ANS 2.10-2017 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. Nuclear power plant seismic instrumentation requirements are specified in ANSI/ANS-2.2-2016. 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. 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 non-power nuclear facilities to measure small-magnitude ground accelerations or velocities.

ANS 2.2-2016 specifies the required earthquake instrumentation at the site and on Seismic Category I structures of light-water-cooled, land-based nuclear power plants. It may be used for guidance at other types of nuclear facilities. This standard does not address the following: 1. instrumentation to shut down a nuclear power plant automatically at a predetermined parameter of the ground motion or the in-structure response; 2. procedures for evaluating records obtained from seismic instrumentation and instructions for the treatment of data. These procedures and instructions are specified in ANSI/ANS-2.23-2016; 3. instrumentation for nuclear power plant designs incorporating base isolation techniques.
