Use of Plant Parameter Envelope in Early Site Permit Applications

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft regulatory guide (DG), DG-4029, "Use of Plant Parameter Envelope in Early Site Permit Applications." DG-4029 is a new regulatory guide that proposes guidance for nuclear power plant applicants that elect to use the plant parameter envelope (PPE) concept to assume certain design parameters for an early site permit (ESP) application when a specific reactor technology has not been selected for a proposed site. It incorporates the PPE portions of NRC Review Standard (RS)-002, "Processing Applications for Early Site Permits." The issuance of this DG allows the NRC staff to withdraw the outdated guidance in RS-002 while retaining the PPE information in it for future use by prospective ESP applicants.
