Taking the steam generator of a certain CPR1000 unit as the research object,the thermal hydraulic analysis program of the steam generator is used.Based on the historical operating data of the unit,the thermal performance of the current steam generator is analyzed and evaluated by comparing indicators such as thermal power,steam pressure,aver-age temperature on the primary side,fouling thermal resistance,and tube blockage rate,providing suggestions for the op-eration and maintenance of the steam generator.The performance evaluation results indicate that the steam generator of the CPR1000 unit is currently running well and can meet the design requirements.However,the equivalent fouling ther-mal resistance of the steam generator is slightly higher than the design value.Therefore,it is necessary to closely monitor the changes in the thermal parameters of the steam generator and regularly analyze the trend of the equivalent fouling thermal resistance over time.
