Chernobyl Nuclear Power Plant Loses Power Again

The New Safe Confinement over reactor 4 at Chernobyl Nuclear Power Plant Tim Porter

What is the Danger?

…[the] heat load of spent fuel storage pool and volume of cooling water at #Chornobyl Nuclear Power Plant sufficient for effective heat removal without need for electrical supply — IAEA tweet March 9, 2022

…there are some 20,000 assemblies at the site, each generating an average of the order of 35 Watts of heat…in the event of a complete and sustained loss of power, the water in the cooling pools would only reach around 60C (over several weeks) before heat loss at the surface was sufficient to reach equilibrium — though the water level would obviously have to be kept topped up — and second that even if all the water escaped the maximum temperature that the most active assemblies would reach would be of the order of 300C, well within the normal operating temperature when it was in the reactor and for which its zirconium cladding was designed
