Two thoughts:
1. The unmanned guard booth was probably an abandoned relic of a security plan that existed before HD cameras were available.
2. The utility probably kept it in place so that if there was ever a major event, they could man it to keep the media out.
Notice the lefty academic failed to cite a violation of any particular security rule - he and the willing and eager “reporter” simply dropped ominous vague hints. Surprised the “reporter” bothered to mention the actual distance from their deepest “penetration” to the reactor.
Security rules for all nuclear plants are the same. This article is very misleading, the key words are “ visitors parking lot”!
