It's hardly forgotten or unknown. You can still see parts of the facility where the US nuclear powered aircraft was being developed at an abandoned Lockheed site in the Dawson Wildlife Management Area in Dawson County, Georgia, near Dawsonville. There are still buildings there, fenced off with chain-link (though easily to get around and through) and still with the nuclear warning symbol painted on the sides of the buildings.
Many thousands of people go there every year to locate the site, and to go horseback riding, hunting, 4-wheeling, hiking, birdwatching, do photography, etc. - even gold prospecting (the first major gold strike in the US in the 1800s was a few miles away). There are geo-cache sites for people into that kind of exploring. It's only a few miles from the southern terminus of the Appalachian Trail near Amicalola Falls in Dawson County.
(But if you hear banjo music... )

No radiation danger? What IF the uranium type reactor was breached during a bomber crash. It still would contaminate the area around the crash site.
I doubt that such a reactor wouldn't use weapons grade materials. Most likely the nuclear materials would be quite similar to commercial grade fuel rods.
Even with lead shielding around the nuclear reactor the crew would possibly be exposed to radiation, particularly Gamma and neutron rays.
The idea of a nuclear bomber is not a good one.
