The current design of the RF power supply for the International Fusion Materials Irradiation Facility (IFMIF) is based upon tetrodes technology. Due to the improvement in the solid state amplifiers technology, the possibility of using this option for IFMIF is becoming a very competitive alternative presenting a priori several advantages in terms of availability, reliability and logistics. The current technology based on RF tetrodes chains leads no room for substantial improvements in terms of availability being the requirement for the RF system hard to achieve. On the other hand the solid state amplifiers technology opens from its concept several options to increase the system availability. The principal goals of this paper are the use of RAMI (Reliability, Availability, Maintainability and Inspectability) analysis in the RF tetrodes design to led a future work to compare the availability, reliability and logistic performances for both alternatives. The Project will consist in two parts: the development of a logistic support methodology and a specific study of the first part with an example related to the IFMIF facility. First part: Develop a systematic procedure to study the logistic support required by any component of the IFMIF facility, focusing on the component’s effect in the availability of the whole facility Second part: For the radiofrequency (RF) modules in the deuteron accelerator, study its logistic requirements and determinate the optimum quantity of the involved resources. It will comprise a research task of the requirements in the available documentation and a following task consisting in the simulation of the behaviour of the RF modules, in order to determinate the logistic support required.
