2. Technology Assessment Criteria
Critical flaws
Fundamental process
Materials
Technology development needs
Data needs/cost
Confidence in design basis
Major risks
Implementation
Operation

3. EPRI Criteria Economics Public Acceptance Regulatory Simplicity
Need to prioritize
Choices determined by primary issues

4. Critical Flaws Fundamental Process Materials
Combination of operating conditions at design point demonstrated at ITER
Large number of variants not demonstrated
System control mechanisms are critical
May not be economic to obtain complete design data
Materials
Component life central concern
New material compositions need long term data which may not be available to support design
Lifetime after radiation exposure uncertain

5. Technology Development
Relies on large scale, expensive facilities
Limited scope of data in relevant conditions
Long list of data needs covered by speculative relationships
Difficult learning period from plant to plant experience (long lead times, $$$)

6. Major Risks Implementation Regulatory Public Acceptance/risk taking
Private participation/risk taking
Supply chain
Completion
Cost/schedule growth

7. Major Risks Operation Capacity Forced outages Scheduled outages
Maintenance/repair cost
Regulatory changes
Early end of life
End of life costs
