Nuclear Reactors
Pressurized Water Reactor - Most common
In the pressurized water reactor, the water which flows through the reactor
core is isolated from the turbine.
The water which passes over the reactor core to act as moderator and
coolant does not flow to the turbine, but is contained in a pressurized
primary loop. The primary loop water produces steam in the secondary
loop which drives the turbine. The obvious advantage to this is that a fuel
leak in the core would not pass any radioactive contaminants to the
turbine

the idea of using explosive charges to compress a sphere of plutonium very
rapidly to a density sufficient to make it go critical and produce a nuclear
explosion.

Ivy Mike was the first H Bomb test, it was exploded at 7.15 am local time on November 1st 1952. The mushroom cloud was 8 miles across
and 27 miles high. The canopy was 100 miles wide. Radioactive mud fell out of the sky followed by heavy rain. 80 million tons of earth
was vaporised. Mike was the first ever megaton yeild explosion. I think that this footage is available in the "TRINITY AND BEYOND™
(The Atomic Bomb Movie)" movie (http://www.atomcentral.com/trinity.html)
