What the current evidence supports

Human editorial judgment · 2026-08-20

Track; not yet

Why
A genuine, DOE-recognized first-of-kind criticality milestone in under 12 months, but the demonstrated artifact produces no electricity and commercial viability hinges on unproven full-power operation and licensing 2-4 years out.
Next
Re-evaluate after the 2027 full-power Mark-1 run at INL MFC-793 with the N2 recuperated Brayton cycle (power-conversion-system testing said to be 'months away'), and watch for NRC licensing progress before treating microreactor power as procurable.
