# ORNL Advances Nuclear Reactor Modeling

Oak Ridge National Laboratory is applying modeling, simulation, and experimental validation to support power uprates at existing U.S. reactors and the design and licensing of advanced reactors. The work involves Kairos Power and Antares Nuclear, but the announcement identifies no solicitation, contract award, funding amount, or procurement deadline. For contractors and reactor developers, it signals technical collaboration and independent design-assessment activity rather than a currently advertised procurement opportunity.

- ORNL’s work connects analytical modeling with experimental validation, relevant to organizations providing reactor engineering, simulation, testing, and design-assessment capabilities.
- The involvement of Kairos Power and Antares Nuclear points to activity around advanced-reactor design and licensing; interested firms can assess whether their technical capabilities complement this work.
- Because no procurement action or deadline is announced, businesses should treat this as market intelligence, not an open solicitation.
