Primary Coolant Pump
Circulates coolant to remove fusion heat.
- Role
- Heat removal
Primary coolant pumps circulate the fluid that removes heat from the blanket and first wall and carries it to power conversion. They are conventional but critical balance-of-plant machinery.
Common questions
What does the primary coolant pump do?
It circulates coolant through the breeder's blanket and first wall to carry away the neutron and surface heat, feeding it to the heat exchanger. It is standard high-reliability power-plant equipment.
Is coolant technology a fusion unknown?
No — the pumps and loops are conventional; the fusion-specific requirement is compatibility with the neutron environment and, on the breeder, with tritium permeation.
