Keywords:Decay Heat, Interval Operation, Fast Reactor, Modular Plant

Small modular fast reactor systems are studied that enable the decay heat removal by natural circulation at all station blackout where several reactors are installed by applying the interval operation of several days, reducing the decay heat power significantly relative to that of conventional reactors, which is important for the plant safety.
