CONSTITUTION: A safety injection tank(100) includes a body unit(110) and a high flow output unit(120). The body unit stores the emergency core coolant. The high flow output unit is arranged in the body unit. A cover is arranged on one side of the high flow outlet of the high flow output unit. The cover reduces the pressure of the emergency core coolant and is bended to prevent the emergency core coolant from being inputted to the upper side and the lateral side. A low flow output unit(130) is arranged on one side of the high flow outlet.
