Japanese nuclear security officials said Friday that they believe that the reactor core at one unit of the anxious Fukushima Dai-ichi nuclear power plant may have smashed, raising the opportunity of more severe contagion to the surroundings.
"It is probable that anywhere at the reactor may have been hurt," said Hidehiko Nishiyama, a spokesman for the nuclear safety society. But he added that "our data put forward the reactor retains certain suppression functions," imply that the spoil may have occurred in Unit 3's reactor core excluding that it was inadequate.
Officials say the injure could in its place have happened in other gear, including piping or the spent fuel pool.
Workers have been harassed to keep cool water around radioactive fuel rods in the reactor's heart after the March 11 earthquake and tsunami cut off power deliver to the plant and its cooling system.
