Abstract The reheating part of the moisture separator-reheater (MSR) nuclear power plant (NPP) steam turbine occupies a significant MSR volume and requires large consumption metal. superheating low pressure provides by high condensation. This supplies partly from inlet stage bleeding because two superheater stages. significantly less heat transfer intensity at single-phase side reheater comparatively with condensation intensification heated-steam. For such goal different methods can be used:...
