description: The subject of the graduate qualification work is "Uncertainty analysis of the simulation results of SG PHRS operation in the Korsar/GP code".The work is devoted to the uncertainty analysis of the Korsar simulation results of the passive heat removal system from the core of a nuclear reactor through steam generators (SG PHRS) operation. The practical value of the work, which was performed as a result of undergraduate practice at the scientific and design department of JSC âAtomenergoproekt, is in obtaining calculated data that can be used for validation, verification and cross-verification of the KORSAR code.The work provides an overview of the passive heat removal system from the core of a nuclear reactor through steam generators and residual heat release in the core of a nuclear reactor, described the simulation process of the experiments of JSC "NPO CKTI" for SG PHRS in Korsar code, separately, as well as using the mathematical modeler SimInTech, built nodalization schemes for the emergency cooldown heat exchanger, steam-condensate pipeline and emergency heat removal tank, visualized the design scheme, outlined the methodology for estimating the uncertainty of calculated thermal-hydraulic codes, evaluated the uncertainties of validation code and constructed tubes of uncertainty for the output parameters. By covering the calculation results, the uncertainty tubes confirm the success of the performed analysis.
