Nuclear power plant receives digital upgrades

Areva said it installed a safety-related digital instrumentation and control (I&C) reactor protection system at a U.S. nuclear power plant. Industry sources said the installation took place at Duke Energy’s 2,538 MW Oconee station in South Carolina.

Installation of Areva’s TELEPERM XS enables digital processing of functions for the reactor protection system (RPS) and engineered safeguards protection system (ESPS). The RPS monitors critical operating parameters and initiates an automatic reactor shutdown when conditions are sensed. The ESPS monitors inputs that would indicate the occurrence of process events and initiates engineered safety features, such as containment isolation or emergency core cooling, to ensure plant safety.

In addition to the RPS and ESPS design functions, TELEPERM XS offers reliability improvements with respect to online monitoring and diagnostics capabilities compared to the currently installed analog systems.
