MELTAC® performs all of the nuclear plant safety functions including:


  • Nuclear Instrumentation
  • Reactor Protection
  • Engineered Safeguards Actuation
  • Safety Component Logic
  • Touch Screen Safety Controls
  • Safety Displays


Unique Features


Improved System Utilization


  • Parallel redundant CPU modules do not require manual switching of the subsystems, reduce risk of system failures, and improve system availability.


Hardware and Software Self-Diagnostics


  • Assists in identifying and locating parts and component failures should they occur.


Protection from Common Cause Failures


  • MELTAC® power interface modules are designed to process signals without using software in the event of a software common cause failure.
  • Physical separation and electrical isolation of safety and non-safety divisions achieved using optical data links, as required by IEEE 384.
