Reliability and Redundancy Readiness

Redundant, hot-swappable design is how an early burner narrows the availability gap while its component lifetimes are still being learned.

Design for the uptime you cannot yet prove

With component lifetimes unmeasured, redundancy is the near-term lever on availability. N+1 subsystems, hot-swappable modules, and fast fault isolation let the plant ride through failures that would otherwise become outages — buying uptime before fleet hours exist.

Where redundancy applies

• Cryogenic and cooling plant for the high-field magnets
• Fuel handling and injection paths
• DEC and power-conditioning trains
• Control and protection systems

Honest limits of redundancy

Redundancy narrows the availability gap but does not by itself reach Tier III. The 30–100x shortfall against 0.99982 also requires measured lifetimes and removed failure modes. Redundancy is the first move, not the whole answer.

Redundancy is the honest near-term lever precisely because it works before lifetimes are known: N+1 subsystems and hot-swappable modules let the plant ride through faults that would otherwise become outages. But it is the first move, not the whole answer. The 30–100x shortfall against Tier III also needs measured lifetimes and removed failure modes, so redundancy narrows the gap without, on its own, closing it.
