ARIES Pathways Program

• Industrial Advisory Committee
• Preliminary Comments
• R W Kuhr
• June 14

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
• 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
