Chernobyl alert

Like the mythical Phoenix, Chernobyl rises from the ashes.

A recent… “Surge in fission reactions in an inaccessible chamber within the complex” is alarming scientists that monitor the ruins of the Chernobyl Nuclear Power Plant in Ukraine.

It is known that this significant renewal of fission activity is located in Sub-Reactor Room 305/2, which contains large amounts of fissile material from the initial meltdown. The explosion brought down walls of the facility amongst tons of fissile material within the reactor as extreme heat melted reactor wall concrete and steel combined with sand used to control the explosion to form a lava-like intensely radioactive substance that oozed into lower floors, e.g., Room 305/2. That room is so deadly radioactive that it is inaccessible by humans or robots for the past 35 years.

Since 2016, neutron emissions from Room 305/2 have been spiking and increased by 40 percent over the past 5 years. It signals a growing nuclear fission reaction in the room. According to Neil Hyatt/University of Sheffield-UK: “Our estimation of fissile material in that room means that we can be fairly confident that you’re not going to get such rapid release of nuclear energy that you have an explosion. But we don’t know for sure… it’s cause for concern but not alarm,” Ibid.

If it is deemed necessary to intervene, it’ll require robotically drilling into Room 305/2 and spraying the highly radioactive blob with a fluid that contains gadolinium nitrate, which is supposed to soak up excess neutrons and choke the fission reaction. Meanwhile, time will tell whether the monster of the deep in Room 305/2 settles down on its own or requires human interaction via the eyes and arms of a robot, which may not survive the intense radioactivity. Then what?

Meanwhile, an enormous steel sarcophagus, a $1.8bn protective confinement shelter, the New Safe Confinement (NCS) was built in 2019 to hopefully prevent the release of radioactive contamination. NCS is the largest land-based object ever moved, nine years construction in Italy delivered via 2,500 trucks and 18 ships. It is expected to last for 100 years. Thenceforth, who knows?

Nevertheless, according to nuclear professionals, the question arises whether this recent fission activity will stabilize or will it necessitate a dangerously difficult intervention to somehow stop a runaway nuclear reaction.
