No worries - I'll have to ask a few old NRC buddies that were Navy. I'll never forget the first time I saw the dry cask storage at my first nuclear plant - we had 12 built, but were only using one at the time. It lit up bright white on the thermal cams, but there was no difference on the normal daylight cams.
I did cybersecurity for the plants, but there is a lot of crossover with physical security because of things like microwave security, special fencing, camera, iris scanners, x-rays and metal detectors - all stuff that is digital and could be abused by attackers to gain access or even simulate an attack in one area while actually attacking another. Even things like the night-vision scopes and binoculars, and electric safe combination locks are digital so I had to protect them.
I would attack them myself, research them via online sources and manuals, and figure out ways to protect via monitoring (data or camera) or special plugs that require special keys that would be put into any ports that allowed a serial or network connection. Look at the back of a PC sometime and notice all of the open ports that are digital (especially older PCs). I had to invent several blockers with security screws or tamper tape to be within NRC regs. If I was protecting a camera I would have to make sure another camera watched that and the one being protected could see the protector as well - circular logic at its best. If a spent fuel pool had a digital water level float or a digital thermometer (of course they did) they had to be protected to ensure level changes would be addressed immediately.
The worst part was protecting stuff like the tornado sirens everyone is used to seeing. Around nuclear plants they also sound for a nuclear incident, and they could be in the middle of a farmer's field. We didn't own the land but had to work on those alarms, so it would be important to meet the farmer so you didn't get shot wandering into his field. Fun Times...
