I don't know why. Please help me.

Flooding the reactor sooner could have avoided the need to vent radioactive steam caused by overheating of fuel rods and an explosion caused when steam from the overheating water reacted with zirconium cladding that holds fuel pellets in the reactor vessel to produce hydrogen,
