Summary
Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world's worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep inside a mangled reactor hall. Sensors are tracking a rising number of neutrons, a signal of fission, streaming from one inaccessible room. The neutron counts are rising slowly, suggesting managers still have a few years to figure out how to stifle the reactions. There's no chance of a repeat of 1986, when an explosion and fire sent a radioactive cloud over Europe. A runaway fission reaction in a fuel mass could sputter out after heat from fission boils off any water it contains. But even a contained flare-up could bring down parts of the rickety concrete and steel "sarcophagus" that entombs the ruined reactor.
