Japan will begin discussions earlier than originally planned on redefining which areas are subject to evacuation orders.
Such discussions became feasible on Monday when the government and Tokyo Electric Power Company, at their monthly progress review, revised their timetable for bringing the nuclear crisis under control.
According to the revised plan, the second stage, involving a state of cold shutdown of the reactors at the Fukushima Daiichi nuclear power plant, will be achieved by the end of this year, one month earlier than originally targeted.
The revised timetable says temperatures around the Numbers 1, 2, and 3 reactors are less than 100 degrees Celsius, and that the amount of radiation being emitted has dropped to about 100 million becquerels per hour.
This is about one 8-millionth of the level when the crisis began, and about half that of a month ago.
It also says additional radiation exposure in areas just outside the plant is estimated at 0.2 millisieverts per year at the most.
But many problems remain, as the government has yet to announce the details of the decontamination work that must be done in areas affected by the evacuation orders.
