* Definition of Nonconformance:
A nonconformance is a state or an action (judgment) deviating from the normal 
state or action (judgment). In a power plant, nonconformances include a wide 
range of events from troubles with legal reporting obligations to minor breakdown 
of instrumentation and lighting troubles found during normal plant inspections. 

*Note that nonconformance control grades differ from seismic design classes.
