Upon Arrival

Upon Arrival

Pick Up Badge – The Chestnut Ridge Visitors Center is conveniently located in building 8600 for intermittent Facility User and Visitor badge pick up.  Foreign nationals are required to provide their passport and visa, including I-20 document or Legal Permanent Resident (LPR) “green” card, if applicable. The Visitor Center Hours: Monday through Friday, 7:30 a.m. – 4:00 p.m. 

Effective April 1, 2023:  A policy change made by the Department of Energy may affect your method of arrival, departure, and food deliveries. The change to DOE Order 142.3B (Unclassified Foreign National Access Program) means that delivery drivers (of taxis, Uber, Lyft, DoorDash, and the like) must be US citizens or non-US citizens with a valid ORNL badge to enter the campus. Those not meeting this criterion will not be allowed through the security checkpoint.

When calling for a taxi/other driver delivery service or ordering a food delivery, we kindly ask you to verify that the driver will be a U.S. citizen or has a valid ORNL badge to prevent delays or entry failures. We have notified area taxi services of this policy change, but have no way to communicate with services like Uber, Lyft, etc.

Hours of Operation

The CNMS is committed to providing its users with routine access to its facilities and instrumentation, as well as technical assistance when needed, during the Operating Hours listed below except on ORNL-wide holidays. Users are expected to schedule their work in advance in consultation with collaborating CNMS staff, and to recognize that individual staff members may have other obligations at specific times, but the intent is that someone will be “on-call” to assist users during these hours. Similarly, facilities and instrumentation may be reserved at specific times during these hours for maintenance or upgrades and for the conduct of CNMS-sponsored research but every effort will be made to give priority in scheduling to CNMS users during these operating hours.

Longer hours may be possible for certain facilities on an occasional basis, but only if special arrangements are made in advance. Such requests may be granted on a case-by-case basis subject to user proficiency and availability of equipment and staff.
