TOKYO, KOMPAS.com - The Japanese government throwing more than 10,000 tons of contaminated water into the low-level radiation in the Pacific Ocean on Monday (4 / 4). This is done to stabilize the Nuclear Power Fukushima Daiichi problematic.
The Government of Japan with Tokyo Electric Power Company (Tepco), nuclear power plant operator, had been struggling to prevent leakage of radiation to pour thousands of tons of water to cool the reactor core that is too hot. This effort to make water that is splashed became highly radioactive.
Overflow of water with high radioactivity was deter officers reactor refit, has even leaked into the soil and the sea. Therefore, Tepco must empty the ponds containing water with low radioactivity to accommodate the overflow of water is highly radioactive.
Tepco convincing, disposal of water which are sufficient to meet the four Olympic-size swimming pool was not to endanger life at sea. Radiation level of water being dumped into the sea carrying about 500 times the normal limit.
When it announced the disposal, Tepco spokesman apologized to the people of Japan. "We have caused great difficulties for local residents. We can not express how deeply sorry we do this, "he said.
Cabinet Secretary who serves as spokesman for the Government of Japan, Yukio Edano, adding, "We have no choice but to dispose of radioactive contaminated water into the sea as a security measure."
Tepco explains, efforts to cool the reactor core to make the highly radioactive water accumulated in the turbine building, especially in the Unit 2 reactor. "Disposal of water in storage ponds is very urgent to accommodate this additional water," the statement Tepco.
Radiation contamination has been found in air, soil and water around nuclear power plants. In smaller concentrations were also found vegetables, milk, meat, shiitake mushrooms and final radiation contaminated.
Workers use white salt solution to track leaks of radioactive water into the sea. Cracks in the underground tunnel for treatment that was found late last week confirmed that radioactive water had leaked into the surrounding environment.
The leak confirms the main difficulties NPP recovery efforts, namely radioactive water pooled around the reactor and prevents workers to recover the cooling system.
Present crisis recovery efforts helped engineer 1000 General Electric Company (GE) of the United States, who designed the six reactors at the Fukushima Daiichi.
Director of GE's Jeffrey Immelt in his visit to Japan said its engineers worked together to analyze the problem. Immelt also offers assistance to overcome the power shortage due to damage to a number of nuclear power plants. Japan predicted shortage of 10 million kilowatts at least next summer.
Protest
Japan's nuclear crisis has triggered protests and rejection of the world toward the use of nuclear energy. Claims that appear to question the security and safety of nuclear power plants.
Head of the International Atomic Energy Agency (IAEA), Yukiya Amano in nuclear security conference attended by 72 countries in Vienna, Austria, Monday, reminded the participants that this concern underestimate the industrial sector. "We can not run the approach of 'everything is working as usual'," he said.
Amano said the crisis in Japan, a major challenge and has broad implications for the utilization of nuclear energy. "Concerns about the security of millions of citizens of the world's nuclear energy should be taken very seriously," he said.
Amano said, the end of last year more than 60 IAEA member states to plan the utilization of nuclear energy. However, the nuclear accident in Fukushima make them reconsider this plan.
Germany announced it would close the old reactor, while Switzerland and China to delay new reactor licenses. Taiwan is studying to reduce their dependence on nuclear energy. (AP / AFP / WAS)
