description: Topic of the final qualification work: Â«Justification for the introduction of a correction factor for experiments to determine the differential efficiency of the conÂ­trol elements of the CPS VVER-1000Â». This work is devoted to the determination of the differential efficiency of CPS regulators. A comparison was made of the results of a physical experiment conducted at the first power unit of the Rostov NPP with a VVER-1000 reactor at the first load, and computational modeling using software. The tenth group of control elements of the CPS, which is used in the regulation of the reactor, was considered. The software package SAPFIR_95&amp;RC_VVER was used for computational modeling.In the course of the work, a model of the active zone of the VVER-1000 reacÂ­tor was developed, which corresponds to the first load of the first power unit of the Rostov NPP. Both stationary and kinetic calculations were performed with the help of software. The gradual introduction of the 10th group of CPS OR into the core was modeled.The necessity of adjusting the experimental data to determine the differential efficiency of CPS OR was substantiated. Two types of corrections were introduced, which led to the agreement between the calculated and experimental values.
