Anybody have any info on getting Mini-messs sample valves installed in a Nuclear plant? We would like to install them at our plant. the problem is: Any change to equipment configuration requires mass amount of paper work.

Get in touch with the guys at Schematic Approach. They have solutions for all sorts of situations where sampling is required.

I work at a nuke plant. We had a similar situation when installing grease reliefs. Design Engineering was able to issue one design change package which covered all non-safety applications. Installation was then under Maintenance control.
