AbstractThe article provides a brief overview of the effect of various separation schemes in horizontal steam generators (PGV) of nuclear power plants on the quality of steam produced in the steam path for supply to the turbine. A further increase in the thermal power of the PGV without a significant increase in the overall dimensions is determined by the «retention» of the separation characteristic of the PGV within the limits specified by the dryness of the steam taken. In this direction the key optimization of horizontal PGV should be considered the rejection of louvered separators in favor of steam-receiving perforated sheets with variable perforation and the development of a new thermal-hydraulic scheme for the two-loop WWER-TOI project.
Keywordssteam generator (SG), steam separation, WWER units, steam humidity, evaporation mirror, gravity separation, submerged perforated sheet (SPS), steam-receiving perforated sheet, technical and economic indicators
