BWR Orientation (North)
« on: Oct 02, 2004, 05:21 »
Most people would hesitate before asking a stupid question, but I am ready to step right up. As we say here, there are no stupid questions, but there are plenty of inquisitive idiots!  ;)

 Every place I have seen other than here, it has always been 0 (and 360). Some people tell me Browns Ferry is 180 degrees out of the rest of the world, but others tell me it is all GE / BWR.  ;D

And please, definitely explain "other" if you vote that way!!

25 views and no votes besides mine???

I guess there really are some stupid questions!

(Of course, if no one else can understand why North would EVER be 180 degrees, my conclusion regarding BFN being 180 out from the rest of the world is proven!)

I don't think "North" is ever aligned with the actual Cardinal Direction, either magnetic or geographic.  Pilgrim's "plant north" is almost due east by the compass.  I also don't think this is unique to BWR's.  I think I remember working a two-unit PWR with mirror image containments where "North" was in the middle.

it's been a while, but as recall, 0/360 is where the MS/FW lines enter (or leave) the drywell and isn't supposed to indicate North, people just started calling it that.

Does anyone know why there is such a thing as "plant north"?  I've always wondered, but could never stay focussed long enough to ask :)

"Plant North" is just a way of keeping the orientation of things in perspective.  People in different buildings or elevations can coordinate things as long as they work from the same reference.  As has been posted before, it has nothing to do with actual direction.  Two plants built from the same exact design will have the same "North", but they will probably face different directions.

I work in a 2 unit BWR and will have to get out the maps to check to see in degrees. Both units are oriented the same direction, not mirror images. Now if it was a PWR it would be really easy cause everyone knows that boron grows on the north side of the valve! 8)

Kinda like the SNUPPS that did get built.  Plant North is the same at both but only one actually faces north with its north.

It varies from site to site. Clinton faced Northeast, the prints called it Plant North. Look at most sites from Google Map, and you'll see very few are North / South aligned. Since I came from the Navy, I was used to Forward and Aft, no matter which way it pointed.

By GE Nomenclature the Plant North is as AZ 0 where the Steam Lines penetrate the Drywell.. At Fermi it was East.
