I know most of you have wandered around (or climbed around) inside the biowall, drywell, D-Ring, etc. looking for some damn valve that the house tech told you was in Alpha Loop only to find it in Charlie Loop 40 mrem later.
Okay nukes, what's out there to assist us in finding valves, transmitters, etc? What's the best you've seen and the worst?

The Valve Locator books at St. Lucie and Turkey Point work pretty well. While they are not perfect, they are pretty clsoe. They come from a database that were put together by the ALARA groups with assistance from Maintenance, Ops and others. They save a bunch of time and dose.

Shearon Harris was by far the best I have seen. They had big maps at every ingress point to a major area with valves numbered on each map. Every valve had a tag with large numbers identifying it. You could also go to the HP window and get a map for every area with the valve numbers on it. They also had large maps around the HP window with valve numbers on them. The rest do not compare, they are scum in my opinion compared to the Shearon Harris way.

Usually valve lineups had good locations of the valves. Back that up with the maps at RP, and generally you were in business..

Jerry Hiatt, Chief Technical Officer-Bartlett Nuclear, has produced an exceptionally helpful Light Water Reactor basic training package intended for those new to the commercial nuclear power industry.
I found it so well organized that it serves as my library's sole systems reference book.

We've got a surrogate tour at Callaway that I've found pretty useful for locating components prior to going into containment. You can choose to have components identified or not when going through it. It's really useful when doing a pre-job walkdown or to look an unfamiliar area over prior to going there.

Many plants produced something like the valve locator, but did not put it in a very usable format (e.g. some MAC fan wrote it on proprietary Apple software). Sequoyah has a decent product on MS Excel, which is backed up with the virtual tour.

Does anyone at a BWR-Mark 1 have a decent valve locator? (esp. one with instrument/transmitter locations &/or pictures)

We have a picture file, but it's kinda thin. We also use the time honored "go ask the old guy" method...... ;)

We have a pretty good valve and transmitters locater book with pics, for our containment and Auxiliary building at FPL one of our House RP updates as he goes along and it is the best i have seen. we recently performed some power entries (we had both our units RX heads replaced ) so with that we have updated our Neutron dose areas (maps etc ) to help with our historical data now This book is a great Alara concept and a tool to do the job right the first time.he has given copies of this book to workers new and old to our site. Even OPS uses it If you want to contact him email me and I can give you his name etc if you wish. BWR plants try the Entergy plants they had a good virtual tour and valve locator's contact their Alara Groups...

Thanks!

That's how the topic came up...Old Guy had his day off & we couldn't figure out where the jobsite was, let alone what we needed to do once we got there... :(

We have the virtual tour, but it's on an obsolete computer that only 3 people have access to. There is also a partial list of valves with locations & some pictures that we all have access to...guess we'll have to decide if it's worth adding to, or if it would be better to start fresh.
