Method for temperature measurement confidence control in the process of WWER reactor operation

Method for computation of the temperature measurement confidence limit of WWER reactor coolant at reactor inlet and outlet and fuel assembly inlet is suggested. The temperature calculated value at reactor outlet is determined as a function of saturation pressure in steam generators. Computation data are compared to the service data for WWER-440 reactor. The suggested method makes it possible to automize the data processing and to increase accuracy of measured and calculated values determination. Increase of the temperature control accuracy and reliability permits to use nuclear reactor and NPP reserve power. Automatic data processing permits to determine energy release fields in a nuclear reactor that increases the accuracy of determining nuclear fuel burn-up, time of fuel cycle
