A

A user interface to control and monitor simulation.

15
Q

Limits of Simulation

A

Points at which events on the simulator may progress beyond the reference unit design limits where simulation could possibly be inaccurate and create a potential for negative training.

16
Q

Malfunction

A

A simulator feature or capability that provides for instructor-controlled degradation of performance of simulated plant components, equipment, or systems.
Override capability is not considered a malfunction.

17
Q

Modification

A

Any change in the simulation software or hardware

18
Q

Negative Training

A

Training on a simulator whose configuration or performance leads the operator to an incorrect response to or understanding of the reference unit.

19
Q

Noticeable Difference

A

Any difference in the physical attributes or dynamic response between the simulator and the reference unit that can be distinguished by an observer and confirmed by a Subject Matter Expert.

20
Q

Operating Procedures

A

Controlled copies of procedures, including normal, abnormal, off normal, emergency, surveillance, and alarm response procedures of the reference
unit.

21
Q

Operator

A

A licensed operator, or senior licensed operator, or a person in training to be a licensed operator or senior licensed operator.

22
Q

Overrides

A

To interrupt or modify the input/output (I/O) data transfer between the simulator mathematical models and the panel instrumentation.

23
Q

Passive Failure

A

A failure of a component or system that does not become evident until the affected component or system is called upon to function.

24
Q

Performance Testing

A

Testing conducted to verify a simulator’s performance as compared to actual or predicted reference unit performance.

25
Q

Physical Fidelity

A

The degree of similarity between the simulator and the reference unit, such as physical location of panels, equipment, instruments, controls, labels, and
related form and function.

26
Q

Post Event Simulator Testing

A

Reconstruction of a plant event on the simulator to
ensure that the simulator is capable of reproducing the response of relevant reference unit parameters within the scope of simulation.

27
Q

Real Time

A

Simulation of dynamic performance in the same time base relationships, sequences, duration, rates, and accelerations as the dynamic performance of the
reference unit.

28
Q

Reference Unit

A

The specific nuclear power plant unit, identified by a unique docket number, from which the simulator control room configuration, system control arrangement, and simulator design database are derived.

29
Q

Remote Function

A

A set of simulator features implemented in the math models, which enable the instructor to control a designated set of external conditions which are not
installed in the control room but whose status affects plant response such that it is perceivable in the control room.

Examples of remote functions include environmental
parameters, manually operated equipment, equipment operated by local controls, and lifted leads or jumpers.

30
Q

Reset

A

The Instructor Station control function used to initialize plant conditions and instructor initiated actions to a previously saved initial condition.

31
Q

Repeatability

A

The capability of the simulator to have successive tests of its dynamic performance conducted in the same time base relationships, sequences, duration, rates, and accelerations which, in turn, produce the same results within the limits required by this procedure.

32
Q

Run

A

The controlled resumption of simulation.

33

Scenario

A

Any set of simulator operations performed in accordance with a lesson plan or guide for the purpose of familiarization, training, or examination of operators.

34
Q

Scenario Based Testing (SBT)

A

Simulator testing that verifies that the simulator is
capable of being used to satisfy predetermined learning or examination objectives without exceptions, significant performance discrepancies, or deviation from the approved scenario sequence.

35
Q

SBT package

A

The collection of an approved scenario guide, appropriate marked-up procedures, collected data from a defined monitored parameters file, an alarm summary and a scenario based testing checklist that serves as proof of a completed SBT.
