[ RadSafe ] Suppression Pool Anyone?

[Rouse, Raymond Lawrence]

No a suppression pool is also known as a Torus, it is a giant heat sink
designed to supply water to the reactor in the event of a Loss of
Coolant Accident (LOCA). If the reactor suffers a severe pipe shear
water would drain into the Torus that water can be cooled and returned
back to the reactor using various systems. It is also design to relieve
pressure from the Drywell. If the Drywell is vented to the Torus the
over pressure can be relived using cooling system designed the spray the
contents with cold water ie. Torus spray.

Here is the latest from the N.E.I. on Fukushima:

 

Authorities said much of the high-level radiation leaked from reactor 2
on
March 15 and 16, early in the accident. Abnormalities in the reactor's
suppression pool caused the radiation release, the Japan Nuclear
<http://www.nsc.go.jp/NSCenglish/index.htm>  Safety Commission said.
Radiation continues to leak from the suppression pool, the commission
said,
but the volume has dropped considerably.

 

Is the "suppression pool" the same as the spent fuel storage pool?   I
wouldn't think so.  But I've not heard the term before in reference to
BWRs.
