Looking for information on nuclear control systems

Click For Summary
SUMMARY

This discussion centers on the implementation of advanced control systems in nuclear reactors, specifically focusing on alternatives to PID controllers. The participant, a MaSc student in electrical engineering, seeks resources for understanding control systems in nuclear plants, particularly regarding modeling and simulation. Key insights include the use of digital instrumentation and control in modern plants, with specific mention of setpoints for core power, temperature, and primary system pressure that activate control rod drive systems in Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs).

PREREQUISITES
  • Understanding of control systems, particularly alternatives to PID controllers
  • Familiarity with nuclear reactor operations, specifically PWR and BWR mechanisms
  • Knowledge of digital instrumentation and control technologies
  • Experience with modeling and simulation techniques in engineering
NEXT STEPS
  • Research the Digital Control Document (DCD) resources available at the Nuclear Regulatory Commission (NRC)
  • Explore advanced control strategies for nuclear reactors beyond PID controllers
  • Study the specifics of control rod drive systems in PWRs and BWRs
  • Investigate modeling and simulation software used in nuclear engineering
USEFUL FOR

Electrical engineering students, nuclear engineering professionals, and researchers interested in advanced control systems and their applications in nuclear reactor technology.

I am a MaSc student in electrical engineering. In my undergraduate degree I focused on controls and now want to do a thesis on implementing controls other than PID in reactors. I am looking for a good source of information on controls systems in nuclear plants and the modelling and simulation of plants. Any info will be much appreciated

Most details are proprietary.

Perhaps one can peruse the DCDs at the NRC. Most modern plants use digitial instrumentation and control. There are numerous setpoints on core power/power distribution, temperature, primary system pressure, etc, which if a threshold is exceeded will trigger the control rod drive systems. In PWRs, the magnetic suspension systems are de-energized, and the control rods drop into the core. In BWRs, the control rods/blades are inserted hydraulicly from beneath the core.
