Chernobyl's Molten Guts Are Warming Up, And Scientists Don't Know Why 12 MAY 2021 Over the past five years, a sensor keeping count of neutron emissions deep within the rubble of the Chernobyl nuclear power plant has kept track of a gradual spike in activity.   The rising count might be nothing. It might even drop back down again, given time. Scientists aren't exactly keen on taking any chances, as the potential for a runaway nuclear fission reaction in the future can't be ruled out until we know what's going on. Unfortunately, the precise location of the decaying material beneath debris an...

May 11, 2021 10:02 PM EDT Nuclear fission reactions have begun to flame up again in an isolated basement room deep inside the ruined pits of the Chernobyl Nuclear Power Plant, 35 years since the world's worst nuclear disaster. (Photo : Pixabay) According to Science Magazine, Ukrainian scientists from the Institute for Safety Problems in Nuclear Power Plants (ISPNPP) recently discovered an extraordinarily high number of neutrons emitting from an inaccessible room in the Chernobyl Nuclear Power Plant indicating that a fission reaction has begun to reoccur. Neil Hyatt, a professor of nuclear mat...

Share Radioactive corridors where Reactor No.4 malfunctioned in the Chernobyl Nuclear Power Plant - and the levels of radiation are fifty thousand times higher than normal At the time, emergency crews responding to the accident used helicopters to pour sand and boron on the reactor debris to extinguish fires. The sand melted with uranium fuel rods and their zirconium cladding, as well as graphite control rods, to form a lava.  The lava flowed into the reactor hall's basement rooms and hardened into highly radioactive formations called lava-like fuel containing materials (LFCMs). A few weeks...

Nuclear reactions are increasing in an inaccessible chamber at Chernobyl CNET 5/12/2021 Steph Panecasio © Provided by CNET The neutron emissions are likened to "embers" -- stable, but capable of sparking in the right conditions. Getty Images - Anadolu Agency / Contributor Radioactive emissions in an inaccessible chamber within the Chernobyl nuclear power plant have spiked in the last four years, leading scientists to question how serious the threat of a runaway nuclear fission reaction really is. The 1986 Chernobyl explosion -- which resulted in catastrophic destruction a...

Konoplytska/Getty Images Scientists monitoring the ruins of the Chernobyl nuclear power plant in Ukraine have seen a surge in fission reactions in an inaccessible chamber within the complex. They are now investigating whether the problem will stabilise or require a dangerous and difficult intervention to prevent a runaway nuclear reaction. Advertisement One chamber, known as subreactor room 305/2, is thought to contain large amounts of this material, but it is inaccessible and hasn’t been seen by human or robotic eyes since the disaster. Now, researchers have seen a spike in neutron emissio...
