Title: TEPCO investigates Fukushima plant fuel pool
Source: NHK
Date: Thursday, February 09, 2012 17:57 +0900 (JST)

[...] Reactor Number 4 [...] was off line at the time of the accident on March 11th and no active fuel was inside the reactor. [...]

Recall this unconfirmed report posted recently on Fukushima Diary: Report: 'Empty' Reactor No. 4 was actually filled with nuclear fuel

[...] Tepco was planning to start reactor 4 in the AM of 311. (The nuclear fuel was in reactor) [...]

    ..sooo..the reactor wasn’t all fired up…just loaded…does it matter..?..it’s all mixed together now..isn’t it?
    ..hey Tepco..let’s just be about.. together…and spend some idle time watching for activity in/of the Subduction zone…near which ..in your brilliance …YOU built nuclear reactors.

    So in was NON-active fuel??? Can someone explain the difference? So how did they then have a “partial meltdown” of NON-active fuel..get out the dictionary guys..we need a PHD in semantics here…

      The fuel hadn’t been activated yet, after the quake water levels dropped thus exposing the rods. Rods do not need to be activated in ordered to have a reaction. They just need to be exposed. This is the reason all rods are transferred to the reactor via water pool. Unless rod are in dry cask they are at risk of a reaction in they are not submerged in water. I think LOL. I’m not a nuclear scientist, that just makes sense to me from what I’ve ascertained.

        Actually I AM WRONG, the reason there was a meltdown was because the water level in storage pool in #4 dropped exposing the used rods. These rods could be up to 30yrs old. From what I gather it takes many years for the rods to become “inactive” to a point they can be dry casked and removed from the reactor house. I could be wrong on this as well…..if that’s the case sorry for further confusion.

      Hmmm. Euphemisms…
      Resting fuel vs working fuel.
      Scholar fuel vs Athlete fuel.
      Hello Kitty fuel vs Godzilla fuel.
      Gentle Daughter fuel, Wise Grandfather fuel.
      (Wish I spoke Japanese.)
      Rice fuel vs Fugu fuel.

      Spring fuel asleep

      I believe that new fuel rods have not undergone fission yet (no fission products/decay heat). Used or active fuel rods would be rods that have been involved in the fission process (hot) because of fission products and decay heat. The used rods have to be kept in water to remove the heat generated from the decay of fission products. Water in the Spent fuel pools is there to provide mainly cooling of the rods (decay heat) and to lower the radiation from the rods.

    More “Whose on first” communications strategy.

    What an utter shell game.

    Near the anniversary of this freaking disaster and this is news? Why? Is the question I ask.

    Such information should have been clear and concise from day one.

    Why and how did it blow?

    Where was the fuel?

    Grade 5 questions, never answered, only obfuscated.

    Completely corrupt and criminal.

    My understanding is that they were in the process of loading up the core thus it was only partially full if there was any fuel in it at all but I’m pretty sure there was as I got this from another source, not Fuku Diary. Anyway, at this juncture what’s another meltdown going to matter i that nightmarish facility. I’m sorry, I should not feel that way, just a tad pessimistic. Gee, I don’t know why??

    I’m sorry but if this is what the world can expect from Japans brightest we are F&*&*^%CKED! Hey I have an idea Japan, how about STOP spewing your radioactive crap all over our country? Well? Can yah stop it please? Russia had theirs stopped in 8 months and it was FAR WORCE than Japan. So YOU SAY!

    Here is the photo from March 27, 2011 which shows that the yellow cap of the RPV is put aside.

    so, it is commonly known that there was no fuel inside the reactor, but it was parked inside the Spent Fuel Pool.
    Value of this information from NHK: zero.

    We can discuss this all day long it’s not going to make a difference one way or the other. The fact is that the Giant Plutonium Jeanie left the bottle nearly a year ago, wish all we want cause there ain’t NO WAY of putting it back in. :(

    I said it before and I’ll say it again. The Japanese are still running around saying “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”, “Oh shit!”,!”,

    Nothing about this report is inconsistent with what they’ve been reporting all along.

    The reactor cap and the containment cap were off at the time of the earthquake because they were “relining” the reactor.

    They’ve been reporting 1535 assemblies in the pool and 0 in the core since day 1.

    The only person I’ve heard dispute this is PattieB. I have no proof one way or the other and to me it makes no difference, however it has been curious as to how some of the damage occurred to the #4 building.

    The thing that ticks me off is they say they are doing this inspection and totally ignore the fact that the #4SFP burned like mad two days ago – spewing more steam and likely more radiation that imaginable.

    I guess “active fuel” does not mean old warheads undergoing plutonium purification. This is the dirty secret that further impedes the flow of information. It’s an issue of national security, after all.

    I feel so secure.

    whats this???? seems that tepco wants to run away and deny they poisoned the WHOLE earth, especially the oceans, with daily tons and tons of deadly radioactivity,, this would anger alot of people here, because there reporting has been inconsistent and full of lies, we know everything and you are to blame, tepco you can run but you cant hide.. this all comes right on the anniversary on the event thats changed the world mind u…

    Everything I read says TEPCO had just completed replacing Unit 4′s stainless steel shroud and the core was void.

    The rubber like inter-tube gate seal that keeps water from passing through SFP to the core via a chute (used for refueling) failed during the earthquake, along with the circulating pump to cool #4′s SFP (lost power?). So, the SFP slowly begins losing water as it leaks back into the core besides the water sloshing over the sides during the great quake and aftershocks.

    1331 assemblies weighing around 700pounds each or over 465tons where the SFP was designed for only half that weight amount since shroud replacement was unheard of when these units were built.

    It’s amazing the SFP is still in place when literally crammed full of fuel assemblies.

    TEPCO’s first thing on their ‘to do’ list was to place reinforcing underneath Unit 4′s SFP, they did that. How well they did it, we don’t know yet. Why it will take two years to get around to unloading Unit 4′s SFP is a crime.
