Yeah, though this dates back to a time when not joining the NPT was seen as controversial (there was a diplomatic fuss at the time, and a lower level fuss some decades later when India started developing weapons while remaining out of the NPT). At the time the US insisted on carrying out inspections of the Negev facility to ensure that weapons were not being developed. In the event they eventually stopped as they felt that their inspections were not particularly effective.
