KAIROS POWER, LLC - PLAN FOR AN AUDIT OF THE HERMES CONSTRUCTION PERMIT PRELIMINARY SAFETY ANALYSIS REPORT CHAPTERS 4 AND 13 (CAC/EPID NO. 000955/05007513/L-2021-NEW-0011)
Applicant: Kairos Power LLC Applicant Address: 707 W. Tower Ave, Alameda, CA 94501 Plant Name(s) and Unit(s): Kairos - Hermes Test Reactor Docket No.: 05007513
Background:
On September 29, 2021, Kairos submitted a preliminary safety analysis report (PSAR)
(Agencywide Documents Access and Management System (ADAMS) Accession No. ML21272A375) in accordance with Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Domestic Licensing of Production and Utilization Facilities, as part of its construction permit (CP) application for the proposed Hermes test reactor. The U.S. Nuclear Regulatory Commission (NRC) staff is conducting a detailed review of the CP application. Two key references in the PSAR are technical reports associated with Chapter 4, Reactor Description, and Chapter 13, Accident Analysis. Technical report KP-TR-017, KP-FHR Core Design and Analysis Methodology, is referenced in PSAR Section 4.5, Nuclear Design, and KP-TR-018, Postulated Event Analysis Methodology, is referenced in Chapter 13. Because many of the assumptions and inputs used in the analyses in Chapter 13 are derived from Section 4.5 (e.g.,
reactivity coefficients, shutdown margin, etc.) these two sections are combined in this audit for efficiency.
Purpose:
The purpose of this audit is for the NRC staff to gain a better understanding of Chapters 4 and 13 of the PSAR, with an emphasis on documentation supporting technical reports KP-TR-017 and KP-TR-018. Observing the underlying documents associated with technical reports KP-TR-017 and KP-TR-018 support the staffs evaluation of the prescribed hypothetical fuel, Flibe, and vessel temperatures given in PSAR Figure 13.2-1 to help determine whether they are conservative and appropriate for use in the maximum hypothetical accident analysis described in PSAR Chapter 13. If the NRC staff identifies information that is needed to support a finding, Kairos will need to submit that information on the application docket.February 23, 2022 2
Regulatory Audit Basis:
The bases for the audit are the regulations of 10 CFR 50.34(a)(1)(i), 50.34(a)(4), and 100.11.
Regulatory Audit Scope
This audit will focus on information provided by Kairos on the online reference portal.
Information and Other Material Necessary for the Regulatory Audit
Documents associated with technical reports KP-TR-017 and KP-TR-018 which are referenced in PSAR Section 4.5 and Chapter 13, respectively.
Team Assignments
Jeff Schmidt Senior Reactor Systems Engineer, Audit Lead responsible for audit summary report preparation Sam Cuadrado Project Manager, responsible for audit logistics Ben Adams General Engineer Andrew Bielen Nuclear Engineer Alexander Chereskin Materials Engineer Michelle Hart Senior Reactor Engineer Ed Helvenston Project Manager Jason Schaperow Senior Reactor Systems Engineer Alex Siwy Nuclear Engineer
Additional audit team members may be added as needed.

Entrance Meeting February 28, 2022 (4:00-5:00 pm ET)
Exit Meeting August 31, 2022, or earlier
Audit meetings will take place in a virtual format, using Microsoft Teams or other similar platform. Audit meetings will be scheduled on an as needed basis after the entrance meeting and once the NRC staff has had the opportunity to read any documents placed in the online reference portal. The audit duration is anticipated to be approximately 6 months with activities occurring intermittently during that period. Informal interim reports on the status of topics being addressed by the audit will be provided to Kairos.
The audit period may be reduced or extended, dependent on the NRC staff and Kairos progress in addressing audit questions. Additional audit activities may be planned as necessary to support the NRC staffs understanding of information needed to complete the review of the application.
To improve the efficiency of the audit, Kairos and NRC staff discussed the use of an online reference portal, established by Kairos, that would allow NRC staff limited read-only access to the technical information provided by Kairos. Use of the online reference portal is acceptable provided that Kairos establishes measures to limit access to specific NRC staff (e.g., based on NRC e-mail addresses or the use of passwords which will only be assigned to NRC staff directly involved in the audit on a need-to-know basis), and to make the documents view-only (i.e.,
3 prevent NRC staff from saving, copying, downloading, or printing any documents). The conditions associated with the online reference portal must be maintained throughout the audit process. The NRC staff who should initially be granted access to the portal are those listed in the Team Assignments section above. As needed, the NRC audit project managers may provide Kairos with the names of additional NRC staff who are added to the audit team and should subsequently be granted access.
Special Requests None.
Deliverables At the completion of the audit, the audit team will issue an audit summary within 90 days after the exit meeting but will strive for a shorter duration. The audit summary will be declared and entered as an official agency record in ADAMS and be made available for public viewing.
