The document discusses the instructor workstation (IWS) used for training operating personnel at the Rooppur NPP Training Center. The IWS allows instructors to control and monitor the full scope simulator, create abnormal situations, record training sessions, and view monitored parameters. Key features of the IWS include the ability to input commands, reset the simulator to initial conditions, freeze or backtrack the simulation, and store snapshots. The IWS has 200 initial conditions and supports password protection. The IWS is used for applications like startup and shutdown training as well as accident analysis scenarios involving events like a steam line break or condenser vacuum break. In conclusion, the IWS is an efficient tool to help instructors conduct training smoothly.
