INTRODUCTION Battelle Energy Alliance, LLC (BEA) Management & Operating Contractor of the U.S. Department of Energy (DOE) owned 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. This will consist of a two-step process starti...
View moreThe current MARVEL scope will consist of developing an 85kWth reactor producing more than 10 kWe of electricity in the first stage of operations. In the second stage, process heat (above 300°C) will be provided to end-users specifically for type 2 demonstrations from the list above. Additional information on the technical specifications can be found in the MARVEL factsheets.
SUBMITTAL REQUIREMENTS
INL is soliciting requests from private industry on potential tests or demonstrations, leveraging MARVEL, that would be valuable for them to conduct. Companies or other interested parties are encouraged to submit EOIs relating to any of the above-mentioned topical areas (or other topics not covered by the list). Expressions of Interest will be ranked based on their potential impact to the broader US energy landscape. Promising concepts will be invited to respond to a potential Notice of Opportunity (NO) at a later stage. The NO will contain additional information about requirements for a more detailed proposal, funding expectations, timeline, and proposal ranking metrics. Following selection, a two-step process is envisaged whereby stakeholders work with national lab staff first to ensure the viability of the test/demonstration (currently intended for Fiscal Year 2026). This is then followed by a solicitation to conduct physical test/demonstration (currently intended for Fiscal Year 2027-2028).
Interested entities are requested to provide expressions of interest (via email) by close-of business on 08/30/2025. Responses must include sufficient written information confirming the responder’s qualifications and the relevancy of their proposed scope based on the guidance in Section 2. Note that responses must be no more than 2 pages in length in PDF format. They should clearly state which of the above 6 category they fall under, which partnering institutions are included in the proposal, and what level of support (beyond the NO) is needed from INL (e.g., if the end-user or INL is expected to provide specific hardware). The content should ideally cover: the goal of the application, why it is impactful for the US nuclear industry, potential technical needs and technical specifications (e.g., quantity of energy needed, temperature range, MARVEL reactor operating conditions, test durations).
If you have questions, or need additional information, please contact Stacie Strain, Program Manager, via email at [email protected] with the subject line “Response to MARVEL Utilization EOI.” Technical questions must be submitted in writing via email. Only potentially qualified entities, as determined by BEA, will be contacted for further discussions or the release of a request for proposal for the project.
PROPRIETARY INFORMATION
Because information received in response to this EOI may be business sensitive or proprietary to the responding party, respondents are encouraged to minimize the inclusion of sensitive information to the extent possible and mark information in their responses accordingly.
Battelle Energy Alliance, LLC, the management and operating contractor for the Idaho National Laboratory, issued this Sources Sought notice to solicit Expressions of Interest regarding the Microreactor Application Research Validation and Evaluation (MARVEL) demonstration. The project seeks industry input on potential tests and experiments that leverage MARVEL as a nuclear test bed for microreactor operations and end-use applications. This initiative is categorized under NAICS 221113: Nuclear Electric Power Generation. The MARVEL reactor is designed as an 85kWth system producing over 10 kWe of electricity in its initial stage, with a second stage providing process heat above 300°C for industrial demonstrations.
The primary scope includes maturing novel nuclear technologies and demonstrating use cases such as nuclear-powered microgrids, data centers, chemical processing, and synfuel production. The platform also supports the validation of modeling codes, semi-autonomous operations, remote control paradigms, and advanced safeguards or cybersecurity techniques. The procurement is structured as a two-step process, starting with a feasibility assessment in Fiscal Year 2026 followed by physical implementation and testing scheduled for Fiscal Year 2027 through 2028.
Responses to solicitation number INL-25-012 are due by August 31, 2026, though the description requests initial submissions by August 30, 2025. Submissions must be sent to Stacie Strain in Idaho Falls, ID, and are limited to two pages in PDF format. Interested parties must specify their application category, partnering institutions, and required support levels from the laboratory. High-impact concepts identified through this notice may be invited to respond to a subsequent Notice of Opportunity. One attachment, a PDF titled INL-25-012 MARVEL-EOI_v4.pdf, was included with the original posting on June 16, 2025.
