(Reuters) - One of the reactors at Japan's crippled Fukushima nuclear power plant has a hole in its main vessel following a meltdown of fuel rods, leading to a leakage of radioactive water, its operator said on Thursday.
The disclosure by Tokyo Electric Power Co (TEPCO) is the latest indication that the disaster was worse than previously disclosed, making it more difficult to stabilize the plant.
The discovery of the leak provides new insight into the sequence of events that triggered a partial meltdown of the uranium fuel in the No. 1 reactor at Fukushima after the plant was struck by a massive earthquake and tsunami on March 11, officials said.
The battle to bring Fukushima under control has been complicated by repeated leaks of radioactive water, threatening both the Pacific Ocean and nearby groundwater.
Workers at the Fukushima Daiichi nuclear plant have been pumping water into at least three of the six reactors on the site to bring their nuclear fuel rods to a "cold shutdown" state by January.
But after repairing a gauge in the No. 1 reactor earlier this week, TEPCO discovered that the water level in the pressure vessel that contains its uranium fuel rods had dropped about 5 meters (16 ft) below the targeted level to cover the fuel under normal operating conditions.
"There must be a large leak," Junichi Matsumoto, a general manager at the utility told a news conference.
"The fuel pellets likely melted and fell, and in the process may have damaged...the pressure vessel itself and created a hole," he added.
"TEPCO seems to be going backwards in getting the situation under control and things may well be slowly eroding with all the units having problems," said Tom Clements with Friends of the Earth, a U.S.-based environmental group.
"At this point, TEPCO still finds itself in unchartered waters and is not able to carry out any plan to get the situation under control," he said.
Yeah I read basically that. It sure does complicate things. Got a friend in Japan, a native, and get general reports somewhat regularly. He has friends helping in the general disaster zone and said it's very bad.Tepco is now confirming the Reactor 1 has fully melted down.
I think it's time the USA extends a gracious invitation for all the Japanese women to come and live here
(Dow Jones) - Giant polyester covers will soon be placed around the damaged reactor buildings at Japan's Fukushima nuclear complex to help contain the release of radioactive substances into the atmosphere, the plant operator said Friday.
Tokyo Electric Power Co. (TEPCO) will install the first cover at the No. 1 reactor, the focus of recent stabilization efforts, starting next month.
Workers will erect a steel framework and place a giant polyester tent-like cover around the reactor building. Similar covers will be placed around units No. 3 and 4. The work is expected to be completed by the end of the year.
A series of hydrogen explosions blew off the roofs and upper walls of the three reactors in the days after the March 11 earthquake and tsunami knocked out their cooling systems, triggering the overheating of the reactors.
i follow this kat on youtube who reports whats happening in Japan, stuff there news agencies wont let out....
yesterday he was repo
rting that Japanese officials are going to the infected areas and killing every single animal with a shot to the face, all livestock, cats or dogs.....
imagine your a dog, haven't seen a human or got food in over a month, you see one and you rejoice! help is here! im saved!!! then BAM!!! shot in the face.....
Dang.. that's crazy. I wanna watch, whats the guys YouTube name, or link?
