Scope

Main technical content: This standard aims to study the scope and management of unit testing for system equipment in nuclear power plants, and clarify the requirements for both the unified scope of unit testing and the management of unit testing. According to the type of equipment, this standard divides unit equipment into mechanical equipment, electrical equipment, and instrumentation control equipment. Among them, mechanical equipment is divided into rotating equipment (including motors, pumps, fans, etc.) and static equipment (including valves, containers, etc.) according to the mode of operation; electrical equipment is divided into power generation and transformation (diesel generators), power transmission and transformation, plant distribution (including DC), and relay protection according to its function; instrumentation control equipment is divided into general instruments, special instruments (nuclear measurement, radiation, chemistry, etc.), control cabinets, and other instrumentation control equipment (physical security, communication, fire alarm, etc.) according to its application scope. All the testing contents specified in this standard are broad testing scopes. If some equipment lacks certain components or functions, or if there are no conditions or special requirements from the manufacturer, the relevant test contents can be adjusted accordingly. For example, for some valve equipment, the requirement for adjusting limit switches applies. If there are no limit switches, no testing is required. Special equipment not included in this standard, such as cranes and elevators, should undergo unit testing in accordance with the corresponding national standards.
