Glossary of terms of instrumentation and control for nuclear power plants1 ScopeThis standard specifies common terms and definitions related to instrumentation and control (I&C) for nuclear power plants and their power sources. This standard applies to applications for nuclear power plant; other nuclear facilities can be used with reference to it.2 Basic concepts2.1 Operational states A collective name for two types of states, normal operation and anticipated operational occurrences. [HAF 102 (2004)] 2.2 Normal operation The operation of nuclear power plants within specified operating limits and conditions. [HAF 102 (2004)] 2.3 Design basis Information that determines the value, or range of parameters, of a structure, system, component, or device that performs a specific function and is a design boundary. This information can be either limits (derived from generally accepted practices to achieve a functional goal), or some requirements [derived from operational analysis of the assumed events wherein the structures, systems, components shall meet their functional objects and (or) operational experience]. [ANSI/ISA-67.06.01.2002, definition 3.5]3 Instrumentation control systems and device3.1 Instrument control system 3.1.1 Electrical system Integration of electrical device that performs a certain function. [RCCE.2005] 3.1.2 Instrumentation and control system (l&C system) A system based on electrical, electronic, and/or programmable electronic technology, that performs I&C functions as well as service and supervision functions related to the operation of the system itself. 3.1.3 I&C systems important for safety The instrumentation control system whose failure or malfunction may cause the plant personnel or the public to experience excessive radiological exposure to the instrumentation and control systems, as well as those instrumentation control system to prevent unforeseen consequences of anticipated operational occurrences, including safety systems and safety- related instrumentation control systems.4 Computer applications4.1 Computer-based system The I&C system whose functions are mainly dependent on or completely implemented by microprocessors, programmable electronics or computers. [NB/T 20026-2010, definition 3.10] 4.2 Software Programs (ordered instruction sets), data, rules, and all related documents related to the operation of computer-based I&C systems. [NB/T 20054-2011, definition 3.30] 4.4 Application function The function of an I&C system that performs tasks that are related to a controlled process and not related to the functions of the system itself. Note 1.The application function is usually a sub-function of the I&C function. Note 2.Rewrite NB/T 20026-2010, definition 3.1. 4.5 Application software The part of the I&C system software that implements application functions. [NB/T 20026-2010, definition 3.2] 4.6 Operational system software Software running on the target processor during operation, such as software for. input and / or output drivers, services, interrupt management, scheduler, communication driver, application-oriented libraries, online diagnostics, redundancy, degradation management. [NB/T 20054-2011, definition 3.22] 4.9 Software modification A modification to an approved file (or set of files), such modification will result in a change in executable code. Note. In the early stages of software development (for example, faults found in later stages of development) and in the stage where the software has been used, software modification behavior may exist. [NB/T 20054-2011, definition 3.32] 4.10 Pre-developed software (PDS) Existing software available as a commercial or proprietary product for computer-based systems. 4.11 Software failure A system failure due to a design fault in a software component. Note 1.Because the software consists only of the design without wear or physical failure, all software failures are caused by design faults. Because the triggering events that activate software faults occur randomly during system operation, software failure also occurs randomly.5 Man-machine interface5.1 Alarms When the meter's reading exceeds a setting value or exceeds the setting range, an audible or visual signal is triggered on the alarm panel and other displays, to provide field personnel with information about the device or event. [GB/T 4960.6-2008, definition 4.4.23] 5.5 Alarm prioritization Alarm signal processing function or mechanism for alarms classified by importance. Note. Priority can be defined in advance or determined dynamically based on plant operating conditions. [NB/T 20027-2010, definition 3.12] 5.6 Alarm signal processing The logic or mechanism for processing the alarm signal before identifying the alarm and passing it to the alarm display processing unit for display to the operator. 5.7 Alarm signal validation The alarm signal processing function or mechanism, which is used to determine whether the alarm signal correctly expresses the corresponding process or system status.6 Qualification6.1 Device qualification 6.1.1 Baseline parameter The initially determined technical data, which is used as a benchmark for evaluating the acceptable performance of the qualified sample.
