Akhir 23, 1432 / March 28, 2011, SPA -- Highly radioactive water has leaked from a reactor at Japan's crippled nuclear complex, the plant's operator said on Monday, while environmental group Greenpeace said it had detected high levels of radiation outside an exclusion zone, according to Reuters. Reflecting growing unease about efforts to control the six-reactor Fukushima Daiichi complex, plant operator Tokyo Electric Power Co (TEPCO) had appealed to French companies for help, the Kyodo news agency said. The plant, 240 km (150 miles) north of Tokyo, was damaged in a March 11 earthquake and tsunami that left more than 28,000 people dead or missing across northeastern Japan. Fires, explosions and radiation leaks have repeatedly forced engineers to suspend efforts to stabilise the plant, including on Sunday when radiation levels spiked to 100,000 times above normal in water inside reactor No. 2. A partial meltdown of fuel rods inside the reactor vessel was responsible for the high levels, although Chief Cabinet Secretary Yukio Edano said the radiation had mainly been contained in the reactor building. -- SPA
