ANS 2.2 – Earthquake Instrumentation Criteria for Nuclear Power Plants

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.
