RE: Transmittal of NRC Staff Draft Safety Evaluation Regarding Kairos Power Graphite Materials Qualification Topical Report CAUTION: This email originated from outside of the organization.

Hello Margaret, On December 19, 2022, we conducted a MS Teams call to clarify some of the information included in the safety evaluation (SE) for the Kairos Graphite Materials Qualification topical report (TR), and also discuss the next steps in preparation for the meetings with the ACRS.

During this call you confirmed verbally that the SE did not contain proprietary information that was not properly marked/bracketed in the document. We are currently preparing the final SE for

this TR and the transmittal letter, and we will require a written confirmation, via email, indicating the results of your proprietary information review for the then draft SE.

Please respond to this email with your confirmation. Should you have any questions feel free to contact me at your earliest convenience.

Thank you, Richie Richard Rivera, MEM Project Manager U.S. Nuclear Regulatory Commission - HQ NRR/DANU/UAL1 Ph. 301-415-7190 E-mail Richard.Rivera@nrc.gov Please consider the Environment before printing this e-mail.
