1 KAIROS POWER, LLC - HERMES PRELIMINARY SAFETY ANALYSIS REPORT PRE-SUBMITTAL AUDIT PLAN (CAC NO. 000431, 99902069; EPID NO. L-2021-LRN-0077)

APPLICANT INFORMATION Applicant:

Kairos Power LLC Applicant Address:

707 W. Tower Ave, Alameda, CA 94501 Plant Name(s) and Unit(s):

Kairos - Hermes Test Reactor Project No(s).:

99902069

Background:

Kairos Power LLC (Kairos) began pre-application discussions with the U.S. Nuclear Regulatory Commission (NRC) staff on their Kairos Power Fluoride-Salt-Cooled, High-Temperature Reactor (KP-FHR) in October 2018. In December of 2020, Kairos announced that the Hermes test reactor would be used to support future development of the KP-FHR. Over the past several years, Kairos has submitted several topical and technical reports that apply to both the Hermes, as well as the full-scale KP-FHR reactor. As discussed in meetings held on January 27, 2021 and March 3, 2021, Kairos plans to submit an application for a construction permit (CP),

including a preliminary safety analysis report (PSAR), for the Hermes test reactor in accordance with Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Domestic licensing of production and utilization facilities. This PSAR is expected to follow the guidance in NUREG-1537, Part 1, Guidelines for Preparing and Reviewing Applications for the Licensing of Non-Power Reactors, Format and Content (Agencywide Documents Access and Management System (ADAMS) Accession No. ML042430055).

Purpose:

Consistent with their significant pre-application engagement, Kairos volunteered for this audit to provide the NRC staff an opportunity to assess the readiness of the draft PSAR before it is formally submitted for the NRC staffs review. The audit will allow the NRC staff to (1) identify any required information that is missing from the application, (2) identify technical or regulatory issues that may complicate the acceptance or technical reviews of the application, and (3) become familiar with the content of the application, particularly in areas where Kairos plans to propose new concepts or novel design features. The NRC staff will summarize its observations related to items (1) and (2) in an audit report to be provided to Kairos, as discussed below.

2 Regulatory Audit Basis:

The bases for the audit are the regulations in 10 CFR Part 50, Sections 50.34(a), Preliminary safety analysis report, and 50.35, Issuance of construction permits.

Regulatory Audit Scope The NRC staff will use parts of NRCs Office of Nuclear Reactor Regulation (NRR) Office Instruction LIC-116, Pre-application Readiness Assessment (ADAMS Accession No. ML20104B698), as guidance for conducting this audit. This audit will cover all the chapters of the PSAR including appendices on the emergency plan and quality assurance plan. It will also include technical reports on core design and the transient evaluation model.

Information and Other Material Necessary for the Regulatory Audit The NRC staff requests that all the documents in the audit scope be provided by Kairos on the online reference portal.

3 Logistics Entrance Meeting August 11, 2021 Exit Meeting August 26, 2021, or earlier, Time TBD Audit meetings will take place in a virtual format, using Microsoft Teams, or via 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 review any documents placed in the online reference portal. The audit duration is anticipated to be approximately 3 weeks with activities occurring intermittently during that period. The NRC staff estimates that the level of effort for the audit is approximately 300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br />.

Special Requests The NRC staff requests that Kairos Power ensure that their technical staff are available to answer questions during the audit.
