Analysis of a turbine trip transient with the Chinshan plant analyzer

To apply fast and accurate simulation techniques to Taiwanese nuclear power plants, plant analyzer technology was transferred to Taiwan from the Brookhaven National Laboratory (BNL) through a cooperative program. The Chinshan plant analyzer was developed based on the BNL boiling water reactor plant analyzer. The simulation speed of the Chinshan plant analyzer is eight times faster than real time. The detail analysis process of the turbine trip transient is demonstrated. The self-initialization procedure automatically generates the desired plant conditions. These plant conditions are saved in a file and read directly for the simulation. The simulation is started by inputting the start time of the turbine trip from the keyboard of a personal computer. The simulation results are shown instantaneously on the screen of a Micro-VAX II workstation. A comparison of the calculated system response with the plant data indicates good agreement. The sequence of events is also close to that of the test result
