It’s runtime. Most systems on a submarine never stop. The reactor stuff may get shut down in port, but we bring on shore power and everything else stays on. It never turns off. After a decade, stuff is getting old. Then it’s just a constant battle against stuff breaking. There is plumbing everywhere. Thousands and thousands of valves. They go bad. Pumps go bad. Motors go bad. Electronic boards burn out. Hydraulics leak. It’s never ending. Just the way it is with something so complex that operates in such tough environment. The ocean never gives up trying to get in. A void space in the water is unnatural. Nature never gives up trying to restore things.
