In Japan, engineers have managed to restore power at the tsunami-stricken Fukushima nuclear plants which is vital to reactivate the crippled cooling system of the overheated atomic fuel. Tokyo Electric Power Company, TEPCO, which owns and runs the plants, said it has been able to connect power cables to the No 1 and No 2 reactor buildings so as to cool down the overheating spent fuel. It said, six workers have been exposed to high levels of radiation. Excessive radiation was also found in milk and spinach in Fukushima and Ibaraki prefectures. Yukio Edano, Chief Cabinet Secretary, told a press conference that the detected radiation was above Japan's regulated standards. However, he said it does not immediately pose a risk to human health.TEPCO said the No 2 reactor is expected to receive power today. Edano said the condition of the No 3 reactor has become relatively stable following the water discharge and that the authorities are now preparing to spray water into the No 4 reactor to cool its spent fuel pool.The accident severity level at the plant was raised from four to five on the 7-point international scale by Japan's Nuclear and Industrial Safety Agency, placing the crisis two levels below Ukrain's 1986 Chernobyl disaster.Meanwhile, a quake with 6.1 magnitude rocked Ibaraki Prefecture and its vicinity in the Kanto region and the Tohoku region at 6.56 pm local time. According to Japan Meteorological Agency, the quake was also felt in Tokyo and other metropolitan area.National Police Agency said, the number of dead and missing in the double disaster neared 20,000 — 7,653 deaths and 11, 746 unaccounted for. It said 3,090 bodies have been identified so far, of which around 1,550 have been handed over to their families.
