no, a pellet has 1.1cm diameter.

@lillymunster this is for #3 : www.oecd-nea.org , but #1 is smaller

13 m³ + control rods etc. ; maybe ~20m³ (cubic meters)

Approx dimensions for the single sump in the elevation
sump 2ft x 3.33 ft x 16.63 feet
sump metric 609.6mm x 1014.98mm x 5068.82mm

volume of pit

sump 2ft x 3.33 ft x 16.63 feet
sump metric 609.6mm x 1014.98mm x 5068.82mm


.60966 x 1.01398 x 5.06882 =
3.122 cu meters

If there are two pits we could assume equal and double the calculation. We could try to alternatively do a "round" moat type pit calculation and see if it changes anything.

@Edano so if 1 pit, only 3.122 cu meters of space/volume, if two that is only 6.2 cu meters of volume. So on the smaller volume end only half could fall into the pit if 2 pits. If it is a round pit and the smaller end that might get caught up. If more on the larger end it would exceed the round pit I would guess.

@Edano how much does gasses and vapors impact volume? Or do they? Most of the cesium went up in smoke or steam? Does hydrogen production impact volume or is it just a byproduct of the reaction that doesn't impact volume in a notable way?

@Edano did you see from last night JMA denies that they reported an increase in leukemia? They clarified that they didn't report it and said they don't know right now if there is an increase.

Repeating from last night. This is the program TEPCO says they used for their calculations:
The utility used the Modular Accident Analysis Program developed by Fauske & Associates LLC, a subsidiary of U.S.-based Westinghouse Electric and a pioneer in computer models that analyze severe accidents at nuclear power plants.

@estacion TEPCO likely could not calculate it in a much more detailed way. Even with a program they can't get an exact volume because they just do not know.

@estacion right. What is the motivation behind TEPCO's statements, that is frequently more important than the statement.

The analysis done by the Institute of Applied Energy commissioned by the national government, 85% of fuel dropped to the Containment Vessel in Reactor 1, and 70% of fuel dropped to the Containment Vessels in Reactors 2 and 3. The researchers at the Institute pointed out the possibility of the damage to the stainless-steel shroud that surrounds the fuel core, and of the corium having eaten away the concrete floor of the Containment Vessel up to 2 meters deep. Because of that, they also said it was possible that the RPV got tilted. ex-skf.blogspot.com

@Pedro Jesus right now nobody knows. Yes, increased patient concern causing more to go to a doctor could increase diagnosis. The telling detail would be the type of leukemia, if they are the acute quick onset type vs,. the typical long latency types. We have public health data through June but it will take a full year to have enough data to really show a trend or not. Even with that you still might get a jump due to more patients going to doctors out of worry. I would be more interested in finding year to year totals of the acute onset leukemias only but right now we don't have access to that level of detail. If we could find such it might show an increase or not.

This says incident in the turbine side:
www.elpais.com

The steam exhaust registered Cofrentes NPP (Valencia) has been produced by the rupture of the drain line control valve of the turbine, as reported by the office in a statement.

These drainage lines, whose diameter is 2.5 inches, are being subjected to the surveillance program of erosion corrosion, under which was scheduled to replace the now broken leg during the next refueling outage. As a first step after the incident, the owner proceeded to power down to disengage the drive, isolate the main steam lines, allowing safe access for workers and so they may identify the source of the leak.

The event, which has not alleged risk to humans or the environment has been classified as Level 0 on the International Nuclear Event Scale.

The EU leader, Marga Sanz, called for the closure of the plant and said keep it open "is foolhardy." Commitment Rep. Juan Ponce demanded his retirement.

The fukushima ostriches are mostly still alive. Some were set free to forage for food and people have been leaving them food where they know them to be. Others going to the farm to feed them. www.facebook.com

TEPCO released new employee rad exposure data:
We have sequentially submitted interim reports to Ministry of Health,
Labor and Welfare on the following items when each reporting due date
comes, and have made announcements.
(a) Evaluation results of internal exposure dose from March to September
(16,916 persons. Remaining 173 persons including 16 persons whose
contact information was unknown will be evaluated hereafter.)*1
(b) From (a), detailed evaluation*2 results of internal exposure dose for
workers with the aggregate evaluation of internal and external
exposure dose over 250mSv (6 persons)
(c) From (a), evaluation results of internal exposure dose for workers
with evaluation of internal exposure dose over 20mSv (351 persons,
including 6 persons in (b))

@lillymunster as to tepco's motivation for their latest "confession" and noda's newest remark about cold shutdown from today i repeat my earlier post:

tepco and govj had a problem: with unknown status of corium, they could have never been able to announce a "cold shutdown", which is a prerequirement for lifting the evacuation zones. so they made an agreement and decided to invent a fantastic story about corium having eroded a tiny little bit into the concrete containment, but not over the steel barrier, and now it is stable. so by admitting a little bit damage to conctrete without fully breaking the containment they think they can cover up the entire truth and people will swallow it. problem solved. this is what i make of that story. they bought a bunch of "experts" and added some ridiculous details like "65cm" to make it sound realistic. how can they determine the depth without seeing it ?

it is a lie, they probably know that the corium is already outside. compare tepco's statements with their previous, i linked to it yesterday. in may they admitted a meltdown, but entirely denied a vessel breach, although we all knew it better. it won't be different today. it is all about politics and pr, and probably the iaea sits on their back.
