Abstract
The U.S. Nuclear Regulatory Commission (NRC) is issuing a new Regulatory Guide (RG) 4.27, "Use of Plant Parameter Envelope in Early Site Permit Applications for Nuclear Power Plants." This RG provides guidance for nuclear power plant applicants that elect to use the plant parameter envelope concept to assume certain design parameters for an early site permit application when a specific reactor technology has not been selected for a proposed site.
