“The stored uranium at Chernobyl doesn’t need active cooling.”

Then why does it need backup generators?

Inside the giant concrete dome weighing 3000 tons, Chernobyl nuclear reactors are still hot(warm). Far less than it used to, though. Constant supply of power are needed to run machines to control water to cool reactors. Without supply of water, temperatures of reactors would slowly rise over months, which could lead to radiation leak. This is not the immediate problem, though.

There was an article around Fukushima disaster that said the giant concrete dome is not a permanent solution and further measure should be taken. So electricy should be always available. Now that power supply is cut, they need backup generators.
