"The scenario of undermining the cooling system of the ZNPP: about a global catastrophe without unnecessary guesswork"

If ZNPP is detonated by Russia🧵

"...on June 21, the IAEA officially confirmed that it is aware of mining at the ZNPP, including the area near the cooling pond, as well as certain places in the middle of the plant. And the question of cooling the station is one of the critical problems."

"And the first thing that should be understood is that there will be significant differences between the accidents at the Chernobyl nuclear power plant and the possible catastrophe at Zaporizhzhya in any case. This is due to the fact that RBMK reactors were used at the...

...Chernobyl Nuclear Power Plant, and VVER-1000 reactors were used at the ZNPP, which are considered much safer and much smaller in size. In particular, the reactor itself is located in the middle of a hermetic "cylinder" with a height of more than 50 meters, a diameter of...

BLUF: Safer reactors at ZNPP than Chernobyl, next:

"Thus, in the absence of cooling in the VVER-1000 power unit, which was operating, the active zone of the reactor will begin to melt after approximately two hours, and...

...the depressurization of the heat-separating elements will occur after approximately 2 hours and 40 minutes. After about 5.5 hours, the reactor body will be destroyed and the melt from nuclear fuel, metal and concrete will melt the foundation to the ground."

BLUF: It melts real good if the Russians sabotage the cooling system with explosives.

But it won't penetrate the foundation or cause a steam explosion without further Russian explosives breaching containment.

"Termination of the cooling system of the ZNPP holding pool
At the same time, in addition to cooling the reactor itself, water is also needed to cool the spent fuel storage pool. The scientific work of Ukrainian nuclear scientists ("Analysis of a severe accident in the spent

...fuel storage pool for the VVER-1000 power unit using the MELCOR 1.8.5 calculation code"), which was published in 2012, is also devoted to this scenario. Note that the holding pool is located next to the reactor in a common hermetic space.

This process no longer depends

...much on whether the power units are in "cold shutdown" or not. And during the simulation, the scenario of the cooling system power supply interruption was also considered. Behind it, after 8 hours, the shells of heat-dissipating elements will be damaged.

After 11.5 hours, the water from the pool will completely evaporate, and after 20.5 hours, the concrete floor of the pool will be burned with melt to a depth of 1.2 meters. This process will be accompanied by the release of hydrogen, but it must be absorbed by the safety

BLUF: Just under two days after Russia blows a hole in the ZNPP retaining pond, the reactor will melt down from lack of cooling water.

My view is that the Western fecklessness after the Russian destruction of the Nova Kakhovka dam - I'm looking at you NSA Sullivan - makes the Russian destruction of the ZNPP inevitable.

I hope I'm wrong.

I fear I'm not.
