ORNL is a U.S. Department of Energy (DOE) national laboratory and access to ORNL is controlled by DOE and DOE policies. Acceptance of an experiment proposal does not imply approval for access.
Access will be provided to the physical areas and information systems necessary for the conducting of your experiment. Access is dependent on the successful completion of required training and receipt of approval for access from the appropriate facility.
Please note, access to ORNL and user facilities cannot be granted until approval has been issued by the ORNL Guest Services Office. The processing times for approvals are shown in the table below.
| Status | Process Time |
|---|---|
| U.S. Citizens | 3-5 calendar days |
| Nonsensitive Country Foreign National Citizens | 15 calendar days |
| Sensitive Country Foreign National Citizens | 35-40 calendar days |
NOTE: Due to DOE requirements, prospective users who are citizens of, were born in, or are affiliated with (employed or sponsored by) any “state sponsors of terrorism”—as defined by the U.S. Department of State—require special approval by DOE Headquarters before being granted access to ORNL and its facilities. Such approvals, if granted, can require six months or more for processing. |
