Japan Commissions Inspection on Reactor, Wall Street Journal, April 23, 2011:
The Japanese government’s nuclear safety agency said Saturday it has commissioned an investigation into the ability of the No. 1 reactor at the stricken Fukushima Daiichi to withstand further earthquakes in the wake of the March 11 disasters, amid concern that pouring water crucial to cool fuel rods into the reactor could conceivably weaken its structure. [...]
Japanese state broadcaster NHK reported early Saturday that the Japanese government has expressed concern about the structural strength of the Fukushima Daiichi plant’s No. 1 reactor, saying water injections to cool fuel rods since the 9.0 earthquake and tsunami March 11 may be making the vessel less earthquake-resistant. [...]
But some experts have pointed out that since reactors weren’t designed to be filled up with water, the process could put strain on structures and possibly cause cracks, especially if the area were hit by another major tremor as aftershocks continue to rumble around Japan. [...]

Reactor 1 water level concerns, NHK, April 23, 2011:
The Japanese government has expressed concern about the structural strength of the Fukushima Dai-ichi nuclear power plant’s Number 1 reactor. It says the ongoing water injections may be making the vessel less earthquake resistant. [...]
TEPCO wants the water level to reach the top of the fuel rods in
reactors one and three by mid July, so it can cool them under more
stable conditions. [...]TEPCO says the water accumulation will not compromise the structure. But the Nuclear and Industrial Safety Agency says large amounts of water can make the building less earthquake-proof.
The agency says it needs to check whether the suppression pool pipes can withstand higher levels of pressure from the extra water.

It’s a simple calculation, Measure the height, and calculate
The pressure at the bottom.
Design pressure is 60 psi, the containment handled 120 psi before the venting.
So add 120 feet of water and you hit the pressure limits, the real problem is a quake will stress the containment.
With the luck the Japanese have it will happen the day after its filled
Report Comment
Some of these reports don’t make any sense. Reactor 1 is already flooded over 5 meters – so too late. The core is in melt. By radiation spikes recently – not contained. Which containment are they referring to? Secondary, primary vessel, floor? It’s past primary and by levels of radiation beyond direct human intervention. The anemic data and disinformation reports are in disarray. I believe some time ago they’re standing back and just letting them emit. Turning on a pump or spigot, arranging a press conference or robot photo op, controlling press information on status, readings and effects – what else can they do except mitigate liability at this point? There’s no official or independently verified list of human “workers” to date. It’s bollocks. A slurry of “working on it” theories and ideas come out after independent disclosures or leaked levels and scathing reports are released. That’s usually followed by unscientific agency safety assurances. Why are we pretending there’s any effective containment, or clinging to fake, unverified rolling disclosures? That doesn’t make sense – unless you’re GE and the news of primary vessel failure is unwelcomed for business and your other reactors are implicated worldwide. I’m not GE, or TEPCo or any other operator or distributor with profit concerns in this game. My motives, expense and risks are personal in opposition to theirs. Theirs are sociopathic. Mine are human safety. We disagree. I want the verifiable data.

Drinks lot of water is good as it is been also been proved scientifically and by the experts too !!

the reactors were not designed to … [fill in blank].
we’ll give you a little bow and say we are sorry as we continue the looting of earth and the great unwashed.

Further than what is clearly not there, if the vessels are in tact after all these weeks – they can just provide one current photo of them as such. The drawn illustrations are ridiculous. If they or a robot can’t get close enough to photograph them in tact or existing on site, then we assume the reactors are not in tact and TEPCo et al can stop the “worker” subterfuge reports and nonsense theater. A US submarine camera took a photo of TMI rods. The Phoenix program assays weren’t released. These controlled, partial public reports are silly, misleading and entirely bogus. I advocate public release of data from assets we’ve funded. Stat.
