摘要：
A combined experimental and computational method (SCRM) of taking into account spatial effects and its application for determining the reactivity of VVER-440, -1000, and -1200 power units are described. It is shown that with the help of this method it is possible to take account of spatial effects and thereby eliminate a systematic discrepancy between the computed and measured performance of the control rods. The accuracy of the method is determined based on the combined calculated and measured efficiency by using numerical statistical modeling of tests design to determine the efficacy of the emergency protection at different types of reactor installations with VVER.
