US energy utility Southern California Edison has dumped about 70,000 gallons of partially purified wastewater from the San Onofre nuclear power plant, which is in the process of decommissioning, in the Pacific Ocean.
The reason is the sudden influx of water from the NPP that flooded the treatment plant, built specifically to treat the water used by the nuclear facility, said Ron Pontes, a representative of the operator’s management.
“We are now investigating where this large amount of water came from”, said Ron Pontes. “Once we understand, we will rebuild the installation and make sure it works properly and returns it to service”, added he.
Southern California Edison manages the installation that removed the water from the nuclear power plant that was decommissioned in 2012. At present, nuclear waste tanks are being moved from their current location in a wet storage area to dry storage, which will allow the company to begin dismantling the facility .
The US Nuclear Regulatory Commission, San Diego Department of the Environment and California State Parks have been notified of the water release, plant officials said.
