  • Utility eyes LNG for Hamaoka decision
    Kyodo
    Monday, May 9, 2011

    NAGOYA — Chubu Electric Power Co. was planning to hold another extraordinary board meeting Monday to determine the fate of its controversial Hamaoka nuclear power plant in Shizuoka Prefecture as its chairman flew to the Middle East to shop for LNG.

    The power plant, which was built close to a known fault line, was urged to close Friday by Prime Minister Naoto Kan, who is concerned another catastrophic quake — the widely feared "big one" — could produce another nuclear disaster south of Tokyo.

    After an inconclusive board meeting Saturday, Toshio Mita, chairman of the utility, which serves the central Chubu region around Nagoya, departed for Qatar to procure supplies of liquefied natural gas to run its thermal power plants, officials said.

    In the meantime, other officials continued brainstorming ways to keep power supply stable this summer if the utility decides to grant the request, they said. The prime minister's request is not legally binding.

    On Sunday, Kan urged the company to cooperate and emphasized that he had no intention of pursuing the suspension of any other nuclear power plant aside from Hamaoka.

    At issue is whether Chubu Electric can secure enough generation capacity for the summer by rebooting its suspended thermal power plants, and whether it can procure enough fuel to do it at a time when Tokyo Electric Power Co., the nation's biggest utility, is trying to do the very same thing to deal with the nuclear crisis at its Fukushima No. 1 power plant.

    Mita will meet with Qatari Energy and Industry Minister Mohammed Saleh Al-Sada and the president of the state-run LNG company Qatargas about the utility's needs, officials said.

    The utility is also examining if it can be held responsible by shareholders if its earnings suffer after accepting the government's request, which is not enforceable under current law, the officials said. While refusing the highly publicized request appears difficult, some within the company have objections, they said.

    Deputy Chief Cabinet Secretary Yoshito Sengoku separately defended Kan's request by emphasizing the high likelihood of the Hamaoka plant being hit by the powerful quake, which is expected to strike within 30 years, and questioning its preparedness for an earthquake or tsunami. "The likelihood of a quake measuring intensity 6 (on the Japanese seismic scale of 7), or bigger, in the area of the Hamaoka plant within 30 years is higher than 80 percent. Other nuclear plants are less than 10 percent likely, with most less than 1 percent," Sengoku said.

  • The gal is defined as 1 centimeter per second squared (1 cm/s²).

  • @estacion Oh I bet that meeting in Quatar is going to be unpleasant. The brokers or whomever their chairman is going to try to buy LNG from. They know Chubu is in a difficult position, I am sure the price on LNG just went way up. :-(

  • @all "New policy guidelines. In August 2003, the JAEC announced new guidelines for plutonium management. Under the new arrangement, utilities are expected to submit annually a plan covering their use of plutonium to be separated in the following year. The plan is supposed to include the following information:
    • Planned amount of reprocessing and of recovered plutonium during the year;
    • Estimated amount of plutonium in inventory at the end of previous year;
    • Planned sites of the nuclear reactors that will recycle the recovered plutonium;
    • Estimated amount of plutonium use during the year; and • Estimated timing and duration of plutonium use.
    The following information can be added later:
    • Planned amount of MOX fabrication and number of fuel assemblies during the
    year; and
    • Planned timing of MOX loading and the name of the power plant." (Planned usage of MOX doesn't have to be included in annual report, but can be amended at any time. Pleads the question, does the GoJ or their Nuclear Regulatory Commission really know the status of Plutonium at Fukushima I?)

  • @marie rich thanks! Those are some big movements when your talking about a building basement.
    by Nancy 5/9/2011 2:34:56 AM

  • How can you have 'estimated' and 'inventory' in the same sentence? Isn't that an oxymoron?

    by marie rich 5/9/2011 2:35:52 AM

  • @Nancy I believe I read (somewhere?) that the movement in one of the basements was beyond design basis, but don't remember the details. Sorry...
    by marie rich 5/9/2011 2:37:44 AM

  • @smoss we can't find a concrete answer on how much MOX is at Fukushima if TEPCO's PR statements are any indication the GoJ doesn't know how much MOX was there either.
    by Nancy 5/9/2011 2:37:55 AM

  • @marie rich yes, I heard that a couple of places.

  • @smoss hmm. but they loaded mox last summer. Something isn't matching up. Were they able to regain approval later on or did they find a way around the local refusal?
    by Nancy 5/9/2011 3:19:02 AM

  • @all Following a timeline: 8 Feb. 2001: TEPCO announces freeze on power plant construction (including thermal power plants in Fukushima Pref.)
    26 Feb. 2001: Governor states that “loading of MOX fuel is not possible at the moment”
    29 March 2001: TEPCO abandons May implementation
    29 Aug. 2002: TEPCO fabrication of inspection data revealed
    24 Sep. 2002: Governor retracts 'prior consent'
    20 January 2010: application process recommenced with request for prior consent
    6 August 2010 prior consent granted (see above) Areva/Melox
    Contract signed for 32 assemblies *****No date for fuel shipment given***** Fuel loaded 8/21/2010 Reactor started with MOX 9/18/2010

  • @all Forgot the link www.cnic.jp 1
    by smoss 5/9/2011 3:20:46 AM

  • @smoss so the big question is what did they do to get that consent put back in place? IIRC there was a governor that ended up in jail on trumped up charges. Did a new governor give the approval? What would it be about running mox that was worth ruining someone's career and the extensive PR campaign they did with the locals? There had to have been some major motivator to go through all of this vs. just running uranium.
    by Nancy 5/9/2011 3:23:31 AM

  • @Nancy There was that big fight over it, I thought in September of last year. TEPCO narrowly won approval?
    by radioguy 5/9/2011 3:24:26 AM

  • @all MOX fuel has been stored at Fukushima I -3 since January 2000. www.cnic.jp 1
    by smoss 5/9/2011 3:24:46 AM

  • @smoss from what people found it sounded like a 1999 shipment and another one more recently of more MOX. What is the motivation? Why do all this over a fuel?
    by Nancy 5/9/2011 3:25:48 AM

  • @Nancy I think the motivator was that they were running low on capacity, and had all these old, underpowered reactors, and they could amp them up a little and maybe eke another 5-10 years out of them.
    by radioguy 5/9/2011 3:26:22 AM

  • @Nancy 14 Sep. 1999: Takahama-3 MOX fuel data falsification revealed
    30 Sep. 1999: JCO criticality accident
    16 Dec. 1999: Takahama-4 MOX fuel data falsification revealed
    These two incidents definately had an impact.
    by smoss 5/9/2011 3:26:50 AM

  • Besides, they need them to generate the power required to keep it all cool and circulating.
    by radioguy 5/9/2011 3:27:46 AM

  • @Nancy @radioguy If you pull up that link (the spam one) from the NPFM, in their opinion it is a Plutonium issue, and MOX is one way the Japanese are choosing to deal with it.
    by smoss 5/9/2011 3:30:17 AM

  • @radioguy IIRC does MOX have higher output of power? I know it is harder on the reactors, they had to have them approved. Trying to figure out if the additional power results in a profit. I suppose over time vs. running on uranium or shutting down.
    by Nancy 5/9/2011 3:30:34 AM

  • @smoss do they get incentives for running MOX since it uses plutonium
    by Nancy 5/9/2011 3:31:22 AM

  • I think it is used mostly because it is cheaper, it is reprocessed fuel. It behaves a bit differently then the usual fuel though.
    by Ralph Unger 5/9/2011 3:31:46 AM

  • @Nancy There was the BNFL shipment that had the falsified quality assurances, which was sent back from en route, and replaced by the shipment from Le Hague, also 1999, right? Then we saw the Tokai Fuel Works accident in 1999, where they were milling 4.6% entiched uranium from Areva in Washington, for the MOX reactor I think, then the 2007 accident, and I think a 2010 radioactivity release into groundwater.
    by radioguy 5/9/2011 3:31:59 AM

  • "Goto said that the MOX also has a lower melting point than the other reactor fuels. The Fukushima facility began using MOX fuel in September 2010, becoming the third plant in Japan to do so, according to MOX supplier AREVA." dcbureau.org
    by Ralph Unger 5/9/2011 3:32:43 AM

  • They weren't all MOX related, but there seems to be a sort of parallel history.

  • @Nancy @radioguy NPFM "Japan's Spent Fuel and Plutonium Management Challenges"
    by smoss 5/9/2011 3:33:09 AM

  • " One reason proponents of MOX reactor fuel support its use is because, once the fuel is burned in a reactor, it is so hot that terrorists would not be able to steal a fuel assembly."
    by Ralph Unger 5/9/2011 3:36:31 AM

  • @Nancy It ups th epower output. I don't remember the numbers, but I remember thinking . o O (Wouldn't they love to MOX up R1 to up that 400Mw to closer to the BWR-4's.)
    by radioguy 5/9/2011 3:37:21 AM

  • @Ralph Unger Lovely. We'll use this because it makes the waste even HARDER to deal with.
    by radioguy 5/9/2011 3:38:18 AM

  • @Nancy - thanks! and Holyshit
    by inCalifornia 5/9/2011 3:38:38 AM

  • @radioguy the idea of taking these old "ford pinto" reactors and running basically a racing fuel in them, this is concerning. TEPCO seemed to think it was a good idea, I am assuming there was money to be made.
    by Nancy 5/9/2011 3:38:52 AM

  • But now we are safe from terrorists, they never put their lives at risk!.
