The objective of this thesis is considering the safety analysis of the simplified cooling system of a single module of the ITER Central Solenoid in a cold test facility to classify the different abnormal transients and identify the components failure that may drive the system into a Loss-Of-Flow Accident. The IDPSA framework is applied for the first time to a fusion system to study the dynamic response of the system. Two different operating condition are considered: a first simplified case, in which it is assumed a constant current flowing in the module. In the second part, the real ITER current scenario is considered to study the consequence of the abnormal transients both for the safety of the facility and the consequence for ITER.
