Savannah River Site Seismic Qualification Program boundary selection

The Savannah River Site Seismic Qualification Program utilizes methodology developed by the Seismic Qualification Utilities Group and endorsed by both the Nuclear Regulatory Commission and the Department of Energy. The systems selected for seismic upgrade prior to restart will ensure that following a seismic event, the reactor can be safely shut down, decay heat removal can be maintained, and the reactor status can be monitored for a minimum of seventy-two hours. Systems selected were reviewed to establish the boundaries of seismic qualification. Program implementation is being conducted in two phases. Phase on will be conducted prior to restart. It will include evaluating accident prevention systems and selected monitoring and mitigation systems and upgrading as necessary to ensure compliance with DOE requirements. Phase two will evaluate/upgrade other mitigation systems after restart to provide enhanced assurance of reactor safety
