Scenario-based training is a key process in the use of Full Scope Simulators (FSS) for operator training. Scenario-based training can be defined as any set of simulated plant operations performed with a specific training objective in mind. In order to meet this training objective, the ANSI/ANS-3.5-2009 [1] standard requires that certain simulator training scenarios be tested to ensure that they reproduce the expected plant  responses, that all plant procedures can be followed, and that scenario-based training objectives can be met. While malfunction testing provided a narrow view of the simulator performance revolving around the malfunction itself, scenario testing provides a broader, overall view. The concept of instructor validation of simulator scenarios to be used for training and evaluation, and oversight of simulator performance during the validation process, work hand-in-hand [2]. This is where Scenario-Based Testing comes into play. With the description of Scenario-Based Testing (SBT) within Nuclear Energy Institute’s NEI 09-09 white paper [2] and within the ANSI/ANS-3.5-2009 standard, the industry now has a way forward that reduces the regulatory uncertainty. 
Together, scenario-based testing and scenario-based training combine to produce better simulators which in turn can be used to more effectively and efficiently train new and existing power  plant operators. However, they also impose a significant data gathering and analysis burden on FSS users. L-3 MAPPS’ Orchid® Instructor Station (Orchid® IS) facilitates this data gathering and analysis by providing features that automate this process with  a simple, centralized, easy to use interface.
