How to bid on RELAP5-3D Software Licensing from the Department of Energy

What the Agency is Offering

The Department of Energy is offering a licensing opportunity for its RELAP5-3D software. This software is a sophisticated tool for simulating the behavior of nuclear power plants and other complex thermal-fluid systems. It is used for nuclear reactor design, safety analysis, and plant performance evaluation.

This is not a procurement for services or products. Instead, the government is looking for companies interested in licensing this technology to commercialize it. The software is capable of modeling various reactor types, including advanced designs, and is used by regulators for licensing purposes.

Key Dates and Deadlines

This licensing opportunity was published on April 20, 2026. The deadline for expressing interest is November 01, 2026, at 9:00 AM ET. All responses must be submitted by this time.

Who This Opportunity Suits

This opportunity is suitable for companies in the professional services category, particularly those involved in nuclear energy, engineering, or software development for complex systems. Firms specializing in advanced reactor design, safety analysis, plant performance evaluation, or research and development in the nuclear sector would find this technology relevant. It is also applicable to those interested in developing or integrating simulation tools for hybrid energy systems.
