Reactor protection system
Product details
When it comes to safety in a nuclear power plant, the Reactor Protection System (RPS) is the most important Instrumentation and Control system.
Underpinned by our patented and world-leading Spinline™ technology, the Rolls-Royce Spinline™ RPS gathers the functionalities of the Reactor Trip system as well as the ESFAS Engineering safety features actuation system. It monitors vital reactor operation parameters and in case of emergency automatically shutdown the reactor and determine the corrective actions to be taken.
All the circuits involved in correcting dangerous situations are activated by the Spinline™ RPS including: emergency shutdown of the reactor core (which interrupts the nuclear fission reaction by dropping rods into the reactor core), safety injection, start-up of the emergency feed water, steam line and feed water line isolation, containment spraying and isolation.
Rolls-Royce Reactor Protection System uses Spinline™ technology.
Features
Because safety is so important in a nuclear environment the Rolls-Royce Reactor Protection System follows the criteria outlined in international standards and recommendations, including:
- Single failure criterion;
- Test during full power operation;
- Protection against common cause failure;
- Continuous monitoring to prevent safety actions from being bypassed and hence prohibited actions from being triggered;
- Keeping the system safe in the event of a failure;
- Execution of all protection actions at the right time;
- Possibility of triggering the emergency shutdown and the safety functions manually from the control room.
