Flamanville 3 Nuclear Reactor Begins Operations After Long Delays in France
France’s nuclear energy sector reached a significant milestone as the Flamanville 3 European Pressurised Reactor in Normandy was successfully connected to the national electricity grid. According to reports, this reactor, now the country’s most powerful with a capacity of 1,600 MW, began supplying electricity at 11:48 am local time on Saturday. Officials from EDF, the state-owned energy firm, highlighted to the media that the connection marks an important chapter in the nation’s energy strategy, despite facing years of technical issues, delays, and cost overruns.
Decades in the Making
The Flamanville 3 project, initiated in 2007, was designed to revive interest in nuclear energy across Europe following past disasters. Reports have indicated that its advanced pressurised water reactor technology offers increased efficiency and improved safety measures. EDF’s CEO, Luc Rémont, called the development “historic,” noting that it was the first new reactor to begin operations in France in 25 years. Challenges during the reactor’s construction phase extended its timeline to 17 years, with costs escalating from an initial €3.3 billion to an estimated €13.2 billion.
Testing Phase and Future Plans
As per reports, it has been confirmed by EDF that Flamanville 3 will undergo extensive testing at varying power levels until summer 2025. A full inspection, lasting approximately 250 days, is expected to occur in spring 2026. The facility is projected to supply power to over two million homes once fully operational. France’s nuclear programme remains one of the most prominent globally, contributing to about 60 percent of the nation’s electricity output.
Government’s Commitment to Nuclear Energy
President Emmanuel Macron has underscored the importance of nuclear energy in the country’s shift towards sustainable power sources in the media. The government has announced plans for six additional next-generation reactors and possible options for eight more, reflecting its commitment to reducing dependence on fossil fuels. Macron previously described nuclear development as essential to safeguarding both energy security and the climate.

Efforts to improve data centre efficiency have led mathematicians at Virginia Tech to develop a novel method of data storage and retrieval. According to reports, the researchers have utilised algebraic geometry to tackle issues arising from high energy consumption in data centres, which is impacting global climate goals. This breakthrough was detailed in IEEE BITS, where the team presented a fresh approach to managing the growing volume of data generated by individuals and corporations.
Innovative Use of Algebraic Structures
As per a report by Phys.org, tt was explained by Gretchen Matthews, professor of mathematics at Virginia Tech and director of the Southwest Virginia node of the Commonwealth Cyber Initiative, that conventional methods of data replication often result in duplicating vast quantities of information. As reported, Matthews noted that smarter alternatives could significantly reduce such redundancy. Hiram Lopez, assistant professor of mathematics, added that the new method employs algebraic structures to fragment data and distribute it across servers positioned in close proximity. This ensures that, in the event of server failure, the missing data can be recovered through neighbouring servers without extensive energy use.
Mathematics Behind the Solution
The use of special polynomials for data storage was highlighted as a significant advancement. Although polynomials have been linked to data storage since the 1960s, recent developments have made them more practical for applications like localised data recovery. Matthews pointed out in IEEE BITS that these structures offer an efficient and reliable way to manage data, addressing issues related to storage and retrieval energy demands.
Addressing Rising Power Consumption
The method arrives at a critical time, as energy demand across the United States continues to rise, driven by the increasing number of data centres. Matthews emphasised in the publication that sustainable improvements in existing systems could play a vital role in managing energy consumption.

Research published in Physical Review Fluids has revealed the intricate dynamics between raindrops and leaves, shedding light on how plants withstand the force of falling water. The study, titled “Resonance and Damping in Drop-Cantilever Interactions,” highlights the mechanics that protect leaves and suggests innovative applications for agriculture and renewable energy. Using high-speed imaging, researchers observed the interaction between water droplets and a plastic beam, which simulated the structural behavior of leaves.
According to Professor Sunghwan Jung, from Cornell University’s Department of Biological and Environmental Engineering, in a statement, the droplet and beam move in opposing directions upon impact. This counteraction reduces vibration, offering protection to the plant. The findings align with unexplained discrepancies previously noted by scientists, which the team analysed by examining the natural frequency alignment of the beam and droplet.
Insights into Plant Adaptation
Lead author Crystal Fowler, a doctoral candidate in biological engineering, stated that the study confirmed increased damping when the droplet’s natural frequency matched the beam’s. This phenomenon resulted in a faster reduction of vibrations, potentially reducing stress on plant leaves and contributing to their longevity. The findings may also enhance understanding of water flow through forest canopies and plant morphological evolution.
Potential for Renewable Energy Applications
The research team proposed that the principles observed could extend to renewable energy. Professor Jung suggested piezoelectric materials could replace the beam to harness energy from rain-induced vibrations.
This paper marks a significant milestone for Fowler, a member of the Navajo Nation. Reflecting on her experience, she expressed enthusiasm for exploring biological engineering and its broader implications. The study not only provides a glimpse into plant resilience but also opens avenues for innovative technology inspired by natural processes.
