Xenon can’t be caught by filter,what did they measure ?

Though Iodine 131 has been measured at variety of locations in Japan to show Fukushima went back to recriticality state,
it was the first time for Tepco to admit that reactor 2 has gone back to recriticality today.

Cf,a very insightful comment to the blog.

There’s no I-131, it’s all decayed, disappeared, gone. The Lab must be worng

At their press conference of 11/2/2011 AM, Tepco admitted there is the possibility that reactor 1 and 3 may be in recriticality as well.

The Nuclear Agency describes it as “temporary spontaneous fission”, but Tepco clearly admitted that there has been “small” recriticality on and off since months ago, they noticed the fact finally because they checked the filter on 10/28/2011.

This time, Tepco sounds more honest than The Nuclear Agency.

However, their explanation does not make sense as always.

1) There is no filter at reactor 1 and 3. How do they know they may be in recriticality to measure xenon 133 and 135 ?

2) Xenon is noble gas,which can hardly be caught by a filter.What did they think they caught on the filter ? Why did they quit deceiving us all of a sudden ?

3) They explained they are injecting boric acid to the container vessel,but there is no container vessel. Where are they trying to inject it ?

JP PM Noda flew to France this evening.


No wonder, it is time to abandon this country,like Noda.


About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
