Tepco announced there are only 2 heating gauges which they think are not broken out of 40 heating gauges.
Though they have been criticizing that “meltdown” is a fear mongering term, Tepco states most of the heating gauges were damaged because of the heat (300~400℃) from meltdown.
There are 40 heating gauges in reactor2, but 1 has its wire broken, 33 have bad isolation performance to include 8℃ of error.
About the broken 33 heating gauges, they simulated the meltdown situation to test if they can stand with the heat.
Tepco states it’s impossible to put new heating gauges in the reactor.
However, NHK reported there are 40 heating gauges in reactor 2 ,where Kyodo reported there are 41 and broken ones are only 8.
Actually, 2 (correct ones) + 34 (broken ones) is 36, which is less than the total 40. NHK’s report does not make sense itself.
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.
