Fuel Cycle and Transportation of Fuel and Waste Evaluation -

Acceptance Criteria for the Kairos Review Donald Palmrose, PhD Senior Reactor Engineer Environmental Center of Expertise Division of Rulemaking, Environmental, and Financial Services Office of Nuclear Material Safety and Safeguards

2 August 19, 2021 Acceptance/Review Criteria Considerations for the Kairos Hermes Review

• Limited publicly available non-LWR information Rationale for two PNNL reports (ML20267A217 and ML20267A157)

• Portions of prior NEPA assessments should apply

• Additional assumptions considered in development of the draft ANR GEIS (est. publishing date in May 2022)

• Should help inform the Kairos Hermes environmental review

3 August 19, 2021 Fuel Cycle Assumptions

• Table S-3 is expected to bound front-end impacts for ANR fuels:

Increasing use of in situ leach uranium mining Current light-water reactors are using nuclear fuel more efficiently Less reliance on coal-fired electrical generation plants Transitioning of U.S. uranium enrichment technology from gaseous diffusion to gas centrifugation

• Waste and spent fuel conditions should not be significantly different from NUREG-2157 For example, assuming once-through fuel cycle for TRISO

• Must satisfy the regulatory requirements of 10 CFR Parts 40, 70, 71, and 73

4 August 19, 2021 Fuel Cycle Verification

• Verify the following:

Fuel fabrication source Anticipated levels of fuel burnup Waste and spent fuel conditions bounded by NUREG-2157 Meet 10 CFR Parts 40, 50, 70, 71, 72, and 73

• Confirm if TRISO fuel fabrication has similar impacts as existing fuel fabrication (e.g., performed under existing license)

• Check for missing information using PNNL-29367 Rev. 2, Non-LWR Fuel Cycle Environmental Data (ML20267A217)

5 August 19, 2021 Transportation of Fuel and Waste Assumptions

• Consideration of prior staff assessments such as the Clinch River ESP FEIS analysis Could bound ANRs if similar to conditions in past new reactor EISs

• For the draft ANR GEIS, the staff compiled information from the prior new reactor transportation of fuel and waste impacts

• Believe total annual shipment distances are a good indicator of impacts based on:

Review of 15 new reactor ESP and COL EISs Number of shipments normalized to net electrical output of 880 MW(e) from WASH-1238 (see RG 4.2 Rev 3 Section 6.2.2 for details)

One-way and two-way distances where appropriate

6 August 19, 2021 Transportation of Fuel and Waste Verification

• Verify the following:

Were prior new reactor analyses relied upon Were certified transportation packages cited Is the Fuel fabrication source and are potential LLRW and spent ANR disposal or away-from-reactor sites provided in the ER Are TRISO release fractions available or can assumptions be applied Can maximum annual one-way and two-way shipment distances can be determined from information in ER

• Based on the outcomes above, may have to consider a full description and detailed analysis See RG 4.2 Rev 3 Section 6.2 and PNNL-29365, Transportation of Fuel and Wastes to and from Non-LWRs (ML20267A157)
