Fuel Rod Removal Operation Begins At Tsunami-hit Fukushima

rtoz writes "TEPCO (Tokyo Electric Power Company) has started removing fuel rods from a storage pond at the Unit 4 reactor building of Tsunami-hit Fukushima Daiichi Nuclear power station in Japan. The first of the fuel-rod assemblies at the plant's No. 4 reactor building was transferred from an underwater rack on the fifth floor to a portable cask. This step is an early milestone in decommissioning the facility amid doubts about whether the rods had been damaged and posed a radiation risk. 22 unused fuels will be moved to the cask a task which is planned to be completed by November 19. After being filled with fuel, the cask will be closed with a lid, and following decontamination, will be taken down to ground level and transported to the common spent fuel pool on a trailer. It is planned to take approximately one week from placing the fuel into the cask at the spent fuel pool to storing it in the common pool. The entire removal of all fuel inside the Unit 4 spent fuel pool is planned to take until the end of 2014."

    Good. It's about time to get those fuel rods out of there.

    The US needs Yucca Mountain. It's not perfect, but it's a lot better to have fuel rods inside a mountain than at reactor sites. After all, Yucca Mountain is in an area so isolated that it used to be used for above-ground testing of nuclear weapons.

      I'm still waiting for an announcement about some scientist "discovering" that subduction zones are a good place to bury stuff that you don't want to worry about seeing back up any time soon.

    They keep saying "first we'll do this and then we'll do that" with the spent fuel.
    But the one question no one seems able to answer is what you ultimately will do with all that toxic spent fuel. Simply speaking there is no answer, no plan for what to do with nuclear waste from any plant damaged or otherwise.

      No-one takes in another country's nuclear waste, at least not spent fuel or reprocessed waste. Britain and France used to reprocess spent fuel from Japan but the recovered uranium and plutonium was reformatted into fresh fuel elements and they along with the waste from the reprocessing operation has been returned to Japan.

    They are just starting to move fuel assemblies which where removed from their reactors prior to the earthquake. Where it will be a good thing to get these things out of the leaky cooling pools the real work has still not started. It's not really going to be possible to start working on the reactors which melted down for a few more years. Even then, it won't be possible for humans to approach so the work will require invention of remotely operated tools that can deal with the unique situation, and tasks necessary to clean up this mess.

    It took 14 years to decommission Three Mile Island after the accident there which was exceedingly less complicated because the containment structures where not blown open and there was only one reactor involved. We are decades away from being done here with multiple reactors at least partially melted down, sea water being used for coolant and the extensive damage to the containment structures.

    This is a great start, but until they get all of the high level material into an inherently stable condition and/or offsite we won't be able to breath easy. Keep it going TEPCO."

    I didn't see the expected statement that these idiots will parade the hot rods through downtown Tokyo to reassure everybody they have the situation well under control.

    Reagan reversed the ban Carter imposed on commercial reprocessing of spent fuel in the US in the early 80s. Nobody has funded a reprocessing operation (other than the lines used to produce weapons-grade materials from military breeder reactors) in the US for various reasons; raw uranium is cheap, nobody wants to use MOX fuel for cost and operating licence reasons and the US government is in charge of making spent fuel go away for which the generating companies pay a levy, currently over $30 billion dollars over the past few decades (it's what paid for Yucca Mountain).

    disallowed in the United States for purely political reasons.

    From that which you linked:

    In March 1999, the U.S. Department of Energy (DOE) reversed its policy and signed a contract with a consortium of Duke Energy, COGEMA, and Stone & Webster (DCS) to design and operate a mixed oxide (MOX) fuel fabrication facility. Site preparation at the Savannah River Site (South Carolina) began in October 2005.[11] In 2011 the New York Times reported "...11 years after the government awarded a construction contract, the cost of the project has soared to nearly $5 billion. The vast concrete and steel structure is a half-finished hulk, and the government has yet to find a single customer, despite offers of lucrative subsidies." TVA (currently the most likely customer) said in April 2011 that it would delay a decision until it could see how MOX fuel performed in the nuclear accident at Fukushima Daiichi.[12]

    Sounds like no-one's interested because it's prohibitively expensive even with big subsidies from the Gov't.
