The location is far too poisoned with radiation for any human to venture in, but they might build a robot that can maneuver into the affected area to spray neutron-stanching chemicals, for example. Now that the NSC keeps the rain out, there isn’t any fresh water flowing in to continue to fuel new reactions.īut if the reaction doesn’t run itself out, the scientists are discussing their options. In that time, they say, the incipient reaction could very well sputter out on its own-especially once the water supply fully dries out. So, what are the next steps? The ISPNPP scientists say the growth in neutron activity is low enough that they still have a few years before they’ll need to act either way. At NSC, there are hundreds of sensors working around the clock to monitor factors like air quality, and the sensors have detected increased neutron activity near the fallen reactor hall where the “embers” are. The telltale sign is increased readings of neutron activity-a measurable byproduct of nuclear fission, according to the scientists from Institute for Safety Problems of Nuclear Power Plants (ISPNPP) in Kyiv, Ukraine, who held discussions about dismantling the reactor last month, according to Science magazine.Ĭhernobyl Nuclear Power Plant is surrounded by a massive megastructure called Chernobyl New Safe Confinement (NSC). Ukrainian scientists recently realized that leftover nuclear fission fuel made of uranium has begun reacting again in an “inaccessible room” deep within a damaged area of the shuttered plant. Now, thirty-five years later, smoldering nuclear “embers” are still buried within Chernobyl site, raising questions about just what might happen there-and what’s at stake. 4 exploded at the Chernobyl Nuclear Power Plant in Ukraine, causing the worst nuclear accident in history. The reaction could burn out naturally, but it could also require human intervention. The issue is rainwater, which has activated materials buried deep within the closed plant. A melted amalgam of nuclear fuel at Chernobyl is beginning to react. ![]()
