Although it has kept its structure intact, Reactor 2 is the current source of the most important radioactive releases into the soil as well as into the sea.
The explosion took place inside the building.
Operators had probably encountered difficulties depressurizing the containment and the wet well suppression pool broke.
This loss of leak-tightness led to the discharge into the atmosphere of unfiltered radioactive elements and to the spreading of highly contaminated water in the buildings, leading to highly polluting discharges into the sea.
