Data on deformations of protective reactor compartments of units 3 and 4 of Rivne NPP are obtained. According to the results of observations of 2019-2020, significant compression of the seal, which could significantly affect the operational reliability of the equipment on the 3rd and 4th units was not observed. Executive diagrams of the planned-height position of the crane tracks for all objects Rivne NPP facilities, where the works were performed, were drawn up. On the 1st and 2nd units a sharp deterioration of the running properties of the crane 30/5 t.s. explained not by the processes of subsidence of columns, which would require additional work to strengthen the foundations, but only work on the installation and repair of the building structures, which could lead to changes in the position of crane girders, or even the rolls of the columns. Attention should be paid to the significant excess of the allowable values of the planned position of the crane track of the turbine compartment of units №1 and 2, namely the narrowing-expansion of the crane base, which reaches 58 mm.
