If approved, the CP would authorize the construction of four Xe-100 small modular, high-temperature reactors that use solid tri-structural isotropic fuel and a helium gas cooling system. 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 nuclear power reactor facility. The NRC is granting the exemptions, and issuing the environmental assessment (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."}
