Another substantial part of the evacuation area in Fukushima prefecture has been recategorised, with most of Iitate village subject to conditional returns from tomorrow.
Tepco has published further measurements showing that the used fuel pool at the damaged reactor building of unit 4 at Fukushima Daiichi is not tilting and would be able to withstand a large earthquake.
The latest analysis has upped the figures for the amount of radioactivity released during the accident at Fukushima Daiichi, although the estimate for the main long-term contaminant, caesium-137, was actually reduced.
The torus suppression chamber of Fukushima Daiichi 2 appears to be intact, ending speculation that it ruptured during the height of the accident sequence.

Newly released pictures of the tsunami impact at Fukushima Daiichi show the strength of the wave and the last-minute escape of a ship from the power plant's breakwater area.
Tepco workers have dealt with a temporary loss of cooling systems at Fukushima Daiichi unit 4's used fuel pool. Meanwhile, Japan's first reactor to restart after the Fukushima accident has reached criticality.
A new cover has been installed over the used fuel pool of unit 4 at the damaged Fukushima Daiichi nuclear power plant. The cover will provide additional protection from the weather and prevent debris from the roof of the reactor building falling into the pool.
Breakdowns in communication caused extra confusion and contributed to the distress of residents evacuated from their homes following the Fukushima Daiichi nuclear accident, a survey carried out for the Japanese Diet has revealed.
