I live near the site (AFP 67) where they were developing the nuclear powered aircraft. The site currently is a fenced-off area in the middle of a National Forest. There are still radiation detectors mounted here and there around the area monitoring for who-knows-what since I don't think there are any materials left there, and haven't been for decades. They filled the entrance to the mostly-underground complex with concrete, there's not much to see above ground (and not sure there ever was much in the first place).
