Steam generator model validation and advanced feedwater control system design for the Maanshan PWR (pressurized water reactor)
- Westinghouse Electric Corp., Pittsburgh, PA (USA). Nuclear and Advanced Technology Div.
This is the Final Report of Project RP2126-7, a cooperative effort between Taiwan Power Company, EPRI, and Westinghouse which resulted in two major outcomes: the actual validation of the key low power transient response characteristics of a practical dynamic computer model of the vertical natural circulation U-tube steam generators at the Maanshan pressurized water reactor in Taiwan, and the adaptation of the Westinghouse Advanced Digital Feedwater Control System (ADFCS) control algorithms functional design for application at Maanshan. The nonlinear multinode steam generator model is first outlined. A specially designed test program conducted at Maanshan is described. These tests isolate the key dynamic responses of the steam generator to open loop perturbations in boundary conditions at low power. The validation of the model with test data is then described. Results of comparisons between the measured and the measured versus predicted comparisons of the well-known steam generator level shrink/swell phenomenon show good agreement. The technical features and benefits of the Maanshan ADFCS control algorithms functional design are summarized. This improved functional strategy has proven to provide effective feedwater control over the full range of plant operation at operating nuclear station in Europe. 10 refs., 35 figs.
