You were not at the facility.
You are a moron.
I am a mechanical engineer, with a degree from UT Austin, specializing in power plant systems.
I used to work For Westinghouse and before that I worked at Comanche Peak, Dresden, Laguna Verde, Angra, Davis-Besse, Perry, Beaver Valley, Robinson, and Cooper plants. After starting with Westinghouse, I've been at South Texas, Wolf Creek, Fort Calhoun, San Onofre, Waterford, and Prairie Island.
I've worked in operating nuclear plants with full unescorted access to the whole plant for extended periods ranging from weeks to decades.
You took a tour and now consider yourself an expert. Take a hike.
