On Feb. 25, against a clear sky, fishing boats bearing colorful banners used to signal a rich haul returned to their home port of Ukedo in the town of Namie, Fukushima Prefecture. Cheers erupted as the boats, which had taken refuge in Minamisoma in the wake of the 2011 Great East Japan Earthquake and the nuclear crisis, made their way home for the first time in six years.
The Soma-Futaba fishing cooperative will soon resume fishing for konago (young lancefish), after the heads of fishing co-ops in the prefecture approved the start of experimental fishing operations 10 to 20 km from the meltdown-hit Fukushima No. 1 power plant, run by Tokyo Electric Power Co. Holdings Inc.
Despite the steady recovery moves, however, local fishermen are not optimistic because their industry still faces “concern” that radioactive fish could tarnish their reputation.
Fukushima No. 1 currently has 950,000 tons of radioactive water in storage that has been desalinated and filtered to remove some of the radioactive elements, but the volume is increasing at a pace of 150,000 tons a year.
Of the 950,000 tons, 750,000 were further treated with the Advanced Liquid Processing System, to remove most of the remaining isotopes. But even ALPS cannot remove tritium, and this has the fishing industry concerned that water tainted with tritium could ultimately be released into the ocean.
The debate over what to do about the tainted water has turned into a standoff. The central government set up a committee in September to discuss disposal and studied five options, including ocean release, underground burial and air release. But the committee could not agree on any of them because all had the potential to damage the reputation of Fukushima’s seafood.
Hiroshige Seko, head of the Ministry of Economy, Trade and Industry has jurisdiction over the issue but appears reluctant to bring the debate to a rapid conclusion.
“We have not decided on the schedule, including when to conclude (the debate),” he said in a recent interview with the Fukushima Minpo.
Tritium is a common byproduct of normal nuclear power plant operations. Its release into the ocean is permitted worldwide as long as the concentration doesn’t exceed certain levels. In Japan, the legal threshold for tritium release is 60,000 becquerels per 1 liter.
Shunichi Tanaka, chairman of the Nuclear Regulation Authority, has said “there is no solution than ocean release” for the tritium generated at Fukushima No. 1, noting that if the concentration is within legal limits, the government should go ahead with the release. Officials at related international institutions have expressed similar views.
But the prefectural association of fishing cooperatives remains opposed, worried that an ocean release could further damage the image of Fukushima’s fish and seafood.
A fisherman from Onahama in the city of Iwaki said, “The move could lead to a loss of trust in the prefecture’s seafood, which the fishermen have worked hard to build.”
On the other hand, if the disposal debate goes unresolved, the amount of tainted water at Fukushima No. 1 will continue to rise and delay the decommissioning of the plant.
Tepco has said it “will decide (on the fate of the water) in a responsible manner by watching the government debate and weighing the opinions of local residents.”
The fishery industry is watching how the central government balances the two jobs of revitalizing the industry and handling tritium-tainted water — and how it can thoroughly explain the decision in ways people both in Japan and abroad can understand, without leaving it entirely up to Tepco.
