Having been a steamfitter in my past life and working at oil refineries, nuke plants, and other chemical facilities, my question is this pipe on the nuclear (radioactive) side of the plant or the non-nuclear side?
If it is fresh coolant water on the supply side it is only water and is a minor issue unit the next schedule outage when the gaskets can be replaced and flanges re-torqued.
I was working on the then named WPPSS Plant 2 and we were installing a new piping system in the coolant water pump house that was going to be completely under water upon completion. This was 6 foot diameter pipe and, contrary to popular belief, was not perfectly round which led to hi-lo mismatch when fitting the pipes together to be welded. We had a disgruntled fitter who was going to be laid off so he contacted the site NRC Rep to tell him of this issue to save his job.
When the NRC Rep showed up with a few others in tow he asked to see the issue which we chowed him. And then the piping superintendent looked right at him and asked the question: Are you afraid of water leaking into the pipe or out of the pipe? NRC Rep left and so did the fitter.
Bottom line is if it only water, regardless of which side it is on, and only a minor leak, which this appears to be just a dripping issue, it can wait until the next outage versus taking the plant down, reporting it as an unplanned shutdown, losing generation during repair, and then going through the re-start process.
How are we going to defeat nuclear power if people like you keep making sense?
