    초록 In HANARO, a multi-purpose research reactor of 30 MWth, the primary cooling system is composed of two heat exchangers, two pumps, piping including valves and instruments for cooling a nuclear fission heat during a normal operation. The flywheel attached to each pump motor shaft provides inertia forces to ensure a slow decrease in coolant flow in order to prevent fuel damage as a result of a loss of power to the pump motor. During operation at normal speed, the flywheel has sufficient kinetic energy to produce high-energy missiles and excessive vibration of the reactor coolant pump
    assembly if the flywheel should fail. Overspeed of the pump rotor assembly during a transient increases both the potential energy for failure and the kinetic energy of the flywheel. The safety consequences could be significant because of possible damage to the primary cooling system, the containment, or other equipment or systems important to safety. This paper describes the structural integrity of the flywheel including the test requirements, test methods and results. It was confirmed through the test results that the structural integrity of each flywheel is maintained in safety.
