Can all the fuel in Units 1~4 be stored in the common pool?

6,799 fuel assemblies can be stored at cool temperatures in the common pool but the common pool is not big enough to store all the fuel.
So, fuel which has dropped in temperature is transferred in dry casks to an air-cooled storage facility. Fuel is thus stored in two ways.

Why is fuel stored in the common pool considered to be safe?

Storing all the spent fuel together in the common pool reduces risk compared with keeping it in the fuel pools of each reactor.
That’s why we are gradually relocating it to the common pool.

What is the grid-like object seen in the common pool?

This is a fuel storage rack. Fuel is stored in racks so it can be easily moved in and out, and to make it easier to keep track of quantity.
