Explosion at nuclear plant Marcoule

  1. Sep 12, 2011 #1
    Explosion in a nuclear plant in France, no details yet. Hope it is nothing bad...

    Re: Japan Earthquake: nuclear plants

    To clarify: there are no working reactors at http://en.wikipedia.org/wiki/Marcoule, and looks like the explosion was not related to nuclear energy. Still, as they process radioactive waste, contamination is possible.

    80 nSv/h is 0.7 mSv/year, slightly below natural background levels (assuming they average at about 3 mSv/year).

    http://www.irsn.fr/FR/Actualites_pr...ation_installation_CENTRACO_Marcoule_12h.aspx the accident took place "around 12 noon" on 12 September. The cause of the explosion is still unknown. They took grass samples "within hours after the accident", from which a preliminary laboratory analysis "confirmed the absence of artificial radionuclides". 3 samples have already undergone a 12 hour counting. The other 2 samples have not finished the 12 hour counting.

    There have been no updates for air measurements since 11:50 on the 12th.

    Why would they say that they update every 4 hours and then not update for nearly 48?

    That is what I would like to know.

    In the last (August) issue of "magazine Repères" they say, about the follow-up of radiations on the French territory during the Fukushima crisis

    So, one possibility is that they intended this 4 hour update speed only for the Fukushima crisis. Now that the Fukushima crisis is over, they might get back to the 24 hour update speed. Yet that would not explain why their website has not been updated for more than 48 hours by now.

    Even the 4 hour update speed is very low compared to the equivalent Japanese website, http://www.bousai.ne.jp/vis/index.php [Broken] which provides updates every 10 minutes.

    Why can't the French authorities be as transparent as the Japanese authorities and provide the real time data ?

    Also the number of monitoring posts seems to be low. Around Japanese power plants there are 5 or 6 monitoring posts. On the Marcoule map above we can see only two monitoring posts, one in the north and one in the south of the plant. What happens if the wind goes west or east ?

    Also the website saturation problem does not seem to have been solved as I failed from connecting to that website one or two hours after the Marcoule accident began being reported in the news. Although a minor one, this is one lesson from the Fukushima crisis which has not been learnt. They seem to be comfortable with having a website that gets saturated when people need it, instead of apologizing to the internet users that were affected.

    Apparently they are not reporting because there is nothing signifiant to report. They plan an investigation.

    Normally the process is to chemically decontaminate metal equipment (valves, pumps, piping, tools, . . .).

    17Bq/kg? That's not waste, it's good clean food. We've got food in Japan that's measuring over 4,000 Bq per kg.

    France will be fine so long as they keep stopping the Japanese tea in customs...

    I'm sorry, but I don't understand how that is apparent.

    Might it be apparent, with all the bad publicity that Areva's industry has had over the past six months, that they'd be happy to report any the data indicating no-contamination?

    A subsidiary of EdF (French utility) operates the plant. They have apparently reported that there was no release of radioactive material. If that is the case, then they should be measuring normal amounts of [mostly background] radioactivity around and outside the plant.

    I think this is relevant.

    I don't understand, if there's nothing significant, why WOULDN'T they report it.

    Seriously?

    "And now the news!

    Today, in France, nothing significant happened. Film at eleven!"

    Sorry, that just hit me funny! :rofl:

    It's not a nuclear plant (as in a commercial nuclear power plant or fuel fabrication facility), but the facility does process or recycle waste from medical, research and perhaps operating nuclear plants. There is a MOX fuel fabrication facility, AREVA's MELOX plant, nearby.
