TEPCO is now only measuring temperatures outside of the reactors.
The utility also needs to prove that recriticality cannot occur, instead of avoiding the topic.
Naitoh said that TEPCO is now only measuring temperatures outside the reactors.
But he said that it needs to be confirmed through simulation that temperatures inside have fallen below 100 degrees.
He said it also must be proven that there are no risks of a recurrence of nuclear reactions, even though such possibilities are low.
The government and TEPCO plan to start installing new devices at the No. 1, 2 and 3 reactors next week to extract contaminated gases and reduce the release of radioactive substances.
