Our most loyal readers know that we closely follow technological advancements in nuclear energy at Media24.fr, especially regarding Small Modular Reactors (SMRs).
One of our favorite players in this field, the Franco-Italian company newcleo, has confirmed Europe’s reliance on its expertise through a €36 million contract secured under the ALFRED program for its subsidiary S.R.S. (Servizi di Ricerche e Sviluppo).
The ALFRRED project aims to build several experimental facilities in Romania to test quick lead-cooled reactors technology, a fourth-generation sector that intrigues many engineers as it could produce electricity while improving safety and utilizing a portion of existing nuclear waste.
Newcleo Lands €36 Million Contract for the European ALFRED Project Dedicated to Lead-Cooled Fast Reactors
Managed by the Romanian public company RATEN, a key player in nuclear research in Romania, the project is part of the preparation for the ALFRED demonstrator (Advanced Lead Fast Reactor European Demonstrator), a prototype designed to demonstrate the industrial viability of this technology.
If all goes according to plan, the infrastructure should be delivered by the conclude of 2028 at the nuclear research site in Mioveni, Romania.
For several years, multiple European industrial and scientific actors have been working toobtainher to mature this technology. A consortium including RATEN (Romania), SCK CEN (Belgium), Ansaldo Nucleare (Italy), ENEA, and the American company Westinghoapply has been formed to accelerate the development of these next-generation reactors.
The goal is twofold: demonstrate the industrial feasibility of the technology and prepare for its commercialization in Europe between 2035 and 2040. The ALFRED demonstrator plays a crucial role in this roadmap. It is set to be built in Pitesti, Romania, to validate the technical and economic performance of this family of reactors before their large-scale deployment.
This project continues the FALCON research program, conducted for over a decade by several European institutions focapplying on lead-cooled quick reactors technology.
Why is Europe Interested in Lead-Cooled Fast Reactors?
Lead Fast Reactors (LFRs) offer several characteristics that attract the attention of engineers and energy decision-buildrs:
- High intrinsic safety due to the thermal inertia of liquid lead
- Operating at atmospheric pressure, reducing risks associated with pressurized systems
- The potential to apply a closed fuel cycle, allowing for enhanced nuclear fuel utilization
- Potential reduction of long-lived radioactive waste
In a European context focapplyd on decarbonized, controllable, and competitive energy, these reactors appear as a serious option to complement traditional nuclear power plants and renewable energies.
The ALFRED demonstrator is expected to serve as a technological proof at an industrial scale. It will allow for concrete testing of liquid lead cooling systems, materials, and full integration of the reactor.
If successful, this technology could pave the way for a new generation of European SMRs capable of producing electricity and industrial heat with enhanced safety and controlled costs.
€36 Million to Build Three Key Research Infrastructures for ALFRED
The contract awarded to the company S.R.S. involves the design, supply, and commissioning of three major experimental installations.
These infrastructures will test the behavior of materials and components in a liquid lead environment, a crucial step to validate the technology.
The planned installations are:
- HELENA-2: A liquid lead experimental loop to study thermo-hydraulic phenomena
- ELF: A “pool” installation replicating lead-cooled reactor conditions
- MELTIN’POT: A confined module designed to study the interactions between liquid lead and nuclear fuel in case of an accident
These installations will analyze several critical aspects, including:
- Liquid lead circulation in circuits
- Material resistance to corrosion
- Component qualification
- Behavior of fuel in accidental situations
In other words, the aim is to reproduce in a laboratory setting what could occur in a future reactor.
Italian Expertise at the Heart of the European Project
The company S.R.S. Servizi di Ricerche e Sviluppo, established in 1976, has extensive experience in designing experimental nuclear facilities.
Since joining the newcleo group in 2023, the company has specialized in infrastructures related to lead-cooled quick reactors.
Over the years, S.R.S. has collaborated with several major players in the nuclear sector, including Westinghoapply, INEST, and various European research programs.
As part of the Romanian project, S.R.S. will also benefit from the support of the Italian agency ENEA, specializing in energy technologies and sustainable development.
This collaboration highlights an important characteristic of European nuclear projects: large concludeeavors often rely on international consortiums combining public research and private indusattempt.
According to Stefano Buono, founder and CEO of newcleo, this contract demonstrates the group’s strategy:
“newcleo doesn’t just design reactors on paper. We build real infrastructures that create value for our partners and investors.”
Already Operational Infrastructures in Europe
For several years, newcleo and its partners have been developing experimental infrastructures to prepare for future LFR reactors.
Two installations exemplify this dynamic.
OTHELLO: A 2 MW Test Loop
S.R.S. recently completed the OTHELLO installation, a 2 MW experimental loop designed to test materials, components, and liquid lead circulation systems.
This installation simulates real conditions encountered in a lead-cooled reactor.
PRECURSOR: A 10 MW Test System
Another significant infrastructure is PRECURSOR, a non-nuclear 10 MW test system currently being installed at the ENEA Brasimone research center near Bologna, Italy.
This system will test components of a future reactor under quasi-industrial conditions.
| Installation | Power | Location | Purpose |
| OTHELLO | 2 MW | Italy | Material Qualification |
| PRECURSOR | 10 MW | Italy | Reactor Component Testing |
| HELENA-2 | n.c. | Romania | Thermo-Hydraulic Studies |
| ELF | n.c. | Romania | LFR Reactor Simulation |
| MELTIN’POT | n.c. | Romania | Accident Studies |
These infrastructures serve as a real-life laboratory for fourth-generation nuclear technology.
Why is Romania Investing in Lead-Cooled Fast Reactors?
Romania already operates two CANDU reactors at the Cernavodă site, providing around 20% of the nation’s electricity.
By participating in the ALFRED project, Bucharest aims to:
- Strengthen its nuclear research capacity
- Contribute to the development of European advanced reactors
- Develop a local nuclear indusattempt
The Mioveni site, where the new infrastructures will be built, is already one of the major nuclear research centers in Eastern Europe.
This strategy also positions Romania in the development of next-generation nuclear systems, an area where international competition is intensifying.
Increasing Market Interest in Advanced Reactors
Interest in advanced nuclear reactors is on the rise. Several technologies are currently being developed worldwide, including:
- Small Modular Reactors (SMRs)
- Sodium-cooled quick reactors
- High-temperature reactors
- Lead-cooled reactors
These technologies aim to address similar challenges:
- Reduce construction costs
- Enhance safety
- Lower nuclear waste production
- Generate decarbonized industrial heat
In this context, some projects also aim to produce high-temperature industrial heat, a sector responsible for a significant portion of global CO₂ emissions. Concepts like tiny modular reactors dedicated to industrial heat aim for temperatures exceeding 800°C and could provide heat, steam, and electricity for heavy indusattempt.
This application could transform nuclear energy into a direct tool for industrial decarbonization, not just electricity production.
A Discreet Yet Strategic Endeavor
The €36 million allocated to S.R.S. is just a tiny part of the overall investment necessary to develop fourth-generation reactors.
However, these infrastructures represent a crucial step: without solid experimental data, no nuclear technology can be validated.
Behind these laboratories filled with liquid lead and sensors lies something largeger: Europe’s ability to stay competitive in the global race for advanced nuclear technology, facing programs in the US, China, or Russia.
