Tepco is going to start removing the fuel assemblies from reactor4 pool next week. They will take 13 months to remove over 1500 fuel assemblies one after one, which is over 5,000 times much as Hiroshima bomb (based on Cs-137).They built 6 teams specially trained for this task. One team consists of 6 members. 1 member is from Tepco, but 5 members are from some other company, which Tepco conceals the name of and the reason of the concealment is also concealed. The removed fuel is to be carried to the common usage pool. It’s not clear what to do with the fuel assemblies after transferring to the common pool. Reactor4 spent fuel pool is covered with the crane building, so we cannot see the crane picking up the assemblies from live camera. What makes it more dangerous than the daily fuel removal is the fact that the pool is full of debris. They vacuum the small pieces of the debris over the assemblies but still it’s likely that the crane accidentally picks up a piece of debris when it grabs an assembly. In that case, it’s possible that the assembly is dropped. Tepco claims one assembly cannot reach the critical state. Even if it’s dropped on other assemblies, it wouldn’t affect the outside of the plant area. Tepco’s statement has always been correct. Even about the contaminated water issue, they announced it rains so heavily only once in ten years that the contaminated water tank dams overflow. Indeed, it overflowed every time a Typhoon hit Fukushima since this September. As the emergency measures, Tepco is to warn the people around the plant area by using transceiver. This would save everyone like they did in 311. The only thing we could do it to hope no earthquake to occur for the following 13 months. (It was just last week that M7.1 hit Fukushima.) Fukushima Diary will try its best to keep the eyes and ears on reactor4.
