Dynamical Error in Measuring VVÉR Coolant Temperature

  • Published:
Atomic Energy Aims and scope

Abstract

A computational-experimental method for predicting and estimating the dynamical error in measuring the coolant temperature in VVÉR transient regimes is examined. The method is based on thermal probing of a thermocouple by passing an electric current pulse through the thermocouple wires and detecting and analyzing the transient characteristic using a special algorithm. The special features of the transient characteristics are investigated and an example of estimating the error is presented.
