As Japanese officials report that radioactive water has contaminated the ground near the damaged Fukushima nuclear power plant, concerns grow that it may take several more weeks to get the reactors under control.
Given the severity of the earthquake and tsunami that devastated Japan, the plant operators at Japan’s damaged Fukushima power plants are being forced to improvise solutions as they attempt to bring the reactors and radiation leaks under control.
A radiation leak in the turbine building of Fukushima's Daiichi unit 3 reactor, damaged by Japan's earthquake and subsequent tsunami, suggests there is some chance the reactor core has been breached.
A reactor core may have been breached at one of Japan’s Daiichi reactors. For a nation still mobilizing to respond to a triple crisis – the earthquake, tsunami, and nuclear reactor crisis – this dangerous development is difficult to address.
Reports of increased radiation levels in the turbine room of Japan’s damaged nuclear reactor in Fukushima have increased concerns that damage has been done to the steel container that encloses the nuclear core.
The situation at Japan’s damaged nuclear plants in Fukushima remains volatile and dangerous, as workers struggle to control radiation leaking from the reactors and cool the nuclear cores.
The incident at Fukushima has reminded Japan that a serious accident in an advanced country can happen at any time. While Japan should reassess how dependent upon nuclear power it should be in the longer term, the Fukushima accident is not a blanket verdict against its use.
As the crisis progresses at Japan's Daiichi nuclear reactors in Fukushima, authorities are struggling to determine the extent of radiation released and its health effects and to decide if and when the reactors should be entombed.
While the Fukushima reactor crisis, resulting from Japan's devastating earthquake and tsunami, remains unresolved, some positive developments have been made. The possibility of spent fuel pools overheating is now the main source of concern.
As power is being restored to the Fukushima nuclear reactors, which were severely damaged by Japan's recent earthquake and tsunami, crucial questions remain about whether the cooling system will be functional and the likelihood of further radiation leaks.
