Project Overview

The staff of the U.S. Nuclear Regulatory Commission (NRC) is currently engaged in review activities of the Hermes construction permit application. Kairos Power LLC, is a U.S. based company developing a fluoride salt cooled high temperature reactor (KP-FHR) using TRISO fuel in pebble form.

Plant Characteristic Description
Reactor Type Low-power test reactor to support development of Kairos Power’s fluoride salt-cooled, high-temperature reactor (KP-FHR) technology.
Containment Type Functional containment implemented principally by the high temperature TRISO particle fuel. The fuel utilizes a carbon matrix coated fuel particle, similar to that developed for high temperature gas-cooled reactors, in a pebble-based fuel element. (See SECY-18-0096 for a description of functional containment.)
Power Level 35 MWth (The test reactor will not produce electricity.)
Fuel Tri-structural Isotropic (TRISO) fuel particles embedded in a carbon matrix pebble. High Assay Low Enriched Uranium (HALEU)
