  1. 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
