ion 1, “Industry Guideline for Developing a Plant Parameter Envelope in Support of an Early Site Permit,” issued May 2012 (Ref. 4), describes the development and use of an ESP application from the industry’s perspective, including the development of a PPE to bound multiple reactor designs. The PPE in NEI 10-01 is an example of the parameters needed for a PPE. However, not all parameters apply to all designs and additional parameters may be needed depending on the reactor designs that the PPE is bounding. Purpose of Regulatory Guides The NRC issues RGs to describe methods that are acceptable to the staff for implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific issues or postulated events, and to describe information that the staff needs in its review of applications for permits and licenses. Regulatory guides are not NRC regulations and compliance with them is not required. Methods and solutions that differ from those set forth in RGs are acceptable if supported by a basis for the issuance or continuance of a permit or license by the Commission. Paperwork Reduction Act This RG provides voluntary guidance for implementing the mandatory information collections in 10 CFR Parts 50,52, and 100 that are subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et. seq.). These information collections were approved by the Office of Management and Budget (OMB), under control number 3150-0011, 3150-0151, 3150-0093, respectively. Send comments regarding this information collection to the FOIA, Library, and Information Collections Branch ((T6-A10M), U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, or by e-mail to Infocollects.Resource@nrc.gov, and to the Desk Officer, Office of Information and Regulatory Affairs, NEOB-10202 (3150-0011, 3150-0151,and 3150-0093), Office of Management and Budget, Washington, DC, 20503.
