TerraPower, a nuclear startup founded by Bill Gates, is leveraging its molten salt-cooled reactor with integrated energy storage to provide reliable power for AI data centers, addressing intermittency issues from renewable sources.
St. Lucie Nuclear Power Plant Unit 1 was manually shut down after 3 control rods dropped into the reactor core. The Nuclear Regulatory Commission classified the event as a non-emergency.
NASA completed testing of a lithium-fed electromagnetic thruster that achieves 5x more power than current electric propulsion systems, potentially slashing travel time to Mars when paired with a nuclear power source.
Paul Graham tweets about being impressed by Apollo Atomics, a nuclear power startup he met during office hours, lamenting the decades of neglect of nuclear energy.
Record low Danube water levels force Hungary's only nuclear power plant to shut down, risking critical energy supply during an ongoing heatwave, with Romania also affected.
Atomarine proposes floating data center campuses at sea, powered by gas (and future nuclear reactors), using seawater cooling and standardized barges to bypass grid interconnection delays for AI compute.
An article recounting the 1960 Operation Sandblast, where the USS Triton became the first submarine to circumnavigate the globe while submerged, demonstrating the capabilities of nuclear power.
A newsletter covering a US nuclear milestone with four microreactors achieving criticality, and China planning to let its top AI firms purchase Nvidia H200 chips, alongside other tech stories.
City Labs launched BOHR, the first commercial nuclear-powered satellite, using a betavoltaic battery powered by tritium decay. The mission demonstrates a compact, regulatory-approved nuclear power system for space, enabling persistent power independent of sunlight.
NASA is considering sending a backup nuclear-powered Mars rover, Promise, to the Moon instead, repurposing existing hardware to advance lunar exploration before China's potential landing.
65 years ago, the US Navy's Transit-4A became the first satellite to use nuclear power in orbit with a tiny RTG. Today, modern RTGs like those from Zeno Power can scale output using nuclear waste.
Canada's energy minister announced a plan to build up to 10 new nuclear reactors by 2040 as part of a 'nuclear renaissance' strategy to double the country's electrical grid capacity and create tens of thousands of jobs.
