First developed and deployed in 1985, NUMAC is a digital plant control system created to replace legacy analog neutron monitors. These monitors capture plant data to improve plant performance and increase plant longevity. Over the decades, the system has evolved to align with current computing power specifications.
Proven NUMAC electronics and simplified chassis installation
Automated and continuous self-check
Simplified calibration via menu-driven directions
Standard NUMAC help menus, parameters, and status screens
Redundant internal power supplies
Common spares with other NUMAC systems
Data transfer to the plant process computer (PPC)
Observes operation reactor power levels from 20% to 125% capacity during normal operation and transmits reactor trip signals to the plant safety systems.
Intended to replace the entire source range monitor (SRM) and intermediate range monitor (IRM) system, the WRNM tracks reactor power from 0% to 20% capacity and transmits trip logic at startup power levels.
Compares readings to values from the PRNM system to calibrate the in-core power sensors. It controls a drive mechanism and indexer that governs a sensor next to each LPRM sensor.
Rod Control System – Reactor operators can insert or withdraw control rods via the rod control system for power generation purposes and to monitor rod status.
