SMART (Korea Atomic Energy Research Institute, Republic of Korea) [Passive Safety Systems in Advanced Small Modular Reactors]

The SMART (System Integrated Modular Advanced Reactor) is an advanced pressurized light water reactor that is being continuously studied at KAERI (Korea Atomic Energy Research Institute) with a rated thermal power of 330 MW. The reactor is proposed to be utilized as an energy source for sea water desalination as well as for small scale power generation. Advanced technologies such as inherent and passive safety features are incorporated in establishing the design concepts to achieve inherent safety, enhanced operational flexibility, and good economy. The SMART is designed to supply 40000 tons of fresh water per day and 90MW of electricity to an area with an approximate population of 100000 or an industrialized complex. In order to demonstrate the relevant technologies incorporated in the SMART design, the SMART-P (i.e. a pilot plant of the SMART) project is currently underway at KAERI. SMART received standard design approval (SDA) on 4 July 2012. The prominent design feature of SMART is the adoption of integral arrangement. The major components of the NSSS such as the core, steam generators, main coolant pumps, and pressurizer are integrated into a reactor vessel without any pipe connections between those components. The schematic diagram of the SMART NSSS is shown
