Fukushima Daiichi update 7/19/2013

Tokyo Electric Power Company has reported the cessation of the "steam like emission" from the upper level at Fukushima Daiichi Unit 3.  The utility also reports no deviation from established norms in terms of airborne contamination.

Yesterday I reported that TEPCO officials had remarked to various Japanese press outlets that it was their suspicion that rainwater had contacted the head of the primary containment vessel, and the resultant vapor rising through the structure was what the contractor had videotaped.  That suspicion has now been put officially into print in the latest overall Fukushima Daiichi daily plant status update.  See the underlined portion of the report.

All this said, it would not be surprising at all for such an event to happen again while the 1F3 reactor building is still exposed to the elements - thus perhaps auguring future occurrences of similar nature.  TEPCO cannot however ignore any such future events (it must analyze any suspect emission) and I'd expect their response in future to mirror that we've seen over the last couple of days.

  1. It is truly astonishing that something as trivial as rain water vapour rising from a building can get the paranoid delusionists literally screaming that the end of the world is nigh.

    The most significant problem with Fukushima is simply the hysteria surrounding the place.

    If an explanation is offered then you get accused of lying. If you ignore it because it is trivial you get accused of a cover up. This sort of farce must seriously impact the clean up schedule.

    Truly a no win situation for the engineering staff.

  2. The Japanese media could squash such rumors and bogus reports in a pinch -- if they were as fair and thorough as the journalistic ethics and honor they swore by, which I guess makes them royal hypocrites here. All my sympathy and spiritual support to whatever pro-nuclear outlets or blogs there are in Japan! Keep up the faith and chins!
