The plant’s operator, Tokyo Electric Power (Tepco), has tried everything to contain the resulting buildup of contaminated groundwater, but recent reports indicate that they have effectively lost the war.
The go-to solution has been to store 1 million tons of the toxic water in 1,000 tanks at the site, but the company has now warned that it will have run out of tank storage by mid-2022. The proposed solution? After going to such great lengths to contain the water because of its toxicity, Tepco is now insisting that it can safely be diluted by being drained into the sea.
As explained by Encyclopedia Britannica, first the Fukushima area was battered by a magnitude 9.0 earthquake. Then, two days later, a massive, 50-foot tsunami made landfall, damaging the power plant’s backup generators. The three reactors operating at the time were successfully shut down, but the loss of power caused by the generator failure meant the reactors’ cooling systems failed within days. The resulting high temperatures caused the fuel rods to overheat and start to melt, releasing radiation in the process.
Workers pumped cool seawater and boric acid into the units to try to cool them, but it was later discovered that some of the melted material had caused large holes at the bottom of the vessels, partially exposing nuclear material.
Even though the nuclear disaster in Fukushima took place over seven years ago, radioactive waste has continued to build up as ground water flows through the destroyed reactor buildings and becomes contaminated. This creates a staggering 160 tons of contaminated water each day.
While the purification devices used by the Tokyo Electric Power Company (TEPCO) do remove most of the radioactive materials, a radioactive isotope of hydrogen known as tritium cannot be removed, and tritium-contaminated water continues to cause big problems.
Officials from both Tepco and the Japanese government now insist that since tritium exists in nature, dumping this water in the ocean is a perfectly safe solution to the problem.
“The only option will be to drain it into the sea and dilute it,” Yoshiaki Harada, a Japanese politician, told a news briefing held in Tokyo recently. “The whole of the government will discuss this, but I would like to offer my simple opinion.”
According to the Guardian, recent studies have found that it would take around 17 years to get contamination levels low enough to meet the plant’s safety standards.
Local fishermen have expressed anger at the idea of toxic water being dumped into the ocean, and South Korea has voiced concerns about the potential impact on the reputation of its own fishing industry.
Meanwhile, there is evidence that Fukushima radiation is already causing harm to animals and marine life as far away as the west coast of the United States:
Imagine the dire consequences if Tepco starts actively dumping contaminated water directly into the ocean!
