The Availability Gate Explained

Studied burner availability of 0.86-0.995 is 30-100x more downtime than a hyperscale Tier III reference of 0.99982, so a single unit cannot be a sole source today.

The numbers, stated plainly

Availability is the fraction of time a source is producing usable power. The burner's studied availability is 0.86 to 0.995. The reference for a hyperscale, mission-critical facility — Tier III — is 0.99982. The gap is large: measured in downtime, the burner is roughly 30 to 100 times further from continuous than Tier III.

What the gap means in downtime

Tier III 0.99982 corresponds to well under an hour of downtime per year. Burner availability of 0.995 corresponds to on the order of a day-and-a-half per year, and 0.86 to weeks per year. For a continuous mission, that is the difference between negligible and mission-affecting — unless the system is designed to cover it.

The honest conclusion

• A single burner unit is not a sole Tier-III-class source today.
• Redundancy (N+1 units, storage, backup generation) closes the gap at the system level.
• Availability is expected to improve from FOAK to NOAK to BOAK, but that is a projection, not a result.

This gate is a physics-and-engineering fact about a machine that is not yet built. It is not translated into any cost or price figure. Stating it up front is what lets the redundancy architecture be designed honestly rather than around an optimistic number.

Why we lead with this number

Availability is the single figure that most often gets rounded up in resilient-power claims. Kronos states it at full candor because the entire redundancy architecture depends on it being honest. A design sized to 0.99982 that the machine cannot meet would fail in the field; a design sized to 0.86–0.995 with redundancy meets the mission. The gate is a design input, never translated into any price or cost.
