Theme of the masterâs work: «Availability analysis of the industrial cooling circuit of responsible consumers of ventilation systems». This work is devoted to the availability analysis of the industrial cooling circuit of responsible consumers of ventilation systems. The following stages of work can be distinguished: Qualitative analysis of system availability;Analysis of the source data; Development of a system failure tree and determination of introductory parameters of basic events; Calculation unavailability rate of system; Analysis of uncertainties, significance and sensitivity. The work was carried out on the basis of the IAEA data on the reliability of components for use in a probabilistic safety assessment using a logical-probabilistic model. An analysis of the uncertainty of the inaccessibility coefficient was carried out. It is based on computer code that generates a distribution of values in a given range using the Monte Carlo method. The final part of the work is the analysis of significance and sensitivity. Conclusions are drawn about the contribution of the system elements to its readiness and reliability. |
