DOE-STD-1021-93 (W/ CHANGE-1 AND ERRATA APR-2002), DOE STANDARD: NATURAL PHENOMENA HAZARDS PERFORMANCE CATEGORIZATION GUIDELINES FOR STRUCTURES, SYSTEMS, AND COMPONENTS (JUL-1993)

DOE-STD-1021-93 (W/ CHANGE-1 AND ERRATA APR-2002), DOE STANDARD: NATURAL PHENOMENA HAZARDS PERFORMANCE CATEGORIZATION GUIDELINES FOR STRUCTURES, SYSTEMS, AND COMPONENTS (JUL-1993)., Change Notice #1 was included in this standard to provide information to help meet the requirements in DOE Order 420.1 and its associated Guides, and to update this standard to the most current references. This DOE standard is approved for use by all departments and contractors of the Department of Energy (DOE). This standard will still apply if and when DOE Order 420.1 is converted to a rule. In addition, this Standard will still apply when other referenced Orders are implemented by the 10 CFR Part 830 . This standard provides guidelines to be used for Natural Phenomena Hazard (NPH) performance categorization of structures, systems, and components (SSCs), and recommends systematic procedures to implement these guidelines. It applies to all Department of Energy (DOE) facilities that are covered by DOE Order 420.1. 10 CFR Part 830 requires the use of a "graded approach" in performing safety analysis and evaluation of DOE facilities for normal operating and accident conditions, including accidents caused by NPH events. The NPH Guide to DOE Order 420.1 (DOE G-420.1-2) uses this "graded approach" and requires, for the purpose of NPH design and evaluation, placing the SSCs comprising the DOE facilities into five NPH performance categories. NPH performance categorization guidelines provided in this technical standard are based on the system safety classification and hazard categorization/classification data obtained from the application of 10 CFR Part 830, DOE-STD-3009-94 (CHG-1), and DOE-STD-1027-92. There is an established hierarchy in the set of documents that specify NPH requirements. In this hierarch, 10 CFR Part 830 is the highest authority followed by DOE O 420.1. The next sets of controlling documents are the associated guides DOE G 420.1-1 and 420.1-2 followed by the set of NPH standards. In the event of conflicts in the information provided by these documents, the information in the document of higher authority should be utilized (e.g., the definitions provided in the guides should be utilized even though corresponding definitions are provided in the NPH standards).
