Safe Integration of Small Modular Nuclear Reactors into Hybrid Energy Networks

energyTestedTRL 5

Imagine a small, safe nuclear battery that doesn't just make electricity, but also heats homes and produces hydrogen. This project creates the digital blueprints and safety rules to plug these reactors into a city's power grid or a big factory. It's like creating a master manual for how to mix nuclear power with other green energy sources without any risks.

The business problem

What needed solving

Integrating nuclear reactors into hybrid energy systems is a new R&D challenge. Companies lack the tools to safely and efficiently combine SMRs with other energy sources, storage, and hydrogen production.

The solution

What was built

An open-source Modelica-based library of HES components and two specific simulators for urban district heating and industrial energy hubs.

Who can put this to work

District Heating
enterprise
Target: Urban Utility Provider

If you are a utility provider dealing with the need to decarbonize a large urban area — this project developed simulation tools and methodologies that ensure the safe integration of SMRs to provide both heat and power.

Maritime & Logistics
enterprise
Target: Port Authority / Harbour Operator

If you are a harbour operator dealing with high energy demands for industrial hubs — this project developed a specific energy hub configuration that uses SMRs to provide electricity and hydrogen for shipping and logistics.

Industrial Energy
any
Target: Heavy Industry Plant

If you are a factory owner dealing with carbon taxes and energy instability — this project developed an open-source Modelica library that helps you simulate how a hybrid nuclear system would behave before you build it.

Frequently asked

Quick answers

What is the cost or price of implementing this technology?

Based on available project data, specific pricing or implementation costs are not provided; the project focuses on providing methodologies to ensure cost-effective integration.

Is this technology ready for industrial scale?

The project focuses on the near-term deployment of SMRs in Europe targeted for the 2030s, providing the simulation tools and safety assessments needed for that scale.

What are the IP and licensing terms for the software?

The TANDEM open-source Modelica-based library is publicly available in a git repository under a slightly modified 3-clause BSD-license.

How does this fit into current energy regulations?

The project studied European energy policies and market projections to ensure the proposed hybrid energy systems align with the goal of climate-neutrality by 2050.

How do I integrate this into my existing energy system?

You can use the TANDEM open-source library and the developed simulators to model the dynamic physical behavior of your specific hybrid energy configuration.

Consortium

Who built it

The consortium is well-balanced for technology transfer, featuring 19 partners across 8 countries. With a 37% industry ratio (7 companies), the project blends academic research (2 universities, 8 research centers) with commercial application, ensuring that the simulation tools are grounded in industrial reality.
