摘要

Availability analysis for Chinese fusion engineering testing reactor (CFETR) is very important at the pre-conceptual phase. Availability apportion are the theoretical basis of system design of CFETR. Availability analysis informs the development of the CFETR overall system and subsystem design. Availability analysis will enable the identification of key subsystems to achieve availability targets. The duty cycle of CFETR should be at least 0.3-0.5. Such design goals require all subsystems of CFETR must have a pretty high availability. The availability of CFETR can be defined by break time analysis results. Analysis results proved that the availability of CFETR is 0.5-0.7. All availability subsystems of CFETR can be apportioned from their relevant mean time before failure (MTBF) and mean time to repair (MTTR) data to meet the availability goals. The relation between reliability, maintainability and availability indicates that a subsystem could have a high availability though its reliability is pretty low. Availability apportionment and analysis indicate that the availability of blanket and divertor should be 0.769-0.91 to meet the design requirements and their availability can be improved by increase the MTBF and reduce the MTTR of blanket and divertor with the development of remote handling or remote maintenance technology for fusion reactor.
