This document divides the life cycle of a nuclear power plant into the following 5 major stages and 14 minor stages:

a) Design: 1) Concept design (including site selection); 2) Definition and application conditions of nuclear power plants; 3) Risk analysis; 4) Determination of nuclear power plant demand; 5) Nuclear power plant demand allocation; 6) Detailed design:

b) Construction: 1) Manufacturing; 2) Construction and installation:

c) Debugging: 1) Nuclear power plant confirmation; 2) Acceptance inspection of nuclear power plants:

d) Operation and supervision management: 1) Operation and maintenance; 2) Performance tracking; 3) Transformation:

e) Decommissioning: Decommissioning and final disposal: Based on the above stage division, this document provides the reliability, availability, maintainability and safety tasks of each stage of the nuclear power plant life cycle: Objectives, requirements, inputs, results and verification tasks provide guidance for the systematic management of the entire process of nuclear power plants, but also emphasize the operation of nuclear power plants: Based on the applicability of the contents of this document to specific nuclear power plants and taking into account the special needs of specific nuclear power plants, the unit shall evaluate how to apply it to specific In addition, the requirements of this document only involve reliability, availability, maintainability and safety, which need to be applicable in accordance with GB/T 19001: The required quality management system is implemented with the support of the required quality management system: Nuclear power plant reliability, availability, maintainability and Security Management Specifications

1 Scope

GB/T 44080-2024 is the Chinese management specification for reliability, availability, maintainability and safety in nuclear power plants. RAMS management is familiar from the railway sector, where EN 50126 established the approach; this document brings the same life cycle discipline to nuclear plant, where the four properties interact in ways that make treating them separately unsafe, since a maintainability decision taken in detailed design determines the outage time that determines the availability, and the risk analysis that justified the design has to be carried forward and revalidated at every later stage or it becomes a historical document. The standard sets the general RAMS requirements, the life cycle based management framework, and then the management specification for each stage of the life cycle in seventeen pages, giving for every stage the objectives, requirements, inputs, deliverables and verification tasks. Six informative annexes provide an example RAMS specification, a RAMS programme, examples of plant parameters, the RAMS tasks mapped onto each life cycle stage, the risk analysis and evaluation methods and examples of risk acceptance criteria. It applies to RAMS management at every stage of the nuclear power plant life cycle, from siting through decommissioning, and is written to sit within a quality management system meeting GB/T 19001.

This document specifies the implementation of a coherent whole process management of reliability, availability, maintainability and safety throughout the life cycle of a nuclear power plant: Methods and requirements: This document is applicable to RAMS management at all stages of the life cycle of nuclear power plants:
