals I read in college (20 years ago!), but I don't recall any reactors in the U.S built on that design. The Boiling water reactors, I'd consider more of a late 50's-60's design. 2nd generation based on the Navy's reactor designs push by Hyman Rickover.
