SMART is a 300 MWt/100 MWe integral-type PWR designed by KAERI in the Republic of Korea. SMART incorporates inherent safety features such as the integral configuration of the reactor coolant system, its improved natural circulation capability, a passive residual heat removal system and an advanced LOCA mitigation system. SMART has a low power density core that uses 5 w/o UO2 and results in a thermal margin of more than 15% to accommodate any design basis transients with regard to the critical heat flux. SMART has been conceived as a multipurpose energy source including non-electric applications such as seawater desalination, district heating or other industrial applications.
