Full-scope digital instrumentation and controls system (I&C) technique is being introduced in Chinese new constructed Nuclear Power Plant (NPP), which mainly includes three parts: control system, reactor protection system and engineered safety feature actuation system.
However, while I&C system being digitalized, three issues are encountered: (1) software common-cause failure, (2) the interaction failure between operator and digital instrumentation and control system interface, and (3) the non-detectability of software failure.
In digital instrumentation and control systems in NPPs such as a reactor protection system and an engineered safety features actuation system, multiple fault-tolerant techniques are designed to prevent the undesired system behaviors by faults.
The neutronic safety parameters were measured with digital instrumentation & control (I&C) system of the 3 MW TRIGA research reactor.
Digital instrumentation and control (I&C) systems are increasingly used in the nuclear engineering domain.
In this work, 37 safety grade digital instrumentation and control (I&C) systems were analyzed by Failure Mode and Effects Analysis (FMEA), which is suggested by IEEE Standard 7-4.3.2 7-4.3.2 2003
Digital instrumentation and control (I&C) systems can provide important benefits in many safety-critical applications, but they can also introduce potential new failure modes that can affect safety.
With the fairly recent adoption of digital control and instrumentation systems in the nuclear industry a lot of research now focus on the development expert fault identification systems.
Environments in nuclear power plants (NPPs) are changing as the design of instrumentation and control systems for NPPs is rapidly moving toward fully digital instrumentation and control, and modern computer techniques are gradually introduced into main control rooms (MCRs).
In-Car graphics systems are evolving rapidly with an increasing amount of digital instrumentation used inside of automotive designs.
He points to the shift to digital instrumentation as one example.
