Nuclear reactor plants are complex systems where many types and scales of technologies must work together seamlessly. Design choices at each of those scales and for each of those technologies impact the rest of the system in terms of functionality, cost, and constructability.

For nuclear energy to contribute in the coming decades, the next generation of nuclear reactor plants need to simultaneously achieve “walkaway” safe and secure operation, extremely low construction capital costs, and dramatically shorter construction and commissioning times than currently-available plants. To attain these goals, new, innovative, enabling technologies for existing advanced reactor designs are needed. The development of these enabling technologies requires understanding the inter-relatedness of design choices. Thus, ARPA-E encourages a rethinking of how pieces of the nuclear reactor system fit together when developing these enabling technologies.

Through the MEITNER[1] (Modeling-Enhanced Innovations Trailblazing Nuclear Energy Reinvigoration) program, ARPA-E seeks to identify and develop innovative technologies to enable the advanced nuclear reactor design community to mature their designs for future commercial deployment. These enabling technologies can establish the basis for a modern, domestic supply chain supporting nuclear technology.

As provided in this FOA, ARPA-E will select multiple Awardees (Prime Recipients) to develop innovative technologies using advanced modeling and simulation (M&S) tools and by leveraging expert input to enable advanced reactor systems.[2] The MEITNER Program will establish a set of well-characterized enabling technologies where:

performance and safety have been studied with multi-physics M&S tools;key cost and performance drivers have been identified for critical development and testing;key gaps in models or data have been identified, which can be addressed through targeted experimental work;costs and construction timelines are well projected; androbust techno-economic analysis (TEA) has been performed and a clear technology-to-market (T2M) plan has been created.

MEITNER Awardees will perform key enabling technology development for nuclear reactor systems, components, and structures, moving those technologies toward commercialization. The program will not support development of fundamentally new reactor core concepts nor the design of entire reactor plants. This approach is intended to focus on identifying and developing key enabling technologies for the existing U.S. advanced reactor design community that take advantage of fields adjacent to those that are typically considered nuclear energy research and development (R&D). The MEITNER Program will use modeling and simulation and, optionally, applied science and engineering-based experimental work.

The MEITNER Program will require a system-level approach in describing and quantifying how new and innovative enabling technologies fit into a plant design to make the plant “walkaway” safe, quickly-deployable, safeguardable, cost-competitive, and commercially-viable. To facilitate such a holistic view, ARPA-E will establish a separately-funded Resource Team to work with Awardees, as described in Section 2.3 below. The Resource Team will consist of three coordinated sub-teams: a computational modeling and simulation (M&S) sub-team, a techno-economic analysis (TEA) sub-team, and a subject matter expert (SME) sub-team (see Section I.E of the FOA). Through the Resource Team, Awardees will have access to SMEs from both the nuclear and non-nuclear disciplines. These resources will allow Awardees to more accurately place their enabling technologies into the larger reactor plant context.

Awardees are encouraged to leverage DOE Office of Nuclear Energy (DOE-NE) programs, such as the GAIN (Gateway for Accelerated Innovation in Nuclear) initiative ( and the Nuclear Science User Facilities (NSUF) Network (, to perform strategic experiments–either during or after completion of the Program.
