@Edano: I think 5 meters is the inside diameter of the RPV. Might be wrong...by Jocelyn Mayer 4/18/2011 5:05:26 PM
www.freeimagehosting.net i know people hate my work on this, but this is about the size.

by xxx via Img21.imageshack.us 4/18/2011 5:08:19 PM- @Edano: as I remember, this layout is 41.6 m large. I think the building matches BWR-3, ie #1 reactor, then building size (but not drywell / RPV) has to be scaled up to match BWR-4, ie #2, #3, #4 & #5 reactors, isn't it ?by Jocelyn Mayer 4/18/2011 5:08:34 PM
This is #1 and it is not the same as the other units but as they are all different...
by elainekirk 4/18/2011 5:09:05 PM- @xxx: yes, this is the reactor...by Jocelyn Mayer 4/18/2011 5:09:15 PM
- @elainekirk: according to G.E. data, BWR-3 & BWR-4 are mostly the same design. The only documented difference is the core density, ie the layout inside the reactor. No other design change.by Jocelyn Mayer 4/18/2011 5:10:15 PM
- @Jo I have another one for ~3 or ~4 which shows how the square basement is followed by tiers of differing dimensions I passed it to @Nnacy but will look for the copy in my filesby elainekirk 4/18/2011 5:12:21 PM
- @xxx : good point.by Edano 4/18/2011 5:13:12 PM
The measurements and placement on those are off. The well is not that large.by Nancy 4/18/2011 5:15:21 PM
Containment cap is about 10 metres or about 30 feet across
Reactor vessel cap 5050mm = 5.05 metres - about 16.5 feet across
Well = 12.5 meters - 37.5 feet across
Building long = 41500mm = 41.5 metres - 124.50 feet

The good thing is that it's easy to locate the containment vessel: it is located at the exact center of the square basement, which is logical as the torus is round and just fits into the building.by Jocelyn Mayer 4/18/2011 5:16:17 PM
- @Jocelyn Mayer those specs don't include the surrounding building and work floor. From what I have been told those are somewhat flexibleby Nancy 4/18/2011 5:16:45 PM
- @Nancy: is 41.6 meters the size of #1 or the size of #2, #3 & #4 ?by Jocelyn Mayer 4/18/2011 5:16:46 PM
- Rough long on all. They seem to be the same length with the width differingby Nancy 4/18/2011 5:17:48 PM
- @Nancy: you're right. But the main components always remain at the same place in the basement building. The upper part is truncated on the sea side.by Jocelyn Mayer 4/18/2011 5:18:12 PM

by Nancy via Houseoffoust 4/18/2011 5:18:25 PM- The well is offset of the centerline but closer to the middle than the outer walls. The crane landmark overlays I am working on line up with that also.by Nancy 4/18/2011 5:19:13 PM
- @Nancy: all basement buildings are square. It's a design constraint: they have to in order to house the torus...by Jocelyn Mayer 4/18/2011 5:19:14 PM
- @Jocelyn Mayer i know that but the newer units are wider. The wells are not huge like half the building in those drawings and are not right against the outer wallsby Nancy 4/18/2011 5:20:09 PM
- If you will zoom my image with big red arrow you will see open coreby xxx 4/18/2011 5:21:31 PM
- uploading some pics brbby Nancy 4/18/2011 5:21:33 PM
- @Nancy: yes, #2, #3, #4 & #5 are wider (still square, though, #6 is BWR-5, completely different design); It seems to me the dimensions are 41.6m x 41.6m for #1, about 48m x 48m for #2, #3, #4;
or is 41.6 for #2, #3, #4 ?by Jocelyn Mayer 4/18/2011 5:23:12 PM 
by Nancy via Houseoffoust 4/18/2011 5:24:13 PM- @Jocelyn Mayer : you are 100% correct.by Edano 4/18/2011 5:24:18 PM
by Nancy via Houseoffoust 4/18/2011 5:24:36 PM
by Nancy via Houseoffoust 4/18/2011 5:24:48 PM- Those are rough, not done working on them yetby Nancy 4/18/2011 5:25:09 PM
- @Jocelyn Mayer i had a post that got held up in mods earlier, missed nancy... but the 1997 procedure for the "shroud replacement" gives very detailed procedures on the "decontaimentain" of reactor durinng "maintanice" I am sure its imporved since then but quite informative... i believe it states that the steam dryer section was stored in "spent pool etc" .. nklistener had posted the reports last week....by fitter 4/18/2011 5:25:43 PM
- @Jocelyn Mayer One is not squareby Nancy 4/18/2011 5:25:58 PM
- @fitter if you have the link that might help locate some of the offloaded structures in 4by Nancy 4/18/2011 5:26:42 PM
- @Nancy: great drawings ! You've got it !
#1 basement is square, just checked to be sure...by Jocelyn Mayer 4/18/2011 5:28:10 PM - @Jocelyn Mayer @Nancy i am having issues due to power/internt and partial damage to a job site from tornadoes... i am realay behind... sorry if i am repating ... i'll try and find it in my favorites... but if you see nkl he probably has it a his finger tips...by fitter 4/18/2011 5:29:16 PM
- @Jocelyn Mayer yes but go look at the overhead shots of the plant 1's above ground building is much narrower than the others that are nearly squareby Nancy 4/18/2011 5:29:29 PM
- @fitter I can get it from NHK he usually shows up later in the dayby Nancy 4/18/2011 5:29:53 PM
- @fitter I have a bunch of piping close up shots from under the work floor on 3 when you get time.by Nancy 4/18/2011 5:30:26 PM
- @Nancy i agree, everyone confuses undergriound and roof lines..... on the buildby fitter 4/18/2011 5:30:33 PM
- @Nancy thank ask nkl for the welding procedure report also they are at the same time... in our buisness when we say the drawings are gone with the wind "we" mean it...by fitter 4/18/2011 5:31:57 PM
- i don't know everyday the same discussion. the base of the buildings is a square. the roof is not. but still the containment is centered (to the base). of cousrse it is centered, because it is round, the torus stretching nearly to the walls.by Edano 4/18/2011 5:32:23 PM
- @Nancy: have to go from work; will gladly go on sharing later.by Jocelyn Mayer 4/18/2011 5:34:03 PM
- @Edano there are some minor differences where the well then appears on the work floor based on the layout and width of the upper building around it. Like the fact that 1 is narrower.by Nancy 4/18/2011 5:34:49 PM
- @Nancy : but nancy we have a no 1 blueprint.by Edano 4/18/2011 5:35:50 PM
- @Edano That elevation you posted is reactor 1by Nancy 4/18/2011 5:36:06 PM
- yes, and it is square.by Edano 4/18/2011 5:36:30 PM
- @Nancy: I measured, more than once, #1 basement is exactly square. The blueprint says it's 41.558 m x 41.56 m large; OK, there's a 2 millimeters difference...by Jocelyn Mayer 4/18/2011 5:38:19 PM
