What the loop has to do
FUNCTION 01
Move blanket heat, safely
Two independent salt loops carry heat out of the breeding blanket. Each leg is sized for full duty so a single-loop trip never forces a plant trip.
565°C
Loop temp
FUNCTION 02
Keep activated salt contained
Intermediate exchangers put a clean break between activated primary salt and the secondary side, so the power island never sees activated inventory.
2×100%
Redundancy
FUNCTION 03
Fail into a safe state
Freeze plugs and gravity drain tanks put the salt somewhere passively safe on loss of power — no operator action, no pumps required.

The coolant loop is supervised by the same Plant Intelligence layer that runs the rest of the balance of plant.
