Data PHysics: IGNITIUM: A Modular Liquid-Metal Thermo-Hydraulic Micro-Reactor & Direct-to-Chip Power Architecture for Hyperscale AGI Clusters

This paper presents the formal specification of Ignitium, a modular SMR/micro-fusion power architecture designed for direct integration with AGI hyperscale clusters. We formulate a two-phase liquid-metal thermo-hydraulic cooling loop governed by a non-linear heat restitution operator $\Phi(T)$. By coupling power dynamics directly to mCDU/GPU buses, the framework eliminates standard transformation losses. SMT Z3 model checking confirms zero-latency NCCL interconnect synchronization under extreme workload transients.
