FLEX concept for US-ABWR extended loss of AC power events
The US-Advanced Boiling Water Reactor (US-ABWR), certified by the USNRC, is a third generation, evolutionary boiling water reactor design which is the reference for the South Texas Project Units 3 and 4 (STP3&4) Combined License Application (COLA) and incorporates numerous design and technology enhancements for improved safety performance. Nuclear Innovation North America (NINA) is the License Applicant for this new build project, and Toshiba is the selected primary technology contractor. The STP3&4 project has finished the USNRC technical review of the COLA, and the final safety evaluation report (FSER) is scheduled to be issued by the USNRC in 2015. This paper summarizes the progress of the US-ABWR in licensing the FLEX Integrated Plan for the project, and describes the technology and features of the US-ABWR design that contribute to safety post-Fukushima. It also provides an informational comparison of the design capabilities of the US-ABWR for extreme external events, and relates these capabilities to re-assessments performed for the Laguna Verde site following the Fukushima event.
