Current condition of Fukushima Daiichi Unit 4

TEPCO has worked feverishly to remove the upper crumbling pieces of the reactor building atop of Reactor 4.

The head of a Diet-appointed panel to investigate the Fukushima Daiichi nuclear power plant disaster said Friday that the crippled plant in northeastern Japan remains in a dangerous situation because of its fragile structure.

“Fukushima remains at a very high risk, not only because of the spent fuel issues, but also because of its fragile structure,” Kiyoshi Kurokawa, also professor emeritus at the University of Tokyo, told a press conference at the Foreign Correspondents’ Club of Japan, noting that another huge earthquake like the one last year may occur off the coast of northeastern Japan again.

When the Fukushima Daiichi nuclear disaster began on March 11th, 2011, Unit 4 was shut down and all fuel rods had been transferred to the spent fuel pool on an upper floor of the reactor building.

On March 15th, an explosion damaged the fourth floor rooftop area of the unit 4 reactor.
