Title: Fukushima No. 2 plant was ‘near meltdown’
Source: The Yomiuri Shimbun
Date: Feb. 10, 2012

The Fukushima No. 2 nuclear power plant was “near meltdown”  [...] according to the head of the plant. [...] 

Plant chief Naohiro Masuda, in charge of plant operations since the crisis, told reporters Wednesday, “The No. 2 plant almost suffered the same fate as No. 1.”

[...] a Nuclear Emergency Situation Declaration was issued for both the No. 1 and No. 2 plants. The declaration was lifted for the No. 2 plant in December.

The Problem Then

[...] The tsunami caused the No. 2 plant’s seawater pumps, used to cool reactors, to fail. Of the plant’s four reactors, three were in danger of meltdown. 

Luckily, one external high-voltage power line still functioned, allowing plant staff in the central control room to monitor data on internal reactor temperatures and water levels.

By March 15, the No. 2 plant’s four reactors reached a state of cold shutdown without any leakage of radioactive materials. [...]

The Problem Now

The Fukushima prefectural government conducted an on-site inspection at the No. 2 plant on Wednesday and repeated a request to TEPCO to decommission the facility. 

Masuda did not elaborate and said, “At the moment, I can only say we’ll maintain a state of cold shutdown.”

Read the report here

It’s not entirely clear what the statement “By March 15, the No. 2 plant’s four reactors reached a state of cold shutdown without any leakage of radioactive materials” means.

A) Was there no leakage at any time?
or
B) Was there not leakage after the plant reached a ‘state of cold shutdown’ on March 15?

Also, why use the phrase “state of cold shutdown” instead of “cold shutdown”? “State” is also included when referring to the “state of cold shutdown” at Fukushima Daiichi. As three full meltdowns/melt-throughs occurred at Daiichi, using the same terminology to describe Daini is troubling.

    Cold shutdown on March 15th. Pardon my lack of knowledge, but is it possible to attain a cold shutdown in 3&1/2 to 4 days?

    I remember the news report 11 months ago stating the tsunami had swamped the turbine room, breaking cooling pipes and that TONS of saltwater flooded INTO the reactor pressure vessel.

    I am wondering why they are even mentioning Daini right now.

    Do they know something we don’t? – Maybe that ‘all is not well’ at Daini? And in anticipation of this news leaking out they are putting out ‘not to worry’ PR blab?

    BTW I am sure others have made this comment, but TEPCO stepping down from handling the Fukushima nightmare, well isn’t that pretty much letting government step in and pick up the tab?

    ‘Government’ meaning of course the taxpayers?

    “We’ve poisoned ya real bad, folks, sorry about that, and boy o boy, is it ever gonna cost ya!

    melt down? how about melt out? does that count,, im lost here, ive been following since march, but how many times we heard melt down and helt thru, melt out etc,, some of them have already had there fuel leave the building,, somehow they have contained the temperature on reactor 2 even though its likely past the containment,,, they just continue to spin the lies and new stories,, are the japanese so gullable to listen as they constantly change,, from one low of melt-thru to another high of cold shutdown,, i just wonder how hot those coriums are and a safe bet would be they left the building but how did they manage to reach and cool them? heh

    When they say ‘State’ of cold shutdown, a partial meltdown comes to mind, otherwise it would just be shutdown, right ?

    If the fuel is altered in any way, it can’t be shutdown normally, so they say ‘state of cold shutdown’ ….

    something must have happened …

    I sense some clarification is in order here.

    My career is electrical engineering.
    My present focus is remote temperature sensing.

    The fundamental problem with the idea of sensing temperature in any of the reactors, especially locations within an RPV is that with a melt through, the energy output from the corium is no longer IN the RPV. Never mind that there is basically no water left in the RPV!! So the temperature sensors are measuring places within the RPV when there is likely little to no heat source within the RPV.
    Which explains why the RPVs can be said to be “stable”.

    The TEPCO folks are using some really devious verbal tricks to create the impression that things are in some stable state.

    Sort of like looking at your house thermostat temp readout when the house is on fire. The house could be seriously engulfed in flames and the interior thermostat would never know it.
    At least not in any sort of “timely” manner.

    I have been following this Fuku problem since day one and the technical responses from TEPCO and the Japanese govt have been (from a technical perspective) nothing short of the nuclear version of

    “…what the meaning of the word ‘is’ is.”

    Look…we’ve got an acknowledgement from every plane except the 4 you shot down!!

    He says their arir defense now only claims 3 aircraft confirmed.

    The fourth may only be damaged.

    Its good that TEPCO has advised us of the cold shut down…..
    At least this is proof that Daini has been in a stable cold shut down state since March 11 2011?
    I would like to add one more thing about this so called “cold shut down” condition at Daini…….
    BULL SH#T YOU LYING BASTARDS!
    P.S. can anyone here show me some recent areal photos of Diani?
    Peace.

    “State” of cold shutdown implies a temporary condition.
    “Cold shutdown” means it’s over and permanently cold.

    Maybe TEPCO and the Japanese Government will get together and change the name of Fukushima Prefecture to “Cold Shutdown”, which would mean that, technically, all the reactors at both Fukushima Daiichi and Fukushima Daiini would be in “Cold Shutdown”.

    Does anyone remember when Japan created a city and named it Usa? Things made there and shipped to America were labled “MADE IN USA”.

    “At the moment, I can only say we’ll maintain a state of cold shutdown.”

    Let hope after 30 years there are still Japanese people exist to maintain a state of cold shutdown.

    – This is typical of the ‘modern’ approach that insists that problems of physics are subject to public relations.

    This is not factual, since the complex suffered at least ONE massive explosion!

    How can you have cold shut down without a “reactor”?

    There are only three piles of radioactiv­e junk in Fukushima and those are no longer reactors!
    Example:
    If a tank blows up you have a burned out hulk or mass of scrap but you don;t have a tank any more; that ceased to exist when it blew up…

    RE: Cold Shutdown:
    It is a misuse of the term to describe a reactor after meltdown as ‘in cold shutdown’. As the fuel assembly is destroyed no shutdown is possible. Fuel is melted together and impossible to control directly. Even if pressure and temperatur­­e are unalarming momentaril­­y ‘cold shutdown’ implies complete control which is impossible after meltdown.

    Why can’t the Nuclear Industry accept that a melted down reactor is not a normal condition for a reactor which is shut down for any number of reasons and is ABLE TO BE STARTED UP AGAIN SAFELY!
    This is a perfect example of Nuclear Oriented Bad Science (N☢ BS) being used to provide dis-inform­ation to the public and only serves to call into question those in the Industry that should be speaking out against this Nuclear Baloney (NB)!

    Japan gov’t to finally admit indefinite forced depopulation of large zones around Fukushima plant.

    That says it all… doesn't it? Not forced evacuations! Forced depopulations!

    One of the main things I'm begining to see… confusing 'Criticality' with something blowing up! Criticality is NOT an explosive thing, unless it's happening with Urainum 235, or Plutonium 239! Those to will chain-up in a fast enough way to give you a 'blast' and U-235 can't even do so without help! Reactor rods are mostly U-238, a different element. Criticality ONLY causes geat levels of heat and radioactive out-pourings!

    SO!… it's the P-239 rods in #4's pool… and possibly what's sitting in reactors #5 & #6 that can possibly constitute a 'BOMB' waiting to go off!

    The others… much like reactor #1 did… could separate the water into hydrogen and oxygen… then with a spark, blow-out. The coriums in the ground… add methane to this mixture.

    #3's pool… had 10+ years old Plutonium-239 rods in it, and is why it's destruction was mini-nuke-like. But, its rods had much Plutonium-240 in with it… that element makes a blast fizzle-out mostly.

    Consider the factors folks… #2 is not even high on the dangers board at this point in time. Slow the water influx back down… mind the #1 & #2 pools… and get back to the real problems.
