This paper presents a three-tier, critical section selection methodology that is used to identify critical sections for the U.S. EPR™ Standard Nuclear Power Plant (NPP). The critical section selection methodology includes three complementary approaches: qualitative, quantitative, and supplementary. These three approaches are applied to Seismic Category I structures in a complementary fashion to identify the most critical portions of the building whose structural integrity needs to be maintained for postulated design basis events and conditions. Once the design of critical sections for a particular Seismic Category I structure is complete, the design for that structure is essentially complete for safety evaluation purposes. Critical sections, taken as a whole, are analytically representative of an “essentially complete” U.S. EPR™ design; their structural design adequacy provides reasonable assurance of overall U.S. EPR™ structural design adequacy.

The reactor coolant pump in nuclear power plant is the only revolving equipment in the nuclear power plant. Its functional stability will directly affect the security of nuclear power plant. The coolant pump of a very nuclear plant is examined by using response spectrum analysis to analysis dynamic characteristics and responses aiming at finding the natural frequencies of vibration, modes of vibration and seismic responses, and any possible step which may cause damage of the whole system. The favorable spectrum and unfavorable one are investigated as well. The paper focuses on avoiding the detrimental effects caused by earthquakes, therefore may lay down a theoretical foundation for structural design and installation.

Turbo Generator

A space numerical model about 1000MW turbo generator foundation of a power plant is established by ANSYS software, meanwhile analyzing the model’s vibration characteristics and response under the turbo generator working conditions. According to the existing norms, optimizing the foundation based on the linear displacement amplitude control, furthermore researching the corresponding dynamic on the optimized foundation for guidance to structural design.

Operation Results

The recirculating cooling water treatment process of low carbon & environmental protection adopts advanced design concepts of passive and energy saving and emission reduction. This process will be used widely in fossil-fueled power plant, which uses municipal reclaimed water or coal mine drainage. The operation results show that the effluent quality is stable, the concentration ratio is higher and the recirculating cooling water quality is better than the design criteria. It meets the safety and economic operation of units.
