In September and October 2021, Kairos Power submitted a Construction Permit Application (CPA) for the Hermes non-power reactor, including a Preliminary Safety Analysis Report (PSAR) (Reference 1) and an Environmental Report (ER) (Reference 2). Subsequent to the initial submittal of these documents, Kairos Power made a decision to reduce the Hermes operating life from 10 years to 4 years. This change has a negligible impact on the CPA but has a minor effect on content in Chapters 1, 2, 4, 9, 13, and 15 of the PSAR and Chapters 2, 4, and 5 of the ER. Kairos Power requests NRC review of these changes as part of continued review of the Hermes CPA.

Changes to the pages of the PSAR affected by this decision are provided in Enclosure 1. Changes to the pages of the ER affected by this decision are provided in Enclosure 2.

This change also impacts two topical reports referenced in the CPA that are currently under review by NRC staff, KP-TR-014 (Reference 2) and KP-TR-013 (Reference 3). Kairos Power will provide updates to these reports as part of changes to these documents that are occurring as part of their review process.
