This notice applies to UT/ORNL joint faculty and others who travel on ORNL funding, their supervisors, budget directors, business managers, and those who process travel that will be paid entirely by ORNL.

ORNL is changing travel software, which is not compatible with UT’s IRIS software.  Therefore, our process must change.

On August 1, 2019, ORNL will move to their new travel system.  Following are the changes:


  • ORNL cannot forward travel requests electronically to our IRIS system.
  • The UT department or traveler must create a travel request in IRIS, even for zero expense trips.
  • The UT traveler must also book travel through the ORNL travel system, and identify as a UT Employee in their system.
