"In this case, officials at the V.C. Summer plant learned about cracks in fuel pipes in the facility’s diesel generator system in 2003. Utility workers fixed the initial crack, as well as other cracks four different times in the years after the initial work was done. But the NRC says the utility never adequately assessed what could be done to make sure the diesel piping system did not experience more cracking. The most recent cracks were identified in November 2022 during a 24-hour test of the system. Workers found a small leak on one of two diesel generator systems. The leak increased over time and workers discovered a 140-degree crack around a pipe, records show."

So they found cracks first in 2003, and fixed them. They found more cracks over the years and fixed them... what they have failed to do is to stop the cracking from occurring in the first place. That failure led to an even bigger crack happening during a test run of the system. According to Dominion, they plan to build a new pipe, which should fix this. The NRC seems to think they should have done this sooner, and the NRC is likely right, but I am no expert in these things.

It probably should also result in a much more throughout inspection of the plant to ensure that there are no other issues. Again, I have no expertise here.

Agreed overall. That specifically contradict's GP's upthread understanding of "The original cracks were repaired. New ones did not show up until 2022."
