Romania deployed four rock-filled barges in the Danube to redirect water toward the Cernavodă nuclear plant to protect cooling-water supplies during severe drought; unexpectedly, the river level rose 1.6 inches in 24 hours, contrary to forecasts, potentially sustaining plant operations for about nine days. The facility's two CANDU-6 reactors normally generate roughly 18-20% of Romania's electricity.
Hungary is grappling with a severe drought that has emptied lakes and driven the Danube to historic lows, threatening energy production at the Paks nuclear plant and prompting a government-wide shift to water-retention and conservation, including fixing leaky pipes. Experts say restoring wetlands could help buffer future dry spells as climate change intensifies rainfall extremes.
The piece argues that youth pessimism about the climate is driven in part by a gap in energy-focused teaching: teachers spend little time on climate and energy, students rely on social media for information, and many lack basic energy literacy. It notes rising electricity demand and strong job opportunities in energy and nuclear sectors, advocating for structured energy education through programs like Generation Atomic and Blue Energy Nation to counter doomism and better prepare students for a changing labor market.
Two 260-foot barges are being sunk into the Danube to raise water levels amid a drought that has driven the river to record lows, a move aimed at ensuring cooling water for Hungary’s Paks nuclear plant, which supplies about half of the country’s electricity; levels are currently about 48 inches below normal and could drop further, risking a turbine shutdown.
Romania’s sole nuclear plant at Cernavodă is offline due to heat-driven low Danube water levels, with restart not expected for at least 10 days and about 20% of the country’s electricity supply at risk.
Romania shut down the second unit at the Cernavodă nuclear plant after drought‑reduced Danube water prevented cooling, taking about 700 MW offline (roughly 10% of Romania’s electricity) and following Unit 1’s earlier closure. The grid remains stable per authorities and will be bridged with imports, hydropower, wind, coal and reserve generation, with officials warning the Danube’s flow is expected to keep falling in the coming days, delaying any restart.
NASA researchers at JPL tested a lithium-fed, high-power electric thruster at up to 120 kilowatts—far beyond current systems. When paired with a nuclear power source, the technology could reduce one-way Mars travel to about three months and bring the total round trip to roughly two years, though the work is in early testing and would require further demonstrations and integration.
Romanian authorities rushed to sink four barges into the Danube to secure the cooling-water intake for the nuclear plant’s second reactor, a move aimed at preventing a shutdown and keeping the facility operating amid pressing reliability concerns.
Hungary faces a critical five days as a record drought forces the shutdown of the Paks Nuclear Power Plant, which normally supplies about 40% of the country’s electricity. The outage prompts energy-saving measures, calls to reduce peak-hour consumption, and potential industrial curbs, while authorities and neighbors prepare contingency steps and the EU monitors the situation amid forecast heat and drought across Europe.
NASA plans to launch Dragonfly in July 2028—a car-sized, 1,000-pound plutonium-powered drone that will autonomously hop across Titan’s surface for about six years on a roughly $3.35 billion mission. With eight rotors and autonomous navigation, it will fly roughly 30-minute legs at about 22 mph, using a plutonium MMRTG to power the lab-sized payload of DraMS, DraGNS, DragonCam, and DraGMet. Titan’s dense atmosphere and low gravity make flying easier than on Earth, and the mission will operate largely without real-time Earth control due to long signal delays, aiming to study prebiotic chemistry and the potential subsurface ocean beneath Titan’s icy crust.
The US formally concluded a 123 Agreement to help Saudi Arabia develop civilian nuclear power, but Trump then posted that the deal would be conditioned on Saudi Arabia joining the Abraham Accords with Israel. Analysts say this unexpected demand likely derailed the pact, with concerns that the deal gave Riyadh too much leverage, opposition from Israel and other Gulf partners, and bipartisan resistance in Congress. In short, Trump’s last‑minute move appears to have blown up a signed nuclear deal and angered Saudi leaders while leaving questions about U.S. regional strategy.
NASA plans to launch Dragonfly, a car-sized eight-rotor rotorcraft powered by a plutonium-238 RTG, to hop between sites on Saturn’s moon Titan. The drone will study Titan’s methane seas, organic-rich dunes, and prebiotic chemistry, exploring how carbon chemistry progresses in environments unlike Earth. Dragonfly could travel up to ~175 km during its nominal mission, arriving at Titan no earlier than 2028 and reaching the world by 2034, using heat from its power source to keep instruments warm in Titan’s frigid environment.
President Trump said Saudi Arabia must normalize relations with Israel to receive U.S. nuclear technology, adding a condition to a deal signed a day earlier and casting the pact into doubt as negotiations over Saudi-Israeli ties stall.
The Trump administration signed a nuclear cooperation agreement with Saudi Arabia that would give Riyadh a pathway to enriching nuclear fuel and require US firms to supply its reactors, a move drawing alarm from nonproliferation experts and triggering a 90-day Congressional review.
Despite bold announcements of a nuclear renaissance, few binding deals exist to actually produce power, and experts doubt the plan’s feasibility and economics.
