When the Water Runs Dry, the Reactors Stop: Behind Romania Losing One-Fifth of Its Electricity, Heavy-Industry Reactor Designs Are Suffering a Fatal "Cold Source Asphyxiation" — Examining the Physical Interrogation of High-Water-Consumption Baseload Plants by Extreme Drought Through the Prolonged Paralysis of the Cernavodă Nuclear Power Plant

For a long time, nuclear power has been regarded as the unwavering backbone of round-the-clock baseload electricity, immune to weather conditions, cloud cover, or lulls in wind. However, the nearly two-month total shutdown of Romania's Cernavodă Nuclear Power Plant is breaking this industry paradigm in an extreme and brutal manner. Because the Danube River has experienced a historically rare drought exceeding warning thresholds and a cliff-edge collapse in water levels, the country's only nuclear power plant—which safeguards one-fifth of its electricity supply—has been paralyzed by the loss of cooling water assurance, with no prospect of near-term restart. This extreme case not only tears open a massive gap in winter energy security for Romania and even Southeastern Europe, but also sounds an alarm for the global energy community: in the face of increasingly...

Joint Institute for High Temperatures of the Russian Academy of Sciences Discovers a New Phase Transition in Cesium Plasma: Abrupt Conductivity Jump and a Rare Double Critical Point

A research team from the Joint Institute for High Temperatures of the Russian Academy of Sciences (JIHT RAS / ОИВТ РАН) has achieved an important physics advance in the study of extreme high-temperature and high-pressure states: researchers have discovered a previously undescribed phase transition in cesium (Cesium) under dense plasma conditions, accompanied by a dramatic jump-like change in electrical conductivity. The study focuses on the microscopic physical behavior of matter at temperatures from 500 to 20,000 Kelvin (K) and pressures ranging from about 1 hectopascal (hPa) to several terapascals (TPa). Under such severe extreme conditions, interatomic distances are greatly compressed, matter undergoes multiple deep ionizations, and the traditional criteria for distinguishing solid, liquid, and gas states can no longer...
