Safety analysis of water cooled components inside the JET thermonuclear fusion tokamak
The transient thermal behaviour of a number of components, installed in the vessel of the world's largest fusion tokamak (JET) has been examined with a theoretical model, which simulated normal operational conditions and abnormal scenarios namely: loss of coolant flow; loss of torus vacuum; and combinations. A number of theoretical results related to water and cryogenically cooled devices have been validated by a comprehensive experimental campaign conducted both inside the JET plasma chamber and in a test rig. The performance of water cooled components which may be subjected to boiling or freeze-up risks in case of a loss of water flow event has also been analysed. A completely automatic safety protection system has been designed on the basis of these analyses and implemented in the routine JET operation.
