Technicians at Japan’s wrecked Fukushima nuclear power plant have acknowledged neglecting to investigate the cause of faulty exhaust filters key to preventing radioactive pollution, after being forced to replace them twice. Representatives of the Tokyo Electric Power Company made the revelations Monday during a regular review of the Fukushima Daiichi plant at a meeting with Japanese regulatory authorities. The plant suffered triple meltdowns following a massive earthquake and tsunami in 2011. “At the core of this problem is TEPCO´s attitude,” said a Nuclear Regulation Authority commissioner, Nobuhiko Ban, at the meeting. TEPCO has been repeatedly criticized for coverups and delayed disclosures of problems at the plant. In February, it said two seismometers at one reactor remained broken since last year and failed to collect data during a powerful quake. Company officials have said that 24 out of 25 filters attached to water treatment equipment had been found damaged last month, after an alarm went off as workers were moving sludge from the unit to a container, temporarily suspending the water treatment. The operation partially resumed last week after filter replacement. The filters are designed to prevent particles from escaping into the air from a contaminated water treatment system – called Advanced Liquid Processing System, or ALPS – that removes selected radioactive isotopes in the water to below legally releasable limits.
