Abstract

Steam turbine for use in nuclear power stations operating at fixed steam pressure on wet steam cycles, designed to operate with the most favourable thermal efficiency on temporary low load, has at least the most important expansion stages provided with two or more flow paths with separated steam inlets, so that on part load, power is generated only on one or some of these flow sections while the remainder receive only cooling steam.
