Spent Fuel Pool Instrumentation Design
(OP)
Hello Gentlemen,
I am a Welding Inspector.
My shop has a potential client that is looking to have us weld components for
Spent fuel pool water level instrumentation.
I am concerned that we are lacking acceptance criteria.
Can anyone provide direction in regards to specs or standards dictating weld design & acceptance criteria for this application?
Any guidance with this is greatly appreciated.
Also, many thanks to all who participate in the discussions on this site. It has been the source of answers to many of my questions.

That you would be expected to (required to!) research all the potential "strings" and "straightedges" is an extra expense that you need to be reimbursed for (either in your original bid, in the time and margins reasonable for the job that you include in this bid) or in a bid phase of the whole job separately paid for by them, or as a longer-term consulting and agreement contract. It is, however, to their benefit to have you suck up all of the costs in researching their needs - which they themselves may not know! - and have you do it for free. And then have somebody else do the simple job or welding the steel. Cheaper.
Be careful of your terms, conditions, proprietary data clauses, future contract assumptions, etc.

Almost certainly NOT. Anything that close to spent fuel requires 'Seismic Criteria'. Remember all the pipe support reinspections 'way back when', when NRC finally acknowledged that failure of supports during an earthquake would cause major safety problems? There were a BUNCH of supports and other items that were not pressure-boundary items that had to be rewelded or rebuilt. Because if that little support broke, it would smash a lot of critical equipment.

Thx much for the input.
Racookpe1978,
My spider senses & most of the codes I use were telling me the same information. Eng.g will dictate requirments.
We politely no bid the work.
Thanks as always for the sage advice.
