DESIGN TARGET · NOT MEASURED PERFORMANCE

Figures on this page are engineering design targets and reference-architecture values, not measured results from operating hardware. They state what the design is being engineered to achieve. Verified performance data will replace them as systems are built and tested. Nothing here should be relied upon as a performance warranty.

Design basis
ARCHITECTURE

Two independent loops, 2×100%

Each loop is sized for full thermal duty so a single-loop trip degrades to reduced power rather than forcing a plant trip. Loops are physically separated and independently powered.

PRIMARY SIDE

Molten fluoride salt

Activated primary salt is confined to the primary loop and the intermediate exchanger. It never enters the power island.

INTERMEDIATE

Clean secondary break

Intermediate heat exchangers place a non-activated boundary between the primary loop and power conversion, so maintenance on the energy island does not become radiological work.

SAFE STATE

Freeze plug + gravity drain

A frozen salt plug held solid by active cooling melts on loss of power, draining inventory to passively cooled tanks. No operator action, no pumped flow required.

Interfaces

Primary loop interfaces to the breeding blanket on the hot side and the intermediate exchanger on the cold side. Instrumentation reports to the supervisory layer over the plant I&C bus. Drain tank state, freeze-plug temperature, and loop ΔT are supervised continuously and are inputs to the protective logic.
