we asked nhk leading congressmen at a timer, noriyoki mizuno, what he had to say. here's what he had to say. >> translator: it's not in a critical condition, but close monitoring must continue to avoid criticality. mounted uranium fuel is believed to be scattered everywhere in the number 2 reactor in the containment vessel. a neutron ray may be causing nuclear fission from time to time. so long as this reaction is localized and temporary, there's no need to worry about, but this time the location of melted fuel or amount of water inside is believed to be creating a condition suitable for continuous nuclear fission. having said that, there's no change in the temperature of pressuring the containment vessel. tepco is pouring boric acid solution to suppress nuclear fission, so it's unlikely the huge amount of radioactive substances will be released from the reactor. government has been saying it aims to achieve a state of cold shutdown by the end of the year. it means bringing the temperatures inside the reactor under 100 degrees celsius with the release of radioactiv
