Foundation for Breakthrough Innovation

Kairos Power strongly believes that engagement and collaboration with the advanced reactor community to perform key analyses of FHR technology in parallel with rapid learning cycles is fundamental to reducing technical risk — and will ultimately enable the world’s transition to clean energy.

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.

Additional Model Data

While the gFHR data maintains key characteristics and phenomena of a KP-FHR for use in applied reactor physics methods, critical design components have been removed. Use of this data outside of benchmarking purposes will not produce realistic values.
