As long as the reactor coolant pumps are running, they do kinda have an unlimited supply of cooling water…
But that’s mostly a funny, because after we discuss the overall GPM of those pumps (mind-blowing, like most everything else on a nuclear carrier scale is) I have absolutely zero understanding of their operation. I didn’t have to wear a TLD “most” of the time, and even when I did, it was barely above the ship’s baseline.
That TLD comment is in complete contrast to when I was a radiographer in oil & chemical plants for NDT… I worked with some guys who for their New Year’s resolutions would start a betting pool on who could catch the most… some of them topped 15 Rads over the whole year. After 2.5 years, I had matured enough to realize they were nuts and would likely end me up with irreversible damage or federal charges. So I went to Purdue for a BS ECET & MS Tech. Safer that way
