Gundersen: Very visible steam at Fukushima Unit 3 is from constant radioactive releases — Coming from hot rubble, not related to new explosion

Fairewinds Energy Education, Jan. 1, 2014: [...] the Internet has been flooded with conjecture claiming that Fukushima Daiichi Unit 3 is ready to explode. Fairewinds Energy Education has been inundated with questions about the very visible steam emanating from Fukushima Daiichi Unit 3. [...] Hot water vapor has been released daily by each of the four Fukushima Daiichi nuclear power plants since the accident. We believe that is one of the reasons TEPCO placed covers over Daiichi 4 and 1. [...] radioactive rubble (fission products) was left in each unit [...] heat from this ongoing decay of radioactive rubble is constantly releasing moisture (steam) and radioactive products into the environment. [...] [Unit 3] is still producing slightly less than 1 megawatt (one million watts) of decay heat [...] it is creating radioactive steam [...] hot radioactive releases [...] have occurring [sic] for the entire 33 months [...] The difference now is that the only time we visibly notice these ongoing releases is on the cold days [...]
The Ecologist reported on this unsubstantiated rumor which was then used as a source by ‘Gizmodo. The Ecologist has now changed their original report without any notice or explanation.Here’s the original ending: “The Turner Radio Network is advising people on the West Coast of North America to”prepare for the worst” in case a meltdown of the waste fuel is in fact commencing. No official warnings have been released on either side of the Pacific.”
Here’s how it ends now: “According to a Fairewinds Energy Education posting on Facebook, the reactor is currently producing about 1 MW of heat, equivalent to 1,000 1KW electric fires, so enough to produce plenty of steam. This would provide the least worrying explanation for the steam, in that as the radioactivity continues decline so will the heat production and the volume of steam produced. If this explanation is correct, there is no reason expect any catastrophic outcome. However the steam is carrying considerable amounts of radiation into the atmosphere and represents an ongoing radiation hazard.”
