Developing Smaller, Safer, and More Cost-Effective Sodium Fast Reactors for Flexible Power Grids

energyPrototypeTRL 3

Imagine a giant power plant shrunk down into a modular kit that is easier to build and move. It uses a special liquid metal instead of water to keep things cool and safe. By using AI to spot problems early, it works like a smart home system for a nuclear reactor, making it cheaper and more reliable for the electrical grid.

The business problem

What needed solving

Traditional Gen IV nuclear plants are too large and expensive for the needs of many European countries. There is a lack of flexible, small-scale reactor options that can integrate easily into modern electrical grids.

The solution

What was built

A design for a Small Modular Reactor (SMR) version of the ESFR and AI-based monitoring tools for bubble detection in steam generators.

If you are a maintenance provider dealing with undetected leaks in steam generators — this project developed AI-based monitoring to identify and characterize bubbles for early fault detection.

Frequently asked

Quick answers

How does this project reduce the cost of nuclear power?

It focuses on simplifying the design and reducing the reactor size to create a Small Modular Reactor (SMR), which enables modularization and standardization to lower expenses.

Is this technology ready for industrial scale?

The project is currently in the design and experimental phase, moving from a 3600 MWth concept toward a smaller, more flexible SMR version.

What is the IP or licensing status of the developed technologies?

Based on available project data, the project focuses on research and experimental data production; specific licensing terms are not mentioned.

How does the project handle safety regulations?

The project maintains close interactions with EU safety regulator experts to review and recommend the proposed technical solutions.

What is the timeline for implementation?

The project period runs from 2022-10-01 to 2026-09-30, focusing on design and experimental qualification.

Consortium

Who built it

The consortium is heavily weighted toward research and academia, with 8 universities and 5 research centers out of 16 partners. Industrial participation is low at 12% (2 companies), and there are no SMEs involved, suggesting the project is currently focused on high-level technical validation rather than immediate commercialization.
