MARVEL End User Application & Utilization

The Idaho National Laboratory (INL) is seeking an Expression of Interest (EOI) from industry providers to suggest potential tests and experiments leveraging the Microreactor Application Research Validation and Evaluation (MARVEL) demonstration. The MARVEL will be an operational microreactor and is expected to serve as a nuclear test bed to demonstrate microreactor operations and end-use applications. The project aims to provide a platform for the private sector to mature novel nuclear technologies and demonstrate innovative new use cases for microreactors. Some potential applications of the MARVEL reactor include: • Demonstrating novel nuclear-generated electricity applications • Demonstrating novel nuclear heat applications • Requesting data access • Operating the reactor in specific modes to validate models • Deploying advanced instrumentation and control paradigm to nuclear reactors • Demonstrating novel safeguards and security paradigms for nuclear technology Interested entities are requested to provide expressions of interest via email by close-of-business on 08/30/2025, with responses limited to 2 pages in PDF format.
