Nuclear Regulatory Commission September 5, 2024 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is issuing an environmental assessment (EA) and finding of no significant impact (FONSI) regarding the NRC's consideration of issuance of a construction permit (CP) to Kairos Power, LLC (Kairos, the applicant) for the proposed Hermes 2 test reactor facility located in Oak Ridge, Tennessee. If approved, the CP would authorize the construction of two fluoride-salt cooled, high- temperature reactors that use solid tri-structural isotropic fuel in pebble form, intermediate liquid-sodium loops, and a common power conversion unit. In addition, the NRC is issuing exemptions from certain NRC requirements which state that the NRC staff shall prepare and issue an environmental impact statement (EIS) to support the issuance of a CP for a testing facility. The NRC is granting the exemptions and issuing the EA and FONSI concurrently to satisfy its obligations under the National Environmental Policy Act of 1969 (NEPA) and requirements under NRC regulations, related to the proposed action.

The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its spent fuel regulations by revising the Holtec International HI-STORM 100 Cask System listing within the "List of approved spent fuel storage casks" to include Renewed Amendment No. 18 to Certificate of Compliance No. 1014. Renewed Amendment No. 18 would amend the certificate of compliance to incorporate the Holtec Report No. HI- 2200343-A entitled, "Topical Report for Allowance of Heat Load Patterns in HI-STORM 100 and HI-STORM FW Systems."
