With the continuous development of nuclear energy technology, high temperature reactors are becoming increasingly widely used. Compared with traditional nuclear reactors, high temperature reactors have higher thermal efficiency, stronger safety and a wider range of applications. However, the special working conditions of high-temperature reactors also put forward higher requirements for the construction of nuclear facility components.
ASME BPV III Division 5 Overview
Scope of application: Covers the construction of vessels, pipes, pumps, valves, supports, core support structures and non-metallic core components used in high-temperature reactor systems and their supporting systems.
Materials: Specifies the performance requirements, test methods and inspection standards for metallic and non-metallic materials used in high-temperature reactor nuclear facility components.
Design: Provides design guidelines for high temperature reactor nuclear facility components, including high temperature design methods, stress analysis, creep fatigue assessment, etc.
Extended life: By improving design parameters and material selection, the model parameters allow the service life to reach 60 years or even longer to meet the long-term operation needs of advanced reactors.
Manufacturing: Standardizes the manufacturing process, welding requirements, heat treatment specifications, etc. of high-temperature reactor nuclear facility components.
Inspection: Clarifies the inspection items, inspection methods and acceptance criteria for high-temperature reactor nuclear facility components, including non-destructive testing, mechanical performance testing, etc.
Ensure nuclear safety: ASME BPV III Division 5 provides uniform technical specifications for the construction of high-temperature reactor nuclear facility components, which helps to ensure the safety and reliability of nuclear facilities.
Promote technological development: The formulation and implementation of this standard has promoted the advancement and development of high-temperature reactor technology, and provided technical support for the design and construction of new reactors.
