TRISO Fuel Fabrication Overview HALEU Needed in Oxide Form U3O8

TRISO-X Pilot Facility TRISO-X Pilot Facility inside ORNL, public/private partnership with X-energy engineers Ability to produce HALEU fuel elements

Key Milestones for TRISO-X TRISO-X Press Releases X-energy Dedicates TRISO-X Fuel Fabrication Pilot Line at ORNL February 27, 2019 X-energy Invited to Submit Part II for DOE Loan Guarantee Application March 14, 2019 X-energy and Global Nuclear Fuel Announce TRISO Fuel Collaboration November 6, 2019 Congressman Chuck Fleischmann Participates in Dedication with X-energy and ORNL Leadership

The Cross-cutting TRISO-X Fuel Fabrication Facility

HALEU Needs and Challenges

Need HALEU supply chain that mirrors LWR LEU supply chain 3/4Mining Conversion Enrichment Fuel Fabrication

Transport package 3/4Production of HALEU is not enough, need NRC approved packages to move material domestically and internationally

NCS code validation for fuel fabrication 3/4X-energy well along the way to V & V of NCS evaluations of equipment and facility layout

Cost 3/4Having a complete supply chain in place is a must, but not sufficient to ensure deployment 3/4Costs must NOT be prohibitive 3/4On-line calculators are probably unreliable for determining HALEU $ EUP

TRISO-X FFF Conceptual Design Complete X-energy will receive a Part 70 Cat II SNM license amendment from the NRC TRISO-X FFF:

9Modular/Scalable design 9Already pilot level proven 9Lean, NCS compliant layout 9Adaptable to multiple fuel forms.

9Licensing activities underway 9 NCS, PHA, ISA all under NRC approved regulations 9 Designed to 5 MTU capacity to allow Xe-100 expansion and HALEU demand First US NRC CAT II Facility NU to 20% enriched U

Design and HALEU NCS Licensing Status Over 200 design docs/drawings to date

~45 engineers dedicated to Prelim Design

HALEU is the key to deployment of ALL advanced reactors

A HALEU fuel cycle must be created 3/4 Enrichment 3/4 Deconversion 3/4 Fuel fabrication 3/4 Transport

X-energy has addressed HALEU fuel fabrication with the TRISO-X Fuel Facility

NCS and physical security for CAT II facilties underway

X-energy supports DOEs HALEU enrichment project in Piketon OH

Transportation packages must be addressed

Minimum of 4-6 MTU needed by 2023, if not sooner

Advanced reactor design funding is useless without a supporting fuel cycle
