What this contract is for

An accelerator-driven, sub-critical molten-salt nuclear system that centrally produces large quantities of tritium for fusion energy. By pairing accelerator-driven subcritical operation with molten-salt chemistry, the system offers a controllable, safety-forward pathway to produce fusion fuel, recover useful energy and convert legacy nuclear liabilities into strategic energy assets. Overview: The Accelerator-Driven Sub-Critical Molten-Salt Assembly (ADS+MSA) is a centralized nuclear facility that uses a high-power particle accelerator coupled to a liquid molten-salt system to reliably produce kilogram-scale quantities of tritium. Because the system is sub-critical, nuclear reactions only occur when driven by the accelerator, providing inherent safety and operational control. By combining proven accelerator technology with modern molten-salt chemistry, the ADS+MSA removes a major bottleneck to commercial fusion energy, recovers useful energy, and strengthens U.S. energy security and national security missions under existing Department of Energy safety frameworks rather than commercial reactor licensing. Key Advantages: Enables large-scale commercial fusion energy by providing a reliable, centralized source of tritium, eliminating the need for fusion plants to breed their own fuel and significantly reducing cost, complexity, and deployment risk. Operates in an inherently safe, sub-critical configuration in which nuclear reactions stop when the accelerator is turned off, avoiding runaway scenarios and allowing operation under DOE accelerator safety orders rather than NRC power-reactor licensing. Achieves extremely high tritium production efficiency, with tritium breeding ratios far exceeding those achievable in fusion reactor blankets, enabling kilogram-scale production wi...

How to bid on this

This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.

Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
Check the set-aside listed above and confirm your business actually qualifies for it before you spend time on a proposal. See our guide to set-asides if the category is unfamiliar.
Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
