Generic FHR Core Model

Kairos Power is leveraging the latest computational tools and advancements of highly efficient and scalable clusters to develop the multi-scale and multiphysics modeling of a pebble-bed reactor core with a high degree of fidelity.

The generic FHR core model (gFHR) functions as a benchmark for core designers, methods developers, safety analysts, and researchers to better understand the physics behavior of a KP-FHR core.
