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…

Tepco waited five months before releasing Fukushima data about radioactive strontium-90

By Mari Saito TOKYO (Reuters) – The operator of Japan’s wrecked Fukushima nuclear plant knew about record high measurements of a dangerous isotope in groundwater at the plant for five months before telling the country’s nuclear watchdog, a regulatory official told Reuters. Tokyo Electric Power Co (Tepco) said late on…

Fukushima plant readies for removal of dangerous fuel rods

Nuclear engineers in Japan are readying to move uranium and plutonium fuel rods at Fukushima in their most difficult and dangerous task since the plant’s runaway reactors were brought under control two years ago. Tokyo Electric Power (TEPCO) will this month begin taking out fuel rods from a pool inside…

Fukushima workers evacuated as tsunami hits Japan

Workers at the crippled Fukushima nuclear plant were evacuated when a small tsunami hit Japan after a powerful undersea quake Saturday, highlighting the continued threat to the area devastated by the 2011 quake-tsunami. The government Meteorological Agency warned people to stay away from the Pacific coast for nearly two hours…

Japan nuclear regulator berates Fukushima operator

Japan’s atomic watchdog summoned the boss of Fukushima operator TEPCO on Friday for a public dressing-down over sloppy standards at the crippled nuclear plant, as yet another problem with radiation-polluted water emerged. The Nuclear Regulation Authority (NRA) called in Tokyo Electric Power Co president Naomi Hirose and other executives over…

New radioactive leak reported at crippled Fukushima nuclear plant

A new radioactive water leak has been discovered at Japan’s crippled Fukushima nuclear plant, its operator said on Wednesday, according to Japanese news agencies. Tokyo Electric Power (TEPCO) said the highly radioactive water had leaked at the Fukushima No. 1 plant from a different storage tank to the one where…

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,…

‘Steam seen’ at Fukushima nuclear reactor

Vapour has begun rising again from a reactor at the Fukushima nuclear power plant, more than two-and-a-half years after its core melted down, the site’s Japanese operator said Friday. Tokyo Electric Power said it believed the steam was coming from a puddle sitting atop the reactor and was not dangerous,…

High radiation detected at Fukushima monitoring well: reports

The operator of Japan’s stricken Fukushima nuclear plant on Monday said that groundwater from an observation well near the site of a leaky storage tank showed high levels of radiation, according to reports. The finding means that it “now seems more likely” that radioactive water from leaking tanks had mixed…

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…
