А откуда у вас 7-8-9 л/час? Разговор шел про 2-3 м3/час с блока.
Ну такая подача сейчас в третий
(...). Когда обсуждали ранее - народ на форуме делил на выпаривание/утечку. Тогда на выпаривание давали 2-3.
У меня этого нет, я взял всю подачу 9л. Цифры для "порядков", скорее иллюстрация, чем расчёты.
Вот выйдет счас пресс екретарь ТЭПКО и скажет: "У нас с паром выходит 6 литров в час."
Это будет значить что у него там куча народу бегала и ГО заглянула и термометров понатыкали. И то я скорее всего ему не поверю в конкретной цифре. в 6(+-)3 поверить смогу чуть полегче.
С конденсатом ещё сложне. Какя часть осела , на каких конструкция, сколько стекло именнов БВ.
Это гадание на кофейной гуще, которое может привести к двум противоположным ответам. Может.
В качестве варианта мы его рассмотрели и прикинули. Игры ума, если позволите.
Первым пунктом программы всё равно идёт попадание мусора - потом намыв с дождём, потом только конденсат.
Интерес тут чисто умозрительный, на истину никто не претендует.

Продолжение откровений пресс секретаря (во влип парняга) ТЭПКи:
From TEPCO's Presser on May 12 (Part 2): "We Don't Know Whether the Fuel Rods Have Melted Or Crumbled"
Understatements galore from TEPCO's Matsumoto on May 12.
About the shape of the fuel rods in the RPV:
"It is true that the reactor core is not in the normal position inside the RPV. But the temperature of the RPV is low enough [93.7 degrees Celsius at the bottom of the RPV, as of May 11] . So we believe that the fuel rod clusters now sit lower than the normal position, or at the bottom. We do not know the amount, or the shape of the fuel rod clusters that currently exist below the normal position."
"We do not know for sure whether the entire fuel rods have collapsed or only part of them collapsed. Still, it is possible that that a thin crust may have formed, and the inside is like a molten lava. Therefore, the RPV temperature as measured may be low but the inside of the melted/collapsed fuel rods may be hot. We admit to that possibility and don't deny that possibility. However, as the part that is under water gets cooler, sooner or later the inside gets cooled and solidify."
About the risk of hydrogen explosion:
"From the time we started the nitrogen gas injection, we didn't consider hydrogen explosion as imminent risk. Right now, the RPV is cooled, and there is very little risk of hydrogen generation from zirconium [cladding]. The continued nitrogen gas injection is also effective [in preventing hydrogen explosion].
Whether the fuels are being cooled:
"The current condition as we see is that the fuel rods have melted and gone down lower [than the normal position] or they have crumbled, but in the process they are being cooled by water or by the steam if part of the rods are still exposed."
Whether the thermometer for the RPV is accurate:
"We believe they (there are multiple thermometers) are accurate."
A: Whether it is a "meltdown"?:
R.:"We don't believe it is so-called "China Syndrome", where the melted fuels go through the bottom of the RPV, through the bottom of Containment Vessel and the reactor building's foundation. We think the fuel rods, even though they don't retain the original shape any more, remain inside the RPV and are being cooled."
About the structural integrity of the RPV:
"We can still measure the temperature at the bottom of the RPV. Even though there seems to be a damage that cause some water to leak, the bottom is still there. Also, if the [melted/collapsed] fuel rods had already dropped to the Containment Vessel, the pressure and the temperature inside the Containment Vessel should be much higher."
Possibility that the RPV temperature is low because the melted/collapsed fuel rods have dropped through the bottom of the RPV:
"We cannot deny that possibility."

TEPCO: A Few Centimeter Diameter Hole at the Bottom of Reactor 1's Pressure Vessel, maybeThe bottom of the Reactor Pressure Vessel (RPV) is 16 centimeters thick, as per TEPCO's press conference on May 12 morning.
In the evening press conference, TEPCO said their calculation showed there must be a hole a few centimeter in diameter at the bottom of the RPV that is leaking water.
According to TEPCO, 8 tons/hour water is being poured into the RPV to cool the fuel. The cumulative amount of water that's been poured exceeds 10,000 cubic meters (tons). On finding the water level inside the RPV was at most 4 meters from the bottom of the RPV. TEPCO calculated the damage to the RPV from the amount of water that's leaked from the RPV, and came up with a possibility of a hole a few centimeters in diameter.
