  • New industry minister vows efforts to resume halted nuclear reactors

    TOKYO, Sept. 3, Kyodo

    Newly appointed industry minister Yoshio Hachiro on Friday vowed to back Prime Minister Yoshihiko Noda's policy of resuming halted nuclear power reactors once their safety is thoroughly checked.

    Hachiro's comment at a news conference is in line with Noda's view that restarting nuclear reactors suspended for regular checkups is necessary to ensure a stable power supply for now.

    The new industry minister also shared Noda's stance on nuclear energy policy in the medium to long term, saying it would be ''very difficult'' to build new nuclear power plants in Japan after the Fukushima nuclear crisis.

  • @joniver, this is hype in my opinion. Anytime a power-generating turbine trips, steam is generated and must be released. The steam may contain hydrogen which can be eliminated with recombiners. I don't know whether such system was installed at North Anna. They usually are. The reactors there are PWRs. The hydrogen the operator released must be in the secondary loop that does not flow through the RPV. Effluent radioactivity is monitored. If radioactivity escapes, the operator must notify the NRC. Hence, we would know about it. No Fukushima-style venting occurred at North Anna. The NRC inspection of the plant is underway because, as Dean pointed out earlier, not all piping may be seismically up to par, and the government wishes to check for possible damage.

  • sept 3 Cesium contamination: Saitama and Chiba Prefecture detected from tea Standards Agency Ministry two days, one specimen from the tea produced in the tea produced in Chiba, Saitama and 3 samples, the provisional regulations of the country (500 becquerels per kilogram), announced that radioactive cesium was detected in excess of. At the request of the ministry had conducted a surprise inspection of foods such as eggs and tea for local governments that are commercially available National Institute of Health Sciences. The ministry has ordered an investigation on the flow of goods, such as status of the two counties for the same lot.

    According to the ministry, the 2720 Becquerel equivalent to more than five times the regulatory limit of tea produced in Chiba Prefecture, was purchased in late May, the Institute, the tea produced in Saitama Prefecture, was purchased in early August, regulation up was detected in becquerels of cesium 800-1530 at least three times the value.

  • East Japan to return to full power Power restrictions will be lifted in eastern Japan including Tokyo early September which is two weeks earlier than initially scheduled as demand for electricity eases due to a cooler weather and improved supply and demand, government said.

    The lifting is also timely as some utilities are reported to resume their operations after having been suspended due to heavy rains, increasing the chances of TEPCO to adequately provide supply of electricity.

    The government issued July 1 an order requiring a reduction of power consumption by companies in the Tokyo and Tohoku regions. In the said decree, major firms which may have violated the required cut down would be imposed fines of up to a million yen. The restriction, scheduled up to Sept. 22, came on account of the critical situation of power supply as a result of the nuclear crisis triggered by the disastrous March 11 quake and tsunami.

    The advance lifting of the order also seeks to improve conditions on reconstruction efforts in the disaster-hit areas, the government added.

    While the government has lifted the restrictions on power usage, it continues to call on households and businesses to trim down their electricity consumption by 15 percent until the end of September.

    Even with the lifting of the order, leading automakers would continue implementing power-cutting measures for the meantime, said the Japan Automobile Manufacturers Association. ht.ly

  • Suggesting that nuclear power is not necessary. Japan can provide enough energy. Of course, they still need to seek replacement energy of renewables.

  • @ peter, venting of steam is a normal occurrence as the reactor is taking to cold shutdown
    by dean 9/2/2011 6:46:38 PM

  • when a pwr vents steam on shutdown it is a thuderous sound but not radioactive

  • The Alexander Higgins article, I fact checked it yesterday assuming if anything in it was true I would send out the original source. The original sources he cited said nothing about the steam being radioactive and did not specify if it the steam was out of the reactor or the turbines. So Higgins made that part up or just incorrectly assumed. He is still on my *&^ list for claiming there were food riots in Japan.

  • @Edano great! It was this last one I saw. Amazing cnstruction! I think Arnie Gundersen said it don't reduse radiation to the atmosphere, but on site - that the main purpose is to lead the radiation up, so it may be possible for the workes to work there? Or do you think it also can reduce the radiation in the atmosphere?

  • Outline of the reactor building covering plan of Unit 1 at Fukushima Daiichi Nuclear
    Power Station
    1.The purpose of cover for the reactor building
    A cover for a reactor building is installed for the purpose of preventing
    diffusion of radioactive materials (radioactive materials discharged from the
    reactor, water vapor from spent fuel pool, rubbles and dust with radioactive
    materials, etc) and shutting off rain water into the reactor building. Therefore, we
    are planning to cover the damaged reactor building with highly airtight material.
    The installment of the cover is a temporary emergency measure until a
    midterm measure is initiated. Under a severe working environment, we are
    planning to install the cover as early as possible. www.tepco.co.jp
    by Mona 9/2/2011 7:18:25 PM

  • Is my English correct if I read that this is for preventing radiation inside the reactor? A Norwegian news paper writes that this shall prevent radioactivity into the air - but that is not right, or?
    by Mona 9/2/2011 7:22:19 PM

  • i think it is really hard to forsee how this works. it highly depends on the technology and the engineering. i think the velding of the sheets is critical, and the thermoplastic behaviour as well as the response to earthquakes and extreme weather. it is a prototype, anything can happen, but i guess they will have lots of problems, comparable to the magical zeolithe mashine issues.
    by Edano 9/2/2011 7:24:38 PM

  • @Edano I think they have very loosely based it on the new cover they are putting over Chernobyl. The Chernobyl cover is a big round arch with a steel skin but looks similar to the Fuku tent.
    by lillymunster 9/2/2011 7:27:16 PM

  • @lillymunster the chernobyl cover will be constructed off the site as a whole and then pushed over the reactor on rails. i think it is a completely different approach.
    by Edano 9/2/2011 7:29:14 PM

  • @Edano The prefab framework seems similar. I would be curious to know if someone has a plan to eventually put steel on the TeppyTents.
    by lillymunster 9/2/2011 7:30:24 PM

  • @ Edano, I was trying to slow motion right after it showed the animation to see if there has been any noticeable changes to the structure,,,, @lilly why don't you put your eye on it and see also
    by dean 9/2/2011 7:31:16 PM

  • back in a bit
    by dean 9/2/2011 7:31:19 PM

  • @Edano yes, I guess noone can tell- much has never been done before, trying to come up with good solutions. At least it isn't the end of all problems, like it could sound in the norwegian newspaper.

  • @Mona no, noone should expect too much.
    by Edano 9/2/2011 7:35:52 PM

  • @lillymunster i am sure the framework is not strong enough to carry a steel cover. there is no support for the frame between the edge poles. this will not be able to withstand a higher load.
    by Edano 9/2/2011 7:39:21 PM

  • @lillymunster , if there was a Fuku-style radioactivity release at North Anna, me, my family and hundreds of thousands of others would be in motels somewhere at least 50 miles away from Mineral..

  • @Peter Melzer that is why I fact checked the claim. :-)

  • @Edano Interessting video- to see how they will built the new sakofag in Chernobyl.
    by Mona 9/2/2011 7:40:53 PM

  • the "click" connection of the frame will not hold if the steel bends.
    by Edano 9/2/2011 7:41:19 PM

  • @Mona , if they install fliters for the contaminated air funneled out of the tent, they may catch some radioactivity.

  • @Edano This was a more complicated construction, but then it are supposed to last also. It didn't impress me like the Japanese construction, but it was also many words I did not understand, I think it maybe is time to say goodnight for me. ;) @Peter Melzer That was uplifting, let's hope that will help. Good night folks. Your're all so great, thank you-
    keep up. :)

  • @joniver Sometimes he links to or cites something accurately, sometimes he doesn't. It is a total gamble so I always go look at what source he says he found something at and figure it out for myself. :-)
