Major Initiatives for Water Management
At Fukushima Daiichi Nuclear Power Station, approximately 150 tons of groundwater, which naturally runs from the mountain side to the ocean, flow into reactor buildings and become newly contaminated water. Based on the three basic principles for water management, “REMOVE the source of water contamination”, “REDIRECT fresh water from contaminated areas”, and “RETAIN contaminated water from leakage”, various countermeasures are taken against the estimated risks that the contaminated water may flow out to the port or that the contaminated water may leak from the storing tanks.
- REMOVE the source
of water contamination -
- REDIRECT fresh water
from contaminated areas -
- RETAIN contaminated water
from leakage -
