Purpose of modernization
- as a result of the overhaul of pipelines according to the developed project, further deformation processes of pipelines should be excluded and the ring stiffness and spatial strength of pipelines should be restored, as at the moment there is corrosion of the metal of pipelines from the inside and outside;
- development of measures for the overhaul of 4 lines of pressure circulation conduits along a length of 20÷30 m from the flanges of the BNS-1 circulation pumps and sections of the circulation conduits of Power unit 1 subject to apparent deformations;
