N-725 Guideline for Design and Analysis of Nuclear Safety Related Earth Structures
|Publication Date:||1 January 1983|
The purpose of this standard is to describe parameters and present guidelines and criteria to be used in construction of those earth structures forming part of the ultimate heat sink or act to protect nuclear power plant sites from flood, storm surge or other types of natural or manmade extreme load phenomena. Such structures are identified as safety related (Seismic Category I) structures. Also included are earth structures required to maintain finished grade and ground contours at nuclear power plant sites.
Construction includes all administrative, quality assurance and regulatory requirements, material selection, design, installation, examination and monitoring associated with the safety related earth structures. Included in this standard are requirements for earth dams, dikes, baffles, breakwaters, seawalls, revetments, cut and natural slopes, retaining walls, and compacted fills, whether of natural or cement stabilized materials. It includes identification of design margins of safety.
