Yomiuri Shimbun translated by EXSKF, Nov. 12, 2013: On November 12, TEPCO disclosed that there were three fuel assemblies [...] in the Spent Fuel Pool of Reactor 4 [...] that were deformed and would be difficult to remove.
Fukushima Minyu translated by EXSKF, Nov. 13, 2013: According to TEPCO, one of the damaged fuel assemblies is bent at a 90-degree angle [literal meaning: bent in the shape of a Japanese character "く"; actual angle could be less]. It was bent 25 years ago when a mistake occurred in handling the fuel. The other two were found to be damaged 10 years ago; there are small holes on the outside from foreign objects.
Reuters, Nov. 13, 2013: [TEPCO] will as early as this week begin removing 400 tonnes of highly irradiated spent fuel in a hugely delicate and unprecedented operation fraught with risk. Carefully plucking more than 1,500 brittle and potentially damaged fuel assemblies from the plant’s unstable Reactor No. 4 is expected to take about a year [...] If the rods – there are 50-70 in each of the assemblies, which weigh around 300 kg (660 pounds) and are 4.5 metres (15 feet) long – are exposed to air or if they break, huge amounts of radioactive gases could be released into the atmosphere.
