Public Protection Notification The NRC may not conduct or sponsor, and a person is not required to respond to, a collection of information unless the document requesting or requiring the collection displays a currently valid OMB control number. DG-4029, Page-3 B. DISCUSSION Reason for Issuance The NRC staff developed this RG to provide guidance to ESP applicants on the PPE concept, which allows an ESP applicant to postulate certain generic design criteria in the ESP application when a specific reactor technology has not been selected for a proposed site. Background The NRC published Office of Nuclear Reactor Regulation Review Standard (RS)-002, “Processing Applications for Early Site Permits,” in May 2004 (Ref. 5 ) to provide guidance to the staff on the processing and review of ESP applications. After publishing RS-002, the NRC issued subsequent guidance in NUREG-0800 and updates to RG 1.206 that superseded portions of the guidance in RS-002. Accordingly, many sections of RS-002 contained outdated guidance that did not fully reflect the NRC’s implementation of a risk-informed, performance-based approach to licensing. However, the guidance superseding the outdated portions of RS-002 does not contain all of the PPE information in RS-002. The issuance of this RG allows the NRC staff to withdraw the outdated guidance in RS-002 while retaining the PPE information for future use by prospective ESP applicants. The Role of the PPE in the ESP Process An ESP is an NRC approval issued under 10 CFR Part 52, for a site for one or more nuclear power facilities. It addresses site suitability issues and environmental protection issues independent of the review of a specific nuclear plant design. Use of a PPE allows an ESP applicant to defer the decision of what design to build to the COL stage. The ESP application requires a determination by
