Despite the objections of local fishermen, the tritium-tainted water stored at the Fukushima No. 1 nuclear plant will be dumped into the sea, a top official at Tokyo Electric says.
"The decision has already been made," Takashi Kawamura, chairman of Tokyo Electric Power Company Holdings Inc., said in a recent interview with the media.
Tritium typically poses little risk to human health unless ingested in high amounts, and ocean discharges of diluted volumes of tritium-tainted water are a routine part of nuclear power plant operations. This is because it is a byproduct of nuclear operations but cannot be filtered out of water.
