Technical and overview tours

Tours of NRRI's Duluth facility can be requested and scheduled any time. A general tour is appropriate for college-aged students and older and lasts approximately 45 minutes. (For other age groups, we can discuss other options.) Technical tours that include in depth discussion on a particular topic with a researcher can also be arranged. Tours of the Coleraine Labs requires special coordination.
