Fukushima operator restarts key water decontamination system after repairs

The operator of Japan’s crippled Fukushima nuclear plant said Monday it has switched on a key decontamination system that cleans radiation-tainted water used to cool the site’s damaged reactors. Last week, Tokyo Electric Power (TEPCO) said it had discovered a defect in its Advanced Liquid Processing System (ALPS) and switched…

Groundwater radiation spikes at crippled Fukushima nuclear power plant

Groundwater radiation levels at Japan’s crippled Fukushima nuclear plant have soared near a tank that leaked 300 tonnes of toxic water in August, struggling operator Tokyo Electric Power said. TEPCO said water samples collected from a well on Thursday contained 400,000 becquerels per litre of beta-ray emitting substances, the highest…

Four tons of radioactive water spilled in accident at Fukushima nuclear plant

The operator of the crippled Fukushima nuclear plant said Tuesday workers had spilled four tonnes of radioactive water, likely contaminating the soil and possibly groundwater. Workers were pumping rain water that was trapped in a concrete gutter into an empty 12-tonne tank that sat on open soil, said a spokesman…

1,000 tonnes of polluted Fukushima water dumped in sea after Typhoon Man-yi

The operator of the leaking Fukushima nuclear plant said Tuesday that it dumped more than 1,000 tons of polluted water into the sea after a typhoon raked the facility. Typhoon Man-yi smashed into Japan on Monday, bringing with it heavy rain that caused flooding in some parts of the country,…

Japan nuclear agency says Fukushima water leak risk exaggerated

The chief of Japan’s nuclear watchdog chided the operator of the Fukushima plant Thursday for its inability properly to explain problems, which he said was inflating fears around the world. Shunichi Tanaka, chairman of the Nuclear Regulation Authority, said information given by Tokyo Electric Power (TEPCO) on the level of…

Japan unveils $500 million ice wall plan for Fukushima water leaks

Tokyo on Tuesday unveiled a half-billion dollar plan to stem radioactive water leaks at Fukushima, creating a wall of ice underneath the stricken plant, as the government elbowed the operator aside. Acknowledging global concerns over a so-far “haphazard” management of the crisis by Tokyo Electric Power (TEPCO), Prime Minister Shinzo…

More radiation ‘hotspots’ found near Fukushima nuclear plant

The operator of Japan’s stricken Fukushima nuclear power plant said Saturday it had found new radiation hotspots near tanks storing toxic water, with one reading peaking at 1,800 millisieverts per hour — a potentially lethal dose. Tokyo Electric Power Co (TEPCO) detected high radiation readings at four sites around the…

Fukushima plant operator cannot confirm volume of contaminated water leaking into ocean

TOKYO (Reuters) – Tokyo Electric Power Co, the operator of the crippled Fukushima nuclear plant, said on Wednesday that it cannot confirm the exact volume of contaminated groundwater that is leaking into the ocean. The Japanese government believes radiation-contaminated water has been leaking into the Pacific Ocean at a rate…

Japan ‘was unprepared’ for nuclear disaster

TOKYO — The operators of the tsunami-stricken Fukushima nuclear power plant and government regulators were woefully unprepared for disaster, the first official probe into the March 11 catastrophe said Monday. An independent panel set up to investigate the events around the world’s worst nuclear accident in a generation said Tokyo…

Japan nuclear meltdown ‘maybe worse than thought’

Molten nuclear fuel at Japan’s Fukushima plant might have eaten two thirds of the way through a concrete containment base, its operator said, citing a new simulation of the extent of the March disaster. Tokyo Electric Power (TEPCO) said their latest calculations showed the fuel inside the No. 1 reactor…
