Steam found coming up from the top of reactor3 again / Reason is not verified yet

Fukushima Diary reported steam was found coming up from the top of reactor3 on 9/17/2013.

(cf, [Steam after typhoon] “Steam” observed from the top of reactor3 again / humidity was only 53% [URL])

According to Tepco, the “steam” was observed coming up from the same location of reactor3 around 8AM of 9/18/2013 again. It wasn’t seen by 10AM.

In the secretariat meeting for Fukushima decommissioning on 8/29/2013, Prof. Yamana from Kyoto University Research Reactor Institute stated Tepco needs to investigate what is actually discharged as the “steam” such Tritium. However, no analysis data has been published yet.

(cf, Kyoto Uni Prof. “Tritium might be discharged directly from the reactor3 to the atmosphere” [URL])



You can ignore the truth but the truth won’t ignore you.

Le réacteur 3 fume encore de la “vapeur” par son sommet : La raison n’en est toujours pas établie


Le Fukushima Diary a rapporté que la “vapeur” sortait à nouveau du haut du réacteur 3 le 17 septembre dernier. (cf. [Vapeur après typhon] La “vapeur” est à nouveau vue au sommet du réacteur 3 : L’humidité n’était que de 53 %)

Selon Tepco, le 18 à 08:00, la “vapeur” était à nouveau observée sortant du même endroit réacteur 3. On n’en a plus vu vers 10:00.

Le 29 août 2013, à la réunion du secrétariat pour le démantèlement de Fukushima, le Pr. Yamana de l’Institut de Recherche sur les Réacteurs de l’Université de Kyoto avait affirmé que Tepco devait chercher ce qui sort en fait sous forme de “vapeur”, en particulier le tritium. Or, aucune donnée analysée n’a encore été publiée. (cf. Un Prof. de l’Univ. de Kyoto : “Du tritium peut être directement disséminé dans l’air par le réacteur 3″)

Vous pouvez ignorer la vérité mais la vérité ne vous ignorera pas.

  1. The disaster hit on March 11, 2011, not March 11, 2013 as your report states in several places. You may want to amend that, there are too many people ignorant of this subject right now.
    Thanks for keeping us informed.

    1. No correction is required by Iori, and you should probably be a bit more thorough prior to leveling such accusations. The EXPLOSIONS in (pipe-failure) FDU-1, (MOX Fuel) FDU-3 & FDU-2, in that order, occured in 2011.

      The Steam is still rising TODAY from the FDU-3 ruins. The TEPCO assured-promised ‘cold shutdown’ notwithstanding.

      Some of the Fukushima groundwater is radioactive enough to glow in the dark. Typically, when an experimental facility continues to increase in radioactivity, we refer to that as a ‘breeder reactor’. It appears possible that the ENTIRE FDNPP may have evolved into an open air ‘breeder reactor’.

      This is NOT a good thing.

  2. I have taken another look at the explosions on 3/11 a few times on Youtube recently.

    One is defintely a hydrogen explosion, the others I am not so sure.

    One blast looks more like a steam explosion to me – the sort you would expect from a pressure cooker where the lid blows off and the debris goes straight up i thew air but there are no flames to speak of.

    The timeline looks to me like:

    Earthquake – Cooling Stops – Fuel melts dwon to bottom of pressure vessel – Water injected – Steam created – Intense Pressure – Steam Explosion – Open Pressure Vessel now more an spent fuel pool than an enclosed reactor – Regular steam seen rising from opening.

      1. Wasn’t the explosion at unit 4 blamed on hydrogen leaking from unit 3?

        Why? It was the only way to explain how a reactor with no fuel could blow up.

        1. Spent Fuel Pool Fires can cause secondary hydrogen (deflagration) explosions.

          The reported periodic loss & restoration of Spent Fuel water injection is consistent with melting of fuel and zircalloy. Wet-dry-wet-dry cycles are consistent with conditions for zircalloy to catch fire. The freshest fuel bundles in the Spent Fuel Pools still had lots of decay heat. Water will NOT extinguish a zircalloy fire; the water itself serves as an oxygen source.

          The released hydrogen from such underwater zircalloy fires can migrate to a collection trap, and achieve stoichiometric explosive proportions with the ambient oxygen. So there ARE multiple mechanisms for Unit-4 hydrogen explosions, even with the reactor shut-down, empty, open and full of nothing but cold water.

  3. F-F-F

    The Fukushima Daiichi Nuclear Power Plant containment architecture; clearly FAILED the 311 Test. Reactors – Grade F: (Three for Three), MetalContainment Shell – Grade F: (Also 3-4-3), Containment Concrete structures – Grade F: (3-4-3), Concrete Foundations – (preliminary) Grade F (Pending Final Review).

    An INTENSE lobby campaign in the USA, has materially contributed to a response delay; to the ongoing Fukushima Nuclear Disaster. So for example, SOME Americans once considered Richard A. Muller, Ph.D. to be a reliable and credible nuclear information source. Muller PRESUMED to instruct future USA Presidents on nuclear (not nuke-uler) physics. I personally have some misgivings and concerns about the candor and scientific objectivity of Dr. Muller, as illustrated below.

    http:// online wsj com (/article/SB10000872396390444772404577589270444059332) html ‘The Panic Over Fukushima’ by Dr. Richard Muller, Ph.D., professor of physics at the University of California, Berkeley.

    “Looking back more than a year after the event, it is clear that the Fukushima reactor complex, though nowhere close to state-of-the-art, was adequately designed to contain radiation. New reactors can be made even safer, of course, but the bottom line is that Fukushima passed the test.”

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.
