Safety systems

Spinline™ technology

Spinline™ is a modular and digital solution dedicated to developing and/or upgrading safety I&C used in nuclear reactors. 
Spinline™ is specifically designed to implement any Class 1E and category A IEC-61226 safety I&C functions, at a level of qualification and certification where conventional Distributed Control System (DCS) or Programmable Logic Controllers (PLC) cannot be used. 
Spinline™ can be used in any Safety system such as reactor Protection System (RPS) and Neutron Instrumentation system (NIS), in new nuclear power plants and for modernisation of existing safety I&C systems in established plant.


  • Safe operation and unproblematic maintenance due to modular, scalable and flexible design
  • Improved availability through self testing and automated periodic testing; 
  • Deterministic behaviour, fail-safe and fault tolerant features, functional diversity, physical and functional separation are the main features of Spinline™ to comply with international nuclear standards;
  • State-of-the-art performance on a long term basis thanks to Rolls-Royce ability to provide long term support for plant life.
