7300 PROCESS INSTRUMENTATION SCALING. I&C Training Programs

The course presents methods to calculate different loop component setpoints in order to obtain the desired operations from a process loop.

The course reviews the equations and mathematics associated with calculations for various components such as bistables, square root extractors, function generators, and multiplier/dividers. 

The concepts associated with obtaining and measuring lead and lag time constants are also studied. The data used for problems and calculations originates from the Precautions, Limitations and Setpoints document and emphasizes plant systems such as the overtemperature DT and rod control circuits.

Course Schedule:

• Day 1: Scaling overview:  definition of scaling; plant references; principles and examples; dynamic compensation; controller principles.
• Day 2: Scaling on circuit cards:  summing amplifiers, mixing amplifiers; lead/lag amplifiers.
• Day 3: Scaling on circuit cards (continued); function generators; multiplier/dividers; signal comparators; controllers.
• Day 4: System scaling:  definitions and method, overtemperature DT rod control; pressurizer pressure; feedwater control.
• Day 5: Review and examination; systems tests; review; written examination.
