– Damaged fuel rods are cracked and leaking radioactive gases in Fukushima Unit 4 pool; Wire appears trapped in racks — Another assembly bent when “mishandled during a transfer” (ENENews, Nov 14, 2013):
Japan Times, Nov. 14, 2013: Earlier this week, Tepco found three damaged assemblies that will be difficult to remove, but officials said the damage appeared to have occurred before the March 11 disasters.
Reuters, Nov. 14, 2013: One of the assemblies was damaged as far back as 1982, when it was mishandled during a transfer, and is bent out of shape, Tepco said in a brief note at the bottom of an 11-page information sheet in August. In a statement from April 2010, Tepco said it found two other spent fuel racks in the reactor’s cooling pool had what appeared to be wire trapped in them. Rods in those assemblies have pin-hole cracks and are leaking low-level radioactive gases, Tepco spokesman Yoshikazu Nagai told Reuters on Thursday. […] Having to deal with the damaged assemblies is likely to make [removing the other fuel] more difficult […]
Tepco spokeswoman Mayumi Yoshida: “The three fuel assemblies … cannot be transported by cask […] We are currently reviewing how to transport these fuel assemblies to the common spent fuel pool,” she said.
