Nuclear power plant safety system is necessary such that an accident ocurred at Three Mile Island 2 in 1979 can be avoided. Decay heat removal is one of the important aspects in nuclear power plant safety .Decay heat is the removal of the radiation energy emitted by removing the decay heat from the nuclear reactor to the atmosphere which acts as an ultimate heat sink. Decay Heat Removal System (DHRS) relies on passive working mechanism, which applied not only to simplify configuration and work mechanism, but also to increase the performance of the safety system. DHRS can be applied to the current or the advanced generation of nuclear power plants. The current DHRS design frequently act as a part of Emergency Core Cooling System for low pressure level (approximately 28 atm. Setpoint). Air is used to remove the sensible heat from the steel reactor vessel to the atmosphere and it functions as coolant because of its high availability and mobility , which can passively moved by pressure difference. Air cooling system application for DHRS is relatively new, therefore research and development to understand the basic characteristic of the system should be
