Study on Thermal Performance Diagnosis and Analysis of Million Kilowatt Pressurized Water Reactor Units
The pressurized water reactor (PWR)power plant will conduct performance assessment tests before the formal commercial operation of the unit to verify whether the output of the steam turbine generator unit reaches the guaranteed value.The thermal performance diagnosis and analysis work of the unit can timely detect and handle potential defects,and unleash the potential for power elevation.This paper mainly reports the progress of thermal performance diagnosis and a-nalysis of the secondary circuit of a M310 PWR steam turbine generator unit in an actual plant during full power opera-tion,trying to provide useful information for further establishment of a standardized thermal performance supervision sys-tem in the future.
