The present invention provides a PWR or CANDU nuclear power plant having a primary circuit and a secondary circuit. In addition to a group of main steam boilers, the nuclear power plant has a lower pressure steam generator (LPSG) connected to primary circuit downstream of main boilers and providing additional cooling to reactor coolant. The lower pressure steam generated by LPSG is used by internal consumers of lower pressure steam. Those consumers include any combination of the following: feed water heaters, steam reheater of the moisture separator and reheater (MSR), the connection to the main steam turbine used to supply additional steam flow to the turbine, a steam turbine driven feed water pump, a steam turbine driven condenser cooling water pump, and a steam turbine driven reactor coolant pump. It allows to use excessive thermal capacity of the reactor without major modifications to the secondary side of the plant (main boilers, feed water heaters, steam turbine, feedwater pumps, MSR, piping, etc.). The invention can be used for power uprates of existing nuclear power plants, as an alternative for main boiler replacement (due to aging main boilers), or for new construction. Net electrical output can be increased in the range of 6 to 12% depending on selected modification.
