Description / Abstract:

Applicability and Scope

This Standard has the same applicability as Chapter IV of Attachment 2 in DOE O 420.1C, i.e., it is applicable to all government-owned and government-leased nuclear and nonnuclear facilities and sites.

The provisions of this Standard apply only to new facilities and major modifications, unless triggered by periodic NPH assessment and upgrade requirements.

This Standard addresses the following NPHs: earthquakes, extreme winds (inclusive of tornado, hurricane, and extreme straight line winds), floods, lightning, precipitation (inclusive of snow, rain, and ice), and volcanic eruptions. Wild land fires that may result from certain NPHs are not addressed in this Standard; rather, they are addressed in DOE-STD-1066- 2012, Fire Protection.

Several other NPHs may require analysis and design consideration at certain sites, although no guidance for hazard analysis or design for these phenomena is provided in this Standard. These phenomena include drought, fog, frost, extreme temperatures, landslides, subsidence, surface collapse, uplift, and waterspouts. DOE and facility operators should discuss which, if any, of these phenomena need consideration, based on both site and facility characteristics.

Several documents have been referenced in this Standard, both for establishing or augmenting requirements and to provide guidance. Even though only the current versions of these documents have been cited in this Standard, the use of the applicable provisions in the latest version of a cited reference is preferable, but not mandatory, provided that the use of such a later version is consistent with other provisions of this Standard. Also, when an SSC is designed by mixing the provisions from two versions of a cited reference, the resulting design shall not be less conservative than that resulting from the application of the latest version alone.


This Department of Energy (DOE) Standard (STD)-1020-2012, Natural Phenomena Hazards Analysis and Design Criteria for DOE Facilities, provides criteria and guidance for the analysis and design of facility structures, systems, and components (SSCs) that are necessary to implement the requirements of DOE Order (O) 420.1C, Facility Safety, and to ensure that the SSCs will be able to effectively perform their intended safety functions under the effects of natural phenomena hazards (NPHs). This Standard also provides criteria and guidance for the use of industry building codes and voluntary consensus standards in the NPH analysis and design of SSCs in DOE facilities.
