“Dear PoPville,

What the Helen of Troy is This? Update.

Demo nuclear reactor has gone vertical at 10th and V… not looking very temporary anymore ☢️”

“It’s just an inert nuclear model” is exactly what someone would say who plans to bring a small thermonuclear device into the nation’s capital before “leaving town for a conference.”
