Description

Boiling Water Reactor Nuclear Plant Simulator _v4.4.5

The purpose of the 1300 MW(e) boiling water reactor NPP simulator is educational — to provide a teaching tool for university professors and engineers involved in teaching topics in nuclear energy. As well, nuclear engineers, scientists and teachers in the nuclear industry may find this simulator useful in broadening their understanding of BWR NPP dynamics and transients and power plant dynamics. As such, the BWR simulator is used at the IAEA Workshop: NPP Simulators for Education.



The simulator can be executed on a personal computer (PC), to operate in real time, and to have a dynamic response with sufficient fidelity to provide BWR plant responses during normal operations and accident situations. It also has a user-machine interface that mimics the actual control panel instrumentation, including the plant display system, and more importantly, allows user’s interactions with the simulator during the operation of the simulated BWR plant.



The current simulator configuration of the simulator is able to respond to the operating conditions normally encountered in power plant operations, as well as to many numerous malfunctions, as summarized in the following table.

##Major control loops.





BWR Plant Overview





BWR Reactivity & Setpoints







The interaction between the user and the simulator is via a combination of monitor displays, mouse and keyboard. Parameter monitoring and plant operator controls, implemented via the plant display system at the generating station ,are represented in a virtually identical manner on the simulator. Control panel instruments and control devices, such as push-buttons and hand-switches, are shown as stylized pictures, and are operated via special pop-up menus and dialog boxes in response to user inputs.
