Abstract
In a nuclear-reactor power-generating installation having a main and an auxiliary steam-generating boiler, both arranged to receive heat from the reactor core (for example by circulation of reactor coolant gas), and having a turbogenerator which includes a multistage steam turbine through whose stages the steam from the main boiler passes in sequence, there being a steam reheater unit connected between two of the stages to provide reheating of the steam from the main boiler, the invention provides that the auxiliary boiler is connected to supply to the reheater unit steam which reheats the said steam from the main boiler.
Claims5
A gas-cooled nuclear-reactor power-generating installation having
- A. a nuclear reactor core,
- B. a main stream-generating boiler,
- C. an auxiliary steam-generating boiler, independent of said main boiler and distinct therefrom,
- D. a main coolant-gas circulator arranged to circulate coolant gas through the core and through the main boiler, independently of the auxiliary boiler, whereby to generate steam in the main boiler,
- E. an auxiliary coolant-gas circulator arranged to circulate coolant gas through the core and through the auxiliary boiler, independently of the main boiler, whereby to generate steam in the auxiliary boiler,
- F. a main turbogenerator which includes a steam turbine having a plurality of turbine stages through which steam from the main boiler passes in sequence, and
- G. a steam reheater unit connected between two of the turbine stages to reheat the said steam from the main boiler,
- H. the auxiliary boiler being connected to supply to the reheater unit steam which reheats the said steam from the main boiler.
