摘要

明确核电站管道的失效模式及其安全裕度是设计实践中的一个关键问题。本文对钠冷快堆薄壁三通进行了一系列动态失效试验。对薄壁三通在地震荷载作用下的破坏模式、动力响应特性、动弹塑性分析疲劳预测的准确性以及常规设计准则中包含的疲劳评估安全裕度等问题进行了讨论。

Ultimate Strength of a Thin Wall Tee for Sodium Cooled Fast Reactors Under Seismic Loads

Abstract It is a key issue to clarify failure mode of piping in nuclear power plants and its safety margin included in the design practice. In this study, a series of dynamic failure tests of a thin wall tee for sodium-cooled fast reactors was conducted. Some discussions related to the thin wall tee are provided on the failure mode under seismic load, dynamic response behavior, accuracy of fatigue prediction by dynamic elastic-plastic analysis, and a safety margin of fatigue evaluation which is included in conventional design rule.

期刊介绍： The Journal of Pressure Vessel Technology is the premier publication for the highest-quality research and interpretive reports on the design, analysis, materials, fabrication, construction, inspection, operation, and failure prevention of pressure vessels, piping, pipelines, power and heating boilers, heat exchangers, reaction vessels, pumps, valves, and other pressure and temperature-bearing components, as well as the nondestructive evaluation of critical components in mechanical engineering applications. Not only does the Journal cover all topics dealing with the design and analysis of pressure vessels, piping, and components, but it also contains discussions of their related codes and standards. Applicable pressure technology areas of interest include: Dynamic and seismic analysis; Equipment qualification; Fabrication; Welding processes and integrity; Operation of vessels and piping; Fatigue and fracture prediction; Finite and boundary element methods; Fluid-structure interaction; High pressure engineering; Elevated temperature analysis and design; Inelastic analysis; Life extension; Lifeline earthquake engineering; PVP materials and their property databases; NDE; safety and reliability; Verification and qualification of software.
