Recently the media has been talking about meltdowns at 1 or more of the reactors at the Fukushima No 1 nuclear power plant. Specifically, a partial or full meltdown of reactor 1 has been confirmed, and partial or full meltdowns at reactors 2 and 3 are suspected. They still don't know because nobody has been inside reactor buildings 2 and 3 yet to have a look. Actually, today for the first time workers ventured into reactor building 2, to be beaten back by high levels of ... steam.
So in any case it looks like damage to the fuel rods in all three reactors has been greater than feared.
Perhaps I am yet again going against the grain of puclic opinion when I express the opinion that this is very good news. There have been meltdowns in all three reactors ... and nobody noticed! The meltdowns happened in the first few hours and days after the tsunami, before cooling had been restored to the plant, and resulted in the relatively high radiation emissions that were recorded at the time. So basically, the worst thing that could possibly have happened happened...yet nobody was harmed by radiation. No injuries, no deaths. And since then things have inexorably improved...
To me, this is yet more evidence that the danger of radiation from the accident at Fukushima has been massively exaggerated.
