Description / Abstract:

This standard1) provides criteria for the timely retrieval and the subsequent processing, handling, and storage of data obtained from nuclear power plant and non-power nuclear facility strong-motion analog and digital seismic instrumentation.2) Nuclear power plant seismic instrumentation requirements are specified in ANSI/ANS-2.2-2016 [1].3) Non-power nuclear facility seismic instrumentation, if required, is specified in facility-specific regulations, standards, and/or guidance documents.

This standard does not address the evaluation of nuclear power plant ground and structure motion and the criteria to determine whether earthquake ground motion at the site has exceeded the plant’s operating basis earthquake (OBE) ground motion. These topics are addressed in ANSI/ANS-2.23-2016 [2].

The principal function of the seismic instrumentation covered in this standard is to address issues that have a significant bearing on safety or mitigate the consequences of accidents that could result in potential off-site exposures. This standard does not address weak-motion instrumentation installed in some nonpower nuclear facilities to measure small-magnitude ground accelerations or velocities.

Purpose

The primary purpose of this standard is to provide criteria for retrieval, processing, handling, and storage of records from nuclear facility seismic instrumentation and to specify related activities such that a high quality standard is achieved in obtaining pertinent information from the seismic instrumentation to adequately support the decision making at power and non-power nuclear facilities following an earthquake event.

This standard is intended for use at land-based nuclear power plants and non-power nuclear facilities that deploy strong-ground-motion instrumentation. It can be used for guidance at other types of nuclear facilities.

The states of the practice for nuclear power plant strong-motion seismic instrumentation and for nuclear power plant response to an earthquake are provided in Refs. [1] and [2], respectively, and can be used as guidance in assessing existing or developing new requirements and guidance for non-power nuclear facilities.
