So solly Papa San, where go heat?
Good heavens, where's my Thermodynamic hat? Of course, the incoming water turns to steam.
Where go steam, Papa San?
The steam pipe of course!
But steam pipe valve closed, Papa San?
Oh, well, steam pressure then rises. That is, until very high, enough to open relief valve.
Ah so, where go steam now, Papa San?
Well, yes, the Torus suppression pool, where it is sub-cooled back to water.
But Papa San, what to do when big round pool filled?
Oh my good heavens, something has to give. Not in my pay grade. Sayonara.
