Abstract

The APR1400 (advanced power reactor, 1,400 MWe) is a standard advanced evolutionary light water reactor (ALWR) in the Republic of Korea. It is now under construction as Shin-Kori units 3 and 4. The APR1400 is designed with an additional safety margin to improve the protection of the public health, mainly focusing on typical initiators such as transients and small-break loss-of-coolant accidents (LOCAs) as well as safety against severe accidents. This section outlines the major mitigating design features of severe accidents, summarizes the results of the full-scope PSA, and presents the main results of a deterministic evaluation of severe accident issues. The APR1400 design is robust and capable of mitigating the consequences of a wide spectrum of severe accident scenarios while maintaining containment integrity and minimizing radiation release to the general public.
