Abstract
A saturated steam or weakly superheated steam thermodynamic cycle in an electricity generating plant includes at least a nuclear energy source and a turbine having at least a high-pressure module, a medium-pressure module and a low-pressure module. The steam flows successively through the high-pressure, medium-pressure and low-pressure modules. The steam undergoes a first drying and/or superheating cycle between the high-pressure and medium-pressure modules and also a second cycle comprising at least a drying and/or a superheating process between the medium-pressure module and the low-pressure module.

A saturated steam or weakly superheated steam thermodynamic cycle, in an electricity generating plant, comprising:
- at least a nuclear energy source, and
- a turbine including:
- at least a high-pressure module,
- a medium-pressure module, and
- a low-pressure module,
- wherein the steam flows successively through the high-pressure, medium-pressure and the low-pressure modules, the steam undergoes a first drying and/or superheating cycle between the high-pressure and medium-pressure modules, and the steam undergoes a second cycle that includes at least one drying process between the medium-pressure module and the low-pressure module, and
- wherein the superheating in the first drying and/or superheating cycle is provided by using steam taken from a first steam bleed point of the high-pressure module and the superheating in the second cycle is provided by using steam taken from a second steam bleed point of the high-pressure module.
An electricity generating plant comprising:
- at least a nuclear energy source, and
- a turbine including:
- at least a high-pressure module,
- a medium-pressure module, and
- a low-pressure module, wherein the modules are interconnected by a steam circuit adapted to make the steam flow successively through the high-pressure, medium-pressure and low-pressure modules;
- at least a dryer and a superheater located between the high-pressure and medium-pressure modules;
- and
- at least one second dryer and a second superheater locate between the medium-pressure and the low-pressure modules,
- wherein the superheater is provided with steam taken from a first steam bleed point of the high-pressure module and the second superheater is provided with steam taken from a second steam bleed point of the high-pressure module.
