Le pari nucléaire de l'Inde commence à porter ses fruits.
Le réacteur surgénérateur rapide de l'Inde, situé dans l'État du Tamil Nadu, a atteint la criticité au début du mois , le rendant autonome et faisant de lui la deuxième centrale commerciale de ce type au monde

India's fast breeder reactor in Tamil Nadu achieved criticality earlier this month, making it self-sustaining and only the second commercial plant of its kind in the world.
The 500-megawatt plant advances India's goal of reaching 100 gigawatts of nuclear capacity by 2047, up from roughly 9 gigawatts today.
While the milestone is significant, experts warn India's 'all of the above' energy strategy may need to become more targeted as demand grows.
India has reached a milestone in its nuclear energy program through its state-of-the-art fast breeder reactor, signalling a major step forward for the clean energy transition in the world’s most populous country. The country’s most advanced nuclear reactor reached criticality earlier this month, meaning that the nuclear chain reaction powering the plant is self-sustaining. This breakthrough will ultimately allow India to import far less uranium to power its nuclear program, and can be adapted to use domestic thorium reserves for fuel in a win-win for the subcontinent’s energy security and autonomy.
When the plant comes online fully, it will be only the second commercial breeder plant of its kind in the world. The other is in Russia. These plants could change the nuclear landscape completely, as they are capable of producing more fissile material (in essence, nuclear fuel) than they consume. Indian Prime Minister Narendra Modi hailed the achievement as “a proud moment for India” and “a defining step” in advancing India’s nuclear program.
“This advanced reactor, capable of producing more fuel than it consumes, reflects the depth of our scientific capability and the strength of our engineering enterprise. It is a decisive step towards harnessing our vast thorium reserves in the third stage of the programme,” Modi said in a post on X on Monday.
This achievement is a long time in the making. The plant, based in the Southern Indian state of Tamil Nadu, has been in development since 2000. It’s not yet clear when the plant will come online, but it is expected to generate 500 megawatts of carbon-free electricity. This will represent a major step toward India’s aim to achieve 100 gigawatts of capacity by 2047, a significant boost from today’s level of approximately 9 gigawatts.
At present, nuclear power accounts for just 2% of India’s energy mix, but the carbon-free form of energy production will be a critical part of India’s decarbonization strategy. India is currently between a rock and a hard place when it comes to balancing energy security and sustainability with the nation’s humans and economic development goals.
Despite considerable economic development in recent decades, India remains one of the poorest countries in the world, and increasing energy access is a central platform of India’s continued climb out of poverty. “Tackling the energy access gap is a critical step in meeting the country’s economic and social development ambitions, and it has been a top priority for successive Indian governments,” says a Guardian report from September of last year.
Meeting the energy needs of all 1.47 billion people in India without majorly derailing global climate goals will require enormous investments in a wide array of traditional and innovative energy alternatives. India is already the third-largest energy consumer in the world after the United States and China, and its needs will only continue to grow. Nuclear, and next-gen nuclear such as breeder reactors, will be just one component of a diverse energy portfolio.
While the fast breeder reactor marks a major step forward for Indian energy innovation, it likely won’t provide a silver-bullet solution to the subcontinent’s energy challenges. Many other nations have pursued the development of such models, including the United States, China, France, and South Korea, but most have abandoned the pursuit in favor of other next-gen nuclear models that they see as more promising, such as small modular reactors. However, even if this form of reactor doesn’t become the new normal for India, it will still serve the country’s overall energy ambitions, which include a diverse energy playing field. But, going forward, a more streamlined approach may be necessary.
“India’s energy transition goals have always been an ‘all of the above’ approach, to increase capacity from fossil and non-fossil sources as part of its broader economic growth aspirations – and in response to growing demand,” Ashwini Swain, an energy transition expert at the Delhi-based Sustainable Futures Collaborative, told The Guardian. “So far the approach has mostly been ad hoc and supply-centric rather than targeted to end users, because it comes from a scarcity mindset,” Swain went on to say. “This has worked out so far, but India has reached a stage where we need a much more strategic whole systems approach to energy transition.”
Le principal oléoduc d'Arabie saoudite remis en service après une attaque de drone
« Ce rétablissement rapide témoigne de la grande résilience opérationnelle et de la gestion de crise … »
A key Saudi oil pipeline to the Red Sea was restored on Sunday and is now pumping at full capacity after an Iranian drone attack last week damaged a pumping station.
The East-West pipeline is back at full capacity, moving about 7 million barrels per day and restoring critical energy flows from Saudi's Persian Gulf oil fields to the Red Sea port of Yanbu, bypassing the turmoil in the Strait of Hormuz.
Bloomberg quoted the Saudi energy ministry as saying that Saudi Aramco's offshore Manifa field has been restored, while repairs continue at the Khurais onshore complex. Last week, attacks on Manifa and Khurais each knocked out about 300,000 bpd.
"This quick recovery reflects the high operational resilience and crisis management efficiency of Saudi Aramco and the kingdom's energy ecosystem as a whole, thereby enhancing the reliability and continuity of supplies to local and global markets," the energy ministry said.
The Iranian attack on the pipeline last week came on the same day the U.S. and Israel agreed to a two-week ceasefire. By Sunday, after a marathon round of talks in Islamabad between Vice President JD Vance, U.S. negotiators, and Iranian negotiators, no peace deal was reached, but the door was left open for future diplomacy.
"We leave here with a very simple proposal: a method of understanding that is our final and best offer," Vance told reporters earlier. "We'll see if the Iranians accept it."
On Saturday, the U.S. Department of War confirmed that two U.S. warships transited the Hormuz chokepoint to begin marine mine-clearing operations. Only a handful of ships have transited the critical waterway, as traffic remained muted late into the weekend.
