Abstract
The article is devoted to one of the most significant problems in the creation of the international thermonuclear experimental reactor (ITER) - ensuring reliability. In particular, it is important to assess the reliability of elements that belong to various subsystems of the reactor. Using the example of a real subsystem, the influence of various architectural modifications of redundancy schemes on the reliability of the interlock function in the fast energy output system of the ITER thermonuclear reactor is considered. The article analyzes the variants of structures with different levels of redundancy and logical coupling. The simulation was performed using the "k-out-of-n" method (k is the minimum number of elements ensuring the functioning of a system of n elements) with the calculation of reliability. The results obtained make it possible to reasonably choose circuit solutions to increase the fault tolerance of key protective functions.
