A single uranium-235 fission releases about 200 million electron volts — roughly 50 million times what burning one carbon atom yields. That ratio is why a car-sized fuel assembly can power a city for 18 months.
{"content":"On the morning of June 27, 1954, a squat brick building on the edge of a birch forest about 100 kilometres southwest of Moscow began pushing five megawatts of electricity into the Sovie
In January 1995, biologists released fourteen gray wolves into Yellowstone's Lamar Valley after a seventy-year absence. Thirty-one years later, the descendants number about 100 across eight packs — and ecologists are still sorting out which parts of the ecosystem actually changed because of them.
A uranium fuel pellet the size of a fingertip holds roughly the energy of a tonne of coal — and a typical reactor core stacks about ten million of them into twelve-foot zirconium rods. Here's how the math, the metallurgy, and the physics actually work.
On 21 May 1946, physicist Louis Slotin's screwdriver slipped during a criticality demonstration at Los Alamos, sending a plutonium core prompt-critical in a flash of blue light. He pulled the beryllium shell off with his bare hand, shielded seven colleagues, and died nine days later — the second man killed by the same sphere of plutonium, later nicknamed the demon core.
What’s up in
Civil nuclear energy, reactor technology, regulation, safety, fuel cycles, and the policies, projects, and research shaping the future of nuclear power.
Tracking the future of nuclear energy.
Nuclear Power Daily is an independent publication covering civil nuclear energy, reactor technology, regulation, safety, fuel cycles, and the policies and projects shaping nuclear power. The site pairs a deep archive with current reporting on the research, companies, policy shifts, safety debates, and technical breakthroughs shaping the future of nuclear energy. We employ modern AI technologies to support our editorial workflows; every published piece is editorially directed and reviewed.
