Abstract
Questions of reliability and availability play an increasing role in fusion technology. Considering the large amount of technical efforts and capital spent, the risk of undesirable developments arising from inappropriate design must be kept as low as possible. The existing data base is extremely small to yield fully conclusive results already now. But in many cases acceptable solutions of technical problems with regard to reliability are achievable, if design precautions compensate for the uncertainty in data. This principle will be demonstrated in two examples: a neutral beam injection power supply control system and a power supply control system for superconducting magnets. The method used for reliability analysis is based on the Boolean algebra with restricted variables [1], which allows to identify weak and critical points in the design especially by representing results in block diagrams. The method has the additional advantage that not only the influence of the reliability of single components but also of complete subsystems on the overall result can be evaluated easily. By varying the input data or altering the design supplementing parametric studies can be performed. This is very important for investigating design alternatives, and, therefore, already now the method is a support in systems reliability analyses of fusion plants components and subsystems.
