Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

One of the things that not many people know is that the Navy's reactors are designed in a fail-safe (sort of) manner such that if the coolant temperature rises, the rate of fission decreases.

Heh. That's (sort of) true for BWR as well.

Both PWR's and BWR's are like that, and it's called negative void coefficent. Having a positive one is very bad, as in an exponentially accelerating nuclear reaction when the core heats up. That's what happened at Chernobyl. The core went from 1000 MW to 1000 GW in a fraction of a second, blowing everything to hell.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
