- Licensing coated cladding is separate from efforts to realize benefits.
- Several of the high-ranked mechanisms from the PIRT that are included in the ISG are believed to relate to improved performance due to the coating.

- Manufacturing
- Industry believes that standard 10CFR50 Appendix B quality control programs at fuel manufacturers are adequate to assure product performance for coated cladding
- Chapter 15 Impact
- Regulatory Changes for Increasing Burnup Limits Potential Areas of Scope Creep

- Appendix A Line 251 states that during a LOCA, multiple parameters may be impacted by chromium coated cladding as denoted in a table that doesnt exist.
- 50.46 Regulatory Limit
- The section should be revised to state that current 50.46 regulatory limit (1204 ºC / 17% ECR for uncoated cladding) can be applied on a conservative basis to coated cladding if supported by test data, and that if the applicant wishes to have a different licensing calculated ECR for the coated rod, then justification must be made.
