The AI Energy Paradox
AI was built to optimize efficiency—yet it is paradoxically becoming one of the largest energy consumers on earth. Training a single LLM costs tens of GWh; each inference draws 10× the power of a conventional search. By 2030, data centers will consume 8% of global electricity. The root of this challenge is thermal—multi-phase flow heat transfer is the bottleneck at every stage of power generation, storage, and consumption. MFTEL tackles this barrier on three fronts.

SMR Advantages
Big Tech Data Center Power Demand
Multi-phase flow physics is at the heart of SMR design. Two-phase flow in helical coil steam generators, natural circulation stability, and condensation heat transfer in containment during accidents—all are core competencies of MFTEL.
MFTEL Research Activities
Validating core safety issues against strengthened technical criteria and developing technology to improve core safety during multiple-failure accidents. A long-term flagship project covering natural circulation cooling, two-phase flow instability, and accident progression analysis.
Global human resources training project for securing key design technologies for next-generation SMR safety. Training specialists in passive safety systems, helical steam generator thermal-hydraulics, and containment cooling—all SMR-specific multi-phase flow phenomena.
Characterizing the effect of noncondensable gases on condensation heat transfer in steam-air mixtures. Experimentally analyzed heat transfer degradation mechanisms by light noncondensable gas (hydrogen) and gas stratification phenomena.
Numerically evaluating thermal-hydraulic characteristics of ERVC in high-power reactors. Developed CFD-aided natural circulation flow rate estimation to quantitatively assess ERVC coolability limits.
