Russia's Nuclear Problem - Joe Blogs



Russia has admitted that the Zaporizhzhia nuclear power plant — Europe’s largest — has once again lost its external power supply after fighting severed the last high-voltage line. The plant is now relying on emergency diesel generators to keep its reactors cooled and prevent meltdown.

In this video, we’ll look at:

• How Zaporizhzhia lost its power lines
• Why cooling systems are vital for nuclear safety
• What could happen if cooling is lost
• How this compares to past disasters like Chernobyl

This is Russia’s nuclear problem — and it could have consequences far beyond Ukraine.

Tchernobyl was a graphite cooled reactor. Fukushima and zapoichia are water cooled reactors. But all reactors today are super critiical reactors, but one : the Belgian Myrrha reactor which is a sub critical reactor. What is the difference? Critical means that even if the plant does not produce electricity, you need electricity to avoid disaster. Because you have so much uranium that once sparked it keeps going. Sub means if you pull the plug, the fission process simply stops
