Theme of the final qualifying work: "Analysis of the readiness of the industrial cooling circuit of responsible high-pressure consumers". This work is devoted to the analysis of the readiness of the industrial cooling circuit of responsible high-pressure consumers. The work consists of the following stages: 1. Qualitative analysis of system availability; 2. Development of the system event tree and determination of the parameters of the basic events; 3. Calculation of system unavailability indicators; 4. Uncertainty analysis of the unavailability coefficient; 5. Significance and sensitivity analysis. The IAEA report on the reliability of components for use in a probabilistic safety assessment became the database for the work. The calculation model is based on a logical-probabilistic model with the use of special programs for constructing failure trees and calculating system unavailability indicators. According to the Monte Carlo method, an analysis of the uncertainties of the unavailability coefficient was carried out on the basis of a computer program. The result of the work is an analysis of the significance and sensitivity, according to which conclusions are drawn about the contribution of system elements to its readiness and reliability. |
