ARPA-E to award up to $35M to develop tools to transform operations and maintenance of advanced nuclear reactors

The Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E) announced up to $35 million in new funding for the development of tools and systems that will enable reduced expense and increased flexibility in the operation and maintenance at nuclear power plants.

ARPA-E’s Generating Electricity Managed by Intelligent Nuclear Assets (GEMINA) aims to develop digital twin technology for advanced nuclear reactors and transform operations and maintenance (O&M) systems in the next generation of nuclear power plants. ARPA-E is looking for interdisciplinary teams to develop digital twins, or a similar technology, for an advanced reactor design as the foundation of their O&M strategy.

Performers will design tools that introduce greater flexibility in reactor systems, increased autonomy in operations, and faster design iteration. The goal is to create a 10x reduction in O&M costs at advanced reactor power plants, thereby improving their economic competitiveness.

To accomplish this, teams will apply diverse technologies that are driving efficiencies in other industries, such as artificial intelligence (AI), advanced control systems, predictive maintenance, and model-based fault detection.

Projects will focus on O&M solutions for the reactor core, balance of plant (BOP), or entire reactor plant system (including both the reactor core and BOP). Because advanced reactors are still in design phase, with no physical units operating, teams working on core operations will also develop cyber-physical systems that simulate advanced reactor core operating dynamics using a combination of non-nuclear experimental facilities (e.g., test or flow loops) and software. Teams will use these systems as the “real asset,” a surrogate to test their digital twin platforms.

Background. Many US nuclear reactors are shutting down prematurely. Eight have closed in the last six years; 10 more are scheduled to be decommissioned by 2025. The reason is that although nuclear power is considered by many to be necessary to achieve a zero-carbon grid, nuclear power plants are comparatively cost-intensive in some markets.

Many industries are employing AI, advanced data analytics, distributed computing, powerful physics simulation tools, and other breakthroughs to advance autonomous, efficient, and low-cost O&M in their processes.

O&M is approximately 80% of a reactor’s total generating cost. So far, the nuclear energy industry has not fully explored or applied these innovations, resulting in a profound need for the design of effective and low-cost advanced reactor O&M procedures. There is tremendous opportunity for innovation in advanced reactors, since learnings gained now can provide feedback into the designs, laying the groundwork for optimal O&M.

GEMINA sets the stage for a future where advanced reactors operate with a staffing plan and fixed O&M costs more akin to those of a combined cycle natural gas plant than those of the legacy light-water reactor fleet.

The program goal is to reduce fixed O&M costs from ~13 $/MWh in the current fleet to ~2 $/MWh in the advanced fleet.



Good essential O & M objectives but the same level of cost reduction is required for initial NPPs construction cost to make nuclear energy more competitive with REs?


REs and fossil should be regulated until they are as safe as nuclear (they are vastly more dangerous).  THAT will fix the cost disparity.


Not so sure SAEP! Curent trend is going the other way?


Yes, AlzHarvey.  Wind, solar, hydro and fossil backups are WAY under-regulated compared to nuclear based on threat to life and health.  Fix that cost mis-allocation and your power will be either 80% nuclear or all your dams will have nobody living in the threat area downstream... and that's one hell of a lot of area.


Agree with you that bio-fossil power plants should be better regulated and progressively taxed for pollution and GHGs produced until they become financially unproductive. This would progressively favour 24/7 REs and V2G systems and NPPs. .
