MotivationMotivation• Safe, economical processing is
crucial to the success of fusion energy devices.
• At ≈ $3/Ci - $8/Ci one kg of T cost ≈ $29M - $78M. Perhaps more.
• Processing plasma exhaust has been demonstrated in an operational fusion environment (TFTR, JET).
• Deliver T (and D) back to target manufacturing in a timely manner.
• Closing the fuel loop in IFE reduces external handling (DOT 49 CFR) and burial site issues in support of a lower operational inventory.
Requirement Action
Design a closed loop tritium processing/recycling facility (for ≈ 25 kg/y T throughput) IFE plasma exhaust system
• A conceptual design for such a system is being investigated for required operational parameters
Design a safe, economical system which processes plasma exhaust that will return high purity T and D back to target fueling system with accurate inventory control
• Incorporate COTS components, proven processing technology experience, and safe handling procedures in the CDR
Develop an operational strategy which minimizes at risk tritium for technical and regulatory classification consideration(s)
• All system flows will be analyzed and modeled to maintain inventory at economical levels in support of machine operation. Propose a ramp up (nuclear fuel usage) strategy
