Published By:ASME International (ASME)
This Standard is intended to be used in conjunction with ANSI N45.2 and addresses the quality assurance requirements related to subsurface investigations performed prior to the construction of safety related structures of nuclear power plants.
The requirements of this Standard apply to the work of any organization or individual participating in subsurface geotechnical investigations such as drilling, coring, sampling, trenching, logging, geophysical methods, or testing or in interpreting results of subsurface investigations. This Standard is intended to apply to any of these activities which will be used to formulate design bases for the plant. The extent to which the individual requirements of this Standard apply will depend upon the nature and scope of work to be performed and the importance of the item or service involved.
