CALCULATION OF AVAILABILITY TARGETS FOR ITER DIAGNOSTICS
Abstract
The article is devoted to the problem of setting availabilities for diagnostic systems (diagnostics) in the ITER (International Thermonuclear Experimental Reactor) project. Such systems should provide the required level of availability with which numerous parameters of the ITER are measured. A number of difficulties arise on the way of problem formulation and its solution. These include, in particular, the uniqueness of the object, the variety and multiplicity of parameters and diagnostics, the complex interrelation between them, and the absence of analogues in the reliability literature. The paper presents the results of modeling using the developed earlier mathematical model and the computational algorithm. Also, by the example of a simplified model of the ITER diagnostic complex, the sensitivity to the values of empirically set coefficients is analyzed. The obtained results can be used by the developers of various diagnostic subsystems of ITER in the form of defined requirements.
