Narrator: Hydrogen gas has been building up in the upper part of the unit 3 building. [...]

Tepco Main Office, Speaker 1: We could ask the national self-defence army to blow the panel up from the seaside using a firearm.

Tepco Main Office, Speaker 2
: No. We’ve thought about that but there are many important things underneath.

Tepco Main Office, Speaker 1: But it will blow up anyway.

Narrator: After all, they couldn’t come to an agreement.

    They bow the reactor and the radioactive pollution would "attack" the rest of the planet via the jet stream and especially North America!.

    wouldn't it be better to open a hole to let the hydrogen gas escape..????? Why not give it a try???? Venting???

    Notice Unit 2 had/has a blowout panel missing so the building vents and didn't blowup. Units 1,3,4,5, & 6 had their blowout panels welded shut. Units 5 & 6 had power for cooling via a shared generator and never melted down but TEPCO chopped holes in those roofs just to be sure gases couldn't be trapped inside the buildings.

    TEPCO order the blowout panels of all these type of reactors on the island to be welded shut so as not to cause alarm or be unsightly if strong winds caused them to open up. Unit 2 hadn't undergone the modification yet.

    I read that they welded the blowout panels shut because they had vented the radioactive gas in an earlier earthquake on another nuclear power plant and there was complaints about the radiation released.

      It was the Kashiwazaki–Kariwa Nuclear Power Plant
      “…It was approximately 15 miles from the epicenter of the second strongest earthquake to ever occur at a nuclear plant, the Mw 6.6 July 2007 Chūetsu offshore earthquake. This shook the plant beyond design basis and initiated an extended shutdown for inspection, which indicated that greater earthquake-proofing was needed before operation could be resumed….”

      If your nuclear power plant site doesn't have a blackout, you would vent through the tall towers that are made for filtering and venting.

      Venting inside the secondary containment (which is the building itself) is a last resort effort to keep from venting to outside air.

      Leaks or leaking into the buildings are a different matter, the building is supposed to be able to filter and clean small radioactive leaks. Large leaks or venting, the panels better pop open or you get Units 1,3 & 4 results.

      I also read that the buildings have negative air pressure on some floors so any leaks are contained within the building.

      Then there were the upgrades for emergency venting if those tall stacks somehow malfunctioned, they were supposed to install piping through the building's outside wall to vent directly from primary containment to outside air through a short run of vent pipe. Not sure if some or any of the buildings were upgraded or planed to be upgrades.

      US plants were upgraded with these extra added vents after one of many flaws were found in the original design, like the primary containment is to small to contain a meltdown.

      So I guess, if you have a meltdown, you hope any melted fuel stays within the reactor or primary containment where it can cool then you can remove it later. Even if you have to send fallout around the world through emergency vents, at least you should end up with intact containment holding melted fuel so you know where it is. Wonderful…

    What caught my attention was the statement "No. We’ve thought about that but there are many important things underneath." Just what is underneath #3?

      I was wandering the same thing. My theory is that there is military stuff underneath reactor 3 and that`s why the Japan`s army is staying far from the complex officially a.k.a to avoid any suspicions.

      Remember how Israel developed his own atomic program underneath a civil reactor.

    I think they just wanted to keep the building in one piece where there is a lot of important stuff in them. The plants might of had a plan for meltdowns but I guess it never occurred to them that the spent fuel pools might run dry.

    Whatever option that they may decide to use (firearm, drill, laser)to pierce the vessel, couldn't it be done in a flood of nitrogen to cancel or minimize the possibility of ignition?
    And, what is the thickness?

    It is my understanding that there is no such thing as a blowout panel on any of the Mark I reactor buildings. The panel that blew off #2 was a result of the explosion at #1. So they (or we) got lucky.

      Blowout panels are mentioned in this .pdf for design parameters @ 6.2.3.1 item (10) (never meant for hydrogen release but for relieving the effects of an occasional passing tornado with its pressure causing differentials besides other types of pressure changes) along with all the other described preventive measures that failed Fukushima.

        Yeah I know, the above .pdf is for a ABWR. Here is the .pdf for a BWR (Brown's Ferry plant which is about the same as the reactors 1-4 designs at Fukushima) referring to blowout panels at page 12 and elsewhere with drawings.

        http://www.osti.gov/bridge/servlets/purl/5835351-nR29Hq/5835351.pdf

        "… All blowout panels are modeled as pressure dependent flow areas . The panels are assumed to begin leaking with an area equivalent to 10% of the total panel area, at a pressure differential equivalent to 90% of the design basis pressure differential for the blowout panel. Eighty percent of the total panel area is assumed to be open at the design pressure differential, and all of the blowout panel is assumed to be open at 110% of the design actuation pressure . This modeling approach reflects the results of laboratory tests which indicate that the blowout panel retaining bolts may fail at pressure differentials equivalent to plus or minus 10% of the design value …"

        I'm sure you will get the idea of blowout panels.

          Here is a unconfirmed report (because TEPCO won't admit to it) about the blowout panels at Fukushima and elsewhere.

          http://www.infiniteunknown.net/2012/01/02/fukushima-workers-fukushima-reactor-buildings-of-reactors-1-3-4-blew-up-because-blowout-panels-were-welded-shut/

          "…But at Fukushima, they didn’t open except for the one on Reactor 2. Why?

          Because all the other blowout panels in other reactor buildings had been welded shut by the order of the Nuclear and Industrial Safety Agency after the earthquake in Niigata Prefecture in 2007, when the blowout panels of the reactor at Kashiwazaki-Kariwa Nuclear Power Plant opened.

          What’s wrong with the blowout panels opening?

          From a blogpost and the comment to the post in August, I learn that:

          In the Niigata earthquake in 2007, the blowout panels for the Kashiwazaki reactor opened, and that was unacceptable to the government’s nuclear regulatory agency NISA. So NISA ordered TEPCO to alter the blowout panels so that they would not open. After the earthquake of 2007 (Chuetsu earthquake), all the blowout panels at nuclear power plants that TEPCO operated were welded shut…"

    I want to offer a possible way to open the reactor vessel for hydrogen venting with more finesse and control than blowing a hole in it. Have the hollow core bit fabricated at whatever diameter and length it takes to get through the vessel wall. Have two rubber or epdm belt raceways welded close to the top of the bit. This will be attached by the belts with two diametrically opposed EP motors, for stability. Additional bracing may be needed for increased stability as it drills. To the top of the core bit is attached valve and tube that runs to an evacuated large tank. When the bit accomplishes its task the core may fall to the inside of the reactor or the pressure may push it to the top of the inside of the bit. No matter the hydrogen can make it's way around the core piece to be evacuated out the top of the bit past the valve/gauge. The H is sucked into the new container as it was under some vacuum already. Still flood area with nonflammable nitrogen.

      You can wipe a little foam off the rabid dog's chin, but he is still full of poison.

      Venting damaged atomic buildings is like sticking your finger in the barrel of a murderer's automatic shotgun. He still has plenty more shells.

    Safe clean nuclear energy is revealed as the rabid dog it really is. So dangerous to humans you need the military to come blow the roof off the doghouse and let the mad foam escape.

    Anybody within 10,000 miles of a nuclear plant should keep that mad dog metaphor in mind. And when it goes on a biting frenzy, everyone on earth gets infected.

    The Resident Evil mad nuclear scientists bring Raccoon City to everyone's hometown. Thanks for the electricity too cheap to meter. The nucleocrats will someday get the total world scorn they deserve. There will be no forgiveness from mother nature.

    Artificial radiation alters our human DNA and creates fatal cancers. We have been human guinea pigs of the nuclear scientists and a relatively small number of humans set in motion hundreds of extinction machines. Mostly in the northern hemisphere, but the fallout travels to every place on earth.

    They may control the brain dead population, but unless they build bubble dome cities they still have to breathe the same toxic air. They will die just like the rest of us.

    An EPDM seal that would snug up to the outside of the core bit may be affixed to the top of the reactor vessel in order to keep hydrogen from escaping out from the that potential pathway. Keep it on the inside of the core bit, that becomes a pipe that directs the gas to the attached pipe/tube & tank.

    yes, protect the heavily damaged reactor building from a small caliber artillery shell.

    Geez.

    The building was wrecked and they are worried about some more damage?

    Idiots.
