I just re-read your post above. The steam generators had nothing to do with the decay heat removal system (XC system, for emergency cooling). It was a standalone heat exchanger that tapped into the primary loop inside the main coolant cutout valve boundary as I recall. A thermal siphon...
@rcchap
Your comments here (and in the hindsight thread) are right on. And you are right, decay heat removal in a submarine PWR vs a land based BWR are completely different. I used the submarine PWR example only because (a) I was personally familiar with it and (b) it shows that decay heat...
Has anyone seen or know anything regarding the effects of the drastically altered primary plant chemistry? From what I can tell, they are pumping in seawater, it is turning to steam, and the steam is being vented into the wetwell. If so, this leads to a massive buildup of chloride and sodium...
Returning one reactor to service may not be possible in a relevant time frame due to xenon poisoning following a shutdown from power. Commercial cores use 3-5% enriched fuel. Xenon buildup following a shutdown inserts a substantial amount of negative reactivity.
I'm not sure of the timeframe...
I was an operator in the US Navy. Left the nuclear field at discharge many years ago, but have learned some things about civilian reactor design in the past few days that I don't understand.
In an S5W submarine plant, operation of the main system isolation valves, initiation of decay heat...
Re exposure levels: electricpete's conversion is right on, 8217 microsievierts/hr is 822 mrem/hr.
(Disclaimer: what follows is from my Navy career which ended many years ago. I believe it to still be current)
To put that in perspective, the occupational limit in the US nuclear industry is...
Here's the answer, sort of, from Solidworks...

Sub-assembly "5000000071_King_41931000_UpperFormRllMtg" opens fully resolved likely because the top level assembly was saved in an inconsistent state. There is some data in this sub-assembly (e.g. an annotation view, a mate) that...
Solidworks (thru my VAR) requested copies of the files, am ftp'ing them now. So someone is working on it.
Will post answer(s) when/if they become known.
Colin, we haven't seen the Hole Wizerd issue.
We implemented SW 2007 on our own without support and did pretty well for three years that...
@Dan: I put the top assembly into a new assembly, saved and closed. Upon reopen, all are opening as resolved (not just the previously affected ones. In Tools/Options/Performance, "Automatically Load Lightweight" is now unchecked and I didn't do it. Close file. Go back to...
We recently upgraded from SW2007 to SW2010.
The issue is with a rather large assembly (~1000 parts in a hierarchy of 30 or so subassemblies going five levels deep)
The question is components loading resolved instead of lightweight when loading the top assembly. The problem seems to be with one...
We are currently using MP2 extensively (since 1998 or so), and I'll throw out this caution note to the readers.
MP2 is considered to be a "mature" product and is not scheduled for any upgrades or further development, just maintenance releases to fix known issues. This occurred shortly after...
We use dumb item numbers, the ten digit item number is the filename whether it's an assembly or part. Any intelligence associated with a part/item is in an external database.
We use an Access db that is tied to our ERP db. Thru the Access db, we can create an item number, set up the vendor and...
We are new (couple of months) in SW, three engineers using SW2007 Network, no PDM.
After reading what is available, we decided not to use Toolbox except as a parts configuration tool. We use Toolbox to create a part model, but then treat the result as a separate .sldprt drawing to be reused as...
May be a little late to help, but...
I've used Marsh and concur with yzracer's comment about their durability.
Replaced them with Loveshaw Microjet 5x5, which were more reliable and could be rebuilt in-house more readily. Still had problems with nozzles drying out if not properly shut down...
Does anyone have experience they can share in using SW/ToolBox in conjunction with an existing inventory/BOM/purchasing system?
We are moving from 2D to SW 2007 network with ToolBox. Toolbox scares us a little.
We already have an extensive database of purchased parts (fasteners, bearings...
We are users of the MP2 software you mentioned. It runs throughout our entire engineering/maintenance organization, whether someone wants a light bulb changed or a new production line built. We use it for purchasing, inventory, PM, equipment documentation, BOM's, engineering drawing control, and...
