Fukushima might make 2020 Tokyo Olympics impossible' 福島事故により2020東京オリンピックは実現しえないだろう。

There is no reason to believe that radiation leaks at Fukushima will be contained by 2020, so the Tokyo Olympics can become impossible, nuclear technology historian Robert Jacobs told RT.
Last August Tokyo Electric Power Company (TEPCO) for the first time requested international help in its increasingly desperate fight to contain the leaks at the crippled nuclear plant. Historian of social and cultural aspects of nuclear technology and Associate Professor at Hiroshima Peace University, Robert Jacobs believes this means the problem is catastrophically large.

Robert Jacobs: The main thing it tells us is that they are so significant and so large that the Japanese government and Japanese nuclear industry is at a loss at how to deal with them. Now remember Japan has over 50 nuclear power plants, so there's a lot of expertise and a lot of experience in Japan. If these leaks are so significant that the Japanese nuclear industry and government are at a loss of how to deal with them then they are catastrophically large. So this is a very, very big problem and it's not an easy problem to solve.

RJ: Clearly the countries that would be the most useful are the countries with the largest and oldest groups of power-plants, so this would be the United States, Russia and also the United Kingdom or rather France. These are the countries with the largest amount of nuclear power plants in the world and the longest amount of experience, so these are countries that have both expertise and experience.

So part of the expertise that Russia has shown in dealing with Chernobyl is to evacuate a much larger area and move people further away from the contamination. This is not being done in Japan. But this won't solve the problems of the leaks and this won't solve the problems of the contamination.

RT: How could all this affect the 2020 Tokyo Olympics?
RJ: It could be very devastating for the Tokyo Olympics. Right now there is still all throughout northern Japan caesium being found in the urine of children there which means that the exposure and contamination is ongoing, they have not gone down for children in these areas, they are still being exposed to radiation. So two and a half years later it has yet to be contained. There is no reason to believe that it will be contained even by 2020. …...... As we know there is a spent fuel pool in the number 4 reactor that holds an immense amount of spent nuclear fuel rods and the building has been damaged and is leaning. This spent fuel pool is several floors up, so if this building were to collapse which could happen it would spill these spent nuclear fuel rods all over the ground which would make the 2020 Tokyo Olympics impossible and could threaten all kinds of health problems throughout northern Japan and Tokyo itself. So it's a wish that Tokyo Olympics will not be affected by this, but there's no doubt that the radioactive leakage will be continuing at that time.
