Robots risky radioactivity detected in Japan

.- A pair of small robots sent to explore the interior of a damaged nuclear reactor in Japan came out on Monday with the discouraging news that the radiation is so high that it prevents the entry of workers to repair it. However, the authorities are hoping to meet his new "road map" to clean filtered radiation and stabilize the nuclear plant in Fukushima Dai-ichi end of the year, so that they begin to allow the return of tens of thousands of people evicted from their homes.

"I had hoped to high radioactivity in these areas," said Chief Cabinet Secretary Yukio Edan. "I'm sure (the company operating the Tokyo Electric Power Co. plant) TEPCO and other experts took into account such data when drawing up the itinerary." The nuclear crisis in northeast Japan, which is the worst in U.S.

history, was triggered by the earthquake and tsunami of March 11 that marred the cooling system in nuclear power station and caused overheating in the fuel rods. Authorities will need to redouble efforts to see the promise after announcing that escalated radiation in a vessel of Unit 2 and that contaminated water was found elsewhere in the plant.

Also for the first time presented a detailed description of damaged fuel rods in three reactors with problems, and said they had cast bars. That damage รข € "sometimes referred to as partial melting of a reactor €" had been provided on several occasions, but the confirmation, along with a persistent leak of radiation in other areas, can envision how it will be difficult and lengthy the healing process.

In fact, the same authorities have recognized the existence of so many complications that could extend his term. Irritation from what is considered a slow response to the nuclear crisis and natural disasters that caused it also appears in the parliament. Several lawmakers questioned the Prime Minister Naoto Kan.

"You should bow his head by way of apology," he snapped at Kan Masashi Waki legislator of the opposition Liberal Democratic Party. "I sincerely apologize for what happened," Kan said, insisting the government did everything it could to meet these unprecedented disasters. TEPCO president, Masataka Shimizu, seemed upset when he was confronted by legislators.

The plant workers have entered the reactor buildings from the early days after the cooling systems are spoiled. The hydrogen explosion occurred in units 1 and 3 during that time destroyed the roofs and covered with radioactive debris. While the government said Sunday that the proposed deadline was unrealistic, people who fled their homes, their jobs and farms expressed frustration at the time you have to stay away.

"Well, this year is lost," said Kenji Matsueda, of 49, who lives in a refugee center in Fukushima after being forced out of their home located 20 kilometers (12 miles) from the plant. "I have no idea what will. Nine months is too long. And it could be much more. I think even they know it." After receiving an order from Prime Minister Kan, for the first time since the disaster TEPCO released a plan explaining their long-term strategy to contain the crisis that has created a sense of fear throughout the country.

"We sincerely apologize for the problems caused" , Katsumata said. "We are doing everything possible to prevent the crisis from deteriorating further." Among its plans, TEPCO will handle the crisis in two stages. In the first, the company will focus on the cooling system of the reactors and spent nuclear fuel ponds, as well as reducing the level of radioactive leakage.

Also try to decontaminate the area and the atmosphere. In the second, aims to control drastically the release of radioactive materials, shut down the reactors and temporarily cover the buildings.
