  • @Pedro thanks. I would hate to have such a good source of info being overlooked because it could have a virus. Like I said, I have not encountered the problem but too many others have for me to just let it go without passing the info on.

  • Radiation levels to be checked at 100 places in Tokyo
    Thursday 09th June, 04:20 AM JST

    TOKYO —
    The Tokyo metropolitan government announced Wednesday it will gauge radiation levels in the air at 100 locations in the metropolis, in response to requests from cities, towns and villages for more expanded coverage than the current measurement conducted at the metropolitan government building in Shinjuku Ward.

    The metropolis is planning to have staff travel for one week from June 15 to measure radiation and publish the results on its website. It will also rent 70 dosimeters to local governments from June 20. www.japantoday.com

  • @all Question to pose: Is there a required amount of time that MOX fuel assemblies must be/sit in the SFP prior to insertion in the reactor core?
    by smoss 6/9/2011 2:56:02 AM

  • @Lurking If there were any known virus on that page I would have gotten a red flag straight away. Front page is clean, although I haven't checked all the links in it. I even checked the "China women for dating" link at it's clean. Let me know if you have problems. My Security Suite is one of the best and is updated several times a day. If there's a name for a virus it will detect it. Sometimes it even gives false detections although that has only happened to me a couple of times. And thank you for the input. =)
    by Pedro Jesus 6/9/2011 2:57:15 AM

  • @Pedro thanks for the input. I did not get any warnings either but I also run pretty good protection.
    by Lurking 6/9/2011 2:58:30 AM

  • @smoss Never heard of that. There is an amount of time it must sit in the SFP prior to being locked in dry casks but not before it can be inserted in the reactor, afaik.
    by Pedro Jesus 6/9/2011 3:02:00 AM

  • @Pedro Jesus un-irradiated MOX fuel assemblies must be stored in the SFP prior to insertion...I just am curious to know if there are guidelines to time...especially on the short end, ie. minimum
    by smoss 6/9/2011 3:04:50 AM

  • @all I am finding discrepancies in the amount of MOX fuel assemblies delivered to Ikata-3:
    by smoss 6/9/2011 3:12:27 AM

  • @smoss From what I read they store it there for safety. IIRC they put even uranium fuel in the SFP for a short time before loading. It does something to irradiate it or prep it. Dean or RBeaner might know the technical details.

  • @smoss do you have sources?
    by lillymunster 6/9/2011 3:12:58 AM

  • My records show 21 assemblies in 2009 to Ikata.

    by Mart 6/9/2011 3:14:03 AM

  • @smoss Ask Dean when he's here. He knows about the standard procedure. I don't have any information about the necessity of storing MOX fuel assemblies in the SFP before installing them in the reactor but there might be some security issues regarding the transport. They might have to be stabilized although I've never come across any information regarding that. I'll keep an eye on that.
    by Pedro Jesus 6/9/2011 3:18:46 AM

  • @all (Hit return too soon) The MOX fuel being shipped this time is for Kyushu Electric's Genkai-3 reactor (PWR, 1,180 MW) in Saga Prefecture (16 assemblies), Shikoku Electric's Ikata-3 reactor (PWR, 890 MW) in Ehime Prefecture (21 assemblies), and Chubu Electric's Hamaoka-4 reactor (BWR, 1,137 MW) in Shizuoka Prefecture Prefecture (28 assemblies). The assemblies are transported in casks, which weigh around 100 metric tons each, including the fuel assemblies. They will be off-loaded directly at the ports alongside the Genkai and Ikata plants and at the Omaezaki port, about 3 kilometers from the Hamaoka plant. ***this source duplicates your number @lillymunster lost the link momentarily*** The MOX fuel that is used at this phase of the program is manufactured by Areva at its MELOX plant. The fuel that is being loaded in reactors was delivered from France in a shipment that reached Japan in May 2009. It contained 24 assemblies for Ikata-3, 28 for Hamaoka-4, and 16 for Genkai-3. In addition, 60 MOX fuel assemblies were delivered for use in Tokyo Electric's Fukishima I-3 and Kashiwazaki-Kariwa-3 BWR units earlier, in 1999 and 2001, respectively. This fuel, manufactured by Belgonucleaire, is awaiting approval by local authorities. Another MELOX-manufactured fuel shipment is scheduled to leave France shortly, probably this March. ***This second bit is from the fissile materials blog, which has in the past been rejected as spam. This cite stated that there were 24 assemblies for Ikata-3, not 21.***

  • @smoss @lillymunster I don't know if this helps...it's an NRC doc and has some info on MOX and plant prep etc..pg.10 has info on MOX storage in SFPs. pbadupws.nrc.gov
    by LM 6/9/2011 3:20:50 AM

  • These have some info about storing MOX in a SFP before use. Mox stored in sfp had 15% decay to americum in 4 years.

    by lillymunster 6/9/2011 3:25:31 AM

  • @smoss Mind that I'm talking about reprocessed MOX fuel shipped to NPPs that is ready to be used as nuclear fuel. I'm not acquainted with the reprocessing procedures, but I do know they are not done at NPPs that do not possess a specific reprocessing facility (if there are any). AREVA reprocesses nuclear fuel so maybe we can find some info regarding that you're asking.

  • @Pedro Jesus the fuel cycle is ship LEU spent fuel to France or UK for reprocessing. They send back MOX assemblies and encased rad waste. The rad waste goes to their new long term storage facility in Japan, the MOX rods to the designated reactor.

    by smoss 6/9/2011 3:28:47 AM

  • My forum has had all kinds of fun names for the different things they have tried. Operation Super Glue has always been my favorite. It is also the only one still being used. Operation Calgon Take Me Away is what we called the bath salt tracers when they were trying to find the water leaks. It's nice to add some levity to the dismal facts that keep being presented.

    by smoss 6/9/2011 3:30:42 AM

  • This is the one I found. Has a number of things I have not found elsewhere about concerns about various MOX deliveries not mentioned by Greenpeace, CNIC etc. I will see what I can cross reference off of that. Either they have really good info others don't or they are overstating things. Surprised CNIC didn't have this info. Worth tracking down because if true there are lots more problems www.fissilematerials.org
    by lillymunster 6/9/2011 3:36:25 AM

  • @all Before I distracted myself with the differing #'s for MOX fuel assemblies delivered to Ikata-3, I was actually trying to determine a general timeline between delivery of assemblies and insertion of assemblies. Because every 18 months 1/3 of the MOX fuel has to be renewed...was kind of wondering if new shipments to Fukushima I-3 would have to have been pre-arranged, or pre-exsistant. @lilymunster That's the link!
    by smoss 6/9/2011 3:39:04 AM

  • @smoss not sure why it let me post it and not you.. I wasn't aware of the 18 month timeline for refueling. If you happen upon the source for that can you make sure Elaine or I get a copy? If this is true for refueling and some of these reactors were loaded before, I think at least one was running MOX prior to the FUKU 2010 install. That other one would be needing refueling. /
    I should have the current database of deliveries done and online tomorrow. We can use that to check and sort this new info you found.
    by lillymunster 6/9/2011 3:43:30 AM

  • There was an April and IIRC a May 2011 incoming MOX shipments that were stopped after the EQ and meltdowns.
    by lillymunster 6/9/2011 3:44:25 AM

  • I am wondering if the two different colors of polymer are a different mix. I will see what I can dig up.
    by Lurking 6/9/2011 3:46:50 AM

  • @lillymunster Guidelines for MOX refueling actually come from AREVA...Nathalie Bonnefoy, from the MELOX Division of AREVA La Hague, France, said, "In this site, all the MOX fuel has been already loaded in the reactor (it started in October 2010)," no MOX fuel is stored on site here. On others sites, a part of the MOX fuel is stored on site (every 18 months you have to renew one third of the MOX fuel because it has lost efficiency). dcbureau.org
    by smoss 6/9/2011 3:49:15 AM

  • @lillymunster Yes, French energy company AREVA provides MOX fuel for NPPs around the world. They are the world leaders in the nuclear industry. They are aiming to enter the world top 3 in renewable energy until 2012 as well. We're talking about the big industry here. AREVA covers a huge stake of the world's energy sector focusing their operative power in 5 different fronts: uranium mining; nuclear fuel conversion, enrichment and design; nuclear reactors design and construction and NPPs maintenance; recycling, transport and cleaning of nuclear fuel and NPPs dismantling services; and last but not least development of wind energy, bioenergy, solar power and hydrogen power solutions. TEPCO is nothing compared to this monster. Check them out and you might find where that MOX fuel went to.

    Now about the MOX fuel being used at Fukushima Daiichi #3, it only attained criticality around October 2010. There was no reactor at Fukushima using MOX fuel prior to that.
    by Pedro Jesus 6/9/2011 3:49:41 AM

  • We're going to hear lots of AREVA in the near future since they are most likely to be the ones decommissioning all 6 reactors at Fukushima Daiichi and cleaning up the mess when the situation comes under control (one way or the other), working alongside Toshiba.
