Some spent fuel rods at Fukushima were damaged before 2011 disaster

Three of the spent fuel assemblies due to be carefully plucked from the crippled Japanese nuclear plant at Fukushima in a hazardous year-long operation were damaged even before the 2011 earthquake and tsunami that knocked out the facility.

The plant's operator, Tokyo Electric Power Co, or Tepco, said the damaged assemblies - 4.5 meter high racks containing 50-70 thin rods of highly irradiated used fuel - can't be removed from Fukushima's Reactor No. 4 using the large cask assigned to taking out more than 1,500 of the assemblies.

Tepco is due within days to begin removing 400 tones of the dangerous spent fuel in a hugely delicate and unprecedented operation fraught with risk.

Having to deal with the damaged assemblies is likely to make that task more difficult and could jeopardize a 12-month timeframe to complete the removal that many have already called ambitious.
