  • In February 2017, TEPCO released images taken inside Reactor 2 by a remote-controlled camera that show there is a 2-meter (6.5 ft) wide hole in the metal grating under the pressure vessel in the reactor's primary containment vessel, which could have been caused by fuel escaping the pressure vessel, indicating a meltdown/melt-through had occurred, through this layer of containment.

  • Since 2007, there have been at least 35 reported leaks, spills or other accidental releases in Illinois of water contaminated with radioactive tritium, a byproduct of nuclear power production and a carcinogen at high levels, a Better Government Association review of federal and state records shows. (thesouthern.com)
  • The recent leaks echo the controversy in 2006 when it was revealed that leaks at Braidwood over many years spilled 6 million gallons of radioactive water, some of which found its way onto private properties and at least one private drinking well. (thesouthern.com)

  • Exposure to iodine-131 presents a high risk in the immediate aftermath of a nuclear accident owing to its short half life of 8 days, making it intensely radioactive. (counterpunch.org)
  • Another consideration - which the authors do not enter into - is the effect of the other radioactive species emitted in the accident including 17.5% Caesium-137 and 38.5% Caesium 134. (counterpunch.org)
