@Peter Melzer There were multiple waves of Tsunami, and they don't drop back like a normal "wave". They build on each other and just keep coming.by RBeaner 5/19/2011 7:54:18 PM

@Peter Melzer www.yomiuri.co.jpby Edano 5/19/2011 7:56:37 PM- @Edano I assume you have a personnal opinion on multiple wave, besides yomiuriby RBeaner 5/19/2011 8:04:46 PM
- @all.. I am posing a question, the exhaust pipes going to the stacks are above ground as we see them.. I wonder if other connections are made from within the building..by Dean 5/19/2011 8:06:40 PM

@Edano- power lines of different voltages can be on the same grid with the use of transformers. The Island of Japan uses both 50Hz and 60Hz power and cannot be mixed, which is what I think that diagram represents.by Lethbridgean 5/19/2011 8:16:12 PM
@Edano , thanks for the link. However, the first pic. in this series supposedly taken at 15:42 : www.tepco.co.jp shows the water just arriving.
by Peter Melzer via Tepco.co.jp 5/19/2011 8:20:12 PM- @all- if you look at the bottom of the VENT stack it looks to me that the vertical vent tower is made up from individual pipes. Therefore the flow from one cannot possibly flow back into the other...Funny this arguement has gone on so long....by Lethbridgean 5/19/2011 8:26:16 PM
- leth also.. where are the scrubbers etc located as the exhaust would have to go through those units.. they must be inside?by Dean 5/19/2011 8:27:36 PM

www.foxnews.comby Panserbjorne9 5/19/2011 8:33:36 PM - @Lethbridgean Are you saying, for ex #3 and # vent paths were separated, by anything more than a crappy damper?by RBeaner 5/19/2011 8:34:30 PM
- @ Leth, the ones at the plant which was not a BWR are located in the basement and then the discharge piping goes underground to the stack... all over head ducting piping on the outside of the building is usually not from reactor proper..by Dean 5/19/2011 8:35:46 PM
- back to writing.. be back in a bitby Dean 5/19/2011 8:37:33 PM
- @RBeaner - look at where they tie into the vent stack and you'll see that the vertical vent stack is made up from individual large diameter pipes. And a damper is an incorrect use of the word if what you mean is a check valve.by Lethbridgean 5/19/2011 8:37:53 PM
- @Dean I'm not looking at rpv vents, but comon work area vents.by RBeaner 5/19/2011 8:38:48 PM
TOKYO: Japan's largest power utility has begun shutting down its third nuclear reactor five days after discovering an increase in iodine in the reactor's water. It said no radiation had leaked. It was the third such incident at Tokyo Electric Power Co Inc's Fukushima nuclear plant 250km north-east of Tokyo since an earthquake last Friday.

msowww.anu.edu.auby elainekirk 5/19/2011 8:39:16 PM- RBeaner I wonder if we have some sort of prints or some reports that show common ducting, electrical or piping ducts... have you seen anything ?by Dean 5/19/2011 8:40:27 PM
Look at nancy photo posted 1:40 earlier (14:37 est). You see the big pipe from 3 and the big pipe from 4 tire together into an even bigger pipe, at the bottom of the tower. It is a common vent stack.by Markfm 5/19/2011 8:40:45 PM- Photo is very clear.by Markfm 5/19/2011 8:41:20 PM
- @Lethbridgean I haven't seen the particulr design, and i'm not vouching for it... The issue is did it bleed from #3 to #4 through damaged exhaust ducting??by RBeaner 5/19/2011 8:42:26 PM
- @RBeaner - if they went into individual piping that makes up the vertical vent stack then it would be impossible unless the top of the vent stack was closed off to the atmosphere, by your afforementioned damper.... en.wikipedia.org(architecture)#Automated_zone_dampers Here is the closes use of the word "damper" when it comes to gas flow...In a chimney it is more commonly refered to as a "flue". A check valve serves a different purpose and the word damper is not used even though the mechanism might be similar mechanically.by Lethbridgean 5/19/2011 8:45:20 PM
- 14:57 est, that is.by Markfm 5/19/2011 8:45:40 PM
- @Lethbridgean OK , damper is a bad term, I have no desire to cling to it. whatever, the term, valves in the exhaust system failed to perform as advertised.by RBeaner 5/19/2011 8:49:22 PM
- @RBeaner - I thought we had a vid or picture that shows they were working fine before the boom and before the tsunami. It all goes back to why is this so important? Because without this unplausable senario we can and should assume that the hydrogen that blow up in R4 came from the SFP and no place else, and Tepco is lying.......AGAIN.......by Lethbridgean 5/19/2011 8:57:11 PM
- On the plus side it is a meti doc re bwr venting

on the downside you need to translateby elainekirk 5/19/2011 9:05:43 PM - @Lethbridgean I, at this point, don'y believe that ANY SFP has contibuted any explosive power, on any given day.by RBeaner 5/19/2011 9:07:48 PM
- this one is probably a lot better but still in japanese
www.meti.go.jpby elainekirk 5/19/2011 9:12:09 PM - @Markfm I agree!! They tie together.by RBeaner 5/19/2011 9:13:51 PM
- If you are saying the hydrogen from #3 went to #4 to cause the explosion there, not good assumption. It would have blown up long before it got through all those pipes !!by wtm 5/19/2011 9:14:48 PM
- @RBeaner - sorry to hear that but I am not surprised by your continued denial. Especially given the fact that the heat load on SFP #4 was so great and if the refueling gate seals lost air to keep the seal then the water level and meters of water above the rods would not have taken long to boil off/evaporate.by Lethbridgean 5/19/2011 9:15:25 PM
- And the pipse would have also blown up as they would have still had hydrogen in them.by wtm 5/19/2011 9:15:33 PM
- @wtm there was a escape passage between 3&4 on one of the upper levels it is pretty certainby elainekirk 5/19/2011 9:18:21 PM
- @Dean In emergency, the BWR's bypass the filtration/monitoring system.by RBeaner 5/19/2011 9:29:10 PM
- well, again, though it has been said before: the tower in the photos is the south tower. it has four separate stacks. but this is not the tower between 1/2 and 3/4. these towers have only 1 common stack, the pipes from 1/2 and 3/4 are unified before the towers. so, regarding these two towers, a steam bypass is possible, though in my opinion very unlikely.by Edano 5/19/2011 9:29:35 PM
