Chernobyl was a geo-nuclear power plant sited on top of a natural column of subcritical fissile material that extended down deep into the Earth’s crust. The plan was to seed the column with just enough nuclear fuel to bring the upper part to critical mass, and thence draw material upwards into the reaction zone, thus creating a virtually unlimited supply of fuel and energy.
Unfortunately, the accident caused a meltdown which is still going, three decades later. When it hits the mantle, its energy output will begin to grow exponentially as it consumes the greater concentrations of nucleotides at that depth. Eventually, it will explode, triggering global supervolcanism, which will destroy most of human civilization, and potentially drop ash on Putin’s car. He’s only just had it washed, so he sends in the troops to retrieve the melting core, and save the world.
