KAIROS POWER, LLC - HERMES 2 ENVIRONMENTAL REPORT AUDIT PLAN (CAC NO. 000955, 05000611 and 05000612; EPID NO. L-2021-NEW-0012)
APPLICANT INFORMATION:
Applicant:
Kairos Power, LLC Applicant Address:
707 W. Tower Ave, Alameda, CA 94501 Plant Name(s) and Unit(s):
Kairos - Hermes 2 Test Reactors Docket No(s).:
05000611 05000612
Background:
By letter dated July 14, 2023 (Agencywide Documents Access and Management System (ADAMS) ML23195A121), Kairos Power LLC (Kairos) submitted an Environmental Report (ER) in support of a construction permit (CP) application for the Hermes 2 test reactor project. By letter dated September 11, 2023, the U.S. Nuclear Regulatory Commission (NRC) notified Kairos of its acceptance of the CP application for detailed review (ML23233A167). The staff is reviewing the information in the ER (ML23195A125) per Title 10 of the Code of Federal Regulations (10 CFR) Part 51. The staff is preparing an Environmental Assessment (EA) in accordance with 10 CFR 51.30 to evaluate the environmental impacts from the proposed action.
Additionally, the staff is pursuing an exemption to 10 CFR 51.20(b)(1), which requires preparation of an environmental impact statement (EIS) for issuance of a permit to construct a nuclear power reactor, testing facility, or fuel reprocessing plant under 10 CFR Part 50.
In its initial review of data and information within the corresponding context of the ER, the staff has identified information needs (Attachment 1) that would promote a better understanding of the detailed analysis and bases underlying the construction permit application. This environmental audit will provide the NRC staff an opportunity to discuss these items with the applicants subject matter experts, staff and contractors. During the audit, the staff will discuss environmental matters related to the site and technical area such as land use, air quality and noise, ground and surface water, terrestrial and aquatic ecology, historical and cultural resources, socioeconomics and environmental justice, human health, radiological and non-radiological waste, fuel cycle, transportation of radioactive material, postulated accidents,
2 cumulative impacts, and alternatives to the proposed action. The audit will allow the staff to better understand the site, environmental interfaces of the project, and modeling results needed to draw appropriate environmental findings.
Purpose:
The NRC staff is conducting an environmental audit of the ER submitted by Kairos for the proposed Hermes 2 test reactors (ML23195A125), to seek clarification, improve understanding, and to verify information provided in the ER and supporting documentation.
Regulatory Audit Basis:
Requirements for environmental reports supporting construction permits are specified in 10 CFR 51.50, Environmental Reports - construction permit, early site permit or combined license stage. The ER for the Hermes 2 construction permit application follows the guidance in Chapter 19 of the Final Interim Staff Guidance (ISG) Augmenting NUREG-1537, Part 1, Guidelines for Preparing and Reviewing Applications for the Licensing of Non-Power Reactors, Format and Content (ML12156A069).
Regulatory Audit Scope:
Audit team members will review documents and other requested information outlined in the information needs list (Attachment 1). This list covers those environmental review areas outlined in the Background section of this audit plan. Attachment 2 lists those areas for which pre-arranged audit discussions will be worked out between the NRC and Kairos project managers to take place the first week of the audit (see discussion below for audit logistics.)
Environmental Review Team Table 1 is a list of the NRCs environmental review team assigned to the Kairos CP review and their role or review area, which includes NRC and staff and their contractor. Additional NRC staff may participate in some audit discussions based on coordination with related reviewers (see Attachment 2).
