@xxx you posted a blueprint of a reactor deck the other day. Do you know where it came from and what reactor power plant it came from?
by Nancy 4/18/2011 12:47:48 PM

This was from physicsforum but i dont know from which reactor
by xxx 4/18/2011 12:48:52 PM

Could someone please pin this link? It is the govt. of Georgia's Japanese embassy. They post reactor and radiation testing data in English. translate.google.com Done.

@Majjham Zazen's link is very good. Just ask yourself one question. What happens if the so-called recovery does a 180? Do you think the financial system is healthy enough to deal with a double dip?
by Hank Scorpio 4/18/2011 12:49:01 PM

@xxx Thanks. Trying to figure out if it was specifically one of the units at Fukushima. I should have some new location overlays for 4 and 3 tomorrow. I found some more pre-quake images of the insides of 3 and 4 that gave more usable data.

hi all, just a few words from work...
the 5 meters water flooded in #4 reactor building is likely to be a good new, in my opinion.
If the building is roughly 40 meters long, 5 meters in the basement is 8000 m3. Given the fact it's not empty, I may consider there's something like 4000 m3 of water there. As there is about 150 m3 spread everyday on the SFP, if I remember well, that means that most of the spreaded water is finally leaking in the building basement.
The good thing is that this radioactive water is not leaking to the sea or to the soil for now.
The bad thing is that Tepco workers or robots can't enter the building; but given the reactor is empty, there are no need to enter the building in order to secure the area, in my opinion.
by Jocelyn Mayer 4/18/2011 12:53:15 PM

Downside is that 4 has a boatload of rods in its SFP. I expect they need to be removed, and/or an effective longer term cooling method must be derived -- that water is likely pretty contaminated, correct?
by Markfm 4/18/2011 12:55:36 PM

@Hank Scorpio I think that the financial system health is as rotten as is Fukushima HEALTH......

Good GMT+8 evening to all. And, of course, Tepco is still in firefighting mode.
It's situations like below that keeps me on needles when I try to visualize what could unfold when a typhoon hits or even just skirts by ground zero in its present state of disarray and disrepair.

Trying to locate a short circuit or a fitting torn loose or tracing the valve that got knocked by typhoon-churned debris -- right in the midst of a howling typhoon, or a weld that peeled off after getting slammed by flying sheetmetal. I can't help but also worry that many components of the facility are 40 years old already.

From @NHK post, citing Tepco:
> At 2:34 pm, April 17th, the occurrence of a short circuit caused by the lack of repair of
> the end of the unused cable which is connected parallel to the power of spent fuel common
> pool caused the circuit breaker of the power side to open resulting in suspended power
> supply to the spent fuelcommon pool.

Robots detect dangerous spike in reactor 3 radiation search.japantimes.co.jp 57 mSv/hr max in 3, 49 mSv/hr max in 1. "On Saturday, workers detected 270 millisieverts per hour at the south side of the same floor of the No. 1 unit before the robot went inside the north side of the same building, Tepco said."

Success no given in Tepco road map search.japantimes.co.jp "The plan includes a new tactic — filling the containment vessels of reactors 1, 2 and 3 with enough water to cover the pressure vessels, which contain the fuel rods. ... By effectively filling 80 or 90 percent of the containment vessels, each of which can hold from 6,000 to 7,400 tons of water, the weight will make them more vulnerable to aftershocks, he said."
by Markfm 4/18/2011 1:15:09 PM

I wonder if the plan to fill the buildings with water came before or after they figured out that 4 already had 5 m of water in it?
by Markfm 4/18/2011 1:16:32 PM

@Markfm : they are leaking. how do they think they can fill them ?

Hmm, containment buildings that are already leaking -- check! Create vast new amounts of highly radioactive water -- check! Buildings not really built as swimming pools, continuing aftershocks -- check! Sounds like a plan.

@Jocelyn Mayer I seem to recall early in the disaster that the #4 SFP was dry, or very close to it. That means the rods were exposed and started to break down which eventually led to the explosion in the Reactor #4 building. By the time they were able to add water to the pool, the damage had already been done, and continues to be done. If the explosion damaged the #4 SFP, then there is at least one leak in the walls and/or floor of that pool. They have been constantly adding water to the pool, so I'm making an educated guess that they do indeed have multiple and substantial leaks. Additionally, the heat of the fuel rods is boiling off substantial amounts of the water being added to the pool. Therefore, any water flowing out of that pool is carrying radioactive particles and will continue to do so until they can somehow get the fuel out of the pool and safely secured. As far as cracks/leaks in the entire facility allowing water to leak into the ground or ocean, think about this for a second: the facility has been subjected to more than 1000 quakes since the 9.0 monster, 13 of which have been 6.5 in magnitude or stronger, including 3 at 7.0 or above. Based on the above information, logic dictates that the Fukushima nuclear facility is completely riddled with cracks and leaking like a sieve.

Anyone see any radiation reports for #2 building interior? Robots were supposed to check there Monday.

good morning all
by dean 4/18/2011 1:37:33 PM

The fact of having a 6.6 earth quake in the SW of the Ring of Fire is what worries me....
by Majjham Zazen 4/18/2011 1:37:56 PM

@James Ward: yes, the fuel in #4 has been uncovered, at least twice in my opinion, there was an explosion due to hydrogen coming from damaged fuel / water, there fire due to the heat. Leaking water is radioactive that's why I think it's much better that Tepco find this water in the building basement than to have it widely leaking to the sea.
by Jocelyn Mayer 4/18/2011 1:39:56 PM

hi Dean !
by Jocelyn Mayer 4/18/2011 1:40:07 PM

@Markfm: reactor buildings are likely to be designed being mostly tight as they are the secondary containment around the reactor...
They might not be absolutely tight, but they have to be mostly: they are supposed to be slightly depressurized in normal conditions in order to avoid radioactive leaks.
by Jocelyn Mayer 4/18/2011 1:44:49 PM

@Markfm Anyone have a source for the "5 meters of water in reactor 4 building". Plan is calling for filling containment vessel, not the buildings at 1-3. search.japantimes.co.jp

@Markfm Tickers are about as accurate as headlines. They probably were refering to the SFP#4 level, probably above the rods. My guess. But if the source is twitter....

The source was the main new flash ticker at the NHK news site.
by Markfm 4/18/2011 1:49:45 PM

Look at the pressure readings for unit 2 and 3 and tell me that c/v is pressurized. Look at the pictures of the bldgs. and tell me about 'normal'. Half of Tepcos mistakes were made when assuming 'normal' and 'what should happen'. There is still no knowledge of why unit 2's torus breached.

Marie -- I'll be interested if they got robot readings inside #2, just to see what they come up with; also curious about what #1 RPV will really take pressure-wise. LM -- thanks, I knew I had read it earlier.
by Markfm 4/18/2011 1:56:44 PM

hey, they have been flooding the buildings for a month now. and one thing is for sure: there is not a single structure left that can hold any water. that's why they have highly contaminated water in the cellars and in the other buildings and in the ocean. there is no chance to "flood" anything.
