Don't you feel safe that this will stop nuclear leaking???

Here is the comment about the photo
"The component in the photograph is a circulating water box in unit 3 which is defueled (not operating). This is part of the system that takes in ocean water which is circulated through condensers and then returned to the ocean. This water is not radioactive. We identified a small leak in the water box and will perform maintenance per our scheduling process. In the meantime, plastic is in place to direct the water from the small leak to a drain. While this system is not needed while unit 3 is defueled, we do periodically circulate ocean water through the system and that's why we use the temporary plastic to route the water to a floor drain."

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.

The picture seems to fit the explanation and sounds reasonable.

Not intended to stop a leak just divert the water that is leaking to a drain until the leak can be repaired.

No, that’s completely unsafe. They need to use duck tape!

Obviously the people making some of the comments have never spent time with Navy Nuke MMs. Some of my guys could build a leak rig that would make Roman aqueducts look like a K-12 science project.
