Photostream : Emergency at another reactor of Japan's Fukushima nuclear power plant

13 Mar

Nuclear accident rated at level 4 : The Japanese government rates the accident at the Fukushima Number One nuclear power plant at level 4 on an international scale of 0 to 7. Two radioactive substances, cesium and radioactive iodine, were detected near the Number One reactor at the plant on Saturday. Their presence indicates nuclear fission of uranium. The Nuclear and Industrial Safety Agency said that fuel in the reactor partially melted. It's the first such accident in Japan. A level 4 on the International Nuclear and Radiologocal Event Scale includes damage to fuel and release of significant quantities of radioactive material within an installation. It's the same level as a criticality accident at a nuclear fuel processing plant in Tokai Village in Ibaraki Prefecture, south of Fukushima, in 1999. The agency called the accident very regrettable even though it was triggered by an earthquake. ( Photo : NHK)

Second Japanese Nuclear Reactor At Risk of Exploding : Nuclear safety agency says the cooling system has stopped working at the Fukushima number three reactor, VOA News reported on Sunday. Japan's nuclear safety agency says there is an emergency at another reactor at a quake-hit power plant. Japan's Nuclear and Industrial Safety Agency said Sunday that the cooling system at the number three reactor at the Fukushima nuclear plant has stopped working and risked a possible explosion following a blast Saturday at the plant's number one reactor. VOA reporters close to the plant say aftershocks are still rocking the area, more than 24 hours after the original 8.9-magnitude jolt and tsunami hit on Friday afternoon, local time. An explosion Saturday damaged a building housing the Fukushima facility's number one reactor, however officials say the reactor itself remained intact.Officials say radiation from the plant appeared to have decreased after the blast on Saturday. But authorities did not say why and the extent of the ongoing danger was not clear. Authorities had called on all residents to move at least 20 kilometers from the facility and as a precaution against radiation poisoning, authorities say they are distributing iodine tablets to people in the area.

In this video image taken from NTV Japan via APTN, smoke rises from Unit 1 of Fukushima Daiichi nuclear power plant in Okumamachi, Fukushima prefecture, Japan, Saturday, March 12, 2011. Japan’s Government spokesman Yukio Edano said the explosion destroyed the exterior walls of the building where the reactor is placed, but not the metal housing enveloping the nuclear reactor, however the government has ordered the evacuation of all people within a 12-miles (20 Km) radius of the plant. As reported by RIA NOVOSTI on Monday, Another reactor at Japan's Fukushima nuclear power plant has lost its emergency cooling system, international media reported on Sunday, quoting Japan's Nuclear and Industrial Safety Agency. Additional water supply to the Number Three reactor should be established urgently to avoid a blast due to overheating, an agency official told a news conference. On Saturday, a powerful blast hit the Fukushima Number One power station, about 250 km (155 miles) northeast of Tokyo, which was badly damaged by Friday's devastating earthquake and tsunami. The explosion destroyed the wall the reactor turbine building, but Japanese Chief Cabinet Secretary Yukio Edano said the reactor itself, covered with a steel container, was not damaged. In a report to the International Atomic Energy Agency (IAEA), the Japanese authorities assigned the accident at the Fukushima Number One power station the level 4 on the international INES scale that runs from 1 (anomaly) to 7 (major accident), the DPA news agency reported. According to the IAEA's definition, a level-4 accident is defined as having "local consequences," such as a "minor release of radioactive material." (AP Photo/NTV Japan via APTN)

In this photo released by Tokyo Power Electric Co., the Fukushima Daiichi power plant's Unit 1 is seen after an explosion in Okumamachi, Fukushima prefecture, Japan, Saturday, March 12, 2011. As reported by Kyodo News Agency on Sunday, Tokyo Electric Power Co. said Sunday another reactor of its quake-hit Fukushima nuclear power plants had lost its cooling functions, while at least 15 people at a nearby hospital were found to have been exposed to radioactivity. The utility supplier notified the government early Sunday morning that the No. 3 reactor at the No. 1 Fukushima plant had lost the ability to cool the reactor core. The reactor is now in the process of releasing radioactive steam, according to top government spokesman Yukio Edano. It was the sixth reactor overall at the Fukushima No. 1 and No. 2 plants to undergo cooling failure since the massive earthquake and ensuing tsunami struck Japan on Friday. The disaster raised fears over radioactive leaks from the plants after cooling systems there were hampered, most seriously at the No. 1 reactor. An explosion Saturday at the No. 1 plant blew away the roof and the walls of the building housing the No. 1 reactor's container. The government and nuclear authorities said there was no damage to the steel container housing the troubled No. 1 reactor, noting that the blast occurred as vapor from the container turned into hydrogen and mixed with outside oxygen.
