SUMMARY

OF MEETING HELD WITH TRISO-X LLC TO DISCUSS OBSERVATIONS AND THE FUEL FABRICATION PROCESS ON JANUARY 10, 2023 The U.S. Nuclear Regulatory Commission (NRC) hosted an observation meeting that was part open and part closed with TRISO-X, LLC (TRISO-X) on January 10, 2023. The meeting consisted of three sessions including a public session from 9:30-10:00 am, a closed session from 10:00-11:30 am, and a closed session from 1:00-5:00 pm. In the morning sessions, the NRC staff discussed with the TRISO-X staff a number of observations regarding the license application. These observations were provided to TRISO-X in advance via letter dated December 16, 2022 (Agencywide Documents Access and Management System [ADAMS]

Accession No. ML22348A013).

The afternoon session consisted of the TRISO-X staff providing an overview of their proposed fuel fabrication process. TRISO-X will receive high assay low enriched uranium enriched to less than 20% U-235 in the form of uranium oxide (U 3O8) from a supplier that is still to be determined. They will process the uranium into triple-carbon coated microspheres. Multiple thousands of microspheres will be compressed into a fuel pebble or fuel compact. These fuel pebbles or compacts will be collected into approved containers prior to shipment to an advanced reactor. The presentation identified the major steps in the process and the systems important to safety. TRISO-X provided the slide presentation in advance of the meeting which was placed in non-public ADAMS due to proprietary and security related information (non-public, ML22336A218).
