2. The Most Negative EOL Moderator Temperature Coefficient Limit Report (as found in Appendix D of WCAP-13749-P-A).

This information will be provided to the NRC staff no later than 60 days after the performance of the conditional EOL MTC elimination determination for the next three uses (i.e., fuel cycles) of this methodology.
