TOKYO - Japan said Monday it will stabilize and shut down its nuclear power plant disaster in six to nine months, as expected, as residents of the two cities most around her were evacuated in accumulated radiation concerns.

Chronology of the Government to stabilize the factory has been called into question last week after new data showed that damage to a reactor at the Fukushima Dai-ichi nuclear complex were worse than expected. That assessment also encouraged the Government to recognize that the reactor fuel rods had mostly melted shortly after the earthquake on March 11 and the tsunami failure of cooling plant system.

Until the reactors are shut down, they continue to leak radiation, but many more small quantities in the early days of the disaster. However, the volume of contaminants spread plant- and their accumulation in places outside the area of 12 miles (20 kilometres) of evacuation - convinced the Government to residents of the order to leave the cities more end of April. Some of these evacuations began this weekend.

In a rare bit of good news, the authorities said Monday that their chronology original to stabilize the reactors is possible because the temperature in the heart of the unit 1 reactor has fallen to almost 100 Celsius (212 F)a level deemed safe and close to a cold case.

"We believe that we can keep us during the term," said Goshi Hosono, assistance from the Prime Minister and Director of the task force nuclear crisis, referring to the timetable established in April to bring the troubled reactors three factories at a stop cold and stable of six to nine months.

"What is crucial is how we can proceed with cooling.". Even if the core had melted, they are somewhat kept cool, "said Hosono.

The plant, operated by the Tokyo Electric Power Co., is still escape a large amount of contaminated water - that one of the many problems faced by workers who tried to bring under control the past two months.

Plan of workers plant to pump water highly radioactive swelling within the engine 3, construction of a makeshift storage unit. TEPCO has taken a similar step with water contaminated by an another reactor after a massive leak in the Pacific in April triggered criticism in and out of the Japan.

Monday, the operator has released data from the first hours of the crisis for the first time, to comply with a request of the Government. Spokesman Junichi Matsumoto TEPCO said nothing indicated that the earthquake caused parts of reactor key or equipment damage, confirming the story that the tsunami has been the cause of the crisis.

Hosono said Monday that a similar collapse had probably been units 2 and 3 as they were both out of the water for more than six hours after the power outage on March 11. 1 Unit reactor core was out of the water for more than 14 hours, he revealed Monday.

Most of the unit 1 fuel melted and collapsed at the bottom of the pressure vessel which cements the sticks, and some who ate in the vessel and monitor into a large beaker-shaped containment vessel, officials said.

TEPCO said Monday there was no indication of the preliminary data published early plant in the early hours of the crisis, for the first time since the disaster, but denied that there was no early indication of damage to the key partiesincluding speculation ducts,

During this time, approximately 50 residents of Kawamata and 64 of Iitate left their homes during the weekend and began to adapt to life in evacuation centers after leaving their homes over the weekend on the orders of previous Government.

Approximately 6 700 people remain in the two areas and are expected to leave at the end of June.

Cities are one of several that were recorded but relatively high radiation readings which are outside of a previous 12 miles (20-km) area of evacuation of radius around the nuclear power plant.

At the end of April, the Government said residents in these areas should be prepared to evacuate in the months ahead due to concerns about cumulative radiation.

Officials in Iitate said they want to have most of the residents of the city were evacuated at the end of the month. The picturesque, rural village has a population of 6 500 before the earthquake and about 2,000 people have already moved voluntarily.

On Sunday, four families with babies or pregnant women left the city, according to an Iitate official who did not give his name because he was not allowed to speak to the media.

He said that it is difficult to estimate how many people rest, in the city because many to evacuate on their own and the village has no details on their situation.

Officials have said that they have not set an exact date for final evacuations because some residents may have improperly leaving - because they are owners of livestock or for other reasons - and may require additional time.

While the Japan worked to move people away from the factory, the United States more relaxed some of its advice to its citizens in the Japan - which has been more rigorous than Tokyo.

Washington has recommended that Americans remain at least 50 miles (80 km) of the plant, but an alert to update trip Monday, said that it was safe for people in transit on this area using a road and rail line.
