Instrumentation & Control

The control center of a nuclear power plant

The Instrumentation & Control Business Unit Engineer, manufacture and deliver instrumentation and control (I&C) solutions for nuclear power plants worldwide.

It provides customers with a full range of expertise in all activities connected to instrumentation and control systems for nuclear power plants to offer solutions that meet all their safety and reliability requirements.

The Instrumentation & Control Business Unit’s portfolio is organized around four main product lines:

  • Safety automation
  • Nuclear instrumentation
  • Stand-alone systems
  • Lifecycle solutions

Supported by cyber security, human factors engineering, simulators, I&C systems engineering.

Safety Automation

The Instrumentation & Control is the central nervous systems of the power plant.

More than 80 safety I&C systems installed in 45 reactors in 17 countries across the world and more than 100 nuclear instrumentation systems in operation worldwide.


To guarantee the safety of its customers’ facilities, the Instrumentation & Control Business Unit offers two state-of-the-art solutions:

  • TELEPERM XS digital platform
  • Non-computerized analog solutions


The TELEPERM XS digital platform is the global market leader, controlling all of the plant’s safety systems (hardware and software components for the engineering, installation and operational phases). It is suitable both for new facilities and for modernizing existing plants.
Framatome teams also replace outdated analog technologies by installing digital platforms.

Nuclear instrumentation

Nuclear instrumentation systems measure and control the physical parameters of the reactor core.

The Instrumentation & Control Business Unit designs and manufactures measurement equipment to control and protect the reactor, such as instrumentation to measure:

  • in-core neutron flux
  • ex-core neutron flux
  • water level of the reactor vessel
  • position of the reactor control rods
  • boron concentration of the primary coolant

Stand-alone systems

Framatome offers instrumentation and control system solutions that meet the strict nuclear requirements for the stand-alone systems installed on nuclear power plants, such as automation solutions for refueling machines, cranes, control rod drive mechanisms, fuel inspection and service systems, manipulators, test systems for pressurizer safety valves.

Simulation equipment

To meet the demands of safety authorities and customers, the Instrumentation & Control Business Unit designs full-scale nuclear power plant simulators and engineering simulators through its subsidiary CORYS.

  • Full-scale simulators, combined with a life-size replica of the control room, provide training for plant operators in all reactor situations.
  • Engineering simulators provide essential support for design teams.

CORYS: a leading expert in nuclear simulation

A subsidiary jointly owned by Framatome (50% stake), EDF (25% stake) and IFP Training (25% stake), CORYS has developed a complete simulation environment for creating simulation solutions to support the design stages of a reactor, up to the completion of a full-scale simulator for training nuclear power plant operators.
