[ RadSafe ] Suppression Pool Anyone?

[Rouse, Raymond Lawrence]

Exactly the Wet well being 1/2 filled with water  vs Drywell which is
Dry (inerted with a non combustible gas)

Hi Ed,

The suppression pool is the torus shaped device at the bottom of the
reactor.
You can see an image here: http://www.nucleartourist.com/type/bwr.htm

In case of a pressure (steam) build up in the drywell, the pressure can
be vented 
into the wetwell (suppression pool). The wetwell has a large volume of
water which 
acts to cool the steam. The steam released from the reactor pressure
vessel can
contain various radionuclides depending upon the amount of damage
suffered
by the fuel rods. 

This was the source of the radioactivity in the surpression pool.
