摘要：

The power coefficient of reactivity of VVR-Ts was previously determined only in the range 10-11 MW. The aim of the present work was to determine the power coefficient of reactivity in the range 1-10 MW. The experiment was performed on a completely depoisoned reactor. The change in the reactivity excess was determined according to the position of the control rods. It was shown experimentally that the power coefficient of reactivity is not constant and is negative for the given power range. Thus, the VVR-Ts reactor can operate safely in different operating regimes.
