INTRODUCTION
Battelle Energy Alliance, LLC (BEA), the Management and Operating Contractor of the U.S. Department of Energy (DOE) owned Idaho National Laboratory (INL), is inviting Expressions of Interest (EOI) from potential offerors for the design and replacement of five Primary Coolant System heat exchangers at the Advanced Test Reactor Complex
(ATR Complex). Interested parties are nuclear certified and qualified prior to submitting their EOI.
BACKGROUND
The five primary coolant system heat exchangers at the Advanced Test Reactor (ATR) require replacement due to aging. These essential U-tube, counter-current, crossflow, single-phase heat transfer (liquid-to-liquid) units facilitate the transfer of heat from the primary coolant system (PCS) to the secondary coolant system (SCS), ultimately leading to the cooling tower. Their efficient operation is critical to reactor functionality.
PROCESS
SUBMITTAL REQUIREMENTS
Interested firms should submit their expressions of interest via email to the undersigned by close of business on 09/12/2025. Submissions must include detailed information demonstrating the responder’s qualifications, addressing each criterion listed in Section 3 above.
Note that responses must be no more than 20 pages in length in PDF format. Only selected respondents, as determined by BEA, will receive an invitation to present their replacement plan.
If you have questions, or need additional information, please contact, via email to [email protected] with the subject line “Response to ATR Heat Exchanger Expression of Interest.” Technical questions must be submitted in writing via email.
Proprietary Information
Because information received in response to this EOI may be business sensitive or proprietary to the responding party, respondents must mark information in their responses accordingly.
